MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time

MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Absinthe Labs | Full-Stack Engineer | REMOTE / NYC Hybrid | Full-Time

About us:
Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.

The problem we’re solving:
Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.

We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.

Why it matters:
This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.

The role:
We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions

Get involved:

• Explore product functionalities at: https://guides.absinthe.network

  - Explore the Adapter Library docs: https://docs.absinthe.network/

  - Join our Slack community to hack on adapters and connect with the team:

Jupiter is building a better approach to healthcare for 80 million working age Americans like you and me.

Censys | Product Detection Engineer | Full Time | Remote US

Hey everyone. I'm a Principal Engineer at Censys. We are the source for Internet Intelligence. We conduct a full internet survey every day and turn that into actionable data for folks to identify risk, research emerging internet threats, and make the internet a safer place. If you also get a bunch of data breach mailers in your mail box every year, you're familiar with the impact of security breaches at tech companies. We're trying to put a stop to that by helping companies understand their risk and mitigate it.

HQ is in Ann Arbor, MI, but we're all over the US. We're looking for a Product Detection Engineer. Organizations around the world depend on Censys to help them identify threats in their infrastructure. This person will be involved in helping fingerprint and identify relevant risks using Censys data so that response teams can close vulnerabilities faster.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs, and our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS or AI company, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.

Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

Phrasing.app | Co-founder | EU Remote | Elixir | Clojure

Phrasing is a language learning app built by a polyglot, for polyglots. It was designed to be language agnostic, and currently fully supports over 80 languages. It brings a beautiful, simple, and addictive [1] learning experience to languages big and small, and helps users learn 2-10x more in the same amount of time [2].

The tech stack is a ClojureScript PWA on the front end, and an Elixir umbrella application on the backend. The data processing happens in Broadway pipelines, and are horizontally scalable with FLAME. All of the data is stored in Postgres, and most of the communication between the client and server happens with a custom local-second sync engine à la Linear.app.

The company is bootstrapped and bespoke. There’s no investors, there’s no AI generated code, no shadcdn UIs. I miss the days of the early internet, and acutely feel the mass enshittification of the web. I’m really trying to do something different with the experience as well as the business, all in hopes to bring back a little bit of that wonder that was so prevalent in the days of the early internet.

The app is all working, the experience is great, and the onboarding was just finished. I’ve been using the app now to successfully learn 18 languages [3] and it’s truly a joy to use. Just finishing up the new site [4] after feedback from our last launch and getting ready for more launches [5]. The new video has been getting some pretty rave reviews and is a good gentle introduction to the app [6]

For me, this app is a dream app. This tech stack is a dream tech stack. This company is a dream company. It’s hard to believe I’m the only one these would all be true for.

I’m looking for someone who believes in the product, mission [6], and tech to come in and help me turn this functioning application into something truly great. No experience is required — just a dedication for your craft, and the willingness to take a chance in something you believe in.

If you feel that this post was written for you, please write me a well written personalized CV to hn at phrasing dot app. Low effort applications will not receive a response regardless of your CV.

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t always go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

Erdos Miller | Data Wrangler (Part-time → Full-time growth) | Remote (US preferred, flexible otherwise)

We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.

We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role.
What you’ll do

Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools.
Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL).
Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell).
Deliver insights via live web apps where data isn’t static — it’s explorable.
Tech we use
Python, SQL (PostgreSQL/MySQL), S3, modal.com.
Bonus: React/web dev experience to shape customer-facing real-time tools.
Why you’ll like it here
You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role.
If this sounds fun, email [email protected] with your background and what excites you about wrangling data.

StorPool | Senior Software Engineer - Storage Core (C/Linux) | Remote (UTC-1 to UTC+5) | Full-time | Multiple roles

We're looking for a Senior Software Engineer to join our Core Storage team. You'll tackle genuinely hard problems: writing custom Linux drivers, optimizing lock-free data structures at nanosecond scale, building fault-tolerant distributed algorithms, and debugging issues that go all the way down to kernel internals. This isn't CRUD work - it's systems programming at its most challenging.

Competitive salary, meaningful time off, yearly education budget. Our most senior engineers spend their time solving the hardest technical problems hands-on, not in meetings.

If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk.

Oils (https://oils.pub/) | Language Engineer / Debugger of Other People’s Cursed Shell Programs / Writer | REMOTE (non-US) | 50 euros/hour

Oils is our upgrade path from bash to a better language and runtime.

We’ve been awarded a 4th grant from https://nlnet.nl, and our focus is to show that OSH can be the ONLY shell on a Unix system, which is hard

It looks like we will reach this goal! Other than me, there are 4 people working PART TIME on this, and we can use more help.

If you like hunting down difficult bugs, and are skilled at Unix and Python, this could be a good fit.

Most bugs are too hard for 1 person to fix by themselves, so communication is important. And writing good test cases is important.

We’re also paying people to do polished writing, since we'd like to spread the word

Starting from 131, we’re down to 41 disagreements between OSH and sh/ash/bash, when building ~1600 packages in Alpine Linux

https://op.oils.pub/aports-build/published.html

Anyone who's not “scared” of these bugs is probably a good fit, and you can do as much or as little as you like. This is also an opportunity to get deeper into the interpreter

Communication happens on Zulip, and we also have video meetings approximately every 2 weeks

I'll have a blog post explaining this work soon, but feel free to e-mail me if this (unusual) job matches your interests. Any questions are very welcome, and you can dip your toes in to see if it works for you

I wrote this page a few years ago to help people assess the fit: https://github.com/oils-for-unix/oils/wiki/Where-Contributor...

The job is remote-only, and we slightly prefer non-US contributors due to our funding

Tech stack: Python, Shell, perhaps C++
