What do we do?

Chainflip is an efficient swapping protocol that enables users to swap native assets across different blockchains with excellent pricing.

We’re not yet another bridge. Our protocol design removes the need for wrapped tokens. We use MPC (Multi-Party-Computation), and in particular, TSS (Threshold Signature Schemes) to create aggregate keys held by a permissionless network of 150 Validators. These validators control simple smart contracts/wallets called Vaults, on multiple blockchains simultaneously. On top of that, we developed our own substrate-based application-specific blockchain — the Chainflip State Chain — to track balances, process events, and execute instructions.

This is an exciting challenge that we’ve been working on for 3 years now with our growing engineering team of 15. While our heart beats in Berlin, we champion flexible work rhythms, encouraging both in-office collaboration and the freedom of remote stints.

What’s the Job?

We are looking for a (Senior) Software Engineer to join our Protocol Team. The Protocol team builds the core of the Chainflip protocol, consisting of two key components: the Chainflip Node and the Chainflip Engine. The former is a substrate-based blockchain node. The latter is a companion process that communicates with the outside world and relays information to and from other Blockchains.

Almost all of our codebase is written in Rust. While some experience with Rust would be beneficial, this role is open to talented and motivated Engineers from any language background as long as you are willing and able to learn quickly.

Some attributes we look for when hiring:

• Agreeableness: This is particularly hard to quantify, yet particularly important to us. How well do we think you would fit with the team? Do we feel like we want to work with you day-in, day-out?
• Determination: When presented with a challenge, you try to solve it to the best of your abilities.
• Humility: Despite your determination, you know when to take a break and ask your colleagues for help. You are receptive to feedback and constructive criticism.
• Initiative: You don’t wait around to be told what to do, you pro-actively investigate issues and suggest improvements.

We are open to candidates of all backgrounds, however there are of course some particular skills and experience that would be beneficial:

• Interacting with blockchains: Whether it’s Ethereum, Bitcoin or anything else, an appreciation of the particular difficulties and edge cases would be very useful.
• Building and debugging distributed systems: Chainflip relies on a myriad of actors cooperating to process high-value currency transfers. We need to make sure that our system is only as complex as it needs to be, and that every edge case and error path is covered.
• Experience working with large and complex code bases: Chainflip has grown immensely since its inception and we plan to continue. If you can bring experience of managing the complexity of a large codebase, particularly in Rust, you will be well-received.
• Experience with systems that rely on asynchronous code: The Chainflip Engine makes heavy use of Rust’s async/await primitive and tokio ecosystem. Knowledge of tokio or a similar framework would flatten the learning curve of any new hire.
• Rust: While knowledge of the language is by no means a defining criterion for the role, if you do have deep knowledge of Rust, in particular running Rust in production, we want to hear about it.

About the Company

We are a Berlin-based team with our own office space in the heart of Kreuzberg, but we have remote workers in a couple of countries in Europe, a new office in Dublin, and a team in Melbourne, Australia.

We meet up as a whole team once a year (last time it was in Cape Town), have a very open and flexible culture, and enjoy meaningful personal connections with one another. Our team has a erse range of backgrounds and experiences to share, and we hope you’ll be able to contribute with yours too.

We offer all Berlin-based employees standard employment contracts under German law and the following list of benefits:

• 🪙 Equity/Tokens: Invested in Chainflip? We invest in you, too.
• 🚉 Public transport: Enjoy the “Deutschland Ticket” subscription
• 🏊🏽‍♂️ Stay Active: We have you covered with an Urban Sports Club membership
• 🎓 Learning: Annual budget for personal development (eg Udemy courses)
• 📚 Language courses: Go multilingual with our sponsored courses
• 🌴 Loyalty Rewards: Extra holidays for every year working at Chainflip. It is very important to us that our team members are well rested and take the time to recharge from time to time
• 🍲 Team Vibes: From in-office cooking sessions, sports like volleyball and padel, to music streams and events, we ensure you’re always connected and engaged. After all, it’s the collective spirit that makes Chainflip unique.

You can read more about Chainflip Labs and the team culture here.

Who Should Apply?

This is the role for you if:

• 🇪🇺 You’re based in Europe and open to calling Berlin your new home.
• 💼 You boast 6+ years of development experience.
• 🚀 Decentralization and blockchain technology spark your interest.
• 🔧 You’re familiar with crafting and scaling robust systems.
• 📚 Eager to broaden your horizons into the realm of Web3 with us.
• 💡 Beyond tech, your communication, teamwork, and problem-solving abilities set you apart.

A quick note: If you don’t check every box but are passionate and bring unique perspectives, we still want to hear from you! We deeply value erse experiences and talents. Our offered salaries and token packages reflect the depth of your skills and experience. With your application, kindly indicate your expected salary range.

The Process

Please submit your CV for review. A screening call will be conducted by our COO. The next steps are a more technical chat followed by a take-home challenge which will then be expanded upon in a 1-hour in-person or remote code interview. Then you will have a more informal meeting with some other members of the team, including the CTO and CEO. This whole process can take as little as a week.

Equal Opportunity at Chainflip

We recognize the inherent value of building with a erse and inclusive team of Flippers. Our team thrives when given the flexibility and autonomy to work in ways that best suit their inidual lifestyles and needs. If accommodations are required at any step of your application process, do let us know.

Finni Health empowers autism care providers to start, run, and grow their own practice. 🦊

The autism care industry is growing rapidly due to increasing diagnosis rates and landmark legislation requiring payers to cover care in every state. This has caused private equity to take over the market, with over 200 M&A deals in the past decade. This cash grab not only hurts providers, who are overworked and underpaid, it also hurts quality of care. Providers want a world where they can have the freedom to focus on their patients, but starting their own practice is costly.

We built a platform designed for autism care providers to start, run, and grow their business. Providers with Finni can launch their own practice in 2 weeks. When they join, they instantly get access to our insurance network. From there, our platform allows them to manage patient data, schedule appointments, and get paid.

We are backed by top-tier investors such as General Catalyst and YCombinator.

How we work 💻

We’re a hybrid team, with team members all across North America. Slack, Notion, Figma, Meets and email are our main tools of collaboration. When it's safe, we may add local office options in cities with more than one local team member.

You'll be responsible for driving projects from concept to completion in an environment of autonomy and creativity. And since we're early, you'll have an opportunity to shape not just our product, but our culture: who you work with, and how we all work together.

As a founding member of the team, you will be making foundational decisions that will be critical to the company’s success. Founding engineers will work incredibly closely with the cofounders, investors, and customers to deeply understand the problem and build the best product. We’re iterating on our MVP and there is a ton of work that needs to be done. Our stack is:

React, Express, Node.js, GCP.

About you 👋

We're looking for a product-minded engineer – someone who actively engages with the 'why', and has the thirst for using technologies to leapfrog human problems. Someone with a strong track record of bringing products to life. You should have some experience in a backend framework (like Node), and with the staples of full-stack web development: HTML, JavaScript, and CSS.

An early stage startup has to strike a balance between moving fast, and building for the long haul. So we're looking for someone who can minimize scope, prioritize ruthlessly, and implement rigorously.

You take ownership and you see things through. You can take a stand yet commit even when you disagree.

You don’t need heavy direction. You enjoy the grey. You like open-ended problems, and thrive in the face of uncertainty – the elements of a startup environment.

How We Hire

We have a merit-based recruitment process because we want to hire the best people. So University degrees aren’t a requirement for any role, and we have no such thing as a ersity quota.

Your application will be considered holistically. For example, someone with a marketing degree applying for an influencer management role but no industry contacts would not be chosen over a high school dropout that has a deep network and a history of structuring great deals.

On the other hand, a degree could be a big plus for a research assistant application as it proves your ability to persevere and focus on high-level tasks. It’s all about context.

So if you think you’re the best, it doesn’t matter who you are or where you come from — introduce yourself.

After submitting an initial application, here’s the usual process for shortlisted candidates:

• Let your skills shine through a technical assessment
• Join us for a 60 min. interview and Q+A with a Senior Dev from our team
• Meet our CTO in a final 20 min. chat

We try our best to respond to every application. But sometimes this isn’t possible due to the large application volume. If you don’t hear from us in 2-3 weeks, it means that we’ve most likely progressed with other candidates.
