TrendSpider is a professional tool for those who trade anything from stocks to cryptos. We provide smart retail traders, financial advisors and hedge funds with the market research and algo trading platform.

We need a Node.js engineer who’s going to primarily deal with data feeds (market data and alternative data).

1. Connecting new data types and maintaining existing pipelines
2. Improving observability in data import pipelines
3. Working on business logic which is necessary for data to work in charting, scanning, backtesting, custom JS scripting etc.

Here are the skills required in order to do the job well:

• Experience establishing cloud infrastructure via Terraform. AWS Lambda + SQS is a bare minimum.
• Strong expertise in Node.js. At the very least, you need experience profiling, debugging a memory leak and an event loop jam in a Node.js service. Some services handle tens of thousands of messages per second, some pipelines handle gigabytes of data with limited RAM, that’s why.
• Experience working with PostgreSQL and MongoDB with no ORMs.
• Experience dealing with massive data (both “read a lot” and “write a lot”) in PostgreSQL.
• Strong understanding of ideas of both OOP and functional programming. We use both, depending on a component and a goal.
• Capability for testing your work well. Both writing automated tests (units, function, e2e) and running checks by doing what customers do.
• Capability for figuring things out. All data vendors are different, all APIs are different and every kind of data has its own scale.
• Capability for building simple solutions for complex problems. Simplicity of solutions is the king here.
• Hands-on experience trading or designing strategies will be a significant bonus.

You’ll be dealing with a microservice architecture (30+ microservices) where the vast majority of services run on Node.js. Microservices either provide HTTP REST APIs using Express and Fastify (no Next.js, no GraphQL) or use Websocket. Cloud infrastructure is AWS, CI/CD pipelines are on Gitlab and Bitbucket. Container orchestration is K8s and Docker Swarm. Data pipelines mostly run on AWS Lambda.

Code is all ECMAScript. Quality of code is high, but in some data pipelines it’s rather acceptable. There are no variables named “x”. There’s a coding convention. Overall, we value solving problems and delivering value to our customers way above using this new fancy technology just for the purpose of using it.

The workflow is a lightweight mix of scrum and kanban, with a low level of formality. There’s a QA team, but engineers test their work thoroughly too. You’ll be supervised in the beginning. As soon as we get on the same page regarding values in engineering, you’ll be having less and less supervision, until you get to a point when you will make most of the decisions yourself. The team is all remote, from Argentina to Ukraine. Languages are English and Russian. Speaking Russian would be a bonus, but not a must have.

The hiring process is short and straightforward. First, a few emails, then one interview call with 1-2 people and that’s it.

While we expect you to primarily deal with the data pipelines, this position offers you a number of directions for growth. You will have the opportunity to work with highly loaded components (i.e., real time market data firehose intake) and fairly sophisticated architecture. You will also have a chance to work with active traders and learn about markets and trading as a whole, backtesting and algorithmic trading. You’ll be able to work on business logic related to algo trading if you’re interested and capable. In general, if you’re interested in trading and want to e deep, then it’s the right place for you.

About Status

Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.

With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.

As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.

As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol; the p2p communication layer for Web3.

As a team, Status has been completely distributed since inception. Our team is currently 200+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.

We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization’s priorities.

The role

DevOps is a buzzword, but it’s also generic enough to encompass the breadth of tasks required in supporting development teams. There are many ways to make the lives of developers easier, and everyone has their own best way, which also means every team has their own way. There is no perfect way to make everyone happy with the same thing.

Supporting developers involves debugging obscure bash scripts from years ago that nobody remembers. It means biting on a piece of wood and using data formats turned programming languages like YAML to configure CI jobs. It means tracking down minute differences between releases of packages and libraries causing unexpected crashes. It means rewriting the same Dockerfile for the 5th time to allow a project to use one more obscure library. Or tracking down absurd race conditions of multi-threaded tests running in parallel on the same host. Or pulling your hair out at a bug only to realize it works fine after the CI worker host is restarted.

But fundamentally it means wrestling it all into submission and making it run smoothly… at least for as long as you’re there.

If you have the guts to fight against entropy and deterioration of the reality we inhabit, then you just might also be crazy enough to enjoy the struggle while it lasts, and appreciate the eventual fruits of our labour, if you value privacy, freedom, and transparency. You might even make some money, and learn a bit from all the exceptional engineers working here.

Who you are

• You have strong Linux Fundamentals:
  • Distros and package managers
  • Good understanding of process management
• You have programming experience:
  • At least a few languages and showing the ability to learn
  • Bash as a minimum; Python would be helpful
• You have experience in Continuous Integration:
  • Jenkins CI - Pipelines are written in Groovy
  • GitHub Actions - PR builds, mostly
• You have experience in Security:
  • Good understanding of OpenSSH
  • GnuPG for encryption of secrets and backups
• Distributed Systems:
  • Experience running Ethereum nodes
  • Knowledge of Layer 2 scaling solutions

Compensation

We are happy to pay in any mix of fiat/crypto.

About Status

Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.

With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.

As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.

As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol; the p2p communication layer for Web3.

As a team, Status has been completely distributed since inception. Our team is currently 200+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.

We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization’s priorities.

The role

DevOps is a buzzword, but it’s also generic enough to encompass the breadth of tasks required in supporting development teams. There are many ways to make the lives of developers easier, and everyone has their own best way, which also means every team has their own way. There is no perfect way to make everyone happy with the same thing.

Supporting developers involves debugging obscure bash scripts from years ago that nobody remembers. It means biting on a piece of wood and using data formats turned programming languages like YAML to configure CI jobs. It means tracking down minute differences between releases of packages and libraries causing unexpected crashes. It means rewriting the same Dockerfile for the 5th time to allow a project to use one more obscure library. Or tracking down absurd race conditions of multi-threaded tests running in parallel on the same host. Or pulling your hair out at a bug only to realize it works fine after the CI worker host is restarted.

But fundamentally it means wrestling it all into submission and making it run smoothly… at least for as long as you’re there.

If you have the guts to fight against entropy and deterioration of the reality we inhabit, then you just might also be crazy enough to enjoy the struggle while it lasts, and appreciate the eventual fruits of our labour, if you value privacy, freedom, and transparency. You might even make some money, and learn a bit from all the exceptional engineers working here.

Who you are

• You have strong Linux Fundamentals:
  • Distros and package managers
  • Good understanding of process management
• You have programming experience:
  • At least a few languages and showing the ability to learn
  • Bash as a minimum; Python would be helpful
• You have experience in Continuous Integration:
  • Jenkins CI - Pipelines are written in Groovy
  • GitHub Actions - PR builds, mostly
• You have experience in Security:
  • Good understanding of OpenSSH
  • GnuPG for encryption of secrets and backups
• Distributed Systems:
  • Experience running Ethereum nodes
  • Knowledge of Layer 2 scaling solutions

Compensation

We are happy to pay in any mix of fiat/crypto.

2. Paid task

We are building the support platform for developer tools. Think Linear meets Stripe for support: A pro tool that’s delightful to use right out of the box, and powerful to build with.

Support might seem boring at first, but we think it’s one of the most interesting products to work on. Support tools are the very definition of a productivity tool. They’re inherently multiplayer, high volume and collaborative with unique technical demands. Plus, every company that has customers, has customer support - a huge software market.

We’re looking for an experienced backend engineer to help us lead and shape all things backend at Plain. You'll be joining an intentionally small, commercially savvy, and product-centric team. Everyone on our team is technical, commits code, and speaks to customers. We maintain complete internal transparency on almost everything, and are just as driven by building a great product as we are by building a great company.

What you'll do

• Shape our architecture. You'll work on some of our most complex technical challenges and help others do the same. You'll help decide how we build things and what we prioritise as a product and engineering team.

• Guide product direction: We believe that all engineering decisions are product decisions, and vice versa. You'll collaborate with everyone on the team to decide what we work on and why, and help build Plain to be the best product and business it can be.

• Help build a small team with outsized impact: We want to build an intentionally small company because we believe that small teams are more efficient than big teams. You'll play an integral role in shaping our product, culture and ways of working to enable this.

• Create a stellar developer experience. You'll help make sure the experience of building with Plain second to none. You'll play a key role in everything from how we structure our data model through to designing our APIs and writing documentation.

This is a great fit if you…

• Enjoy being hands-on with a focus on writing code and shipping things. There is a lot to build.

• Want to work day-to-day in a full-stack Typescript and serverless codebase.

• Want to work as part of a small, multi-disciplinary team and collaborate closely with others.

• Want to work on something (nearly) greenfield. The biggest product and company decisions still lie ahead of us.

• Enjoy the autonomy, uncertainty and unpredictability that comes with an early stage company.

This won't be the right role if you…

• Want to manage a team. Given our team growth plans, this is unlikely to be a need in the next 12-24 months.

• Mainly want to deepen your expertise in a particular technology or domain. This role is best for product and business focused engineers.

• Want all of the benefits that come with an established tech company - top-end comp, free drinks and lunches, etc.

• Want a traditional product team set up, with a predictable roadmap, clearly scoped out tickets, a PM, and so forth.
