Senior Backend Engineer 🔗
- Location: RemoteSend your CV
Join us in our mission to build tools for blockchain developers, with a special focus on Ethereum and ZK. We're in the early stages, presenting an opportunity for you to have a massive impact on both our product and the company's culture. Our partnerships with leading ZK Rollups, including Starknet, Aztec, and Miden, place us in an advantageous position to succeed.
Why you should care
- Learn from the best and brightest. We work directly with the core development teams of some of the most cutting-edge ZK blockchain ecosystems, including Aztec, Miden, and Starknet.
- Build a product people will actually use and love. After announcing Walnut at the end of 2023 during StarkNet Istanbul (and winning the hackathon 🙌), we received strong interest from top StarkNet companies such as Argent, Briq, and StarknetID. They all said they "definitely need a transaction debugger for their day-to-day" and are waiting for V1 to go live.
- Live and work wherever you choose. The entire team comprises only developers, and we are fostering a remote-first, developer-friendly culture. This involves having very few meetings and numerous transparent, well-documented asynchronous conversations. We are huge fans of 37signals and their books.
- Increase your odds of success. Walnut is well-capitalized and officially supported by the Starknet Foundation, which recognizes the need for a transaction debugger. Our runway is healthy, and we have strong partners behind our backs.
- Build it from the ground up. The core tech stack and infrastructure are being developed, and you can be part of the design process.
- Become our CTO. It's a role we will need to fill soon. If things go very well, it can be yours.
Who are we looking for
- At least 5 years of experience as a Full-stack / Backend engineer.
- Excellent programming and technical skills. Experience with Rust is a bonus.
- Great understanding of Ethereum and its rollup ecosystem, with focus on ZK Rollups.
- Great communication skills and experience working in a fully remote, asynchronous culture.
- This role is available only to candidates in Europe to make it easier for us to occasionally meet in person. We plan to host two offsites per year in beautiful places around Europe.
About Walnut
We are a small team of five developers seeking to hire two more backend developers to join our ranks. We are excited about Bitcoin, Ethereum and ZK Rollups. We care about Security and Monitoring, and you can learn more about our vision here.
Our primary product, Walnut, is a transaction debugger and simulator for Starknet. Additionally, we work on several other projects focused on monitoring, security, and transaction simulations.
We also created cairovm.codes, a web-based playground for learning and debugging Cairo programs and exploring the Cairo VM execution trace. The app has been recognized by Starkware and is now integrated as the official Cairo playground at cairo-lang.org.
We are VC-backed and have a healthy runway. We are not just another "crazy-excited", "move-fast-and-change-direction-every-day", "VC-backed-and-soon-to-die" startup. We have been around for a while and have experienced our fair share of successes and failures.
What you will work on
You will spend approximately 100% of your time building. The only regular meetings we conduct are standups and short bi-weekly retrospectives. We focus on building, learning and iterating. You will mainly:
- Work with Rust on one of our products, including Walnut.
- Collaborate with core-developers at Starkware, Aztec, Miden and other leading ecosystems.
- Brainstorm and explore new solutions to problems faced by protocol or blockchain developers.
Summary
This opportunity is tailored for highly skilled, experienced developers who are passionate about blockchain technology and looking for a chance to build a lasting product that will solve real needs.
