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.

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.

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.
