Hi
About us
Job description
Requirements
- C/C++ is a must. Rust is preferred. We already have part of the core product written in Rust. If you know Haskell, please let us know. We don't use Haskell in our stack but like folks who know it.
- It is essential that if you have done courses or have work experience in Operating Systems, Distributed Systems, and Computer Networks.
- Good exposure to debugging (more than just `!analyze -v`). We suck at debugging here, so can use your help!
- Great version control (Git) hygiene and familiarity with CI/CD. Test- and issue-driven development (that's our new term).
- Candidate should prioritize documentation to meeting (can't emphasize enough). Who has time to talk and listen (and forget) when one can write and read? During the interview, we may ask you how to organize your notes, references, and knowledge (We use Notion and self-hsoted Gitlab).
- Familiarity with scripting languages such as Python or Nim is appreciated. Both languages are used heavily in DevOps here.
- If you don't know Java, that's +1 ;-p (just kidding).
