About The Position
- Track record of delivering various features in large-scale applications or core systems with at least 5 years of experience. If you've written code in big data applications handling multitudes of data or real-time events, you're in.
- Experience writing multi-component systems or micro-services, with architectures requiring efficient inter-application communication. If you know what Kafka is, and think it's the bee's knees, we will think the same of you.
- Experience writing in a high-level language such as Go, C, Rust, Python, Ruby, etc.. If you're already writing Go, or spent a weekend debugging the worse memory leak ever, that's a big plus.
- Experience writing APIs (either RESTful or not) and RPCs. If you've broken backwards compatibility for your customers once, and dealt with the fallout, we want you (to deal with the fallout again).
- Experience with RDBMS systems (e.g. MySQL, PostgreSQL, Oracle, SQLite) and/or NoSQL databases (e.g. MongoDB, Redis, Cassandra, Couchbase).

- Are you a free software/open source nerd? Do you maintain open source projects? Are you a Hacker News reader? Do you remember the days when you had to compile your own Linux kernel? Do you believe it should be called GNU/Linux? Have you ever been in a fight with an Emacs user? Are you an Emacs user? Well, we have the job for you!
