Requirements - Several years of production backend engineering experience using a typed or otherwise disciplined programming language. - Comfortable working with SQL. - Strong understanding of idempotency and the challenges of distributed systems. - Experience operating backend software in production and reasoning about reliability under failure conditions. - Ability to explain technical concepts clearly to clients and teammates.
