Software Developer, DevEx (Stateful Systems)

Role overview Build internal services and tools that help software teams safely operate databases, queues, caches, streaming systems, and a data lake. The work centers on availability and developer productivity: turning specialist operational tasks into self-service capabilities that product engineers can adopt and use with confidence.

Requirements - Strong backend engineering skills in a general-purpose language such as Python, Go, or Java, including experience building and testing production services and APIs. - Hands-on experience running relational databases in production, designing schemas, shipping migrations, investigating slow queries, and selecting indexes. - Understanding of distributed systems concepts such as retries, idempotency, consistency, and failure handling. - AWS experience, including IAM, RDS, and networking fundamentals, plus infrastructure-as-code experience with Terraform. - Experience building or maintaining CI/CD pipelines and operating production systems, including on-call response and blameless postmortems. - A track record of building internal tools such as CLIs, APIs, or automation with attention to usability and adoption.
