Ideal Candidate

You're a Rails traditionalist who appreciates working in a mature, stable codebase. You understand ERB / HAML and don't see them as "legacy" but as proven, reliable tools. You write tests first (TDD), think from user's perspective, and code with intention. You take ownership of your code in production and proactively monitor its impact. You have solid experience and third-party APIs with proper error handling. You can explain complex technical concepts to support teams and enjoy helping others understand your work. You provide accurate sprint estimations, enjoy maintaining complex systems, and take pride in keeping production stable while adding value through new features.

What Makes This Role Different

Unlike roles focused on "modernization" or "migration," this position is about mastery of traditional Rails with full existing web app ownership . You'll work in ERB / HAML views, build features with Rails patterns, maintain a platform that serves customers reliably, and own your code from development through production support. If you prefer depth over trends, stability over constant change, and take pride in owning what you build, this role is for you.
