About the role

We are looking for a senior generalist engineer. You will work across PHP, AngularJS, Go, Node, and SQL. Strong in PHP, able to pick up Go and Node as needed, able to work in a system you did not write. You own features from design to production, write short design docs before non-trivial work, and work directly with product and QA. You already use agentic coding tools daily. Senior here is not about years of experience. It is about how you operate, technically and with people: Takes the hard tasks. Picks up the unclear, risky, or unpopular problem and drives it until it is working in production for real users. Done means live, not a ticket status. Flexible in solutions. Has more than one way to solve a problem and chooses based on constraints, not habit. Moves fast when it matters. Knows when to ship quickly and when to slow down, and can tell the difference. Communicates. Explains decisions clearly, keeps people informed, raises problems early instead of late. Gives and takes feedback. Direct, specific, constructive. Not defensive when the feedback comes back. Owns outcomes. Not just the code, but whether the thing actually works for the people using it.

Solid with relational databases

Communicating directly with product, QA, and non-technical stakeholders. Working English, spoken and written. Nice to have Splitting a monolith into services in production.
