Contribute to architectural decisions that ensure code quality, scalability, and resilience

3–5 years experience as a full stack engineer in product-led environments

Deep familiarity with Ruby on Rails; some exposure to Elixir or willingness to learn

Confident building modern UI with React and contributing to backend systems

Comfortable working in fast-moving, ambiguous, startup-style environments

Clear communicator who works well across functions and cares about outcomes
