The Role

Deliver complex features reliably while raising the technical bar of the team. At this level, your scope extends from individual features to subsystems — you own the outcome, not just the task.

Responsibilities
  • Design and implement complex features end-to-end; own subsystems and navigate existing codebases with architectural discernment, using AI tooling as an accelerant while applying your own judgment on correctness, security, and alignment with the system's direction
  • Participate in design reviews; propose sound technical designs and identify scalability, performance, and reliability risks before they become incidents
  • Scope and estimate accurately; deliver features from requirements through rollout and post-release monitoring; communicate risks early
  • Mentor junior and mid-level engineers through code reviews and pairing; provide substantive feedback that raises the quality of code around you
  • Drive improvements in team practices — testing patterns, observability, code organization — and push back on shortcuts that create long-term cost
  • Explain technical decisions clearly to both technical and non-technical stakeholders; represent engineering in product discussions with a security lens
What We're Looking For
  • You own outcomes, not just tasks — accountability motivates you
  • You build incrementally and surface risks early; you don't absorb uncertainty silently
  • You help people around you grow through reviews, pairing, and direct feedback
  • Production-grade Ruby on Rails; PostgreSQL with confidence in data modeling and query performance
  • Experience building integrations with external systems — REST/GraphQL APIs, webhooks, or third-party vendor connections
  • Familiarity with AWS, CI/CD pipelines, and deployment fundamentals
  • Familiarity with AI coding assistants (e.g., Claude, GitHub Copilot); you understand where they help and where they fail — hands-on use is a plus, critical evaluation instinct is required
Failure Modes We Screen Against

Strong coder, weak owner — ships code but doesn't own outcomes. Solo expert — hoards knowledge instead of sharing. An overconfident designer — proposes solutions without considering trade-offs.
