Order.co has raised $50M in funding from industry-leading investors like MIT, Stage 2 Capital, Rally Ventures, 645 Ventures, and more.

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.
