About the role

  • Take ownership of complex backend systems from design through production — including architecture, implementation, and long-term maintenance.
  • Lead technical discussions, drive engineering decisions, and document trade-offs clearly for the team.
  • Mentor junior and mid-level engineers through code reviews, pairing sessions, and structured feedback.
  • Identify systemic weaknesses in our infrastructure, propose improvements, and execute on them with minimal direction.
  • Collaborate across engineering, product, and data to align technical direction with business goals.
  • Drive improvements to observability, reliability, and performance across our backend stack.
  • Contribute to hiring by participating in technical interviews and helping define the engineering bar.

Requirements

  • 7+ years of backend engineering experience, with a track record of owning critical systems in production.
  • Deep expertise in Java (Spring Boot) and strong familiarity with Python; comfortable navigating a polyglot codebase.
  • Proven experience designing distributed systems — event-driven architecture, microservices, data pipelines.
  • Strong command of PostgreSQL and experience working with cloud-native infrastructure on AWS.
  • Someone who has been through hypergrowth or scale challenges and has the scars and instincts to show for it.
  • A multiplier: you make the engineers around you better through your presence, feedback, and technical clarity.
  • Comfortable operating in ambiguity — you can shape requirements, not just execute on them.
Benefits
  • Equal-opportunity employer
  • Welcoming applicants from all backgrounds
