About the role

  • Be accountable for the technical health, scalability, and long-term sustainability of a defined backend subsystem or domain.
  • Lead complex technical initiatives spanning multiple cycles with end-to-end responsibility from problem framing to measurable stabilization.
  • Design robust backend architectures and implementation plans that reduce operational risk and improve system performance.
  • Break down ambiguous or loosely defined problems into clear technical strategies with explicit trade-offs.
  • Collaborate closely with Engineering Managers and Product to align technical solutions with business priorities and customer needs.
  • Improve backend reliability by proactively identifying systemic risks, technical debt, and architectural bottlenecks within the domain and drive remediation before they impact teams or customers.
  • Contribute hands-on to the backend codebase, delivering high-quality, secure, well-structured, and maintainable code.
  • Raise engineering standards through thoughtful code reviews, documentation, and technical guidance.
  • Mentor mid-level and senior engineers across the Backend pillar, supporting their growth toward greater technical ownership.
  • Support production stability by actively participating in debugging, root cause analysis, and long-term remediation efforts.
  • Contribute to evolving backend development practices, testing strategies, CI/CD workflows, and performance optimization efforts.
  • Act as a technical reference point within a defined backend domain, fostering alignment and reducing cross-team friction.

Requirements

  • 9+ years of relevant experience as a Backend Engineer, with demonstrated ownership of complex systems or subsystems.
  • Strong experience with Ruby on Rails (preferred) or comparable backend frameworks.
  • Proven experience designing and implementing scalable APIs and backend services.
  • Strong expertise in PostgreSQL and database design; familiarity with NoSQL or vector databases (e.g., Qdrant, Pinecone, or Weaviate) is a plus.
  • Deep understanding of software design principles, testing strategies, CI/CD, and backend reliability practices.
  • Experience working with distributed systems, background jobs (e.g., Sidekiq), caching layers (e.g., Redis), and cloud infrastructure (AWS preferred).
  • Familiarity with modern AI/ML services or data-intensive workflows is desirable.
  • Experience leading technical initiatives or large refactors across teams is highly valued.
  • Strong problem-solving skills and ability to operate effectively in complex, evolving environments.
  • Excellent written and verbal communication skills in a collaborative, remote-first setting.
  • Bachelor’s or Master’s degree in Computer Science or equivalent practical experience.
