• Act as a force‑multiplier for your team by defining and advocating technical solutions and operational processes.
• Own your team's operations and availability by ensuring proper monitoring, triage rotations, playbooks, policies, testing and alerting in place for on‑call and “keep the lights on” efforts.
• Foster a culture of quality and ownership by setting code review and design standards and advocating them through writing and tech talks.
• Help develop talent on your team through feedback, guidance and leading by example.

What We Look For

• Proficiency in designing, developing and launching backend systems at scale using Python, Kotlin, AWS, MySQL, and Kubernetes.
• Experience delivering major features, system components or deprecating existing functionality with a clear technical and execution plan.
• Ability to write high‑quality, easily understood code.
• Comfortable working in ambiguity from low‑level language idioms to large system architecture.
• Demonstrated growth and impact through iterative feedback from engineering and cross‑functional peers.
