Senior Python Back End Engineer

Requirements

• Senior back-end engineer with a track record of owning ambiguous, multi-step projects end-to-end across API and UI (design → implementation → rollout → observability), comparable to tech-lead-level delivery on a business-critical system.
• Strong Python and Django (or demonstrably deep transfer: e.g. long professional experience in Java/JVM ecosystems plus substantial Python web work in production).
• PostgreSQL expertise : schema design, production database migrations, query plans, indexing, and fixing latency/regression issues-not only CRUD.
• Distributed systems and multi-service reality : async jobs/queues, events, idempotency, integration failures, and debugging across service boundaries.
• Proven impact outside "greenfield" only : experience in large or evolving codebases, modernization (framework/DB/search/runtime upgrades), or cost/performance work with measurable outcomes.
• Production mindset : on-call or equivalent experience, incident response, and prioritizing stability under operational load.
• Technical leadership without relying on title : examples of leading migrations, integrations, or architecture decisions; mentoring; and aligning engineers across teams.
• Clear written and verbal communication : design docs, ADRs, RFCs, or review threads that other engineers adopt as reference.
