Description
What you'll do
- •Design, build, and operate backend services/APIs in Python/Django with Postgres/Redis.
- •Own outcomes, not tasks: refine scope, suggest trade-offs, and land increments that deliver value quickly and safely.
- •Model data and author migrations; tune queries and caching; manage background jobs/queues for high-volume workflows.
- •Evolve API contracts with FE; keep interfaces clear, versioned, and resilient to change.
- •Improve reliability and performance (timeouts, retries, idempotency, rate limits, pagination, backpressure).
- •Implement secure, multi-tenant patterns: auth, permissions/RBAC, auditability, and safe data boundaries.
- •Contribute to testing strategy (unit/integration), error handling, and graceful failure modes.
- •Partner with Support to investigate production issues and turn learnings into fixes and prevention.
- •Engage with our open-source community (issues, discussions) to understand real-world needs and improve developer experience.
- •Participate in architecture discussions and code reviews; mentor teammates and improve patterns across the codebase.
Requirements
- •Senior-level experience shipping production backends in Python/Django (or a close equivalent) and SQL.
- •Strong product sense: you’ve made scope/trade-off decisions and iterated based on real-world usage and feedback.
- •Depth in REST API design, relational modeling, migrations, and performance tuning.
- •Experience with background processing/queues (e.g., Celery/RQ/Kafka-backed workers) and operational concerns.
- •Clear written communication at a Senior IC level—concise RFCs/PRDs, actionable reviews, and crisp decision records.
- •Nice to have: GraphQL familiarity; Kafka/streaming; Spark/BigQuery; security/compliance exposure; multi-region architectures.
