Problem-Solving Mindset: Thrive in fast-moving startup environments.
Nice-to-have extras

Aviation domain knowledge (airline or airport operations).
Back-end engineering experience in modern, service-oriented systems.
Flutter/Dart and/or React/TypeScript exposure.
gRPC/Protobuf (unary & streaming).
Apache Arrow/Parquet for high-performance data workflows.
Observability tooling: Prometheus, Grafana, CloudWatch.
CI/CD & containerisation: GitHub Actions, Docker (or similar).
Why this role

High impact: Every release helps real teams keep operations running and passengers moving.
