Job description

Full‑Stack Rust Software Engineer - Allocation & Disruption Optimisation

Join a venture‑backed startup re‑imagining how airlines and airports run.
We're recruting for an exciting tech company building a unified operations platform that helps front‑line agents, planners, and engineers keep flights on time, handle disruptions in real time, and deliver a seamless passenger experience. As an early team member, you'll own end‑to‑end delivery-shaping architecture, shipping production code, and seeing your work used by operators across the world.

What you'll do

• Build robust back‑end services in Rust using gRPC and Postgres.
• Design and evolve a real‑time optimiser for allocation & disruption use cases (think: resources, schedules, constraints).
• Model complex operational rules and encode them into scalable optimisation logic.
• Ensure reliability and observability across services (metrics, tracing, alerting, SLOs).
• Design flexible, future‑proof data models for a diverse and intricate industry domain.
• Contribute to the front end when needed (Flutter/Dart; occasional React/TypeScript).

Must‑have skills

• Rust: 3 years+ commerical develpment experience
• Modelling / Optimisation: Hands‑on experience modelling systems and solving optimisation problems.
• Rust: Comfortable reading and writing idiomatic Rust.
• Relational Databases & SQL: Proficient with Postgres (schema design, performance).
• Independent Delivery: Capable of owning features end‑to‑end with minimal oversight.
• 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.
• High autonomy: Own features end‑to‑end and shape architecture from the ground up.
• Meaningful upside: Competitive salary plus equity as we scale.
• Remote‑first culture: Work anywhere in the UK with flexible hours and a supportive, high‑trust team.
