Dex; Greater London; On-site; GBP 70,000 - 110,000; Full time

Job summary

Dex, a partner company, seeks a backend engineer to build a mission-critical Rust/Python backend for real-time defence intelligence. You will design features, address extreme conditions, and ensure reliability through rigorous testing and benchmarking.

You will work on a Rust/Python stack with opportunities to learn from prominent open-source contributors, solving complex distributed systems challenges where degradation can occur by design.

Qualifications

• This role requires strong backend development experience in a systems language (Rust, Java, Go, C++, or similar).
• Proven ability to build and operate complex distributed systems with a focus on failure modes.
• Experience with edge computing, latency optimization, or platform engineering is highly valued.
• Familiarity with REST, GraphQL, gRPC/Protobuf, and Arrow interfaces is preferred.

Responsibilities
