Principal Backend Engineer - Edge Real-Time Systems

Dex; Greater London; Hybrid; GBP 120,000 - 180,000; Full time

Job summary

Dex is seeking a Backend Architect to define the technical direction for mission-critical systems servicing real-time, AI-powered platforms. You will own backend architecture for distributed services across constrained networks and intermittent connectivity.

The stack is Rust and Python, but the team values language-agnostic approaches. You will write RFCs, mentor engineers, and drive cross-team opportunities while ensuring graceful degradation in demanding operational settings.

Qualifications

• Experience owning architecture for critical systems.
• Proven capability in edge computing or distributed systems.
• Backend experience in Rust/Java/Go/C++ with high reliability.

Responsibilities

• Own architecture and technical direction for backend systems that other engineers depend on.
• Define and implement solutions for intermittent connectivity, resource-constrained embedded compute, air-gapped fleets, and low-trust networks.
• Drive technical decisions and RFCs for fleet coherence, software versioning over low-bandwidth radios, and trust boundaries in unsecured environments.
• Ensure graceful degradation and reliability in high-stress, real-time operational settings.
• Actively identify and address cross-team technical opportunities and challenges.
