Are you an experienced software engineer looking to take principal-level ownership of a complex, real-world distributed system used across security and critical infrastructure environments? This is a senior technical role within a specialist engineering business building software that directly integrates with radiation detection hardware deployed in highly sensitive settings. The platform powers real-time monitoring, telemetry, alerting and operational decision-making, supporting customers where reliability, security and accuracy are critical.

You will take ownership of a distributed, microservices-based platform, shaping its architecture and technical direction while remaining hands‑on with development. Working closely with a small but highly capable onshore team and an established offshore engineering function, you will have genuine influence over how the system evolves and how features are delivered. This is a fantastic opportunity for an engineer who enjoys deep technical challenges, architectural responsibility and working on systems that have tangible, real‑world impact.

• Ownership of a Linux-based, microservices-driven software platform
• Hands‑on development across core services and system components
• Defining and evolving secure, scalable system architecture
• Working closely with and guiding offshore engineering teams
• Contributing to strong testing, CI/CD and DevSecOps practices

• Strong experience with distributed systems and microservices architectures
• Comfortable operating in Linux-heavy, security-constrained environments
• Hands‑on engineer with architectural ownership experience
• Strong testing mindset with CI/CD and DevSecOps exposure
• Confident influencing technical direction within small, senior teams
