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.
The Role:
* 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
The Person:
* 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
We are an equal opportunities company and welcome applications from all suitable candidates.
