Lead Software Engineer

Southampton (Hybrid, 4 days per week in the office)
Are you a senior software engineer looking to take end to end technical leadership of a complex, real-time distributed platform that integrates directly with mission-critical hardware used in security and critical infrastructure environments?
This is a principal-level technical role within a specialist engineering business developing a real-world platform that ingests, processes and surfaces live telemetry from radiation detection systems deployed in highly sensitive locations. The software underpins real-time monitoring, alerting and operational decision-making, where performance, reliability and security are non-negotiable.
You will lead the technical direction of a TypeScript-based microservices platform, remaining hands-on across backend services while also owning a large Angular enterprise application used by customers in the field. Working closely with a capable onshore team and an established offshore function, you will shape architecture, standards and delivery across the full software lifecycle.
