Interview process: Likely 1 stage
A leading UK defence technology programme is looking for an SC-cleared Solution Architect to take a hands‑on technical leadership role, shaping a next‑generation C3I (Command, Control, Communications & Intelligence) interoperability reference architecture. This is a delivery‑focused position where you’ll set architectural direction, work closely with engineering teams, and help take early concepts/ PoCs into hardened, production‑grade patterns.
What you’ll be doing
* Leading the solution architecture across a C3I interoperability reference architecture
* Translating operational context into high‑level designs for engineering delivery
* Turning prototypes/PoCs into reusable architecture patterns and reference services
* Providing technical assurance: architecture decisions, design reviews, governance
* Driving DevSecOps ways of working (CI/CD, automation, IaC) for secure delivery
* Working closely with technical/operational stakeholders to align outcomes
* Mentoring engineers and junior architects; acting as technical steward/task lead
What we’re looking for
* Proven Solution Architecture experience on complex, mission‑critical / regulated programmes
* Strong secure design background (e.g., zero trust, identity, secure connectivity, cross‑domain considerations, data exchange controls)
* Comfortable moving between strategy and deep technical detail (incl. reviews/walkthroughs)
* Exposure to Defence / NATO approaches for C3I interoperability (nice to have)
* Tools/frameworks: Jira, Confluence, Visio; MoDAF beneficial
* Modern engineering patterns beneficial: APIs, microservices, event streaming, cloud‑native, containerisation, service mesh
To apply: Send your CV and confirm SC status, availability, and ability to travel to Portsmouth 1‑2x/month.
