Location: Portsmouth, UK

An opportunity has arisen for a Systems Engineer to join a leading Defence & Space organisation, working on Military Satellite Communications (Milsatcom). The successful candidate will be part of a team of Lead Systems Engineers and Architects, contributing to diversified and future‑looking programmes.

The Systems Engineer will play a key role in defining system architectures for upcoming tender opportunities with the UK MOD (Skynet Enduring Capability) and other Milsatcom programmes-covering the space, control, and ground segments. This is a chance to be directly involved in the next wave of technologies shaping secure satellite communications.

Key Contributions

  • Capture and define requirements from stakeholder needs through to sub-systems, ensuring traceability and verification.
  • Support Verification, Validation & Test (VV&T) activities.
  • Lead ground system architectural design definition and trade-off analysis.
  • Collaborate with Engineering Leads and Partners in integrated working groups to define segment and sub-system architectures.
  • Provide technical inputs for proposals and act as Solution Lead during customer and internal governance reviews.
  • Offer technical support to bidding teams and contribute to project planning, scheduling, and cost activities.
  • Keep stakeholders informed on progress and resolve technical challenges.

Candidate Profile

  • Degree (or equivalent) in Electronic Engineering, Computer Science, Telecommunications, or related discipline.
  • Experience in the design, integration, and deployment of end-to-end digital telecommunications systems (Milsatcom experience desirable), covering space, control, and ground segments.
  • Familiarity with Waterfall and Agile methodologies.
  • Expertise in defining solutions within an Architectural Framework using Model-Based Systems Engineering (MBSE) tools (EA experience a plus).
  • Strong customer and partner engagement skills.
  • Working knowledge of satellite platforms and payloads, satellite control, mission control, and network control.
  • Excellent presentation and writing skills.

Why This Role Matters

This is more than just a job-it's an opportunity to engineer history. The Systems Engineer will be part of programmes that set the standard for secure communications, with direct impact on national defence and the evolution of space-based networks.
