And when you join us, you'll be a part of this genuinely collaborative environment, where everyone's voice is valued and treated equally. We're passionate about what we do, but we don't take ourselves too seriously. Simply put, this a great place to be. So, when it comes to your life outside of work, ask us about our flexible and remote working policies designed to help you get the most out of life. Additionally, if you've taken time away from your career and are ready to return, we offer a range of supportive opportunities designed to help you confidently step back into the workplace and continue your professional journey.
Are you ready to take the next step in a role where your expertise makes a real impact? As a Senior Systems Engineer in our Advanced Engineering Delivery & Consultancy (AEDC) practice, you'll be a key contributor on programmes that protect the UK and secure its future. You'll work on complex, high‑profile projects that require strong systems thinking, technical leadership, and the confidence to influence decisions in demanding environments.
In this role, you'll collaborate closely with world‑class clients and multi‑disciplinary teams, shaping system solutions and guiding less experienced engineers. You'll be trusted to take ownership of significant work packages and to help deliver programmes based in some of the UK's most secure and strategically critical locations – including Aldermaston, Barrow‑in‑Furness, Faslane and Devonport.
In this role, you'll experience real breadth across the full system lifecycle — from shaping early concepts through to integration and delivery – working across land, sea, air, and Critical National Infrastructure (CNI) domains. You'll operate comfortably in complex environments where no two challenges are the same. As a Senior Systems Engineer, you'll lead technical workstreams and small teams, guiding engineering decisions and ensuring that system components align with the wider solution. You'll play an active role in mission engineering, requirements engineering and architecting activities applying Model‑Based Systems Engineering (MBSE) methods and using contemporary digital approaches to support design, analysis and verification, and helping to set good practice for others to follow.
You'll work closely with stakeholders at every level, from engineers to senior leaders, influencing outcomes and shaping solutions that make a real difference. And because these programmes are critical to national security, you'll know that your contribution has impact far beyond the office.
Your role
- Lead the application of systems engineering processes, such as ISO 15288:2023, across the full engineering lifecycle.
- Utilise MBSE approaches and tools (e.g. Sparx EA, Cameo) and apply modelling languages and architecture frameworks including UML/SysML, ArchiMate, TOGAF, and MODAF.
- Conduct requirements engineering and ensure clear linkage to verification and validation activities.
- Select, tailor, and implement appropriate engineering lifecycles for projects.
- Integrate complex systems across a range of platforms, such as military and civilian platforms (including submarines, aircraft, ships, and vehicles), as well as advanced power and energy systems.
- Manage projects and teams within various development methodologies.
- Demonstrate an understanding of the MOD's'acquisition framework and apply Knowledge in Defence (KiD) appropriately.
- Build trusted relationships using strong interpersonal skills and effectively communicate complex subjects to non-engineers and senior stakeholders.
