As a Senior Mission & Complex Systems Engineer / Consultant within our Operational Systems team, you’ll play a key role in delivering high-quality engineering and consultancy services across complex, mission-critical and operational systems.

Working across defence and other high-consequence sectors, you’ll help our customers define, integrate, assure, sustain and evolve complex capabilities, translating operational challenges and technical evidence into practical, robust solutions.

You’ll take ownership of defined technical activities and work packages, working independently and alongside multidisciplinary teams across Systems Engineering, Cyber, operational analysis and other specialist areas. Partnering with Project Managers and technical leads, you’ll help shape delivery approaches, manage technical risks and dependencies, and ensure outputs are delivered to the right quality, timescale and budget.

Beyond project delivery, you’ll have the opportunity to contribute to bids, innovation and capability development, share your expertise with colleagues, and help develop reusable methods and approaches that strengthen our Operational Systems capability.

You’ll be an experienced engineer or consultant with a strong background in complex operational or engineered systems, comfortable taking ownership of technical work and working independently within your area of expertise.

You’ll bring experience across areas such as systems thinking, requirements and architecture, systems integration, verification and validation, test and evaluation, operational assurance, and through-life capability management. Experience of mission-enabling systems, including command, control, communications or information systems, would be particularly relevant.

You’ll be confident translating complex technical challenges into clear, practical and evidence-based recommendations, communicating effectively with both technical and non-technical audiences. You’ll use sound professional judgement, recognise when specialist input or escalation is needed, and be comfortable working across multidisciplinary teams and with customer stakeholders.

Alongside your technical expertise, you’ll be able to build strong customer relationships, contribute to bids and proposals, and identify opportunities to support wider customer needs. You’ll have a relevant engineering, scientific or technical qualification, or equivalent professional experience, with a track record of successfully delivering technical work with a high level of independence and accountability.

Professional registration such as IEng or CEng would be advantageous, although we’re equally keen to hear from those working towards appropriate registration.
