Principal Operability and Crewing Engineer 

Design ships that are ready for the missions of tomorrow.

Navantia UK is hiring a Principal Operability and Crewing Engineer to shape how operability, automation and digital capability are engineered into complex naval and government vessels from day one. You’ll turn operational concepts (CONOPS) into practical, testable requirements that reduce workload, optimise roles, and credibly enable reduced-crewing and uncrewed concepts.

What you’ll do

• Lead operability and crewing/operator strategy across multiple ship design programmes.
• Develop CONOPS and run operational vignette workshops to stress-test concepts and technology choices.
• Define user-centred, mission-focused requirements that shape layout, accessibility, maintainability, workflow, human factors, and automation/digital systems.
• Develop and champion crew reduction/elimination concepts through human–machine integration and emerging digital technologies.
• Work closely with designers, suppliers, operators and stakeholders to embed operator solutions early and gain buy-in.
• Contribute to trade studies and cost/capability analyses so operator impact is visible in key decisions.
• Support safety and regulatory compliance, contributing to hazard identification and risk-based approaches for novel technologies.
• Represent Navantia UK with customers and cross-functional working groups, and mentor developing engineers.

What you’ll bring

• Significant experience in naval operations and/or naval ship design, with a focus on systems, operability and crewing.
• Experience developing crewing models and workload assessments, with a working knowledge of automation and digital technologies.
• Ability to influence across disciplines and translate operational needs into clear engineering requirements.
• Degree in Engineering (e.g., Systems, Mechanical, Marine, Human Factors) or equivalent operational experience.
• Eligibility for BPSS; the ability to obtain SC may be required depending on the programme.

Interested? Apply now, or message to discuss how you could shape operability and crewing for future Navantia UK platforms.
