Requirements Engineer, Systems Engineer

Requirements Engineer

Location: Berkshire (Hybrid)

Type: Contract (Outside IR35)

Security Clearance: SC clearance required

We are working with a well-established engineering and project delivery organisation operating within the UK nuclear sector. They support major programmes across the full project lifecycle, delivering engineering, design, consultancy, refurbishment, installation, and decommissioning services within highly regulated and high-hazard environments. With a strong reputation for technical expertise and collaborative project delivery, they work across some of the UK’s most complex nuclear sites and infrastructure programmes.

This position would suit a Mechanical Engineer or EC&I Engineer who has practical experience undertaking requirements capture and requirements management activities within complex engineering environments. This is not a traditional Systems Engineering or “stereotypical” Requirements Engineering role.

The successful candidate will contribute to complex engineering programmes across high-hazard and highly regulated environments, supporting requirements capture, integration, verification, and validation activities.

Attendance on site will be required a minimum of 2 days per fortnight, although more frequent site attendance may be required depending on project needs.

• Plan and execute engineering tasks to agreed objectives, ensuring delivery against cost, quality, and schedule requirements.
• Support collaborative project delivery and contribute to wider programme objectives.
• Promote high standards across safety, security, quality, and environmental performance.
• Mentor and support junior engineers where appropriate.

• Capture, analyse, and translate stakeholder requirements into technical specifications.
• Develop and manage requirements using DOORS.
• Produce use cases, context diagrams, and other engineering artefacts.
• Support requirements derivation, architecture development, and modelling activities where required.
• Undertake verification and validation activities, including development of test cases and test plans.
• Support integration activities across multiple engineering disciplines and sub-systems.
• Contribute to lifecycle planning using engineering best practice methodologies.
• Support internal and external project reviews through written reports and presentations.
• Promote continuous improvement of engineering processes and practices.

• Significant commercial and government sector experience within engineering and requirements capture activities.
• Background as a Mechanical Engineer or EC&I Engineer.
• Experience writing use cases and applying modelling techniques.
• Experience in system design, specification, and interface management.
• Understanding of engineering lifecycle processes.
• Knowledge of the UK nuclear industry and regulated environments.
• Strong stakeholder engagement and communication skills.
• Ability to interpret and evaluate technical data and documentation.
• Competent in Microsoft Office applications.
• Familiarity with ISO 9001, ISO 14001, and ISO 45001 standards.

• Degree qualified in Engineering or a related discipline, or equivalent practical experience.
• Professional membership with a relevant engineering institution is desirable.
• Health & Safety qualification such as IOSH Managing Safely is advantageous.
