You'll have access to a variety of qualifications pathways ranging from GCSE/A-Level equivalent all the way up to master's degree, depending on your role, your previous skills and your experience.

Visa & relocation
As a result of the changes to the UK immigration rules which came into effect on 1 January 2021, the Ministry of Defence will only offer sponsorship for a skilled worker visa under the points-based system, where a role has been deemed to be business critical. This role does not meet that category, and we will not sponsor a visa. It is therefore NOT open to applications from those who will require sponsorship under the points-based system.
Should you apply for this role and be found to require sponsorship, your application will be rejected and any provisional offer of employment withdrawn.
The role
Looking for an engineering role where your judgement, leadership and technical knowledge will genuinely matter? Join the HMNB Clyde Design Authority team as a Principal Design Engineer and help shape the policies, standards, designs and engineering evidence that keep vital infrastructure safe and effective. You will tackle varied technical challenges, influence projects from early concept through to operation and life extension, and support the development of the next generation of engineering professionals. It is a role with real responsibility, plenty of variety and the opportunity to make a lasting professional impact.
What you'll do
- Act as the Design Authority's Subject Matter Expert and Intelligent Customer, providing authoritative engineering direction within your Engineering discipline and demonstrated area of competence.
- Lead the specification, authorship, development, assessment, acceptance, approval, maintenance and management of engineering designs, substantiation, policies, standards, methodologies, guidance, processes and template.
- Translate legislation, regulatory expectations, Safety Management System requirements, recognised standards and relevant good practice into clear, proportionate and practical engineering requirements.
- Ensure infrastructure designs, modifications and supporting engineering evidence meet applicable nuclear, explosive and non-nuclear safety, performance, integrity and operational requirements.
- Ensure engineering substantiation provides robust evidence to support Safety Case claims and arguments and demonstrates that risks have been reduced as low as reasonably practicable.
- Maintain alignment between design intent, Safety Functional Requirements, Operational Functional Requirements and the substantiation of relevant structures, systems and components.
- Define appropriate evidence expectations and acceptance criteria, enabling delivery teams to demonstrate compliance with approved engineering policies, standards and safety requirements.
- Assess engineering designs, modifications, departures, concessions and alternative standards, making recommendations or providing approval where formally delegated and within your demonstrated competence.
- Ensure hazard analysis, source data, commissioning requirements, examination, inspection, maintenance and testing requirements, operating conditions and operational constraints are clearly identified and appropriately substantiated.
- Provide technical direction throughout the engineering lifecycle, including concept development, design, procurement, manufacture, construction, commissioning, operation, maintenance, modification and life extension.
- Lead or support independent technical and peer reviews, ensuring that the scope, reviewers, evidence, findings and responses are suitable and proportionate.
- Develop, assess and maintain through-life examination, inspection, maintenance and testing schedules, procedures and associated engineering requirements.
- Review engineering and maintenance results to confirm that infrastructure continues to meet its design intent, safety requirements and operational constraints.
- Support Periodic Safety Review activity by defining engineering standards and evidence expectations, advising on technical findings and contributing to the effective management of shortfalls.
- Work with Safety Case, compliance, assurance and Authorisation Condition specialists to maintain alignment between engineering requirements, Safety Case expectations and organisational arrangements.
- Provide engineering expertise to compliance assessments, audits, inspections, interventions and corrective-action activities.
- Monitor recurring engineering shortfalls, departures, lessons and implementation concerns, identifying trends and recommending improvements to policies, standards and assurance arrangements.
- Present engineering designs, substantiation, policies and technical matters to relevant safety committees, authorisation groups, working groups, inspections and professional forums.
- Build effective relationships with MOD departments, Design Authorities, Authorisees, regulators, programme and project teams, private-sector organisations, consultants and contractors.
- Promote a strong nuclear safety, security and engineering culture, encouraging adherence to approved arrangements, constructive challenge, learning from experience and proportionate decision-making.
- Apply appropriate engineering governance and assurance arrangements to authorised, licensed, non-authorised and wider Estate infrastructure activities.
