We are looking for an experienced EC&I Designer who can demonstrate:
- Proven experience designing EC&I systems, ideally within a nuclear or other highly regulated environment.
- Extensive experience producing EC&I drawings and technical design documentation.
- Strong AutoCAD experience.
- Practical knowledge and understanding of technical design development.
- A sound understanding of engineering design and safety principles.
- Experience working within structured quality, health & safety and engineering procedures.
- Good working knowledge of relevant engineering software and computer applications.
- The ability to work independently while contributing effectively to a wider multidisciplinary engineering team.
Essential Qualification
- HNC in EC&I Engineering or a related engineering discipline.
Why This Opportunity?
This is more than a conventional EC&I design position. You’ll be contributing to a high-profile UK defence infrastructure programme, working on engineering systems that will support the future operational capability of the UK’s submarine fleet.
With £45 per hour, predominantly remote working and only 1-2 days per week required in Abingdon or Warrington, this role offers an excellent combination of technical challenge, programme significance and flexibility.
