Senior EC&I Engineer - Nuclear Power & Energy Projects

Location: Hybrid | Warrington, Knutsford, Newcastle, Gloucester or Bristol

Emplyment Type: Permanent

Are you an experienced EC&I Engineer ready to step into a senior role with real impact?

Our client is seeking a Senior Electrical, Control & Instrumentation (EC&I) Engineer to join their Energy business - supporting major UK nuclear and renewable projects that are shaping the nation’s clean energy future.
This is your opportunity to play a pivotal role in delivering safe, innovative engineering solutions that support the UK’s Net Zero carbon target.

Why This Role?

You’ll join a forward-thinking team that’s supporting the UK’s nuclear fleet through a period of transformation - from life extension and defueling projects to the development of next-generation small modular reactors (SMRs). Alongside this, you’ll have opportunities to work across renewable energy, hydrogen production, and high-energy industrial facilities such as data centres.
Our client’s culture is centred on integrity, inclusion, and collaboration - where people are empowered to grow their careers, share ideas, and deliver work that makes a tangible difference.

The Challenge

As a Senior EC&I Engineer, you’ll lead the development and delivery of EC&I design and engineering solutions across the full project lifecycle - from bid generation and concept design through to detailed design, installation, and commissioning. You’ll take ownership of technical workstreams, mentor junior engineers, and act as a key interface with clients and stakeholders across the UK.

Your responsibilities will include:

• Leading the development of EC&I designs and solutions across concept, detailed design, installation, and commissioning stages.
• Preparing technical documentation, specifications, and design justifications for safety-critical systems.
• Supporting systems integration, testing, and validation of PLC, SCADA, and simulator systems.
• Applying a systems engineering approach to new architectures and supporting requirements capture.
• Ensuring compliance with regulatory standards, including nuclear safety and cybersecurity requirements.
• Managing and checking deliverables from junior engineers to maintain accuracy and quality.
• Providing mentorship and technical guidance to developing engineers.
• Interfacing with clients, regulators, and stakeholders on technical and project matters.
• Supporting project planning, cost estimating, and risk management activities.
• Producing high-quality technical reports and contributing to continuous improvement.
• Building and maintaining effective relationships with clients, partners, and peers to ensure successful project delivery.

This is a highly collaborative role, where you’ll work closely with Principal Engineers, Engineering Managers, and Operations Managers to ensure that every project meets its time, cost, and quality objectives.

What You’ll Bring

You’ll have a strong technical foundation and proven experience delivering EC&I engineering solutions within the nuclear industry or another highly regulated sector. You’ll bring:

• A degree (BEng/BSc/MEng/MSc) or equivalent in EC&I or a related discipline.
• Chartered or near-Chartered Engineer status (support provided where required).
• Sound understanding of EC&I design principles, tools, and relevant standards (BS, IEC, IEEE - particularly IEC 61508, 61511, 61513, 61226, and ONR SAPs/TAGs).
• Experience of the full C&I system lifecycle, including specification, design, assessment, verification, testing, commissioning, and maintenance.
• Knowledge of high-integrity hardware or software-based control systems.
• Awareness of systems engineering and conceptual design.
• Excellent problem-solving ability and strong communication skills, with the confidence to articulate information across all levels.
• A commitment to continuous professional development and technical excellence.

If you’re ready to take ownership of complex engineering challenges and support the UK’s transition to a low-carbon future, this is your next step.
