Assystem is a global engineering and project delivery company focused on accelerating the energy transition worldwide. Our 7,500 Switchers combine deep engineering heritage with digital innovation to deliver complex, safety-critical programmes. In the UK, we are supporting landmark projects including Hinkley Point C, Sizewell C, and the next generation of Small Modular Reactors. Our teams work at the front end of new nuclear, shaping systems, defining requirements, and turning early concepts into deliverable, licensable solutions.
Joining Assystem means becoming part of one of the three largest nuclear engineering companies in the world. You will work in an environment that values technical thinking, structured problem solving, and long-term career development. Our teams influence projects from the earliest design stages, not just execution. You will be supported through continuous learning, internal mobility, and the opportunity to work across fusion, modular nuclear, and major UK infrastructure programmes.
We are looking for EC&I Engineers across all levels, from those with just 3 years experience, up to principal level. These roles can be based across the UK, with offices in Bristol, Warrington, Blackburn, Derby, and Sunderland, supported by hybrid working arrangements.
You will shape EC&I and control system concepts from early requirements through detailed design and delivery. Your future team works across full lifecycle projects, translating stakeholder needs into robust, compliant control architectures.
- Define control and EC&I system requirements from stakeholder engagement
- Develop front-end and concept-level control system architectures
- Produce control philosophies, functional requirements, and system descriptions
- Structure end-to-end control systems across PLCs, HMIs, networks, instrumentation
- Apply vendor-agnostic PLC and DCS design principles
- Support verification, validation, FAT, SAT, and design assurance activities
- Collaborate with mechanical, process, safety, and human factors engineers
- Apply nuclear-grade configuration control and lifecycle governance
Though previous nuclear experience would be great, please note it is not essential. We actively encourage applications from engineers in other highly regulated sectors who are keen to transition into nuclear and fusion environments. We also recognise that it's unlikely you will meet every requirement listed below, but if you have 6-7 of these skills, I would still like to hear from you.
- Experience in highly regulated industries such as nuclear, pharma, aerospace, oil and gas
- Systems engineering mindset with requirements capture experience
- Front-end engineering or concept design project exposure
- Broad PLC experience with vendor-agnostic approach
- Understanding of DCS, HMI, networks, and instrumentation layers
- Functional safety experience applying relevant sector standards
- Lifecycle project experience from concept through implementation
- Awareness of OT cybersecurity in control system environments
- Some commissioning exposure beneficial but not essential
This role is ideal for engineers who enjoy thinking, structuring, and defining complex control systems rather than purely executing specifications. You will influence designs from a blank sheet of paper and see them delivered on nationally significant programmes. If you bring strong systems thinking, experience from regulated environments, and the curiosity to learn, we would still love to hear from you.
Benefits include:
- Hybrid Working Opportunity
- Flexible working hours
- Market Leading Pension scheme (8% company contribution / 4% personal contribution)
- 25 days’ paid annual leave + bank holidays + option to buy or sell days
- Professional fees reimbursed
- Employee referral scheme
- Competitive Sick Pay - Support when you need it
- Income Protection & 3x Salary Death-in-Service Cover
- Free Digital Gym Access - Expert-led fitness classes
- 24/7 Employee Support Line - Mental health, financial & legal help
We are committed to equal treatment of candidates and promote, as well as foster all forms of diversity within our company. We believe that bringing together people with different backgrounds and perspectives is essential for creating innovative and impactful solutions. Skills, talent, and our people’s ability to dare are the only things that matter! Bring your unique contributions and help us shape the future.
