Early-Career Construction Engineers – Nuclear Pathway

Assystem is one of the world’s leading engineering organisations, delivering major low carbon infrastructure across the UK and internationally. With almost 8000 specialists, we support flagship programmes such as Hinkley Point C, Sizewell C and the next-generation Small Modular Reactors. Our teams work at the heart of complex construction delivery, engineering assurance and large scale project execution.

The UK is entering the Golden Age of Nuclear, and early-career engineers have a unique chance to shape it. Experience gained at Hinkley Point C becomes a direct pathway into future programmes like Sizewell C, SMRs, fusion and advanced reactor projects. If you’re early in your career and currently working in construction, utilities, heavy industry, energy, water, defence or similar, your skills transfer naturally into nuclear. You’ll gain exposure you simply won’t find elsewhere: major project scale, technical depth and long-term progression. You’ll also benefit from competitive pay, strong pension contributions, flexible hours, professional fee support and future opportunities across Assystem’s expanding UK portfolio.

Please note – we’re unable to offer visa sponsorship for this role, so applicants must have full right to work in the UK.

We are recruiting early-career construction-focused engineers looking to build their future in nuclear new build. These roles support the delivery of Mechanical, Electrical and HVAC systems on Hinkley Point C, one of Europe’s most complex construction programmes. You will work directly on active construction areas, supporting installation oversight, coordination, inspections, documentation, progress tracking, site queries and project delivery tasks. This is hands-on engineering with real influence, not a desk-only position. These roles are site-based, five days a week at Hinkley Point C. If you are not local, you must be willing to relocate to the Bridgwater or Somerset area.

We are looking for early-career engineers who have:

• NVQ Level 4, HND or Degree in construction, mechanical or electrical engineering
• Understanding of CDM regulations and how they apply on site
• Experience working in construction or other heavy industrial environments
• Ability to read drawings or interpret technical documentation
• Awareness of installation methods, sequencing or construction processes
• Confidence working with contractors on live construction activities
• Comfortable using digital tools for reporting and coordination
• Willing to relocate if not within commuting distance of HPC

Due to project security requirements, unfortunately, visa sponsorship is not available for this position.

Benefits include:

• Flexible working hours
• Pension scheme (8% company / 4% personal)
• 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 & 3× 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.
