The Position: Systems Modelling & Simulation Engineer

We’re looking for an engineer with a passion for simulation and systems thinking to join our growing team. This role sits at the intersection of numerical simulation, acausal modelling, and MBSE, and offers the chance to apply advanced engineering methods to real-world challenges on a nationally significant programme.

Some of the main responsibilities of the Systems Modelling & Simulation Engineer

will include:

• Developing and extending simulation libraries to support complex, multi-physics analysis.
• Connecting MBSE models with ANSYS (via ModelCenter or similar tools) to create integrated system-level simulations.
• Carrying out thermal, structural, and neutronic analysis using established numerical methods.
• Helping to couple simulations across domains and exploring ways to speed them up with reduced-order modelling.
• Writing small code routines to automate repetitive tasks and streamline workflows.
• Preparing clear reports and documentation to support decision making.
• Working closely with colleagues from different engineering backgrounds to share knowledge and deliver consistent, high-quality results.

In this role, you will have the chance to support one of the most rare and exciting nuclear engineering programmes in the UK. This is more than a single role – it’s a chance to be part of a team shaping how multiphysics, modelling and systems engineering come together on a nationally significant project.

Preferred Profile:

Alongside a commitment to our values of Care & Compassion, Performance, Team Spirit, and Inclusiveness, we are looking for individuals who can bring the following:

• A degree in engineering (or equivalent experience).
• Strong background in numerical simulation, ideally with ANSYS.
• Experience using acausal modelling languages such as Modelica, Simscape, Dymola or Amesim.
• Familiarity with MBSE approaches and tools (SysML, Capella, Cameo, or similar).
• Detailed knowledge of core engineering principles across multiple domains.
• Someone who can explain their work clearly, write up findings well, and collaborate easily with others.
• Experience creating or applying reduced-order models would be an advantage.
• An interest in multi-domain co-simulation or digital twins.

This position can also be based in various locations across the UK due to our UK-wide project portfolio and offices in Warrington, Gloucestershire, Northumberland, Hampshire, Cardiff or Bristol.

Please note that visa sponsorship is not guaranteed and is assessed on a case-by-case basis, depending on role criticality and project needs. Many of our UK projects require high-level security clearance, meaning we can often only consider candidates with an existing, indefinite right to work in the UK. Exceptionally, we may consider visa sponsorship for applicants with niche experience aligned to our core work (e.g. EPR/nuclear new build).

Remuneration & Benefits:

We offer a competitive salary tailored to your experience and background. Whether you're earlier in your career or bring more senior-level expertise, we encourage you to apply if this role aligns with your skills, or if you're open to discussing other opportunities within this discipline.

We also offer a benefits package, both standard and enhanced, which is designed to support your wellbeing, development, and financial future, including:

• 25 Days Annual Leave + Bank Holidays, with the ability to swap bank holidays for cultural or religious celebrations
• Matched Pension Scheme
• Enhanced Maternity, Paternity, Adoption and Neonatal Care Leave
• Employee Referral Scheme
• Private Medical & Dental Insurance
• Electric Vehicle Scheme
• Cycle to Work Scheme
• Training & Development, including additional qualifications and accreditations relevant to your role
• Travel Insurance – for both business and personal travel
• Employee Assistance Programme

Why join us?

At Vulcain Engineering, we offer more than just a job, we offer a rewarding career with endless opportunities for growth and development. You'll be part of a talented team of professionals working on exciting and meaningful projects and making a real impact to the nuclear industry.
