Frazer-Nash is a values-driven and forward-thinking engineering, systems and technology consultancy. We help organisations deliver innovative engineering and technology solutions that make lives safe, secure, sustainable and affordable.
Our engineering specialists support clients across the full lifecycle of assets in a range of sectors, including nuclear/low-carbon energy, transport, defence and the process industries. We combine deep technical understanding with practical consultancy skills to help clients understand, design, improve and assure complex engineering systems.
We are growing and are looking for engineers who can bring strong technical judgement, clear communication, and a practical approach to solving complex client problems. Your work will help to:
PostDoc or Industry?
Finishing a doctorate is a big deal. Pursuing a path into academia through a PostDoc position is explored by some, but many look to apply their skills in an industrial context and gain commercial skills in parallel. If you are looking for this opportunity, either as a recent graduate or with some experience, then Frazer-Nash could be for you!
As a high-tech engineering consultancy, we value the additional skills and experience that doctorate graduates bring to our business. For us, the value you bring comes through a combination of specialist knowledge, a robust understanding of engineering fundamentals from undergraduate teaching, experience of presenting at conferences, and ability to engage with a range of stakeholders to solve complex problems. Within our Fluids, Physics and Systems Performance area, over 25% of your potential colleagues and line managers have completed PhDs, DPhils or EngD themselves, and are therefore readily equipped to help you make the most of your skills and experience to build your career.
Why Join Frazer-Nash?
Our engineers are empowered to take ownership of their work, build lasting client relationships, and develop specialist expertise, while working as part of supportive, collaborative teams. We value technical excellence, curiosity, and the ability to turn complex analysis into clear, actionable insight.
Why this Role?
As a Fluids and Thermal Engineering Consultant, you will apply your understanding of fluid mechanics and heat transfer to help clients understand system behaviour, assess performance, reduce risk, and make better engineering decisions. You will contribute across the consultancy lifecycle, from technical analysis and modelling through to client engagement, writing bids, project delivery and capability development.
Variety of work
Our consultants typically work on several projects at once, ranging from short, focused studies to long-term programmes of support. Expect exposure to different industries, clients, technologies, and technical challenges, helping you broaden your capability while deepening your expertise.
Teamwork and collaboration
You will work as part of a supportive group, collaborating with specialists from multiple disciplines. You will be proactive in developing your own skills, seeking advice when needed, and sharing your experience to support the development of colleagues.
Taking the lead
As you develop, you will manage technical work packages, plan and deliver work to time, cost, and quality, and engage directly with clients and internal stakeholders. As your experience grows, you will have opportunities to lead teams, guide colleagues, and shape technical approaches.
Growing capability
Supporting bids and proposals, developing new service offerings, contributing to technical communities, and representing Frazer-Nash in client discussions, conferences, or seminars.

We value professional accreditation, including Chartered Engineer and Fellow status, and provide mentoring and support to help employees achieve this recognition of their work.
