Principal Design Engineer

Join a leading clean energy company developing innovative hydrogen-based technologies to support the global shift toward net-zero emissions. As part of a growing team focused on unique energy storage systems, this role offers the chance to work on impactful technology that’s moving into commercial deployment.

The team is now recruiting for a Principal Design Engineer with a strong background in high-temperature chemical reactor design. This is a senior-level opportunity within a multidisciplinary team driving the next generation of clean energy solutions. You’ll take ownership of component and system design, helping bring cutting-edge technology from concept to real-world application.

Key Responsibilities

Generate and manage design requirements, identifying potential technical risks early.

Deliver robust mechanical and reactor system designs from concept through to proof-of-principle.

Produce high-quality 3D CAD models and detailed engineering drawings for components, assemblies, test rigs, and fixtures.

Lead design reviews and oversee engineering change management processes.

Provide technical guidance and mentorship to colleagues, contributing to team development.

Act as a subject matter expert in design, development, materials, manufacturing methods, and testing.

Drive innovation and contribute to the development of valuable intellectual property.

Ensure design compliance with international standards and internal best practices.

Lead and coordinate cross-functional activities to ensure timely project delivery.
Requirements:

You’ll bring a blend of technical leadership, hands-on design expertise, and a passion for clean energy technology. You thrive in a fast-paced environment where innovation, collaboration, and continuous improvement are core to success.

Degree-level qualification in mechanical, chemical, or a related engineering discipline.

Significant experience in mechanical and/or reactor systems design.

Strong capability with 3D CAD (e.g. SolidWorks, Creo) and engineering drawing creation.

Confident in applying design fundamentals through hand calculations and FE analysis.

Familiar with GD&T, failure modes, and root cause analysis.

Strong understanding of design verification and relevant test methods.

Able to work independently, plan effectively, and meet project deadlines.

Effective communicator with excellent documentation and collaboration skills.
Desirable:

Experience in high-temperature chemical reactor or heat exchanger design.

Familiarity with ANSYS Workbench and simulation techniques.

Exposure to thermodynamics, CFD, electronics, or materials science.

Understanding of robust design, statistical methods, and systems engineering.

Practical prototyping or mechanical assembly experience

How Many Materials Science Tools Do You Need to Know to Get a Materials Science Job?

If you’re navigating the materials science job market, it can feel like the list of tools, techniques and platforms you should learn grows every week. One job advert mentions electron microscopy, another mentions X-ray diffraction, yet another wants experience with thermal analysis, spectroscopy, simulation software, statistical packages, manufacturing QA systems and more. With so many specialised methods and instruments, it’s easy to feel overwhelmed — and to start thinking you need to know everything just to be considered. Here’s the honest truth most materials science hiring managers won’t tell you directly: 👉 They don’t hire you because you know every piece of equipment or software. They hire you because you can use the tools you do know to answer real questions, make reliable measurements and communicate results clearly. Tools are essential — no question — but they are secondary to problem-solving ability, scientific reasoning and experimental rigour. So the real question is: how many materials science tools do you actually need to know to get a job? The precise number depends on the role you want, but for most job seekers the answer is far fewer than you think. This article breaks down what employers really value, which tools are core, which are role-specific, and how to focus your learning so your CV and interviews stand out for the right reasons.

What Hiring Managers Look for First in Materials Science Job Applications (UK Guide)

Materials science is a broad, interdisciplinary field that spans academia, industry, research, engineering and manufacturing. Whether you’re applying for roles in R&D, process development, quality assurance, failure analysis, nanomaterials or product scale-up, hiring managers make key decisions within the first few seconds of scanning your application. In competitive job markets, simply listing skills or qualifications isn’t enough. Hiring managers are looking for signals of relevance, technical depth, problem-solving capability and real-world impact — and they expect those signals to be clear right from the top of your CV or portfolio. This guide breaks down exactly what hiring managers typically look for first in materials science applications, why they look for it, and how you can optimise your CV, cover letter and portfolio so your application stands out and gets past the first filter.

The Skills Gap in Materials Science Jobs: What Universities Aren’t Teaching

Materials science sits at the heart of innovation — from sustainable energy and advanced manufacturing to aerospace, electronics, healthcare and beyond. It is an interdisciplinary field combining physics, chemistry, engineering and applied science to design and improve materials that power modern technology. Despite the clear strategic importance of materials science, employers across the UK report persistent challenges hiring graduates who are truly job-ready. Organisations need professionals who can contribute immediately to research, development, manufacturing, quality control and product scale-up — yet many recent graduates struggle to bridge the gap between academic preparation and workplace demands. This gap is not caused by a lack of intelligence or enthusiasm. It is a growing skills gap between what universities teach and what real materials science jobs require. This article explores the materials science skills gap in depth: what universities teach well, what they often miss, why the gap exists, what employers want, and how aspiring professionals can bridge the divide to build successful careers in this vital UK industry.
