Permanent

Hybrid

Salary depending on exprience up to circa £65,000 with some flexibility

Are you an experienced Mechanical Design Engineer looking to take the lead on complex, cutting-edge engineering projects?

We're supporting a pioneering engineering organisation developing next-generation turbomachinery and high-temperature process systems that are redefining industrial performance.

They are now seeking a Principal Mechanical Design Engineer to lead major design workstreams and influence the mechanical architecture of state-of-the-art machinery.

The Opportunity

In this senior position, you'll own the mechanical design of advanced rotating equipment and high-temperature static structures. You'll define design requirements, drive design standards, and help shape engineering processes for a new era of industrial machinery.

This role offers genuine technical challenge, autonomy, and the chance to make a meaningful impact on the future of high-performance engineering.

Key Responsibilities

• Lead mechanical design activities for complex turbomachinery components
• Produce detailed product definition using Siemens NX & Teamcenter PLM
• Carry out and oversee 1D calculations, 2D analysis, and 3D FEA (thermal, structural, modal, fatigue)
• Review and approve design work from other engineers
• Define subsystem requirements and ensure robust mechanical architecture
• Improve engineering tools, design methods, and best practices
• Present updates to senior stakeholders and mentor junior engineers
• Ensure compliance with BS, ASME, API, ISO and other relevant standards

What You'll Bring

• 7+ years' experience in mechanical design
• Strong background in turbomachinery and/or high-temperature structural components
• Expertise in high-temperature alloys (nickel-based, stainless steels, etc.)
• Thermo-mechanical design experience, including fatigue and life assessment
• First-principles approach with strong analytical capability
• Proficiency in Siemens NX & Teamcenter PLM
• Strong communication and technical reporting skills

Beneficial:

• Degree in Mechanical/Aerospace Engineering (higher degree preferred)
• Chartered Engineer or working towards it
• Experience in fast-paced R&D or developing emerging technologies
• Python or similar coding for workflow automation

Why Join?

You'll be part of a forward-thinking engineering business driving innovation in advanced machinery. Expect:

1. Complex, meaningful engineering challenges
2. Influence over system architecture and design standards
3. A collaborative, international engineering environment
4. Opportunity to help shape next-generation, cutting edge industrial technology
