Permanent

Hybrid

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
• 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

• Strong background in turbomachinery and/or high‑temperature structural components
• 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:

• 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?

• Influence over system architecture and design standards
• A collaborative, international engineering environment
• Opportunity to help shape next‑generation, cutting edge industrial technology
