Permanent

Hybrid

Salary depending on experience up to circa £70,000 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 turbo machinery and high‑temperature process systems that are redefining industrial performance.

They are now seeking a Principal Mechanical Design Engineer to lead major design work streams 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 turbo machinery 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

Significant experience in mechanical design
Strong background in turbo machinery 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:

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