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.
