What You’ll Do

This isn’t your average grad job — you’ll be at the heart of real projects shaping the energy systems of the future.

You’ll gain hands-on experience in:

• Mechanical Design & Engineering: Assist with the design, review, and optimisation of mechanical systems for renewable energy, hydrogen, and industrial energy projects.
• Project Development Support: Contribute to feasibility studies, technical specifications, and tender documentation.
• Equipment & Systems Analysis: Support the selection, sizing, and assessment of mechanical equipment (e.g. piping, rotating equipment, structures, thermal systems).
• Site Exposure: Participate in site inspections, construction support, commissioning, and operational performance reviews.
• Hydrogen & Industrial Systems: Gain exposure to hydrogen production facilities, balance-of-plant systems, and process infrastructure.
• Collaboration: Work closely with electrical, civil, environmental, and project development teams across multiple geographies.
• Safety & Compliance: Learn and apply relevant South African and international mechanical, pressure, and HSE standards.

What You’ll Bring

• A Bachelor’s degree in Mechanical Engineering (or in the final stages of completing one).
• A genuine interest in renewable energy, sustainability, and industrial infrastructure.
• Strong analytical thinking and problem-solving skills.
• Curiosity, initiative, and a willingness to learn in a fast-paced environment.
• Good communication skills and a collaborative mindset — because great engineering is never done in isolation.

What You’ll Get

• A strong foundation and launchpad into the renewable energy and green hydrogen sector.
• Mentorship from experienced engineers and exposure to international projects.
• Hands-on learning across project development, construction, and operations.
• A supportive, innovative, and people-focused environment where your contribution matters.
• A competitive graduate salary and the opportunity to work on projects that make a real-world impact.
