Senior Process Engineer- Thermal Systems

Senior Process Engineer – Thermal Systems

Astatine Limited is a specialised energy company founded by a highly experienced management team with a proven track record of entrepreneurial, commercial, and technical success. Astatine develop, design, construct, operate, fund (if required) and maintain multi-technology assets to enable an acceleration toward zero carbon for energy users across multiple sectors. The key values of our company are collaboration, innovation, urgency and integrity. Our core technologies include solar PV, battery energy storage, and heat pumps. This is a huge growth area forecast for the next 20 years, and the successful candidate will have the opportunity to upskill in these technologies, their applications and design considerations.

Due to continued growth and expansion, the company is now seeking to recruit a Senior Process Engineer.

Position Title: Join our team as a Senior Process Engineer and contribute to the end-to-end development of heating and cooling solutions for industrial and energy projects. This role spans concept to commissioning, with a focus on process design, mechanical design, equipment selection, and system integration with opportunities to work on innovative technologies like heat pumps and thermal storage. Experience with heat pump systems is a strong advantage.

The successful candidate will design complex high temperature heat pump systems, and integrate them to the client's process. This will need acute attention to detail, strong theoretical knowledge and practical experience. Supported by a team, you will need leadership skills to develop less experienced engineers and use resources effectively.
