My client is seeking a passionate and driven Geothermal Systems Engineer to join their small, dynamic team dedicated to designing low‑carbon geo‑energy structures adopting our USP, the Hiperpile. This role focuses on the development of Hiperenergy solutions and the integration of Hiper systems into a variety of applications including residential and commercial buildings, heat networks, data centres as well as large‑scale infrastructure projects.

Our work covers the disciplines of deep foundation and MEP design, installation and maintenance so a systems‑thinking mindset and a willingness to engage with multidisciplinary challenges are essential. This position is ideal for an Engineer with 3–4 years of experience in geotechnical or energy engineering, and a strong interest in sustainability and innovation.

Role Overview

The Geothermal Systems Engineer will be responsible for designing, modelling, and optimizing geothermal heating and cooling systems for residential, commercial, and industrial applications. You will collaborate with cross‑functional teams to deliver high‑performance solutions that meet technical, environmental, and regulatory standards.

Key Responsibilities

• Design and engineer geothermal systems, including ground‑source heat pump configurations, loop fields, and distribution systems.
• Perform site assessments, feasibility studies, and energy modelling using industry‑standard tools.
• Create detailed technical drawings, specifications, and documentation for installations.
• Conduct thermal response testing and analyse geological and hydrogeological data.
• Work closely with project managers, drilling teams, and construction partners throughout project life cycles.
• Ensure all designs comply with relevant codes, regulations, and sustainability objectives.
• Troubleshoot system performance issues and provide technical support during commissioning.
• Contribute to R&D initiatives to enhance system efficiency and innovation.

Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering, Environmental Engineering, Geothermal Engineering, or a related field.
• Experience in geothermal system design or HVAC engineering (GSHP experience highly desirable).
• Proficiency with design and simulation software (e.g., LoopLink, GLHEPro, AutoCAD, Revit, EnergyPlus).
• Strong understanding of thermodynamics, heat transfer, and fluid mechanics.
• Familiarity with drilling processes, ground‑loop installation methods, and hydrogeology.
• Excellent problem‑solving skills and the ability to communicate complex technical concepts clearly.
• Professional Engineering (PE) licence or willingness to pursue one (preferred).

What They Offer

• Competitive salary and benefits package
• Opportunities for professional development and certification
• A collaborative, environmentally driven workplace
