Mechanical Design Engineer Shape Low-Carbon Solutions from Concept to Technical Delivery
Are you a Mechanical Design Engineer ready to move beyond conceptual work and into real-world delivery? We're offering an opportunity to take a hands-on role in designing renewable heat systems and energy-efficient HVAC solutions with a clear focus on RIBA Stages 3 and 4.

You'll join a growing decarbonisation team tackling complex engineering challenges in retrofit and new-build environments, with projects that support the UK's transition to net zero.

As a key part of a multidisciplinary team, you'll focus on developing robust technical designs and turning strategic intent into build-ready solutions.

This includes:

Leading mechanical design development through RIBA Stage 3 (Spatial Coordination) and Stage 4 (Technical Design) for energy centres, plant rooms, and heat network systems.
Engineering low-carbon systems: commercial heat pumps, high-efficiency HVAC, and integrated control strategies.
Creating and coordinating detailed 3D models using AutoCAD, REVIT, Navisworks, and thermal simulation tools (e.g. IES VE, Hysopt, EnergyPRO).
Producing engineering calculations, specifications, and design risk assessments that hold up under real-world scrutiny.
Working closely with electrical, civil, structural, and energy specialists to deliver fully coordinated and practical solutions.
Supporting non-invasive surveys and interpreting site data to feed into technical design.

About you

Solid understanding of mechanical building services and HVAC system design principles.
Proven experience working through RIBA 3 and 4 stages, ideally on low-carbon or retrofit projects.
Knowledge of British Standards, Building Regulations, and HVAC legislation.
Skilled in AutoCAD, REVIT, Microsoft Office; familiarity with design simulation tools (IES, Hysopt, etc.).
Strong awareness of CDM and health & safety in design.
Ability to communicate clearly, contribute to reports, and lead sections of technical documentation.

Why join

Focus on technical design and engineering delivery not just early-stage consultancy.
Join a team with real capability in energy transition, heat decarbonisation, and sustainable infrastructure.
Work on projects that matter - low-carbon buildings, energy centres, district heat, and smart controls.
Be supported in your career growth with access to training, certifications, and mentoring.
