Full job description

Start your engineering career in the heat pump industry — no experience needed

We're looking for a bright, enthusiastic person who's good with computers and wants to learn a real technical trade. You don't need a heating background. You don't need a degree. You need to be quick on a PC, comfortable with numbers, and genuinely interested in learning how buildings are heated.

We'll teach you the rest.

Thermal Earth is one of the UK's longest-established heat pump specialists. We've completed over 3,500 ground source and air source installations, and we hold exclusive UK distribution rights for MasterTherm heat pump systems. Every home we heat is a home taken off fossil fuels — this is work that matters, in an industry that's growing fast.

What you'll actually be doing

You'll join our design office and learn, step by step, how a heat pump system is designed from scratch:

Heat loss calculations — working out exactly how much heat a building needs, room by room, using industry design software
System design — sizing heat pumps, underfloor heating, radiators, cylinders and buffer tanks to match the building
Technical drawings — producing schematics and layouts using our CAD tools
Design documentation — preparing the calculation packs and drawings that go to customers, installers and MCS certification
Supporting the wider team — working alongside senior design engineers, surveyors and project managers

You'll start by assisting on live projects, and progress to running your own designs as your knowledge builds.

What we're looking for

Essential:

Highly proficient with a PC — fast, confident, and quick to pick up new software. This is the single most important thing.
Strong grasp of everyday maths (you'll be working with numbers all day)
Attention to detail — a design error costs real money on site
Enthusiasm to learn, ask questions, and take on responsibility
Good written and verbal communication
Reliable, organised, and happy working as part of a small team

Nice to have (but genuinely not essential):

Any experience with CAD, Excel, or technical software
A-levels, BTEC, HNC or similar in maths, science, engineering or construction
A plumbing, heating or construction background
Full UK driving licence

We are open on background. School leaver, college leaver, graduate, or someone changing career from another trade — if you're sharp, keen and good on a computer, we want to hear from you.

What you'll get

£26,000 – £28,000 depending on experience
Full structured training — you'll be taught heat loss calculation, MCS design standards and system design from the ground up by engineers with decades of experience
Funded qualifications and a clear progression path from Junior Design Engineer to Design Engineer and beyond
Modern design office — we invest properly in our software and tools, including AI-assisted design systems. This isn't a paper-and-spreadsheet operation.
A stable, established employer — over 20 years in the industry, 3,500+ installations, and a full order book
Real purpose — every system you design cuts a household's carbon emissions for the next 25 years
28 days holiday including bank holidays
Free on-site parking
Company pension

Job details

Job type: Full-time, permanent
Hours: Monday to Friday, 8:30am – 5:00pm
Location: In person — Capel Hendre Industrial Estate, Ammanford SA18
Salary: £26,000 – £28,000 per year

How to apply

Apply through Indeed with your CV. A short covering note telling us why this role interests you will put you near the top of the pile — we read every one.

Thermal Earth Ltd is an equal opportunities employer. We welcome applications from all backgrounds. Welsh language skills are welcomed but not required.

Pay: £26,000.00-£28,000.00 per year
