About the Company

A growing, independent mechanical design consultancy in Birmingham is looking for a Junior Mechanical Engineer to join its close-knit team. With a strong focus on low-carbon heating systems-particularly ground, air, and water source heat pumps-the company has built a reputation for producing detailed, whole-system designs from RIBA Stage 1 through to Stage 4.

Founded 5+ years ago by a former Director /specialist in commercial heat pump installers, the business started with a small team of three and has grown steadily to 12. They're a specialist consultancy that supports clients across a wide range of sectors, including:

Local authorities and councils

Universities and academic institutions

Contractors and design-build teams

They're known for their impartial, technology-agnostic approach and for offering something unique-supporting contractors all the way through to Stage 4 detailed design.

The Role

This is a hands-on design role, well-suited to a recent graduate or early-career engineer who is enthusiastic about sustainable technologies and keen to grow into project leadership.

You'll be involved in:

Designing ground source, air source, and water source heat pump systems

Supporting feasibility studies, heat loss surveys, and technical reporting

Using Revit to model mechanical systems (with support from experienced Revit users)

Training on IES for building performance simulation

Working across all project stages, including technical detailing for contractors

The team will guide you through every aspect of the job, with the aim of you confidently leading your own projects within a couple years.

Who They're Looking For

You'll need some prior industry experience-but curiosity, drive, and a practical mindset are essential. They look for candidates who bring something extra to the table, whether it's hands-on experience, creative problem-solving, or a quirk.

Ideal candidates will have:

A degree in Mechanical Engineering, Building Services, or a related field

Some form of practical, design, or engineering experience (even if from personal projects)

An interest in low-carbon and renewable heating technologies

A willingness to learn software tools like Revit and IES

The ability to work collaboratively in a diverse, multicultural team

Team Culture & Progression

The company fosters a welcoming and inclusive culture. The group includes engineers from a wide range of cultural backgrounds. They've only had one person leave the business since it was founded, reflecting a stable, supportive working environment.

This is a company that invests in people. Junior engineers are supported from day one, with the expectation that they'll become confident, all-round designers able to lead full projects in under two years.

You'll benefit from:

Daily mentorship and support from senior engineers

In-house training on industry tools and design methods

Early exposure to client work, site visits, and project ownership
