• Attend client and design team meetings, providing clear technical input
• Review technical output and support junior engineers and technicians
• Help maintain strong technical standards across project delivery
• Build trusted client relationships and support repeat business
• Incorporate sustainability, low‑carbon design and compliance into engineering decisions

What we are looking for

• Degree, HNC or HND in Mechanical Engineering, Building Services Engineering or a related discipline
• Ideally 4 to 6 years+ mechanical building services design experience
• Consultancy background with experience delivering coordinated mechanical design projects
• Strong hands‑on experience with calculations, schematics, layouts, specifications and design reviews

• Confidence dealing directly with clients and multidisciplinary design teams
• Experience supporting or mentoring junior engineers
• Interest in low‑carbon, renewable, BREEAM and net‑zero design
