Your new company is an established and growing building services contractor seeking a proactive, forward-thinking Mechanical Design Manager to lead its Offsite Design Team. This is an exceptional opportunity to join a dynamic business delivering innovative, large-scale engineering projects across the UK and Ireland. This company is well recognised for its design-and-build capability, typically developing projects from Stage 3 concept design through to completion. With extensive in-house prefabrication facilities, the organisation delivers modular plantrooms, skids, and offsite solutions for major residential, commercial, industrial, mixed-use and student accommodation developments.

Your new role is a hands-on, influential position offering involvement throughout the full project lifecycle, from early design and development through prefabrication, manufacturing and onsite installation. With fewer concurrent projects than traditional consultancy roles, you'll have the scope to prioritise quality, innovation, and technical excellence.

Key Responsibilities:

• Review and analyse employer requirements and tender documents.
• Produce schematics, calculations, specifications, and plant schedules.
• Work collaboratively with the internal design team in person and via email.
• Lead weekly design team meetings, setting project targets and ensuring high-quality delivery.
• Produce fabrication-ready drawings using fabCAD software.
• Coordinate mechanical services within plant areas, ensuring excellent buildability and integration with other disciplines.
• Support specification compliance, material selections, and weld standards.
• Mentor, guide, and support junior engineers in their development.
• Conduct site surveys and review installations (typically 1-2 days per month).
• Work closely with the Production team to align design output with workshop requirements.
• Support processes for recording design output data and understanding design-time costings.

What you'll need to succeed:

• Minimum 5 years' experience in a mechanical design role.
• Background in the commercial and industrial M&E sector.
• Organised, structured approach to workload.
• Analytical and detail-focused, with excellent problem-solving abilities.
• Strong communication skills and ability to lead technical discussions.
• Forward-thinking, proactive, and keen to improve systems and processes.

This position offers the rare chance to take ownership of innovative mechanical designs and see them progress from concept right through to fabrication and installation. You'll join a forward-thinking business invested in modern methods of construction, offsite innovation, and the professional growth of its people. For someone looking to lead a talented team, contribute to exciting engineering projects, and develop their career in a progressive environment, this role is an excellent next step.

Benefits:

• Cash Health Plan including Employee Assistance Programme.
