Senior Mechanical Design Engineer

Lead Diverse, High-Profile Projects from Concept to Completion

Are you a creative and technically-minded Mechanical Engineer ready to take the next step in your career? We are looking for a Senior Mechanical Design Engineer to act as a project lead, mentor our growing team, and drive sustainable, innovative design across a diverse portfolio.

This isn't just a design role; it's a leadership opportunity. You will be the technical authority for the mechanical discipline, steering complex projects in sectors from healthcare and critical systems to commercial and residential. If you are on the path to Chartership and want to lead, mentor, and innovate, this role is for a you.

What You'll Be Doing: Your Impact

• Lead Project Delivery: You will take full ownership of the mechanical design process across all RIBA stages (1-5), acting as the primary discipline lead on multiple concurrent projects.

• Technical Excellence: Produce and sign-off on detailed calculations, specifications, and reports for all core mechanical systems, including HVAC, LTHW/CHW, domestic water, and compressed air systems.

• Drive Sustainable Innovation: Champion energy-efficient design, ensuring solutions are cost-effective and meet the highest sustainability goals (Part L, BREEAM, and Net Zero Carbon).

• Team Leadership & Mentorship: You will be a cornerstone of our team, managing the workload of graduate and intermediate engineers, reviewing their designs, and actively mentoring their technical and professional development.

• Multidisciplinary Coordination: Act as the key mechanical contact, coordinating designs flawlessly in a BIM environment with electrical, public health, structural, and architectural teams.

• Client Engagement: Confidently attend and lead design team meetings, progress reviews, and client presentations, articulating and justifying your design decisions.

What You'll Bring to the Table

Essential Experience & Qualifications:

• Proven Experience: A 5-8+ year track record in a mechanical building services design role.

• Project Portfolio: Demonstrable experience delivering medium to large-scale projects (e.g., MEP values of £5m-£100m+).

• Sector Versatility: A strong background in several of our key sectors: commercial offices, residential, healthcare, pharmaceutical, data centres, or education.

• Technical Expertise: Deep knowledge of CIBSE guidelines, UK Building Regulations (especially Part L), BSRIA standards, and sustainability benchmarks.

• Qualifications: A Degree or HNC/HND in Mechanical Engineering or Building Services Engineering.

• Chartership: You must either be Chartered (CEng) or actively working on a structured path to achieving it with CIBSE or IMechE.

• Software Proficiency: High-level skills in core design software, including Revit MEP, AutoCAD, and IES VE / Hevacomp.

Bonus Points (Highly Desirable):

• Formal membership with CIBSE or IMechE.

• Specific experience in designing Net Zero Carbon buildings, Passivhaus, or advanced renewable technologies (ASHPs, GSHPs, Heat Networks).

Why This Opportunity?

• A "True Lead" Role: This is a position with genuine autonomy to lead projects and make key technical decisions.

• Exceptional Project Variety: You will not be siloed. Gain invaluable experience across challenging sectors, including high-spec critical systems and healthcare.

• Career & Chartership Support: We provide a clear and funded path to Chartership and continuous professional development to help you reach Principal level.

• Build a Team: This role is perfect for someone who is passionate about mentoring and wants to play a key part in developing the next generation of engineers.

• Influence & Innovate: You'll be a key voice in our design strategy, contributing to innovation and best practice in a collaborative team.
