• Major capital programme within a leading UK higher education campus involving phased redevelopment and expansion works

• Hyperscale data centre programme with mission–critical electrical infrastructure and high resilience requirements

This is a highly design–led contractor environment where engineers are trusted with real ownership, technical responsibility, and direct client engagement.

Key Responsibilities

• Lead Mechanical design delivery across multiple concurrent major projects

• Manage design development from early concept through detailed design and construction stages (RIBA 1–5)

• Provide technical leadership, mentoring.

• Coordinate with internal disciplines, clients, and external consultants

• Support delivery of mission–critical and large–scale infrastructure environments

• Ensure compliance with relevant UK regulations, standards, and client requirements

• Contribute to design optimisation, value engineering, and technical innovation

• Circa 70,000 basic salary

• Car allowance

• All travel expenses covered

• Strong forward workload (2+ years secured pipeline)

• Exposure to landmark UK developments and major infrastructure schemes

• Long–term progression within a growing and stable design team

About You

• Mechanical Engineer with strong building services design experience

• Proven experience delivering projects through RIBA Stages 1–5

• Background in consultancy or contractor design environment

• Experience working on large–scale commercial, infrastructure, or mission–critical projects

• Data centre experience highly advantageous

• Strong leadership, coordination, and stakeholder management skills

Why Apply?

This is an opportunity to join a stable and expanding design function delivering some of the UK's most technically challenging and high–value projects, including a significant presence in the data centre and major infrastructure sector. You'll have autonomy, responsibility, and the chance to influence design delivery at a senior level across a secure long–term pipeline.
