The Opportunity
The global shift toward a low‑carbon future is accelerating, and the UK’s energy landscape is transforming at pace. Stantec is helping lead this transition - supporting communities to produce, distribute and consume energy more sustainably. If you’re passionate about shaping a cleaner, more resilient energy system, this is your chance to join our industry‑leading Energy & Resources business and make a meaningful impact.
Following continued project wins and new client partnerships, we are expanding our Waste & Generation team and are looking to recruit a Senior Mechanical Engineer. You’ll be based across our Redditch or Newcastle upon Tyne offices, working on some of the most exciting and technically diverse projects in the sector.
The Role
As a Senior Mechanical Engineer, you will contribute to a wide portfolio of energy projects, including Energy‑from‑Waste (EfW) facilities, District Heating networks, Gasification and Hydrogen schemes, and Biogas/Anaerobic Digestion plants. You’ll work across the full project lifecycle—from early optioneering and feasibility through to detailed design and installation.
Your Responsibilities Will Include
- Conducting site surveys and technical investigations
- Developing mechanical designs, specifications and project‑wide engineering solutions
- Supporting the production of drawings, 3D models, P&IDs, schedules and reports
- Preparing specifications and scoping documents for construction packages
- Reviewing vendor designs and monitoring progress throughout delivery
You’ll collaborate closely with multidisciplinary teams, clients and contractors to ensure designs are robust, safe and aligned with project objectives.
Your Impact
Your work will directly influence how energy is generated, recovered and utilised across the UK. By developing efficient mechanical systems and supporting the delivery of innovative technologies—from EfW to hydrogen and biogas—you will help clients reduce carbon emissions, improve performance and transition to more sustainable solutions.
You will play a key role in shaping project outcomes, ensuring that mechanical designs are technically sound, constructible and future‑ready. Your expertise will support safer, more efficient facilities and contribute to the long‑term resilience of the UK’s energy infrastructure.
