Senior EICA Design Engineer
Water & Wastewater Infrastructure
If you enjoy owning complex EICA design and being trusted as the technical expert, this one’s for you.
This is a Senior EICA Design Engineer role where your expertise genuinely matters. You’ll be leading electrical, instrumentation, control and automation design across critical water and wastewater infrastructure projects — shaping solutions that are safe, efficient, sustainable and built to last.
You won’t just be producing designs. You’ll be guiding decisions, influencing standards, mentoring engineers and working directly with clients to solve real engineering problems. If you like being the person others turn to for clarity and direction, you’ll feel right at home here.
The Role — Where You’ll Make an Impact
As a Senior EICA Design Engineer, you’ll take technical ownership of EICA design from early concept through to detailed design and delivery, working as part of a multi-disciplinary engineering team.
Your day-to-day will include:
* Leading the production of EICA design deliverables across water and wastewater projects
* Producing clear, high-quality drawings, specifications, schedules, calculations and control philosophies
* Reviewing supplier and subcontractor designs, identifying risks, optimising solutions and ensuring compliance
* Supporting client design reviews, technical meetings and workshops to secure approvals
* Acting as a technical authority, clearly explaining complex EICA concepts to non-specialists
* Managing design risk, ensuring safety, operability, maintainability and whole-life cost are considered
* Mentoring and supporting junior engineers, helping develop capability within the team
* Contributing to tender reviews, cost assessments and technical input for bids
This is a Senior EICA Design Engineer role with influence — both technically and culturally.
The Kind of Engineer Who Thrives Here
You’ll do particularly well if you:
* Enjoy being accountable for technical decisions
* Like leading design rather than just contributing small pieces
* Take pride in producing clear, robust, well-thought-through designs
* Want to help shape how EICA engineering is delivered, not just follow existing templates
What You’ll Bring
* Strong experience delivering EICA design for water and wastewater infrastructure
* Degree (or equivalent) in Electrical, Control, Automation or a related discipline
* Solid understanding of:
* Electrical distribution and LV design
* MCCs and ICA systems
* Proven ability to produce high-quality EICA deliverables including:
* Schematics and layouts
* Calculations and load assessments
* Experience using AutoCAD, BIM 360 and relevant water-sector design tools
* Strong knowledge of CDM regulations and safe-by-design principles
Working Environment & Location
* A blend of office-based design, site visits and hybrid working
* Exposure to projects across London and the South of England
* A professional environment that values technical excellence and practical engineering
Why This Senior EICA Design Engineer Role Stands Out
* Technical leadership without stepping away from hands-on engineering
* Real influence over design quality, standards and delivery approach
* Opportunity to mentor and shape the next generation of EICA engineer
