Senior Instrumentation and Control Engineer
Ref: 2025-4104
A global environmental engineering consultancy is continuing to grow its smart infrastructure and automation capability and is now seeking a Senior Instrumentation and Control Engineer to take a leading role in the delivery of major water and wastewater projects.
This organisation is widely respected for delivering complex, high-impact infrastructure that protects communities, strengthens resilience, and supports long-term sustainability. They operate at the forefront of water sector innovation, designing facilities that integrate advanced automation, digital monitoring, and intelligent control systems. Their teams work on long-term, technically challenging programmes rather than short, transactional projects, offering real ownership, continuity, and professional credibility.
This role is suited to a senior engineer who wants more than technical delivery alone. You will be a visible technical leader, trusted advisor to clients, and a driving force behind how complex treatment facilities are designed, automated, and ultimately operated.
The opportunity
You will lead instrumentation and control design on medium to large-scale water and wastewater projects, shaping system architecture from early concept through to construction and commissioning. You will guide clients, influence design direction, mentor engineers, and ensure technical excellence across all I and C deliverables.
Your impact will include:
-
Leading I and C design teams on major treatment, pumping, and network infrastructure projects
-
Defining scopes of work, budgets, and delivery strategies for complex control systems
-
Designing PLC, SCADA, and industrial communication networks
-
Developing control philosophies, P&IDs, system architectures, and technical standards
-
Overseeing selection and specification of instrumentation, panels, telemetry, and fiber and radio networks
-
Managing technical quality, programme, and cost across the instrumentation discipline
-
Acting as a senior technical interface with clients, including workshops, design reviews, and standards development
-
Mentoring and developing engineers and designers, building long-term team capability
-
Supporting construction, commissioning, and operational integration
This is a role where your technical judgement will directly influence how facilities are built, automated, and optimized.
Why this role stands out
-
Senior ownership of technically complex, high-profile projects
-
The chance to shape automation strategy rather than just deliver drawings
-
Long-term programmes that allow deep technical involvement and client influence
-
A business that invests heavily in people, leadership development, and technical excellence
-
Clear progression toward principal and technical leadership pathways
-
Work that has visible, real-world impact on communities and the environment
What they are looking for
-
Degree qualified in Electrical, Instrumentation and Control, Mechanical, or Chemical Engineering
-
Typically 10 to 15 years’ experience delivering instrumentation and control systems in water, wastewater, or similar industrial environments
-
Professional Engineer registration
-
Recognised expertise across industrial automation, instrumentation selection, and communication networks
-
Strong background developing P&IDs, control schematics, and control strategies
-
Proven experience leading multidisciplinary teams and managing technical delivery
-
Confidence engaging directly with clients, leading workshops, and influencing design decisions
-
Strong communication skills with the presence to operate at senior project and stakeholder level
A master’s degree and experience with MicroStation or AutoCAD are beneficial but not essential.
