Job Description:

Process Control Engineer (Hybrid Working)

Location: Portsmouth, Hampshire

An ambitious clean‑tech company is on a mission to make innovative energy storage the global standard. Enabling manufacturers, industrial processors, and heavy‑energy users to decarbonise at scale.

As part of their growth, they’re looking for a Process Control Engineer to take ownership of the control logic, instrumentation, and system architecture behind a next‑generation thermal energy storage steam generator. This is a pivotal opportunity to shape a first‑of‑its‑kind industrial product as it moves through design, prototype optimisation, and deployment into real customer sites.

As Process Controls Engineer, you will:

Become the internal authority on control sequences, fluids system control, and instrumentation — guiding the operability, safety, and performance of a breakthrough energy system. You’ll work across concept design, detailed engineering, prototype testing, and customer‑site integration.

This is a rare opportunity to:

  • Shape the full control architecture of a new industrial clean‑energy product
  • Influence how the system operates, responds, and manages faults across all conditions
  • Work closely with fluids, mechanical, and automation specialists to ensure seamless system behaviour
  • Play a hands‑on role in prototype optimisation and commissioning on real industrial sites

Key Responsibilities

  • Own the complete control logic and operating sequences for the thermal storage steam generator
  • Design high‑level control strategies to maximise system operability, safety, and performance
  • Specify instrumentation and controls hardware including valves, VFDs, pressure/temperature sensors, flow meters, and safety devices
  • Proven experience designing complete control sequences for complex or novel industrial systems
  • Strong knowledge of industrial fluids systems (valves, pumps, piping), ideally including steam processes, especially from a controls perspective
  • Strong knowledge of fluids instrumentation and control hardware

Why Join

You’ll be part of a mission‑driven, supportive team working toward a cleaner industrial future. Expect an informal, inclusive culture where every voice is valued. Flexible working, share options, and family‑friendly policies are all part of the offering.
