About the Role

We’re seeking an experienced PLC Control Systems Engineer (5-10 years) to design, program, test and commission industrial control systems across power solutions projects. Including diesel generator controls, switch gear/ATS/AMF panels, load sharing/synchronisation, and associated HMI/SCADA interfaces.

The role spans the full project lifecycle (FDS/DDS, coding, FAT/SAT, on-site commissioning), working closely with electrical design, project managers, and clients to deliver robust, safe, and maintainable systems that meet industry standards.

Key Responsibilities

Design & Development

Produce and own control system deliverables:
User Requirements (URS), FDS, DDS/SDS, I/O lists, Cause & Effect, alarms, and test plans.
Develop PLC/HMI/SCADA applications to internal coding standards and client specifications.
Configure and integrate generator controllers (Deep Sea Electronics (DSE), Com Ap, Woodward), synchronising and load‑sharing schemes, ATS/AMF logic, and black‑start/priority management.
Interface PLCs with protection relays, meters, breakers, UPS, and BMS/EMS systems.
Collaborate with electrical design for wiring schematics (e.g., EPLAN/AutoCAD Electrical) and panel build liaison.

Testing & Commissioning

Lead FAT/SAT, I/O checks, loop testing, simulation, and site commissioning.
Troubleshoot PLC, HMI/SCADA, and communications networks; implement robust fixes and design improvements.
Produce handover packs, as‑built software, change logs, and training for end users (O&M).

Documentation, Quality & Compliance

Maintain version control, change management, and code libraries (e.g., Git-based workflows).
Ensure compliance with functional safety and electrical standards where applicable (e.g., IEC 60204-1, SIL principles/IEC 61511), PUWER, and Machinery Directive/UKCA.
Contribute to RAMS for site works; uphold ISO 9001 quality procedures and good engineering practice.

OT Networking & Cybersecurity

Design and commission industrial Ethernet networks (managed switches, VLANs, NAT, routing).
Implement and document secure architectures and segmentation, harden PLC/HMI/SCADA assets, and apply password/backup policies and access controls in line with best practices.
Configure and troubleshoot common industrial protocols:
Modbus TCP/RTU, Profinet, Profibus, Ether Net/IP, OPC UA; (nice to have: IEC 61850, DNP3).

Continuous Improvement & Support

Mentor junior engineers, contribute to coding standards, reusable function blocks, and templates.
Provide remote and on‑site support, root‑cause analysis, and preventive maintenance recommendations.
Suggest design enhancements for reliability, maintainability, and lifecycle cost reduction.

- Allen Bradley, Siemens TIA Portal (SCL/ladder), WinCC/Unified;
  Rockwell Studio 5000 (Ladder/Structured Text), Factory Talk View.
- Optional:
  Schneider Eco Struxure, Mitsubishi GX Works, Beckhoff TwinCAT, AVEVA/Wonderware, Ignition.
- Must have written system code from conception / from design.

Generator & Power Integration

DSE/Com Ap/Woodward controller integration, breaker control, load management, protection interfaces.
Familiarity with UPS systems, power meters, and protection relays.

Networks & Protocols

Layer‑2/3 concepts, VLANs, NAT, routing, industrial firewalls;
Modbus, Profinet, Profibus, Ether Net/IP, OPC UA.

Electrical & Safety

Read/mark up schematics, panel layouts, and cable schedules.
Awareness of IEC 60204-1, functional safety (SIL concepts), BS 7671 principles, PUWER; RAMS.

Qualifications & Certifications (Desired)

Degree/HND in Electrical, Electronic, Control/Automation, or Mechatronics Engineering (or equivalent experience).
ECS/CSCS or safety passports.
