Principle Engineer - Protection & Control (P&C) London, Leeds, South - Hybrid Permanent Full Time

Salary Competitive (DOE) & Flexible Benefits

This role involves designing and overseeing the implementation of protection schemes, control systems, and related equipment to ensure the safe and reliable operation of power networks, substations, and Transmission & Distribution electrical infrastructure.

This position requires technical expertise and vast experience working in Transmission and Distribution sector for protection & control and Substation Automation system/SCADA design (from 11kV up to 400kV).

As Principal you will lead the design and specification of protection and control systems for electrical substations, powerplants, and transmission/distribution networks.

• Develop protection settings, relay PSL files, coordination studies, including fault detection and isolation strategies.
• Lead on TSO/DNO standards & specifications with respect to P&C Design & Calculations, as well as overall Substation Design Works. He/She should ensure compliance with relevant national and international standards (e.g., IEC, BS, IEEE) in protection system design.
• Design, implement and maintain SCADA/communication systems for a variety of clients in sectors including utilities, oil and gas, manufacturing, industrial automation and various other communication networks.
• Configure and optimize network infrastructure & communication protocols such as IEC 61850;
  Distributed Network Protocol (DNP
  3);
  Parallel Redundancy Protocol (PRP);
  Precision Time Protocol (PTP);
  Network Time Protocol (NTP);
  Simplified Network Time Protocol (NTP);
  Modbus, OPC, Profibus, etc for seamless integration with field devices, including RTUs, PLCs, IEDs, etc, also ensure stable connectivity between SCADA centres & remote sites, and configure secure VPNs & remote access protocols to allow for safe, off‑site monitoring and control.
• Understand client requirements & produce network architecture philosophy diagram, IED telecommunication diagram, SCADA & Telecommunications Panel design, Network IP allocation, I/O Schedules, Cable & Core schedules, etc.
• Assist with the setup and commissioning of SCADA systems at client sites, troubleshoot field devices and network communication issues, perform preventive and corrective maintenance on SCADA infrastructure and associated hardware.
• Efficiently design/develop the SCADA/communication systems (e.g., Ignition, Siemens WinCC, GE iFIX, etc) to ensure real‑time data acquisition and control for critical infrastructure.
• Provide remote support for troubleshooting SCADA system and network issues, ensuring minimal downtime and swift resolution of critical incidents.
• Conduct system upgrades, testing, and validation for new features, components, and patches.
• Implement cybersecurity measures to safeguard SCADA systems against emerging threats.
• Collaborate with cross‑functional teams to ensure smooth integration and deployment of SCADA systems.
• Provide technical leadership and mentoring to junior engineers in the design, analysis, and commissioning of protection systems.

• Extensive experience in electrical protection and control system design, Substation Automation and SCADA system typically 12‑15 years, with a proven track record of delivering complex projects within the power sector.
• Candidate should have vast experience in crafting Single Line Diagrams, AC & DC Schematic Drawings, Panel General Arrangements, Panel Wiring Diagrams, Switchgear Termination/interconnection drawings, Block Cable Diagrams/Schedules, and performing cable specification/sizing calculations, battery sizing calculations, CT/VT sizing, multicore sizing, Relays CORTEC/specifications.
• Candidate should have experience in testing & commissioning of P&C, SCADA/Communication/SAS panels. Should be able to identify potential risks and failures within protection and SCADA systems and propose mitigation strategies.
• Candidate should have good knowledge & experience working with AutoCAD.
• Candidate should have good knowledge of substation primary design and substation equipment/switch gear specifications. He/She should…
