Senior Power System Secondary Engineer

Design Review & Verification

• Lead the review and verification of all secondary design deliverables — including Single Line Diagrams (SLDs), Protection & Metering Diagrams (PMDs), Block Logic Diagrams (BLDs), AC/DC schematics, and LV System Design Documents — for HV substations and renewable plants.
  
• Verify protection and control philosophies, including relay settings, selectivity analyses, and coordination studies (short-circuit calculations, CT/VT sizing) prepared by consultants and EPC contractors.
  
• Review and approve interlocking schemes, bay-level logic, and station-level automation across switchgear, transformers, feeders, and renewable energy plant interfaces.
  

Substation Automation & SCADA

• Approve substation automation and SCADA architectures, ensuring correct implementation of IED logic, signal lists, and interlocking schemes at bay and station levels.
  
• Oversee the integration and configuration of communication protocols — IEC 61850 (GOOSE/SV/MMS), IEC 60870-5-104, and DNP3 — governing data flow between Plant Power Controllers (PPC/EMS), substations, and utility control centers.
  
• Review IED configurations, substation HMI displays, and historian / data management architectures for completeness and compliance.
  
• Telecommunications & Cybersecurity
  
• Review and validate communication and telecommunication architectures, including managed network design (VLANs, PRP/HSR redundancy), cybersecurity policies (IEC 62351 / NERC-CIP aligned), and tele-protection performance requirements.
  
• Ensure robust cyber-physical security practices are embedded throughout the secondary system design lifecycle.
  

​

Standards, Compliance & Grid Code Adherence

• Ensure strict adherence to international standards and grid codes (IEC, IEEE/ANSI) by performing technical audits and vetting technical submissions to Transmission / Distribution System Operators (TSO/DSO).
  
• Manage technical interfaces and coordinate between EPC contractors, engineering consultants, OEMs, and the grid operator to ensure a coherent and optimized secondary systems design.
  

Requirements

Education

Bachelor’s or Master’s degree in Electrical Engineering, Power Systems, or a closely related field.

Professional Engineering registration (PE / CEng or equivalent) is an advantage.

Experience

8+ years of engineering experience with a demonstrable focus on substation secondary systems design and delivery.

Significant experience in a developer, owner’s engineer, or utility role with direct responsibility for managing and challenging EPC contractor deliverables.

Proven track record on grid-connected utility-scale renewable energy projects (Solar PV, Wind) and/or Battery Energy Storage Systems (BESS).

Experience working across the full project lifecycle from FEED and detailed design through to FAT, SAT, and commercial operation.
