Staff High Voltage Electrical Engineer (EPC / Substation Design) * California
The Company ⚡
This is one of the fastest-scaling organisations operating in the advanced energy and electrification space, building infrastructure that sits directly behind the transition to large-scale electrified industry.
At its core, the business is developing and operating high-capacity electrical systems that support energy-intensive industrial processes and grid-connected expansion. The engineering environment is fast-moving, highly technical, and backed by significant long-term investment into infrastructure and capability.
The work includes large substation and transmission-level systems (69kV-345kV), integrated into complex industrial facilities where reliability, uptime, and scale are critical to success.
This is not a maintenance environment. It's a build-and-scale engineering function with real ownership over how high-voltage systems are designed, delivered, and improved over time.
The Role
This is a senior-level high-voltage EPC engineering role sitting at the centre of design, analysis, and delivery.
You would be responsible for:
* Leading end-to-end design of high-voltage AC systems for industrial substations (69kV-345kV)
* Developing protection & control schemes, grounding systems, and single-line diagrams
* Owning technical input into grid interconnection and utility coordination discussions
* Performing fault studies, load flow analysis, and system performance modelling
* Reviewing complex vendor packages, RFIs, and construction-stage design queries
* Acting as Engineer of Record on critical high-voltage infrastructure packages
You won't be working in isolation - this role sits directly between engineering, construction, and commissioning, meaning your designs are actively built, tested, and energised in the field.
Why This Role Exists 📈
This hire is part of a wider expansion of the organisation's high-voltage EPC capability as project volume increases and infrastructure complexity grows.
The business is scaling its internal engineering function to support a growing pipeline of grid-connected industrial developments and long-term electrification projects.
Put simply: more work, more complexity, and a need for deeper in-house technical ownership.
The Candidate
Must Have:
* Degree in Electrical Engineering (ABET accredited or equivalent)
* Active Professional Engineer (PE) licence in California, or eligibility via reciprocity
* Strong background in high-voltage substation or transmission-level design
* Hands-on experience with protection, grounding, and power system studies
* Familiarity with tools such as PSSE, PSLF, PSCAD, ASPEN OneLiner (or equivalent)
Nice to Have:
* EPC environment or large-scale infrastructure project delivery experience
* Field exposure (construction, commissioning, or troubleshooting HV systems)
* Utility or ISO/RTO interface experience
* Exposure to HVDC or advanced grid integration systems
The Opportunity 🔧
This is a chance to step into a technically significant role where your work directly impacts real-world high-voltage infrastructure being designed, built, and energised at scale.
You'll gain exposure across the full project life cycle - from early design through to commissioning - within an environment that is actively building out its engineering capability rather than maintaining legacy systems.
For the right person, this offers a rare combination of technical depth, project scale, and genuine influence over how systems are engineered.
