Senior/Staff Electrical Systems Engineer

Our reactor's Instrumentation and Controls system is fundamentally an electrical system: sensors and transmitters, signal conditioning and I/O, instrument power and distribution, actuators and their drive electronics, control panels, and every cable and interface between them. This role owns the electrical requirements for that system and the evidence that it work, what each element must do, how it can fail, how we prove its performance, and how we defend those claims to a regulator.

You'll work at the layer where control intent becomes hardware behavior: signal accuracy, response time, failure states, electrical interfaces, redundancy, power quality, and system integration. Your work establishes the technical baseline that controls software, testing, licensing, and plant operations rely on. This role carries technical authority over the I&C requirements baseline, ensuring every requirement is clear, traceable, and verifiable.

Roles & Responsibilities:

• Work with electrical system Responsible Engineers to create the requirement baseline: Capture regulatory, functional, performance, safety, and concept-of-operations requirements, decompose them to the component level, and make sure every one of them carries measurable, verifiable acceptance criteria. No requirement leaves your hands without a way to prove it was met.
• Own and maintain interface control documents: Define and hold the hardware and software ICDs across every electrical system — signal definitions, ranges, timing, protocols, power and grounding, failure and default states — so that subsystem teams can build independently and still integrate.
• Own the I&C Design FMEA: Drive failure mode identification to completion, score severity, occurrence, and detection, and calculate risk priority numbers. Then make the analysis matter: build and drive the test plan that burns down the high-RPN modes, and track them to closure.
• Create the design validation and qualification plan: Define what qualification means for each I&C system, then partner with the test team to specify test setups, test cases, instrumentation, and pass/fail criteria — and support execution on the bench and in the testbed when it counts.
• Support the licensing case: Translate system design into the documentation a regulator reads: work with the licensing and systems engineering teams to produce and defend the I&C content in our safety analysis and design documents, and keep requirements traceability intact from regulation down to test result.
• Own site certification for non-listed components: Where the electrical system uses components without an existing UL listing, own the path to acceptance — field evaluation with an NRTL, the supporting technical documentation, and the relationship with the authority having jurisdiction.
• Support grid interconnection: Partner with the mission and deployment teams as the electrical technical lead when we interconnect at a site: interpret utility interconnection requirements, support interconnection studies and applications, and translate what the utility demands — protection and relaying, power quality, ride-through and trip settings, metering, disconnection and islanding behavior — into requirements our design actually has to meet.
• Own the electrical requirements conversation with customers: Work directly with customers to capture their load requirements — profiles, critical and non-critical loads, power quality expectations, redundancy and availability — along with their user interface and data requirements, and bring those back as specified, verifiable requirements rather than expectations captured in an email thread.
• Bridge controls software and physical hardware: Work with the software team to ensure that the hardware design meets the control requirements and that the software can effectively control the hardware.
