Staff Electrical Engineer

Rune•Mountain View, CA

6d•$170,000 - $200,000

About The Position

As Staff Electrical Engineer, NPI, you will lead the power electronics, distribution, and energy storage subsystems from concept through production release and field support across every RELIC configuration. You will produce the design packages, validation evidence, and engineering transfers needed at each development phase, work closely with mechanical, manufacturing, and reliability engineers, and establish electrical standards for the product line. Travel is up to 10%.

Requirements

Bachelor's degree in Electrical Engineering or equivalent industry experience.
At least 8 years designing electrical systems in energy storage, power conversion, grid-connected equipment, data-center power, or similarly demanding production hardware.
Demonstrated ownership of an electrical subsystem through a full development lifecycle, from requirements definition and concept through validation and production release.
Hands-on experience producing and releasing electrical design packages, including single-line diagrams, schematics, wiring diagrams, cable schedules, and panel layouts.
Direct experience with protection coordination and device selection, including short-circuit calculations, breaker and fuse sizing, and conductor and busbar ratings.
Working knowledge of battery energy storage design, including pack architecture, battery management, thermal runaway safety, and parallel-string behavior.
Hands-on experience with harness and interconnect design, grounding and bonding schemes, and connector selection for outdoor environments.
Direct experience with electrical commissioning and energization on live equipment, including factory and site acceptance testing (FAT/SAT) and stored-energy safety practices.
Comfort working on the floor alongside assembly technicians and in the field alongside installation crews.
Excellent communication skills, including the ability to hold a technical position with senior design engineers and drive cross-functional decisions to closure.

Responsibilities

Drive power electronics, distribution, and energy storage subsystems from concept through production release and field support for each product configuration.
Define subsystem engineering requirements from the product requirements document, assess technology availability, and complete preliminary risk assessments during concept development.
Drive design for manufacturing, design for assembly, serviceability, reliability, and compliance efforts with internal stakeholders and external manufacturing partners.
Govern electrical change management from change request and impact assessment through approval, drawing and bill of materials revisions, and production-line effectivity.
Plan and complete engineering transfer to manufacturing and operations, including drawings, specifications, process inputs, and open-issue handover.
Lead power electronics and distribution design from the DC tap at the host plant through conversion, harnesses and interconnects, and the compute load.
Specify protection coordination and device selection, including short-circuit calculations, breaker and fuse sizing, and conductor and busbar ratings.
Lead energy storage subsystem design, including cell and pack specifications, battery management, thermal runaway safety, and N-1 fault tolerance across parallel BESS units.
Integrate inverter and power conversion equipment across configuration, parameter sets, grid- and DC-side interfaces, and vendor technical acceptance.
Design electrical safety into the product, including isolation and disconnect architecture, stored-energy hazards, touch-safe barriers, labeling, and working clearances.
Publish and maintain released electrical design packages, including schematics, single-line diagrams, wiring and interconnect diagrams, panel layouts, cable schedules, and supporting calculations.
Own electrical design FMEA and hazard analysis through risk-priority-number reduction, mitigation closure, and sign-off against the released design record.
Develop electrical reliability and compliance test plans with quality and reliability functions, covering accelerated-life, environmental, and margin-characterization testing.
Partner with reliability on test execution and failure analysis, providing hardware, test articles, and electrical interpretation.
Plan and execute electrical root-cause investigations of production and field failures, from fault isolation and measurement through corrective action and design change.
Design, build, and commission in-line and end-of-line electrical test equipment, including fixtures, load banks, instrumentation, safety interlocks, and operator interfaces.
Support prototype and validation builds on the floor, resolve electrical build issues involving termination access, routing, and build sequence, and incorporate findings into drawings and work instructions.
Author electrical work instructions, field termination procedures, and energizing checklists for assembly and field service teams.
