About The Position

We’re seeking a Power Distribution Engineer to design and implement reliable power architectures for complex electronics and test systems. You will own power sequencing (voltage rail order, timing, and interlocks), PCB-level power distribution, and relay/contactor control logic to ensure safe bring-up, robust operation, and clean shutdown across electro-mechanical assemblies. This role is ideal for an engineer who enjoys practical design ownership – requirements to schematic/PCB, build and debug – and who is comfortable working across analog power, digital control, and system integration.

Requirements

BS in Electrical Engineering, or related field.
Experience designing power distribution and sequencing for multi-rail electronics (startup/shutdown timing, dependencies, and fault behavior).
PCB design experience (schematic capture + layout) for power and mixed-signal boards.
Hands-on experience with relay/contactor or load-switch control and protection (inrush, fusing, current limiting, isolation).
Strong debugging skills with standard lab tools; ability to diagnose intermittent and transient power issues.
Comfort working with requirements, producing documentation, and collaborating with firmware/test/mechanical teams.
U.S. citizenship required
Active TS/SCI

Nice To Haves

Experience with power management ICs (PMICs), sequencing controllers, and power monitors.
Firmware or programmable logic experience for relay control and power state machines (embedded C/C++, FPGA/PLC, or scripting).
Experience with high-current / higher-voltage distribution (e.g., 28 VDC, 48 VDC, or kV) and safety standards/practices.
EMI/EMC awareness for power systems (layout practices, filtering, grounding/shielding, conducted emissions mitigation).
Experience with configuration control and manufacturing test bring-up; writing procedures and work instructions.

Responsibilities

Design power distribution and sequencing architectures for multi-rail systems (define rail order, timing, dependencies, and safe-state behavior).
Develop relay/contactor control logic and interlocks (hardware + firmware/logic as applicable) to support controlled power-up/down, fault isolation, and emergency-off behaviors.
Create schematics and PCB layouts for power distribution, load switching, and protection circuits (fusing, current limiting, TVS/ESD, reverse polarity, inrush control).
Select and integrate power components (DC/DC converters, LDOs, hot-swap/controllers, power monitors, relays/contactors, connectors, harnessing).
Implement and validate power health monitoring: voltage/current sensing, sequencing status, fault flags, and telemetry for troubleshooting and preventive maintenance.
Perform bring-up and debug using lab instrumentation (oscilloscope, DMM, current probes, power analyzers, electronic loads); characterize transients, inrush, droop, and EMI contributors.
Define and execute verification plans for sequencing and safety requirements; develop test procedures and acceptance criteria.
Support system integration: grounding/bonding strategy, cable/harness design, connector pinouts, and environmental/field readiness considerations.
Document designs and changes clearly: schematics, layouts, timing diagrams, logic truth tables/state machines, and troubleshooting guides.
