Requirements

BS or MS in Electrical Engineering, or related degree.
3+ years of experience in end-to-end circuit design, component selection and specification, electrical architecture trade-offs, ASIL redundancy/ functional safety, embedded systems troubleshooting, and electronics testing.
Proficiency with CAD tools (preferred, Altium), simulation software (preferred, MATLAB/Simulink/Spice)
Competence with test equipment such as oscilloscopes, function generators, low and high voltage programmable power supplies, spectral, logic, and impedance analyzers, debuggers, voltage probes, current clamps, and automation of tests, reflow techniques, soldering, connector selection and integration etc.
Fluent in CAN BUS protocols (preferred, J1939, CANOPEN) and other low-voltage networking protocols.
Familiarity with MIL-STD, DO-160, or other automotive, defense, and aerospace standards.
Strong problem-solving and troubleshooting skills.

Nice To Haves

Experience designing and working directly with low and high voltage energy storage systems, high current/ high voltage power distribution, and voltage regulating power electronics.
Experience with advanced circuit modeling tools such as LTSpice and multiphysics systems such as Comsol, and familiarity with common and less frequent complex circuit dynamics (e.g.: oscillations, ringing, ground bounce etc.)
Experience designing, and debugging, various end-point nodes on an electrical grid such as motors, sensors, resistors, other inductive/ capacitive/ resistive loads
Experience designing low-side and high-side circuit switches, half and full bridges, advanced noise filters and power stabilizers, fly back diode circuits, passive and active discharge systems etc.
Experience with critical managing radiated emissions for minimizing any RF signatures, and designing for immunity from external RF spectra, and some exposure to broadband amplifiers, antennas, near-field probes etc.
Experience in industries/applications requiring high-reliability embedded power electronics operated in austere environments.
Familiar with U.S. and NATO operational requirements, particularly the Tactical Microgrid Standard.

Responsibilities

Design & Development: Create schematics, layouts, and circuit designs for low- and high-voltage power electronics systems coupled with advanced energy storage, management, and safety systems, optimizing for stable circuit dynamics, power efficiency, latency, electrical safety and system protection, and abuse loading cases, to name a few.
Testing & Validation: Perform circuit simulations, bench testing, and system-level validation to ensure compliance with military and industry standards.
System Integration: Collaborate with mechanical, thermal, software, and systems engineers to integrate electronics into cohesive and elegant products, carry out electrical and system integration, and manage tight coupling between electrical IO’s and firmware behavior.
Reliability Engineering: Apply design-for-reliability practices, including EMI/EMC mitigation, ruggedization for harsh environments, and thermal management.
Documentation & Compliance: Generate technical reports, test plans, and ensure adherence to MIL-STD and other defense specifications.
Lifecycle Support: Provide engineering support throughout the product lifecycle, from concept through field deployment and sustainment.
