Ambrosia Energy · Redwood, TX · Yesterday
Quality AssuranceFull-time
Responsibilities
- Design, analyze, and test highly efficient DC-DC power converters and MPPT architectures optimized for harsh, passive-cooled outdoor environments.
- Own the creation, maintenance, and execution of comprehensive electrical one-line and three-line diagrams, wiring schedules, and system schematics for standalone, off-grid microgrid systems.
- Translate complex, off-grid system requirements into detailed electrical schematics, sizing conductors, overcurrent protection devices (OCPD), disconnects, and switchgear in full compliance with relevant National Electrical Code (NEC) standards.
- Drive the technical engineering packages required for local permitting authorities and remote deployment site approvals, ensuring swift regulatory clearance.
- Optimize power distribution, load management, and stability controls for independent, islanded microgrids powering high-density computing and isolated infrastructure.
- Conduct simulation, lab testing, and validation of power electronics assemblies using oscilloscopes, hardware-in-the-loop (HIL) systems, multimeters, and power analyzers.
- Work closely with mechanical, factory automation, and field deployment teams to ensure seamless hardware build-up, standardizing on plug-and-play interconnects to minimize deployment time.
- Draft clear validation procedures and verification test plans to guide production and field technicians during system bring-up.
Qualifications
- Bachelor's degree in electrical engineering, power systems engineering, or a related STEM discipline.
- 3+ years of professional experience in power electronics design and power converter development (e.g., DC-DC, AC-DC, or standalone inverter topologies).
- Proven proficiency in electrical CAD design software (e.g., AutoCAD Electrical, SolidWorks Electrical, or similar) specifically for drafting industrial or microgrid-scale one-line diagrams.
- Hands-on experience with debugging, testing, and validating electrical systems using advanced lab equipment.
- Strong, applicable knowledge of the National Electrical Code (NEC) standards for standalone solar photovoltaic (PV) systems, DC microgrids, and energy storage integration.
- Extreme attention to detail and a relentless commitment to speed, agility, and high-quality hardware execution.
Preferred Skills
- Master's degree or Ph.D. in Electrical Engineering with a focus on power electronics or independent microgrids.
- Deep understanding of standalone solar PV string architectures, lithium-ion battery management systems (BMS), and high-voltage DC hazards.
- Experience modeling islanded power systems, transient load responses, and running short circuit and coordination studies (e.g., using ETAP, SKM, or MATLAB/Simulink).
- Prior experience working in a high-growth startup environment or an aerospace/automotive testing culture where rapid iteration is the norm.
- Direct experience engineering rapid-deployment power systems for remote, industrial, or off-grid commercial applications.
