Requirements

Bachelor’s degree or higher in Electrical Engineering or related field.
7+ years of relevant industry experience in system-level power electronics.
Direct experience with High Power (25-250kW) Hybrid Inverters and DC-DC conversion.
Familiarity with AC switching/transfer logic and protection coordination.
Ability to perform "worst-case" analysis and simulations (SPICE/PLECS) to ensure design robustness.
Proficiency in PCB layout with a focus on DFM (Design for Manufacturing).
Proficiency in Altium Designer (or similar) with specific experience in high-current/high-voltage layout.
Proficiency in 3D CAD software (e.g., SolidWorks, NX, or Creo). Demonstrated experience working in PDM and/or PLM environments.
Expert-level use of PLECS, PSIM, or MATLAB/Simulink to simulate power stages and control loops before building hardware.
Demonstrated knowledge of UL 1741 and IEEE 1547.
Hands-on experience with heat sink sizing, fan selection, and thermal interface materials to keep the system stable under load and operating environment requirements.
Demonstrated firmware experience, specifically C/C++ for microcontrollers to ensure the hardware and software are aligned.
Experience with development testing, failure analysis, and debugging complex systems. The successful candidate will own and drive documentation and configuration management.
Comfortable working in an environment based on accountability: scope, schedule, budget, 2-way feedback and collaboration.
Familiar with modern engineering collaboration toolsets: Confluence,, Slack, Asana, etc.
Demonstrated experience reading electrical schematics/drawings.
Demonstrated ability to operate in a fast-paced, start-up environment. Hands-on and biased towards action.

Responsibilities

Design and bring up the Hybrid Inverter, converter, switches and battery management system architectures with a focus on speed-to-prototype.
Design the switching logic and hardware to allow the onsite AC load to be powered by either the hybrid system or the grid.
Build the "charge-and-switch" logic, ensuring the system can buffer energy from the generator and manage the transition between battery, generator, and grid power.
Source components from multiple vendors to avoid long lead times. You prefer "available now" over "perfect in six months."
Use your mechanical aptitude to ensure electronics fit physical constraints, accounting for thermal management and ruggedized packaging.
Thrive in a tight-knit environment where you help define requirements for software and mechanical peers to move the whole project forward. Directly support design, test readiness and test data reviews.
Develop test plans and perform development testing for verification and validation of assemblies.
Create and maintain system electrical schematics.
Adhere to relevant safety standards.
Document assembly and operating procedures for new equipment and systems.
