Senior Power Systems Engineer

Senior Power Systems Electrical Engineer – Plasma & High Voltage Location: San Francisco or Orange County office (In-person) Who We Are Omen is miniaturizing lab-grade spectroscopy into field-deployable embedded sensors. Our systems deliver PPM-level trace analysis reports on the fluids in industrial machines and datacenters, allowing us to detect complex wear trends like bearing failures or coolant contamination in real-time. With this data we can automatically match anomalies with failure modes weeks to months before catastrophic failure occurs. We don’t buildthings that are good enough, we build things that are 100x better. The Challenge We are currently developing two primary systems: Omen Scout: for closed-loop hydraulic and lubricating oils. Omen Sentry: for direct-to-chip liquid cooling loops (typ. water/glycol mixtures). Our early-stage prototypes have proven the core viability of our spectroscopy techniques, but we are looking for someone with more experience in HV power systems and/or plasma generation to formalize the power architecture for production. We need someone to lead the rigorous engineering required to take this from working prototypes to a scalable, highly controlled system. What You Will Do Own the Power Architecture: Lead the design and execution of our high-voltage power systems. You will conduct rigorous, experimentation-forward studies on plasma generation topologies and implement a highly controlled, reliable architecture for sustained emissions. Solve Fluid-Specific Challenges: Collaborate with our mechanical/mechatronics team to architect and test isolation mechanisms for the Sentry system, enabling safe and repeatable HV discharge in conductive fluids. Manage EMI: Design the necessary shielding/isolation/filtration to protect low voltage boards and sensitive optical equipment from conducted and radiated EMI. Cross-Functional Collaboration: Partner directly with our machine learning team to deliver stable hardware that provides consistent spectral data required for predictive failure modeling. What We Are Looking For Extensive experience designing high-voltage power supplies, prefer experience with both resonant and flyback topologies. Approaches problems from a fundamental physics perspective e.g. dielectric breakdown, physical chemistry, and electromagnetism. Thinks beyond reference designs i.e. first-principles approach. Practical experience managing ground loops, designing internal enclosures, and keeping logic boards operational in violently noisy electrical environments. Fast, practical, rigorous. E.g. running rapid trade studies, building benchtop prototypes, and iterating quickly to solve complex physics problems. Why Omen? We take the physics seriously, but we don’t let red tape slow us down. If you want to own a fascinating hardware problem from the ground up and build something that protects the most expensive infrastructure on the planet, we want to talk to you. #J-18808-Ljbffr
