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 build things 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.
