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.

Our team is a tightly knit group of ~20 builders, dropouts, and industry veterans.
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 R&D team has proven the science works on the bench, but our sensors are
going into harsh and high-rel environments, e.g. high-temp industrial hydraulics
and mission-critical datacenter cooling loops. We need a Test Engineer to
systematically stress, break, and validate our hardware to ensure it survives a
lifetime of continuous use.

What You Will Do
Architect Test Systems: Design, build, and maintain the custom
automated test fixtures required to run our prototypes through thousands
of cycles. Utilize our existing fluidics robots to automate the creation of test
samples for those cycle tests.
Environmental & Stress Testing: Own the execution of thermal, vibration,
fluid pressure, and HALT/HASS testing on our sensor packages.
Data Acquisition & Scripting: Write automated test scripts (e.g., Python)
to pull continuous data from sensors under test and flag anomalies.
Root Cause Analysis: Tear down failed units with the engineering team,
driving RCD to understand failure modes and mitigate them in future units.

What We Are Looking For
Proven experience building custom automated test rigs involving
electromechanical components, fluid loops, or high-voltage systems.
Strong proficiency in non-LabVIEW scripting languages (e.g. python) for
test automation and data parsing.
Familiarity with data acquisition hardware (DAQ) and sensors
(thermocouples, pressure transducers, flow meters).
Experience outsourcing certain tests to 3rd party labs e.g. UL, IP67, FCC, etc.
Experience with MCAD software (Solidworks) to make fixtures and tweak
existing designs accordingly.
A destructive, analytical mindset, takes pride in finding the breaking point
of hardware before our customers do.

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.
