Test Engineer, Hardware and Systems

S. military and its allies. We believe that credible deterrence of armed conflict and winning if deterrence fails, requires more than just the best drones, sensors, weapons, electronic warfare systems, and command control capabilities.

Those critical components will require sustained electric power in austere and resource-constrained environments. Moreover, military units must be able to turn off the trucks and generators that generate this power to hide and survive. In other words, power generation must be decoupled from power consumption.

S. and allied militaries to be more lethal and survivable. We hope you will join us on this mission.

About The Role

Chariot Defense is looking for a Test Engineer to own hardware validation across our power systems across mechanical, electrical, thermal, power electronics and controls, performing component-level all the way to full system integration testing in environmental and operational conditions. You'll sit at the intersection of hardware, firmware, and systems engineering, building the test infrastructure and executing the validation strategy that gets Amphora and future cutting-edge products in energy and power storage, and mobility, from prototype to fielded. S.

military. We build hardware that operators depend on in the field — and we validate it like lives depend on it, because they do. We emerged from stealth in 2025, are already fielded across DoD exercises, and are backed by General Catalyst, a16z, and DCVC.

This is a high-ownership, high-impact, hands-on role. You'll write the test plan, build the fixture, develop the electronics, controls, and firmware, run the test, triage the failure, and close the loop with design.

Key Responsibilities

Design, build, instrument, and automate test equipment for electrical, mechanical, thermal and environmental validation of hardware — batteries, inverters, DC-DC converters, controllers/ ECUs, distribution units, and integrated Amphora systems Own hardware unit-level test station development: design specialized automated test equipment (ATE), write test scripts, and maintain test coverage as hardware evolves Execute component, subsystem, and system-level validation across electrical, thermal, and mechanical dimensions — including high-voltage characterization and fault injection Develop and run environmental test programs per MIL, energy, and automotive specs: temperature cycling, vibration, shock, ingress, corrosion etc. Collaborate with firmware engineers to validate embedded control logic, power management algorithms, and system behavior under real and edge-case conditions Interface with design engineers to identify failure modes early, generate DVP R entries, and drive design changes based on test findings Build and maintain DAQ systems; automate data collection and post-processing pipelines in Python, LabVIEW, Matlab/ Simulink or similar tools.
