Hadrian Automation Test Automation Engineer at Hadrian Automation responsible for building hardware-in-the-loop test stands and test frameworks. The role involves designing test infrastructure, integrating tests into CI, and running unattended test campaigns for hardware validation.

Responsibilities

Applied Physical Systems is a small, cross-functional engineering team at Hadrian. We build technology that spans more than one manufacturing capability, needs hardware and software designed together, and can't be bought off the shelf. We take a solution from proof of concept through prototype to a first production-ready version, then hand it to the teams that run it at scale. Engineers on the team design, build and commission their own systems on the factory floor.
Design and build hardware-in-the-loop (HIL) test stands for robots, end effectors, sensors and machine subsystems
Build test frameworks, including instrument and device control, fixtures, stimulus, results schema and dashboards
Add bench tests to CI so that firmware and hardware changes run on real hardware before release
Build safe interfaces for AI agents to run tests and experiments on real hardware
Run unattended, repeatable test campaigns and report results with their statistical confidence
Decide which questions simulation can answer and which ones need the bench
Keep test infrastructure running as a service that other teams depend on
Support integration and acceptance testing of new automation before it reaches production
