The Role 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.
You will build the test infrastructure that lets engineers and AI agents check hardware the way software teams check code. Your work will span designing and wiring test stands, writing the frameworks and CI that run them, and analyzing results from unattended test campaigns. You will work with the mechatronics, robotics, firmware and controls engineers whose systems run on your benches, and with software teams on CI and test data. You will also decide which questions need the bench and which ones simulation can answer.
What You'll Do - 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
What We're Looking For - Bachelor's degree in electrical, computer or mechanical engineering, or a related field
- Strong electrical fundamentals, including bench instruments, wiring and electrical safety
- Strong software engineering in Python, including test frameworks, CI and version control
- Systems engineering fundamentals, including tracing requirements to tests and managing interfaces
- Experience instrumenting hardware with sensors, including selection, mounting and calibration
- Experience with data acquisition, including sampling, triggering and time synchronization
- Experience flashing, debugging and testing firmware on microcontrollers
- Experience integrating and validating electromechanical systems
- Experience building automated test stands or HIL systems end to end, including instrument control over SCPI, serial, CAN or Ethernet
- Heavy daily use of AI tools and agents, with experience reviewing and verifying outputs for quality and completeness
What Will Set You Apart - Breaking open-ended validation problems into staged experiments
- Mechanical design of fixtures and test cells
- Control fundamentals for motion stages and closed-loop test fixtures
- Statistical analysis or machine learning on test data
- Integrating motors, drives and sensors into test equipment
- Programming industrial robots used inside test cells
- Machine vision for measurement or inspection on a test stand
- Defining software and hardware interfaces for shared infrastructure
