Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

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
