Embedded Software Test Engineer
Quick Summary
About Us Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We are looking for a Software Test Engineer to own the validation of our complex radar payload. In this role, you will bridge the gap between hardware and software, writing the code that proves our system works. You will develop specialized firmware to exercise our FPGAs, RF front-ends, and antenna arrays, while simultaneously building high-level Python automation to orchestrate test campaigns. You will work in a hands-on lab environment, pushing our hardware to its limits to ensure it survives and performs in the extreme conditions of space.
Responsibilities
~1 min read- →
Design and implement automated test frameworks in Python to characterize the performance of radar, RF, and antenna subsystems.
- →
Write firmware in C/C++ to stimulate hardware interfaces, inject test patterns into FPGAs, and control RF transceivers during validation.
- →
Develop Hardware-in-the-Loop (HIL) test setups that integrate flight software, ground station commands, and simulated environmental data.
- →
Automate the control of laboratory test equipment (Signal Generators, Spectrum Analyzers, Network Analyzers, Oscilloscopes) to capture and analyze system performance data.
- →
Collaborate with FPGA and RF engineers to define test requirements and debug complex hardware-software integration issues.
- →
Analyze test data to identify trends, performance regressions, and potential hardware failures before they reach orbit.
- →
Maintain and upgrade continuous integration (CI) pipelines that run automated tests on physical hardware targets.
