Job summary

Swarm Aero is building the first swarming aircraft and the companion avionics test infrastructure. You will own hardware-in-the-loop test systems, develop fixtures and interfaces, and run automated validation that helps engineers catch issues early and verify every unit we build.

This hands-on role spans from bench setup to aircraft integration and production. You’ll work with avionics, embedded software, flight controls, and manufacturing teams to turn requirements into practical tests,

Qualifications

• Experience developing HIL systems, automated hardware test equipment, or functional testers for complex electronic systems.
• Strong electrical engineering fundamentals and hands-on experience integrating and troubleshooting hardware.
• Proficiency in Python, C/C++, LabVIEW, or similar languages and tools used for test automation.
• Experience with embedded interfaces and communication protocols such as CAN, Ethernet, UART, SPI, or I²C.
• Ability to read schematics and develop test fixtures, harnesses, and interface hardware.
• An understanding of how to turn requirements into meaningful test coverage and diagnose failures across hardware and software.
• A track record of taking a test system from concept to a reliable tool other engineers or technicians can use.

Responsibilities

• Design, build, and bring up HIL systems that connect flight hardware with simulated aircraft systems, sensors, and operating environments.
• Develop functional testers for avionics components and assemblies, including test fixtures, interface electronics, harnesses, instrumentation, and automated software.
• Work with avionics, embedded software, flight controls, and manufacturing teams to turn system requirements into practical tests with clear pass/fail criteria.
• Develop automated test sequences for nominal operation, fault injection, and recovery behavior.
• Debug electrical, software, and integration issues using schematics, logs, oscilloscopes, logic analyzers, and other bench tools.
• Establish repeatable test methods, configuration control, and useful reporting across engineering and production.
• Improve test coverage, reliability, and execution time as hardware matures and production scales.
