Senior Subsystem Test Engineer

Skyways designs, builds, and operates fully autonomous long range cargo aircraft. Founded in 2017, the company has spent nearly a decade developing and deploying autonomous logistics systems for real world operations. Our V2 aircraft carries 30 lbs up to 500 miles, and V3 has a maximum range of well over 1,000 miles, a maximum useful load of 100 lbs, and a maximum endurance of nearly 20 hours. Both use a hybrid electric architecture that takes off like a helicopter and cruises like a plane, enabling long range autonomous delivery without traditional runway infrastructure. Today, Skyways aircraft fly revenue missions for commercial customers across three continents. We are scaling full rate production and building toward large fleets of autonomous cargo aircraft. Backed by Y Combinator and a $37M AFWERX STRATFI award from the U.S. Air Force, Skyways is creating a new form of transportation to advance our civilization from Austin, Texas. The Opportunity This role owns how aircraft systems are validated before flight. You will develop and execute subsystem test programs across structures, propulsion, electrical systems, avionics, and integrated aircraft hardware. Your work will directly impact aircraft reliability, development speed, and flight readiness. You will build the infrastructure needed to test complex systems quickly and accurately, including fixtures, instrumentation, data acquisition systems, and automated test workflows. The role requires strong engineering fundamentals, hands-on execution, and the ability to diagnose problems across mechanical and electrical systems. You will work closely with mechanical, electrical, software, manufacturing, and flight test teams to identify failures early, improve system reliability, and support rapid aircraft iteration. The ideal candidate is comfortable building test systems from scratch, troubleshooting hardware issues directly, and operating in fast-moving hardware development environments. What You'll Do:

Develop and execute subsystem test plans for aircraft hardware and integrated systems

Design and build test fixtures, instrumentation setups, and data acquisition systems

Support testing across structures, propulsion, electrical systems, avionics, and integrated aircraft hardware

Mentor junior test engineers and raise the bar for how test programs, fixtures, and data analysis are built and run across the team

Analyze test data and identify system failures, performance gaps, and reliability issues

Troubleshoot mechanical, electrical, and integration issues during testing activities

Collaborate with engineering teams to improve subsystem performance and validation processes

Develop automated test workflows, documentation, and test procedures

Support ground testing, aircraft integration, and flight test activities

What You'll Bring:

5+ years developing and executing tests for complex hardware systems, including building test infrastructure from scratch

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or related field

Experience developing and executing tests for complex hardware systems

Hands-on experience with instrumentation, sensors, signal conditioning, and data acquisition systems

Strong troubleshooting skills across mechanical and electrical systems

Experience analyzing test data and diagnosing system-level issues

Ability to work directly with hardware in lab, production, or flight test environments

Strong communication and cross-functional collaboration skills

Ability to operate effectively in fast-moving engineering environments

Bonus Points If You've:

Participated in Formula SAE, Baja SAE, Solar Car, Intercollegiate Rocket Engineering Competition, Design Build Fly (DBF), FIRST Robotics, Battlebots, etc.

Experience with aerospace, UAV, robotics, automotive, or other high-performance hardware systems

Experience supporting propulsion, battery, avionics, or environmental testing

Familiarity with Python, LabVIEW, MATLAB, or automated test frameworks

Experience supporting flight test or operational hardware deployments

Experience with environmental, vibration, thermal, or structural testing

In addition to base salary, offers include stock options, so you own part of what you build. Benefits include medical, dental, and vision coverage, paid time off, paid holidays, a 401k, and life insurance. Relocation assistance is available for candidates moving to Austin.
