## Description

Skyways designs, builds, and operates fully autonomous long-range cargo aircraft. Founded in 2017, the company has spent the last eight years developing and deploying autonomous logistics systems for real-world operations.
Our V2 aircraft carries 30 lbs up to 500 miles, while our next-generation V3 carries 100 lbs over 1,000+ miles with 20+ hours of endurance. 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 operate across three continents in controlled national airspace under FAA oversight and in support of U.S. military operations. We are transitioning from prototype development to full-rate production and scaling toward large autonomous cargo fleets.
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
