Principal Software Engineer

Performance Drone Works (PDW) is building the next generation of tactical robotic systems used across defense, national security, and public safety missions. As we expand into Denver, we are building a new center of engineering excellence to design our new category of tactical robotic systems and the industrial capacity to deliver them, bringing decisive airpower into the hands of every operator. We are not here to make promises; we are here to deliver real systems with real capabilities for real missions. 
You will join a team of operators, engineers, and builders who solve hard problems with humility and focus. We design and produce multi-mission aerial systems that operators trust to perform in real-world conditions, reliably, repeatedly, and at scale. Our approach is grounded in operator-centered design, rapid iteration from field use, and U.S.-based manufacturing. We operate by a clear set of values: Mission First, Aim Farther, Own It, Win Together. This is how we build advantage and how we help protect our service members, our communities, and our country.
