Sr. Reliability Test Engineer

Aerospace is at a turning point — costs are rising, supply chains are strained, and old ways of building can't keep up. At Neon Aero, we're breaking that mold. We move fast, think big, and combine start-up agility with aerospace expertise to design, build, and scale aircraft in ways the industry has never seen. Our team leverages automation, AI-driven tools, and a fully connected digital backbone to accelerate innovation and reduce barriers to production.

Here, you won't just take a job — you'll help reinvent how the world flies. If you're ready to solve complex problems, push technology further, and work alongside some of the brightest minds in aerospace, this is your chance to make a real impact.

We are seeking a Senior Reliability Test Engineer to define, build, and execute reliability and validation testing across complex electromechanical systems.

This role sits within the systems development team and is responsible for ensuring that our products meet fundamental performance, durability, and operational requirements through rigorous engineering validation and characterization. You will own reliability test strategy, lab infrastructure, and execution for systems including electromechanical actuators, thermal management systems, and hybrid power platforms.

Your work will expose failure modes early, quantify design risk, and generate the data required to drive confident engineering decisions. While you will not own design directly, your test strategy, observations, and insights will materially influence engineering tradeoffs and system direction.

This is not a certification role. It is engineering-driven validation focused on breaking systems, understanding real-world behavior, and ensuring designs are ready before formal qualification (e.g., DO-160 and related standards). The role operates upstream of certification, but also plays a critical part during certification by providing high‑confidence data, validating assumptions, and helping streamline products through the qualification process in close partnership with systems and certification teams.

We are intentionally breaking from traditional aerospace development models. Rather than relying on extended analysis followed by a single certification-bound prototype, we build and test multiple prototypes early to uncover issues quickly and iterate based on real data. This role is central to that approach.

This is the first senior hire in reliability and validation. You will define how this function operates… from test philosophy and infrastructure to execution and scaling, establishing the foundation for how the company validates hardware as it grows.
