About The Position

Aerospace is at a turning point — costs are rising, supply chains are strained, and old ways of building can't keep up. Our team moves fast, thinks big, and combines start-up agility with aerospace expertise to design, build, and scale aircraft in ways the industry has never seen. We leverage 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. Role Overview We are seeking a Reliability Test Engineer to define, build, and execute engineering validation and reliability testing across complex electromechanical systems. This role supports development programs spanning aerospace actuation systems, thermal management systems, power electronics, energy systems, and related high-performance hardware. This is a hands-on engineering role focused on validating real hardware under real operating conditions. The ideal candidate understands how to translate engineering questions into practical test methods, execute structured validation campaigns, identify failure modes, and generate actionable data that improves product design and reliability. Note: This is not a pure compliance or certification role. The focus is engineering-driven validation, characterization, durability testing, and failure discovery during product development.

Requirements

Bachelor's degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, Systems Engineering, or a related field.
5-8 years of professional experience in hardware test, validation, reliability, or systems integration engineering.
Hands-on experience developing and executing engineering test campaigns on electromechanical systems.
Experience with instrumentation, DAQ systems, sensors, and engineering lab equipment.
Experience troubleshooting hardware failures and supporting root cause investigations.
Strong understanding of engineering fundamentals including mechanics, thermal systems, electronics, or controls depending on background.
Experience working in lab and prototype environments with evolving hardware, with the ability to analyze and communicate technical data clearly.

Nice To Haves

Experience with environmental or durability testing including vibration, thermal cycling, humidity, or shock testing.
Experience with aerospace, automotive, robotics, defense, or other high-performance hardware systems.
Familiarity with standards such as DO-160, MIL-STD-810, IEC, or similar environmental qualification frameworks.
Experience with Python, MATLAB, LabVIEW, or scripting tools for test automation and data analysis.
Experience supporting HIL, SIL, or integrated system-level test environments.
Exposure to electric propulsion systems, power electronics, batteries, actuators, or embedded systems.

Responsibilities

Develop and execute validation and reliability test plans for electromechanical and integrated systems.
Design and build test setups, fixtures, instrumentation, and data collection systems for engineering validation activities.
Support environmental, functional, durability, vibration, thermal, and lifecycle testing of prototype and production-intent hardware.
Work closely with Mechanical, Electrical, Embedded Software, and Systems Engineering teams to define validation objectives and acceptance criteria.
Operate and troubleshoot lab equipment including DAQ systems, power supplies, oscilloscopes, thermal instrumentation, environmental chambers, and electromechanical test equipment.
Collect, analyze, and interpret test data to identify trends, failure modes, and performance limitations.
Develop automated test scripts, data processing tools, or reporting workflows using Python, MATLAB, LabVIEW, or similar tools where appropriate.
Support root cause investigations and failure analysis activities across hardware and integrated systems.
Support prototype builds, integration efforts, and rapid iteration cycles in a fast-moving hardware development environment.
Participate in design reviews and provide feedback related to testability, reliability, and validation strategy.
