We're building safety-enhancing technology for aviation that will save lives. Automated aviation systems will enable a future where air transportation is safer, more convenient and fundamentally transformative to the way goods — and eventually people — move around the planet. We are a team of mission-driven engineers with experience across aerospace, robotics and self-driving cars working to make this future a reality.
As a Hardware Test Engineer at Reliable Robotics, you will be a key part of the Hardware Test team. This is a small team of broadly experienced engineers that strive to ensure that all hardware being produced meets the stringent requirements for aviation. Hardware Test Engineers are one of the essential interfaces between the design, production, and flight test teams and are exposed to a wide variety of technical challenges.
You will be creating automated test stands to replicate extreme flight conditions on our hardware and mechanisms that will serve as the backbone of our qualification testing. You will help to break our development hardware, help root-cause the failure modes, and provide critical input in redesigning it. You will be writing the software and building the hardware platforms for the command, control and data collection systems that will test our systems to rigorous aerospace standards.
Responsibilities
- Full ownership of the design, build, and maintenance of mechanical or electrical test stands for development testing, production acceptance testing, functional and environmental qualification testing
- Automate the repetitive aspects of the test stands
- Author, execute, and audit test plans, procedures, and reports
- Work closely with design engineers and flight test engineers to design, build, test and improve flight hardware
Basic Success Criteria
- B.S. Degree in Mechanical, Electrical, Aerospace, Computer Science, Software Engineering or equivalent industry experience
- 1+ year of industry experience testing hardware
- Experience using ECAD tools such as Altium or MCAD tools such as NX
- Comfort with basic software scripting in Python, C/C++, or MATLAB
- Working understanding of mechanical or electrical engineering fundamentals
- Eagerness for hands-on work - integration of sensors, building test fixtures, diagnosing and debugging equipment and hardware
- Ability to methodically diagnose, document, and solve hardware problems
- A demonstrated passion for mechanical, electrical, or electromechanical hardware
Preferred Success Criteria
- 2+ years experience in aerospace hardware test planning and execution
- Experience working on and around aircraft
- Knowledge of aerospace qualification testing standards (MIL-STD-810, RTCA DO-160, or similar) and the aircraft certification process
- Experience reviewing technical designs and working from drawings, schematics, layouts, assembly/procedures, master parts lists, and other controlled documentation
- Familiarity with test instrumentation and data collection methods such as NI DAQ, UEI DAQ, LabJack, etc.
- Working understanding of measurement and data analysis; ability to clearly present technical data and state its limitations
- Demonstrated proficiency building/fabricating machine parts, cable assemblies, or other testing, integration, or assembly experience
As a member of our team, you will be a pivotal contributor to the development of novel hardware that will transform the future of flight. From component level thermal testing to instrumenting our aircraft with a sensor suite for flight testing, you will closely interface with many vital parts of our system. The cross-functional nature of this role also lends itself to mentoring opportunities across the entire company.
This role is located onsite at our HQ in Mountain View, CA.
Must be willing to travel 10% of the time.
