Sr. Hardware Test Engineer
Mountain View, CAApril 2nd, 2026
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 Sr. Hardware Test Engineer at Reliable Robotics, you will be a critical 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. You will be one of the essential interfaces between the design, production, and flight test teams and will be exposed to a wide variety of technical challenges.
You will be architecting 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. You will be a technical leader on a team eager to learn and grow.
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
Help the team grow and provide mentorship to peers
Basic Success Criteria
B.S. Degree in Mechanical, Electrical, Aerospace, Computer Science, Software Engineering or equivalent industry experience
5+ years of industry experience testing hardware in a regulated industry
Professional knowledge of ECAD tools such as Altium OR MCAD tools such as NX
Experience with software design and implementation in Python or C/C++
Strong understanding of mechanical or electrical engineering fundamentals
Eagerness for hands-on work - integration of sensors, building test fixtures, diagnosing and debugging equipment and hardware
Proven ability to methodically diagnose, document, and solve hardware problems
A demonstrated passion for mechanical, electrical, or electromechanical hardware
Preferred Criteria
8+ years experience in aerospace test planning and execution
A history working on and around aircraft
Prior experience with aerospace qualification testing standards (MIL-STD-810, RTCA DO-160, or similar) and the aircraft certification process
Comfort reviewing technical designs and working from drawings, schematics, layouts, assembly/procedures, master parts lists, and other controlled documentation
Mastery of test instrumentation and data collection methods; ability to design a data acquisition system from the ground up
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
Eagerness to learn, teach, and adapt; help us grow as both a development and production operation
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.
The estimated salary range for this position is $180,000 to $260,000/annual salary + cash and stock option awards + benefits. At Reliable Robotics, we strive to provide competitive and rewarding compensation based on experience and expertise, as well as market conditions, location, and pay equity.
In addition to base compensation, Reliable Robotics offers stock options, employee medical, 401k contribution, great co-workers and a casual work environment.
This position requires access to information that is subject to U.S. export controls. An offer of employment will be contingent upon the applicant's capacity to perform in compliance with U.S. export control laws.
