Reliability Design Engineer - Motors, Mechanisms and Electronics

About the RoleAs a Reliability Design Engineer, you will build the test infrastructure that lets us predict and prevent failures in the lab, before our robots ever reach a customer's home. The mission is simple to state and hard to do: catch it here, not in the field. You will work closely with our mechanical design engineers, electrical design engineers, quality engineers, production engineers, and supply chain teams to make sure we are doing everything possible to fully test and validate every feature before we ship it.This means pushing our designs to the extreme and building in real design margin, so that when people start depending on these robots for their daily chores and work, the robots don't fail them. That is how we fulfill our promise of a world-class home robot people genuinely love. Your work is the difference between a customer who trusts their robot and one who doesn't.This is a hands-on hardware role for an engineer who likes building things that break other things. You will design, fabricate, instrument, and run the rigs, fixtures, and accelerated torture tests that reproduce real-world failure modes, push our designs past their limits, and tell us exactly where and why things break. You will model a rig in CAD, wire up the motor drivers and sensors that bring it to life, stand up the data acquisition that captures clean failure data, and write the scripts that automate it all. And you'll do it at serious scale: we are ramping from thousands of robots today toward hundreds of thousands a year, across a fast-moving lineup of hardware versions, which means the test systems you build have to be as robust, repeatable, and scalable as the products they protect. If you want to design clever electromechanical apparatus, get your hands dirty, and have a direct line of sight from your work to a more reliable product in someone's home, this role is for you.What You'll DoDesign, fabricate, and iterate electromechanical test rigs, fixtures, and automated setups that reproduce field failure modes and stress our designs to failureBuild accelerated life, fatigue, vibration and shock, and temperature and humidity tests across motors, mechanisms, and electronicsWire up and integrate the actuators, motor drivers, sensors, and data acquisition that bring each test setup to life and capture clean, analyzable failure dataWrite scripts to automate test execution and data logging so tests run reliably and repeatably at volumePartner with reliability engineers to translate physics of failure and field insight into representative test methodsSupport root cause failure analysis by designing the apparatus and experiments that isolate failure mechanismsCreate and maintain CAD models, drawings, and documentation for all test equipmentScale and maintain the reliability lab as our fleet, hardware versions, and test volume growWork cross-functionally with mechanical, electrical, software, quality, production, and supply chain teams to close the loop from potential failure to design fixWhat We Look ForTechnical degree in mechanical engineering, electrical engineering, mechatronics, or a related hardware discipline2+ years of hardware design engineering experience, ideally on a physical product that has shipped in volumeProven ability to build, fabricate, and rapidly iterate physical prototypes and test setupsProficiency in CADHands-on comfort across electromechanical systems: actuators, motor control, sensors, and basic circuit work, data acquisition, and instrumentationWorking proficiency with a scripting language such as Python for test automation and data handlingExposure to reliability and test concepts such as accelerated testing, fatigue, life testing, DOE, or FMEA is a plusComfort with a fast-paced, startup atmosphere where you take ownership of ambiguous problemsHigh level of maturity, ownership, and pride in your workWe'd Love to Hear From You If...You are genuinely motivated to help those around youYou are passionate about learning outside of your normal comfort zonesYou love diagnosing complex technical issuesYou are excited to do great workCompensation:Base: $120,000 - $200,000 per annum.Actual compensation will depend on skills, experience, and qualifications. Base salary is one part of the total compensation package.
