SeniorReliability&TestEngineer

As Senior Reliability & Test Engineer at Fauna, you will build the reliability discipline from the ground up and lead the test engineering function for our robotic hardware products. You will define how we prove that our systems meet performance, durability, manufacturability, and field reliability requirements across the full product lifecycle — from early prototypes through DVT, PVT, production ramp, and field operation. This is a hands-on technical leadership role with function-level ownership from day one. You will set reliability strategy, define validation standards, lead engineering and production test strategy, and build the systems that connect reliability qualification, production test, failure analysis, and field performance. You will set the direction for test engineering, raise execution standards across the existing team, and build Fauna’s reliability function from the ground up. Key job responsibilities - Build the reliability engineering discipline from the ground up by defining reliability requirements, validation targets, qualification standards, test methods, data systems, and closed-loop learning from field performance - Own the product reliability and test strategy across development milestones, from prototype builds through DVT, PVT, production ramp, and field operation - Design and execute reliability qualification programs, including HALT, ALT, life testing, environmental stress testing, durability testing, and abuse/misuse testing where applicable - Analyze reliability test results, identify dominant failure modes, quantify risk, and drive design, material, process, supplier, or test-coverage changes based on findings - Lead the test engineering function for Fauna's robotic hardware products, including test strategy, technical direction, infrastructure, standards, and execution quality - Define and own production test strategy at our contract manufacturer, including acceptance criteria, end-of-line coverage, test data capture, and test infra
