The node combines high-power GPUs and CPUs, a heat-pump liquid-cooling loop, battery storage, and modular serviceability. This is not a classic raised-floor data-center reliability role and not a consumer-product reliability role. You define what “reliable enough” means for unattended outdoor operation across climates (hot climates matter), generate the evidence that the design meets it, and close the loop from test and field data back into design and process.\nResponsibilities\nOwn Design for Reliability (DFR) for the XFRA node: set reliability targets and mission profiles for outdoor residential and commercial sites; create and maintain DFMEA/XFMEA across thermal, electrical, mechanical, fluid, and systems interfaces.\n\nPlan and drive reliability testing appropriate to the node: thermal and power cycling, liquid-cooling loop durability (coolant, seals, pumps, heat exchangers), environmental stress (temperature extremes, humidity, dust, UV), vibration, and accelerated life methods that map to real site conditions.\n\nAnalyze test and early field data with statistical methods; convert results into design requirements, derating guidance, supplier actions, and corrective/preventive changes.\n\nLead or guide root-cause investigations on prototype and early-field failures; ensure findings result in concrete design, component, or process changes.\n\nCollaborate with mechanical, thermal, electrical, firmware, and certification engineers on system-level risks (heat-pump cooling, battery integration, outdoor enclosure, SPAN Panel power interface, serviceability).\n\nSupport development of test methods and lab capability for outdoor liquid-cooled compute hardware; manage external test partners where needed.\n\nContribute to serviceability and maintainability targets so field repair remains practical as the install base grows.\n\nAbout You\nRequired Qualifications\nBS or MS in Mechanical Engineering, Electrical Engineering, Materials Science, or a related field.\n\n6+ years in reliability engineering with clear ownership of programs on complex electro-mechanical or thermal systems.\n\nHands-on experience with FMEA/DFMEA, reliability test planning and execution, and statistical analysis of test data (Weibull, accelerated-life models, DOE).\n\nTrack record of translating lab or field data into design or process changes on products that operate outside controlled environments.\n\nAbility to work across mechanical, thermal, electrical, and firmware boundaries and communicate reliability implications clearly to design owners.\n\nBonus Qualifications\nOutdoor or harsh-environment systems: liquid cooling, heat pumps, HVAC, energy storage, outdoor telecom/industrial equipment, or similar.\n\nLiquid-cooling loop reliability (coolant chemistry, seals, pumps, heat exchangers) or high-power electronics thermal management.\n\nExperience with dense compute, GPU servers, or power electronics outside traditional data-center environments.\n\nPython or equivalent for data analysis and test automation.\n\nHot-climate or outdoor deployment experience.\n\nFamiliarity with relevant environmental or reliability standards (IEC, UL, or prediction methods).\n\nLife at SPAN\nHeadquartered in San Francisco’s vibrant SoMa neighborhood, we are an eclectic group of creative thinkers who value open communication, teamwork, and a ‘make it happen’ approach to addressing complex challenges.\nSPAN embraces diversity and equal opportunity in a serious way. We are committed to building a team that represents a variety of backgrounds, perspectives, and skills.\nWe’re hiring talented individuals who are driven by success and are passionate about shaping the future of renewable energy. If that sounds like you, we’d love for you to consider joining the rapidly growing team at SPAN.\nThe Perks:\nCompetitive compensation + equity grants at a well-funded, venture-backed company\nComprehensive benefits: 100% employee premiums for base plans on medical, dental, vision with options for additional coverage. Parental leave up to twenty four (24) weeks depending on eligibility\nComfortable, sunny office space located near BART and Caltrain public transit\nStrong focus on team building and company culture: Employee Resource Groups, monthly social events, SPANcakes recognition breakfast, lunch, and learns\nFlexible hours, one holiday per month, and flexible time off\nInterested in joining our team?
