SpaceX is seeking a Senior Solar Cell Reliability Engineer to own the solar cell reliability program for Starlink hardware. This on-site role, based in Bastrop, Texas, will manage the reliability lab and the end-to-end reliability story for HJT solar cells—from wafer processing and cell fabrication through module integration, environmental qualification, on-orbit performance, and continuous improvement back into manufacturing. Responsibilities include operating and improving the solar cell reliability lab (equipment strategy, calibration, safety, throughput, and data integrity); defining and executing the space reliability test matrix (thermal cycling, thermal vacuum, humidity/damp heat, UV/photo-stability, reverse bias, electrical and thermal stresses, mechanical shock and vibration at cell level, radiation exposure coordination, and accelerated life tests); building the reliability narrative for flight and program reviews (failure modes, physics of failure, acceleration models, life predictions, margins, and acceptance criteria); collaborating with HJT process and equipment engineering to link process parameters and metrology to reliability outcomes; establishing reliability gates for process changes, tool qualifications, material substitutions, and supplier changes; developing test methods, SOPs, fixtures, and automation for high-throughput, statistically defensible reliability characterization; leading root cause analysis on reliability failures using SEM/FIB, EDS, FTIR, PL/EL, IV, and other failure-analysis techniques; defining and tracking reliability KPIs and reporti
