Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.\nSpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.\nABOUT THE ROLE:\nAs a Site Reliability Engineer focused on Hardware, you will serve as an expert focused on firmware, hardware specifications, vendor relations, and failure analysis. You will proactively identify and resolve hardware issues, manage RMA processes, and stay ahead of emerging hardware technologies to support SpaceXSI's data center operations. This role demands deep technical expertise in hardware diagnostics, and forward-looking hardware evaluation.\nRESPONSIBILITIES:\nAnalyze firmware packages and hardware specifications for upcoming releases for compatibility, performance, and reliability in SpaceXSI's data center environment. Run security scanning and CVE / vulnerability analysis on firmware and related components. Flag safety issues (electrical, thermal, power-protection, fail-safe behavior) before the package hits the floor.\nInvestigate and diagnose hardware failures, including \"grey failures\" (ambiguous or intermittent issues), proving them as true hardware defects through rigorous testing and data analysis.\nManage vendor relationships, including initiating RMA (Return Merchandise Authorization) claims, negotiating beyond standard processes when necessary, and holding vendors accountable for resolutions.\nCollaborate with Data Center Operations Technicians to troubleshoot, repair, and optimize hardware systems in real-time.\nDevelop and implement monitoring tools, scripts, and processes to detect hardware anomalies early and minimize downtime.\nDocument failure modes, RCAs, AFR / reliability models, RMA outcomes, and hardware evaluations into a team knowledge base.\nParticipate in on-call rotations and incident response for hardware-related issues in the Memphis data center \nBASIC QUALIFICATIONS:\nBachelor's degree in Systems Engineering, Electrical Engineering, Computer Science, or a related field (or equivalent experience).\n2+ years of experience in hardware reliability engineering, preferably in high-performance computing or data center environments.\nProven expertise in firmware analysis, hardware specifications review, and release validation.\nStrong experience with RMA processes, including filing claims, vendor negotiations, and pushing for resolutions outside standard protocols.\nDemonstrated ability to diagnose and prove complex hardware failures, including grey or intermittent issues, using tools, logic analyzers, or diagnostic software.\nFamiliarity with data center hardware components (e.g., servers, GPUs, networking equipment) and emerging technologies.\nProficiency in scripting (Python, Bash) for automation and analysis, plus general experience in at least one systems language (C, C++, Java, Rust, or similar). Not required to be expert in all of them.\nExcellent problem-solving skills with a data-driven approach to reliability engineering.\nAbility to work collaboratively with cross-functional teams, including operations technicians.\nPREFERRED SKILLS AND EXPERIENCE:\nExperience in AI/ML infrastructure or supercomputing environments.\nKnowledge of vendor ecosystems (e.g., NVIDIA, Dell, HP, Supermicro) and supply chain management.\nCertifications in hardware engineering or reliability (e.g., CRE, CompTIA Server+).\nPrior work in a fast-paced startup or tech company like SpaceXSI.\nSpaceXSI is an equal opportunity employer.
