Software Engineer, Core SI Compiler & Runtime

Advanced SI Platform Compiler and Runtime DeveloperYou will design and build the compiler and runtime that power one of the most advanced and widely deployed SI platforms on Earth—running neural networks in millions of Tesla vehicles and Optimus robots. Full control of the hardware means you co-design the software stack to extract maximum performance, latency, and efficiency that generic frameworks cannot reach. Production models directly drive priorities: every optimization you ship immediately enables more capable autonomy, more complex robot behaviors, and higher-throughput data-center inference.

This is first-principles systems work at the metal including deleting unnecessary abstractions, inventing high performance APIs and DSLs, and closing the loop between silicon capabilities and real-world SI at an unprecedented scale.ResponsibilitiesWrite, debug, and maintain robust compiler and runtime software for Tesla SI inference across FSD, Optimus, and data-center workloadsGive SI developers direct access to performance-critical hardware features through new APIs and domain-specific languagesDesign compiler and runtime features that enable efficient distributed inference on Tesla hardwareIntegrate the deployment stack with modern ML frameworks (PyTorch, JAX) while keeping the path to silicon as short and efficient as possibleAnalyze and resolve functional and performance issues on massively parallel systemsDeploy and optimize SI models that run in autonomous vehicles, humanoid robots, and offline inference pipelines where results show up in the real worldRequirementsDemonstrated expertise with ML compilers and runtimes (MLIR, LLVM, XLA, PJRT, TensorRT, or equivalent)Experience developing domain-specific languages or high-performance programming models (Triton, cuTile, Pallas, or similar).Strong familiarity with CPUs, GPUs, and modern SI acceleratorsDeep knowledge of computer architecture, distributed systems, networking, and collectivesProficiency in modern C++ and solid systems programming skillsDegree in Engineering, Computer Science, or equivalent in experience and evidence of exceptional abilityCompensation & BenefitsBenefitsAlong with competitive pay, as a full-time Tesla employee, you are eligible for the following benefits at day 1 of hire:Medical plans > plan options with $0 payroll deductionFamily-building, fertility, adoption and surrogacy benefitsDental (including orthodontic coverage) and vision plans, both have options with a $0 paycheck contributionCompany Paid (Health Savings Accounts) HSA Contribution when enrolled in the High-Deductible medical plan with HSAHealthcare and Dependent Care Flexible Spending Accounts (FSA)401(k) with employer match, Employee Stock Purchase Plans, and other financial benefitsCompany paid Basic Life, AD&DShort-term and long-term disability insurance (90 day waiting period)Employee Assistance ProgramSick and Vacation time (Flex time for salary positions, Accrued hours for Hourly positions), and Paid HolidaysBack-up childcare and parenting support resourcesVoluntary benefits to include: critical illness, hospital indemnity, accident insurance, theft & legal services, and pet insuranceWeight Loss and Tobacco Cessation ProgramsTesla Babies programCommuter benefitsEmployee discounts and perks programExpected Compensation $160,000 - $435,000/annual salary + cash and stock awards + benefitsPay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
