Software Engineer, Onboard Diagnostics

Software EngineerWe are seeking a Software Engineer to build and own the diagnostic software that runs on our vehicles. You will develop the in-house frameworks at the core of vehicle diagnostics, including our Diagnostic Event Manager (DEM), the per-ECU process responsible for monitoring fault conditions and triggering Diagnostic Trouble Codes (DTCs). You will also support homologation teams in meeting evolving diagnostic and regulatory requirements worldwide.

This role spans embedded firmware, diagnostic protocols, and compliance, and requires close collaboration across hardware, software, and service teams.ResponsibilitiesDevelop and extend the Diagnostic Event Manager and DTC stack across vehicle controllers, defining how faults are detected, debounced, persisted to non-volatile memory, and reported over standard protocols such as UDS, CAN, and DoIPIntegrate the diagnostic framework across a range of controllers, embedded targets, and vehicle platforms, and manage versioned updates to these shared components in lockstepWork with homologation teams to translate evolving diagnostic and regulatory requirements into actionable engineering work, and support certification and reporting activitiesBuild test infrastructure (e.g., SIL/HIL) that validates DEM and DTC behavior consistently across controllers and platformsDevelop diagnostic tooling and service routines that help technicians accurately identify and clear faults in the fieldMonitor fleet-wide diagnostic data to track DTC trigger rates, and build dashboards that surface trends, catch regressions, and feed top field issues back to development teamsCollaborate with cross-functional teams to refine internal processes, streamline development, and drive on-time product releasesDocument technical procedures and create guidelines that enhance collaboration and knowledge transferRequirementsDegree in Computer Science, Electrical Engineering, Automotive Engineering, or related field, or equivalent experienceProficiency in C/C++ or similar languages for embedded firmware developmentExperience with automotive communication networks and diagnostic protocols (CAN, LIN, UDS, DoIP) for system development, validation, and troubleshootingExperience developing across heterogeneous embedded targets and multiple vehicle platformsFamiliarity with diagnostic standards and concepts (e.g., DTCs, SAE J1979, ISO 13400)Strong organizational skills to manage multiple timelines, prepare accurate documentation, and address auditsExcellent communication skills for coordination with cross-functional teams and, where needed, regulatory and industry bodiesProven background in automotive diagnostics, including hands-on development of embedded diagnostic software, is a plusFamiliarity with global OBD regulations and certification processes is a plusCompensation & 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 $140,000 - $252,000/annual salary + cash and stock awards + benefitsPay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
