Since its start as the Google Self-Driving Car Project in 2009, Waymo has focused on building the Waymo Driver-The World's Most Experienced Driver™-to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states.\nThe Onboard Software Performance team ensures that systems running on our Waymo's meet strict performance requirements such as producing necessary outputs within strict latency targets and using the allocated amount of compute resources (CPU/GPU/TPU/RAM) for each respective submodule. All of this needs to be done at scale with performance guarantees of many 9s of reliability while promoting high velocity of system evolution.\nYou will:\nDevelop ADV's modular architecture improvements and frameworks that maximize performance and compute use and ROI for driving quality\nEvolve our compute usage on the car and simulation to promote continued scaling where the system runs fast on the car and in our data center\nCollaborate with onboard teams to identify and improve compute performance bottlenecks across the stack to improve performance/driving quality\nCollaborate with hardware teams to codesign hardware/software and improve the software for best performance on our hardware platform\nEnsure reaction latency for collision avoidance with and help design novel system/architecture for extremely fast nominal performance\nDevelop necessary high scale performance evaluation, debugging and software change management processes\nImprove system resource usage to simulation at scale in Cloud datacenters: minimizing CPU use and latency, minimizing RAM usage, intelligently determining which computations should happen on CPU, GPU, and TPU.\nYou have:\nBS in Comp Sci, EE, Robotics, Physics, Math, or related field (or equivalent experience)\n3 years of experience as a software engineer or similar roles\n3 years of experience in C++\n3 year of experience optimizing software using profile guided techniques\nWe prefer:\n2 years in infrastructure/systems/performance domain optimizing end-to-end systems\n2 years of experience working on a large-scale/high complexity system (supported by hundreds of engineers)\nExperience in robotics\nExperience in low-level optimization techniques, frameworks (SIMD/CUDA) and ML performance/frameworks\nExperience in evaluation techniques\nThis is a hybrid remote/in-office role.\nThe expected base salary range for this full-time position across US locations is listed below. Actual starting pay will be based on job-related factors, including exact work location, experience, relevant training and education, and skill level. Your recruiter can share more about the specific salary range for the role location or, if the role can be performed remote, the specific salary range for your preferred location, during the hiring process. \nWaymo employees are also eligible to participate in Waymo’s discretionary annual bonus program, equity incentive plan, and generous Company benefits program, subject to eligibility requirements. \nSalary Range\n$175,000—$215,000 USD","description_format":"text","description_chars":3488,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Autonomous Driving","Smart Mobility","Ride Hailing"],"lifecycle":[{"event":"open","at":"2026-10-27T01:33:16Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 331 · green card filings: 28","filings_12m":331,"filings_prev_12m":227,"green_card_filings_12m":28,"median_offered_wage_usd":206330,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":234}],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.378,"p_room":0.28,"age_days":350,"expected_fill_days":79,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-27T05:46:45Z"},"pay":{"stated_usd_annual":215000,"is_top_pay":true},"html_url":"https://alion.io/job/waymo-onboard-software-performance-engineer-c","json_url":"https://alion.io/job/waymo-onboard-software-performance-engineer-c.json","meta":{"generated_at":"2026-10-28T01:13:54Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1497,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":98},"rest":"https://alion.io/mcp/rest/get_company?id=98"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwaymo-onboard-software-performance-engineer-c"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fwaymo-onboard-software-performance-engineer-c"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fwaymo-onboard-software-performance-engineer-c"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/waymo-onboard-software-performance-engineer-c\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwaymo-onboard-software-performance-engineer-c"}]}
