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.\nSoftware Engineering builds the brains of Waymo's fully autonomous driving technology. Our software allows the Waymo Driver to perceive the world around it, make the right decision for every situation, and deliver people safely to their destinations. We think deeply and solve complex technical challenges in areas like robotics, perception, decision-making and deep learning, while collaborating with hardware and systems engineers. If you’re a software engineer or researcher who’s curious and passionate about Level 4 autonomous driving, we'd like to meet you. \nThe Onboard Software team develops the critical software and machine learning models that power the Waymo Driver. Our systems enable the vehicle to perceive its surroundings, make safe driving decisions, and transport people to their destinations. With Waymo's fleet driving millions of miles every week, we operate at a scale that exposes our technology to a vast array of challenging real-world scenarios.\nAs Principal Software Engineer Post Training, you will play a key role in advancing the technology to power the Waymo Driver and especially help it scale to dramatically more miles and locations across the world. Your primary responsibility will be to develop and lead a strategy of a next-generation post-training system on top of existing large-scale models (whose development this role will also influence). Post training is already used in the onboard software system, but we believe that there is a significant opportunity to advance its impact, in line with the advancements within the AI community in other applications. Your role would be to figure out how to accomplish that goal in the challenging, highly impactful problem of autonomously driving a vehicle in the real world at large scale.\nThis role follows a hybrid work schedule and reports into the Onboard organization.\nYou will:\nAdvance the state-of-the-art post-training techniques in the AI running on board the autonomous vehicle\nKeep up with post-training research and find the right applications for the unique problems at Waymo\nParticipate in the leadership community advancing the ML stack across Waymo in general\nPartner with teams developing ML platforms to develop them for effective, scalable post-training\nPartner with teams not yet using post-training effectively to understand their needs and guide them to effective post-training strategies\nYou have:\nMS in computer science with an emphasis in machine learning or equivalent degree (PhD preferred)\n10+ years of leadership experience in a large-scale machine learned production system\nExperience leading a post-training system that is used in production with 100M+ users, solving multiple targeted problems in parallel\nExperience building metrics, data, and flywheels for post-training applications\nExperience influencing without authority at the director and VP level or higher\nAn ability to balance influencing day-to-day leadership on the ground with developing and influencing engineering strategy\nWe prefer:\nExperience building a post-training platform from scratch\nExperience with utilizing ML in AV and/or other robotics applications\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$349,000—$431,000 USD","description_format":"text","description_chars":4531,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Hybrid work"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-13T01:49:48Z"}],"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":56,"band":"ok","label":"Likely open","p_open":1,"p_active":0.775,"p_room":0.72,"age_days":51,"expected_fill_days":76,"reasons":["conf:3","velocity","win:mid","crowd:brand"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":431000,"is_top_pay":true},"html_url":"https://alion.io/job/waymo-principal-software-engineer-post-training-2","json_url":"https://alion.io/job/waymo-principal-software-engineer-post-training-2.json","meta":{"generated_at":"2026-10-15T13:02:54Z","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":20066,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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-principal-software-engineer-post-training-2"},{"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-principal-software-engineer-post-training-2"},{"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-principal-software-engineer-post-training-2"},{"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-principal-software-engineer-post-training-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwaymo-principal-software-engineer-post-training-2"}]}
