We are a group of engineers, scientists, roboticists, and company builders developing foundation models and learning algorithms to power the robots of today and the physically-actuated devices of the future.\nThe Team\nYou will work alongside the researchers and engineers bringing general-purpose AI into the physical world. We value pragmatism, initiative, and people who enjoy solving problems together. You will have the autonomy to identify what matters most and see improvements through.\nAbout the Role\nYou will secure the models, data, infrastructure, and compute that power Physical Intelligence. This is a hands-on role for someone who likes digging into systems and building reliable tools that help researchers and engineers work securely at speed. You will prioritize the biggest risks and build practical protections that keep pace with how we work.\nIn This Role You Will\nBuild and operate systems that protect our models, data, and compute.\n\nPartner with researchers and engineers on architecture and development workflows.\n\nAutomate access management, infrastructure safeguards, and software delivery checks.\n\nWrite production-quality tools and contribute fixes directly to engineering repositories.\n\nFind and exploit vulnerabilities, assess their impact, and validate fixes with system owners.\n\nSet security priorities and bring in outside expertise where needed.\n\nWhat We Hope You’ll Bring\nStrong programming skills in Python, Go, or similar languages, including reviewing unfamiliar code and shipping maintainable software.\n\nA track record of partnering with engineering teams to solve problems from discovery through rollout.\n\nExperience operating and securing cloud infrastructure, including Linux, IAM, networking, containers, or CI/CD.\n\nConnections in the security community and curiosity about emerging threats and techniques.\n\nHands-on offensive security experience and sound judgment about real-world risk.\n\nBonus Points\nExperience securing AI/ML infrastructure or agent execution environments.\n\nExperience building detection systems or helping establish a security function.\n\nExcitement about robotics and a desire to learn.\n\nPursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.","description_format":"text","description_chars":2380,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Foundation Models","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-10-23T22:06:30Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":2,"expected_fill_days":55,"reasons":["conf:2","stale_co","velocity","win:early"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/physical-intelligence-lead-security-engineer","json_url":"https://alion.io/job/physical-intelligence-lead-security-engineer.json","meta":{"generated_at":"2026-10-26T10:28:26Z","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":14018,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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":48436},"rest":"https://alion.io/mcp/rest/get_company?id=48436"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fphysical-intelligence-lead-security-engineer"},{"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%2Fphysical-intelligence-lead-security-engineer"},{"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%2Fphysical-intelligence-lead-security-engineer"},{"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/physical-intelligence-lead-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fphysical-intelligence-lead-security-engineer"}]}
