ASI may be developed in the next few years, but it is unclear whether alignment is on track to be ready in the same timeframe. We aim at higher a priori confidence in aligned outcomes by pursuing a portfolio of theory and empirics bets, any one of which, if it succeeds, would meaningfully advance the field. We invest heavily in research automation to accelerate progress, and we believe that stronger alignment theory unlocks higher automation: more principled approaches give us better filters for which directions of automated research are promising.\nResolution was founded in 2026 by researchers from UK AISI's Alignment Team, who ran the £30m Alignment Project, and Timaeus, who pioneered applying singular learning theory to alignment.\nFor more information, see our announcement.\nAbout the Team\nMany teams at Resolution make use of Lean to accelerate their research, including Learning Theory (see our recent autoformalization of Hironaka’s Resolution of Singularities), Scalable Oversight (which is aiming for things like formal guarantees and impossibility results over debate protocols), and Agent Foundations (which is formalizing results on feedback, fixed points, and previsions in Lean).\nAlthough these projects operate independently, they share a need for knowledge, infrastructure, tools, and wisdom for doing theory research with Lean. You would be the first person to drive this initiative. This means working closely with researchers and engineers in our research divisions, as well as with engineers in central engineering and automation roles.\nAbout the Role\nYou would be responsible for making Resolution good at Lean at scale.\nAt the highest level, this means providing taste and expertise in Lean and autoformalization. Resolution already houses several Lean users, but none of us are experts. So far we’ve gotten by on using AI agents to write Lean for us and on our general mathematics and software-engineering judgment. But this is not enough as our Lean efforts continue to grow. We are looking for someone who can guide us in our Lean usage and think strategically about what structures to build to make the various org autoformalization efforts go better. This will let us accelerate our theoretical research efforts, especially as we hand off more and more research to AI agents.\nImportantly, this role does not mean you will be writing Lean. Agents will continue to write almost all of our Lean and will be the primary consumers of the Lean we produce. The volume of Lean will be larger than any human can individually interpret. Your job is to make this reliable and effective at that scale: set the conventions, architecture, and review structures that let researchers set the right definitions and trust agent output without reading every proof.\nResponsibilities\nNurture Lean wisdom throughout the organization and be a champion of Lean and autoformalization.\n\nBuild and maintain the structures so we can trust agent autoformalization outputs: proof harnesses, code review workflows, etc.\n\nBuild and maintain shared Lean libraries with clear definitions, useful abstractions, and a structure that supports review and further (automated) research.\n\nConsolidate overlapping formalizations, resolve inconsistent definitions, and build shared foundations for researchers and agents to reuse.\n\nImprove the reliability, maintainability, and performance of shared Lean projects.\n\nSupport researchers in developing custom tools, tactics, and workflows to help them make progress.\n\nImplicit in all of these responsibilities is the understanding that this will be heavily AI-assisted.\nYou May Be a Good Fit If You\nHave several years of experience writing Lean and mathlib.\n\nHave expertise in Lean community practices (so you can, e.g., explain why one definition, abstraction, or library design works better than another).\n\nAre an AI power user and have experience with autoformalization, and plan to (eventually) never write another line of Lean by hand.\n\nCommunicate clearly and enjoy working closely with researchers and engineers.\n\nHave a strong mathematics or theoretical computer science background (Bachelor’s at minimum).\n\nWant to contribute to the alignment of artificial superintelligence.\n\nStrong Candidates May Also Have\nContributions to mathlib or other substantial Lean libraries.\n\nExperience designing or maintaining large formalization projects.\n\nExperience with Lean tooling, tactic development, metaprogramming, or proof automation.\n\nExperience with AI-assisted mathematical research or automated evaluation.\n\nApplication Process\nAfter application review, our process includes:\nScreening Call (30 minutes): discuss your background, motivation, and Lean experience.\n\nExperience Interview (1 hour): examine past projects, your contributions, as well as mathematical and library design choices.\n\n[Optional] Live Technical/Work test: may end up being skipped; details to be determined.\n\nIndividual conversations with Geoffrey and other team members (30 minutes each): discuss the work, your experience, and how we could work together.\n\nWe will share the format before each interview. Each conversation includes time for your questions.\nLogistics\nThis is a full-time role based in Berkeley, California. Remote work may be considered in exceptional cases. We can sponsor visas for relocation to Berkeley.\nCurrent Research Engineer salary levels are:\nL4: $208,000 remote, $346,000 in person.\n\nL5: $270,000 remote, $451,000 in person.\n\nL6: $402,000 remote, $670,000 in person.\n\nL7: $558,000 remote, $930,000 in person.\n\nBenefits include five weeks of paid vacation plus public holidays, comprehensive medical, dental, and vision insurance, unlimited sick leave, and an unconditional 401(k) contribution equal to 4% of salary.\nMinimum education: a relevant bachelor's degree.\nApplications are reviewed on a rolling basis. Start date: as soon as practical.","description_format":"text","description_chars":5983,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Vision insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Artificial Intelligence","AI Safety & Alignment"],"lifecycle":[{"event":"open","at":"2026-10-06T04:45:00Z"}],"visa":[],"liveness":{"score":83,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.832,"p_room":1,"age_days":6,"expected_fill_days":20,"reasons":["conf:1","win:early"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/resolution-lean-engineer","json_url":"https://alion.io/job/resolution-lean-engineer.json","meta":{"generated_at":"2026-10-13T00:36:01Z","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":977,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":2177261},"rest":"https://alion.io/mcp/rest/get_company?id=2177261"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fresolution-lean-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%2Fresolution-lean-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%2Fresolution-lean-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/resolution-lean-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fresolution-lean-engineer"}]}
