While most AI makes maximum-likelihood guesses, Harmonic's Aristotle uses Lean4 and reinforcement learning to verify its reasoning and results.\nFollowing our Gold Medal-level performance on the 2025 International Math Olympiad (IMO) and the successful resolution of long-standing open problems, we are proving that AI can master the most rigorous domains of human thought. Backed by some of the world’s most prominent investors, we are intentionally scaling an elite technical team.\nVisit ourcompany blogto learn more about what we are working on!\nAbout the Role\nWe are seeking a highly motivated and skilled Research Engineer to join our Reinforcement Learning & Formal Methods team. This position will be focused on advancing mathematical theorem proving using cutting-edge RL techniques. The successful candidate will play a key role in developing new algorithms and models that integrate RL with formal methods to solve complex problems in theorem proving and beyond.\nKey Responsibilities\nConduct high-quality research in the intersection of RL and formal methods, with a focus on mathematical theorem proving.\n\nDevelop and implement novel RL algorithms and models for theorem proving.\n\nCollaborate with a multidisciplinary team to integrate RL techniques with formal methods.\n\nStay abreast of the latest developments in RL, formal methods, and related fields.\n\nMinimum Qualifications\nBS or MS in Computer Science, Mathematics a related technical field, or equivalent industry experience\n\nStrong programming skills in Python, with experience in software development and testing.\n\nExperience in deep learning frameworks such as PyTorch\n\nStrong understanding of mathematical concepts, including algebra, geometry, and analysis.\n\nPreferred Qualifications\nPhD in Computer Science, Mathematics, or a related field.\n\nExperience in applying AI to solve practical problems in formal methods.\n\nProven track record of high-quality research demonstrated by publications, patents, or software contributions.\n\nContributions to open-source projects or development of software tools in the field.\n\nStrong background in RL, particularly in areas relevant to theorem proving (e.g., machine learning, natural language processing).\n\nProficiency in formal methods, including experience with theorem proving systems.\n\nWhat We Offer\nUnlimited PTO\n\n401(k) matching\n\n100% employer-paid health, vision, and dental benefits for employees and 50% coverage for dependents. Harmonic offers varied health coverage options to select what is best for you and your family.\n\nHealth Savings Account (HSA) available for qualifying health plans\n\nEqual Opportunity Statement\nHarmonic is committed to diversity and inclusivity in the workplace. We are an equal opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or any other legally protected status.","description_format":"text","description_chars":3033,"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":["Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI for Science"],"lifecycle":[{"event":"open","at":"2025-07-10T15:54:43Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.12,"p_room":0.28,"age_days":463,"expected_fill_days":22,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":450000,"is_top_pay":true},"html_url":"https://alion.io/job/harmonic-research-engineer","json_url":"https://alion.io/job/harmonic-research-engineer.json","meta":{"generated_at":"2026-10-17T06:42:28Z","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":9150,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":48286},"rest":"https://alion.io/mcp/rest/get_company?id=48286"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fharmonic-research-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%2Fharmonic-research-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%2Fharmonic-research-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/harmonic-research-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmonic-research-engineer"}]}
