Frontier AI labs and pharma companies use them to answer one question: can an agent handle the multilayered reasoning that biological work demands? Every benchmark is grounded in experimental and clinical work and built by scientists who have done that work themselves.\nThe Role\nYou will be working on problems in post-training, data quality, task and reward shaping, ML infrastructure, scientific benchmark design, and benchmark delivery. Challenges span understanding the intersection of biology and ML, collaborating directly with scientists, and maintaining quality at a fast cadence.\nHow we work\nOur engineering team is in-person in San Francisco. We look for driven engineers who are excited to take ownership on hard problems and ship creative, useful solutions\nLearn More About Us\nAbout Us · Website · Twitter · Blog\n\nHiring process\nOur process is typically completed within two weeks.\nRound 1: Introduction\nRound 2: Takehome Assessment\nRound 3: Technical\nRound 4: Final/ 3-Day Paid Onsite Project\nOffer","description_format":"text","description_chars":1133,"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":["Bioinformatics","Scientific & Lab Software"],"lifecycle":[{"event":"open","at":"2026-11-13T04:24:34Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":6,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 5","filings_12m":5,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":112500,"route":null,"cap_exempt":false,"checked_at":"2026-11-12T07:36:15+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","Alion: sponsorship offered in the employer's own job adverts (24 months)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":27,"reasons":["conf:3","win:early"],"computed_at":"2026-11-13T07:30:42Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/latchbio-research-engineer-biology","json_url":"https://alion.io/job/latchbio-research-engineer-biology.json","meta":{"generated_at":"2026-11-13T07:30:42Z","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":15642,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":171847},"rest":"https://alion.io/mcp/rest/get_company?id=171847"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flatchbio-research-engineer-biology"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Flatchbio-research-engineer-biology"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Flatchbio-research-engineer-biology"},{"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/latchbio-research-engineer-biology\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flatchbio-research-engineer-biology"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4220168}},{"tool":"search_jobs","arguments":{"company":"latch.bio","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4220168},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
