Our products are used by leading businesses in sales, marketing, insurance, and coding to build best-in-class AI agents with flexible and powerful programmatic access to the web.\nWe've raised $230 million from Kleiner Perkins, Sequoia, Index Ventures, Spark Capital, Khosla Ventures, First Round, and Terrain to build the web for AIs. We're currently valued at $2 billion and we're forming a world-class team of engineers, designers, marketers, sellers, researchers, and operational experts to achieve our mission.\nAbout you\nYou're a researcher who thinks like an engineer, or an engineer who thinks like a researcher. You've worked on information retrieval systems, embedding models, or neural ranking at scale, or you're deeply curious about the fundamental problems that emerge when training models to understand and serve billions of web documents. You thrive in the space between theory and production, where elegant solutions must also run efficiently on real infrastructure. You're comfortable reading papers from SIGIR and RecSys one day and debugging distributed training pipelines the next.\nThe role\nYou'll design and train the models that power Parallel's APIs: the intelligence layer that helps AI agents find exactly what they need from the open web. This means tackling research problems that most labs encounter only at hyperscale: How do you train embedding models that capture semantic intent across diverse query types? How do you balance model expressiveness with sub-second retrieval latency? How do you maintain index freshness when the web updates constantly, without rebuilding from scratch?\nUnlike traditional search engines built for human queries, you're building for AI agents that issue complex, multi-hop queries and expect structured, programmatic responses. This is information retrieval reimagined for the LLM era, work that combines classical IR techniques with modern deep learning, applied at a scale that demands new solutions.\nYou might be a good fit if you have:\nBachelor's degree or equivalent combination of education, training, and professional experience\n\nA field relevant to the role as demonstrated through coursework, training, or professional experience\n\nYears of experience required will correlated with the internal job level requirements for this position\n\nLife at Parallel\nOur team works fully in-person, between our Palo Alto HQ and San Francisco office. We’re a flat, talent-dense organization dedicated to solving technical and creative problems.\nWe seek like-minded individuals who share our passion for applying science, creativity, and consistency to big and complex problems with equally big outcomes. These are our values:\nOwn customer impact: It’s on us to ensure real-world outcomes for our customers.\n\nObsess over craft: Perfect every detail because quality compounds.\n\nAccelerate change: Ship fast, adapt faster, and move frontier ideas into production.\n\nCreate win-wins: Creatively turn trade-offs into upside.\n\nMake high-conviction bets: Try and fail. But succeed an unfair amount.\n\nCompensation & benefits\nCompetitive salary\n\nGenerous equity\n\nVisa sponsorships\n\n401K plans\n\nDaily lunch & office snacks\n\nDinner at the office\n\nUnlimited vacation\n\nCaltrain pass reimbursement","description_format":"text","description_chars":3288,"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":["401k plan","Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","AI Search"],"lifecycle":[{"event":"open","at":"2026-01-24T16:20:49Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 10","filings_12m":10,"filings_prev_12m":6,"green_card_filings_12m":0,"median_offered_wage_usd":258500,"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)"],"filings_for_role_12m":7}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.288,"p_room":0.28,"age_days":271,"expected_fill_days":62,"reasons":["conf:1","win:tail","crowd:junior"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/parallel-early-career-research-engineer","json_url":"https://alion.io/job/parallel-early-career-research-engineer.json","meta":{"generated_at":"2026-10-24T00:20:17Z","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":495,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":25200},"rest":"https://alion.io/mcp/rest/get_company?id=25200"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fparallel-early-career-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%2Fparallel-early-career-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%2Fparallel-early-career-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/parallel-early-career-research-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fparallel-early-career-research-engineer"}]}
