We eliminate the risk and improve the reliability of LLM apps by haizing them -- i.e. rigorously, proactively, and continuously fuzz-testing them.\nWe are looking for Software Engineering Interns to help develop our reliability platform, with a focus on:\nData-efficient alignment of evaluation models\nDynamic testing of AI applications\nObservability and anomaly detection \nDiscrete optimization (with applications in architecture search and automated prompting)\nOur work is both intellectually stimulating and practically useful. Your work will result in net-new primitives, frameworks, and algorithms for developing robust LLM applications. You work will directly influence how LLM apps are tested, verified, and deployed everywhere. \nAnnual Salary\n$100,000 - $125,000 USD\nResponsibilities\nWork directly with customers to adapt our core R&D for different domains.\nBuild out core infra, cloud tooling, and UX around our algorithms.\nShip delightful tools that are used by AI application developers all across the world. \nQualifications\nHigh-agency, customer-centric full-stack experience, e.g. ex-founder or ex-founding engineer.\nStrong open source presence or strong track record of software engineering projects and employment.\nExperience with ML in an applied setting.\nCan ramp up quickly to understand our research.\nLogistics\nLocation policy: In NYC.\nUS visa sponsorship: If you are exceptional, we will sponsor.\nCompensation and Benefits: We provide generous salary, equity, and benefits\nWe're Not Here to Play Games.\nWe're not here to write GPT wrappers or get rich quick off the AI bubble. We're here to solve the hardest problem in AI: making it safe, reliable, and production-ready. \nSince our company's inception in 2024, we've amassed amazing customers like OpenAI, Anthropic, AI21, and several others. We've developed best-in-class tooling for evaluation, dynamic testing, red-teaming, observability, and continuous robustification. And we’re backed + advised by the founders of Cognition, Hugging Face, Weights and Biases, Nous, Etched, Okta, Replit and C-suite execs from Google, Stripe, Databricks, Robinhood, and more.\nOur core team is exceptionally fit for this mission. We turned down Stanford PhDs, got into & rejected Y Combinator, wrote ML-guided matchmaking for 50,000+ students, built an educational nonprofit supporting 60 countries, and did some other cool things along the way. Our early hires include an MIT PhD with 21,000+ Physics/ML/Stats citations, a Datadog engineering manager who led their GenAI observability team, a Citadel quant with a huge open-source presence, and more.\nWe can only serve our mission with an incredibly high talent-density team. Come here to push yourself, learn fast, experience excellence, grow with each other, and pursue your life's work.","description_format":"text","description_chars":2854,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-13T20:21:57Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":1,"p_active":0.097,"p_room":0.28,"age_days":516,"expected_fill_days":22,"reasons":["conf:2","win:tail","crowd:junior"],"computed_at":"2026-10-14T06:34:16Z"},"pay":{"stated_usd_annual":125000,"is_top_pay":true},"html_url":"https://alion.io/job/haizelabs-software-engineer-intern","json_url":"https://alion.io/job/haizelabs-software-engineer-intern.json","meta":{"generated_at":"2026-10-14T11:17:45Z","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":13457,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":1990629},"rest":"https://alion.io/mcp/rest/get_company?id=1990629"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhaizelabs-software-engineer-intern"},{"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%2Fhaizelabs-software-engineer-intern"},{"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%2Fhaizelabs-software-engineer-intern"},{"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/haizelabs-software-engineer-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhaizelabs-software-engineer-intern"}]}
