We want data to be valuable for the people who create it and trustworthy for the labs that train on it. Our team is a quickly growing group of researchers, engineers and operators building the economy that shapes what AI will become. Backed by $16M from top VCs and YC (W25), our marketplace and platform are used by startups, Fortune 500 companies and frontier labs.\nAbout the role\nWe’re looking for a Senior Research Infrastructure Engineer to accelerate research on training and evaluating frontier AI agents. You’ll build the software and infrastructure that enable HUD’s researchers to iterate on environments, collect trajectories, and evaluate model behavior.\nYou’ll work closely with research engineers to understand the questions they’re investigating, identify bottlenecks in experimentation, and turn research code into reliable, reusable systems. You’ll own the tools, pipelines, and execution infrastructure that help researchers explore ideas, reproduce results, and scale promising approaches.\nResponsibilities\nBuild infrastructure that supports research on agent behavior through reliable environment execution, trajectory collection, and evaluation at scale\n\nDevelop reusable tools, APIs, and pipelines that let researchers launch experiments, manage datasets and configurations, and inspect trajectories and evaluation results\n\nTurn research prototypes and experimental workflows into tested, documented software that researchers can reuse and extend\n\nDesign experiments to understand model behavior, agent failure modes, and data quality issues\n\nMake experimentation faster, more reproducible, and more cost-efficient by improving orchestration, observability, and recovery from failed runs\n\nPartner with research and engineering to translate evolving research needs into infrastructure priorities and architecture decisions, owning systems from implementation through ongoing operation\n\nExperience\nYou may be a good fit if you have:\nStrong software engineering fundamentals and proficiency in Python, with a record of building maintainable systems used by others\n\nOwnership of backend services, data pipelines, developer tools, or infrastructure from design through deployment and operation\n\nSound judgment about APIs, data models, asynchronous workloads, and the tradeoffs involved in building reliable systems\n\nComfort with Docker, Linux, cloud infrastructure, and debugging failures across application code and the systems it runs on\n\nThe ability to work closely with researchers, understand experimental workflows, and translate open-ended research needs into useful software\n\nIndependent technical judgment to set priorities, make pragmatic architecture decisions, and improve systems as their users and workloads grow\n\nStrong candidates may also have:\nWorking knowledge of reinforcement learning, including environments, rollouts, reward signals, and evaluation workflows\n\nExperience building research infrastructure, ML pipelines, or tools that made a research team faster\n\nFamiliarity with distributed job execution, containerized environments, or high-concurrency workloads\n\nA track record of improving experiment reproducibility, data lineage, or visibility into complex pipeline failures\n\nWe prioritize technical aptitude and learning potential over years of experience. Motivated candidates are encouraged to apply even if they don't meet all criteria.\nTeam & company details\nTeam Size: ~25 people currently, mostly full-time in-person, but some remote.\n\nOur team: Our team includes 4 International Olympiad medalists (IOI, ILO, IPhO), the former #1 ranked Catan player in the world, serial AI startup founders, and researchers with publications at ICLR, NeurIPS, etc.\n\nCompany stage: We have 8 figures in funding and are scaling profitably and quickly to meet very strong demand.\n\nLogistics\nEmployment: Full-time.\n\nLocation: We have offices in San Francisco or Singapore but are open to remote candidates who can work hours that 70-80% overlap with either San Francisco or Singapore time zones.\n\nVisa Sponsorship: We provide support for relocation and visas for strong full-time candidates to the US or Singapore.\n\nTimeline: Applications are rolling. The process is 2 technical interviews and a 2-3 day work trial.\n\nWhat we offer\nCompetitive compensation\n\n100% covered top-of-the-line medical, dental, and vision (US and Singapore employees)\n\nLunch and dinner for in-office employees\n\nCompany-wide holiday break (Christmas Eve to New Year’s Day) on top of PTO and paid holidays\n\n401k with a 4% match\n\nOther perks including an Equinox membership and commuter benefits (US employees) and a health/wellness stipend (Singapore employees)\n\nUnlimited* access to tokens for ChatGPT, Claude Code, Cursor, etc. *By unlimited, we mean no one on our token usage leaderboard has ever hit a limit. So we have no idea what the limit is.\n\nTwo top-floor offices in San Francisco’s Union Square and Singapore’s Raffles Place\n\nAnnual travel budget to visit either office\n\nCompensation\nActual offers are adjusted for experience and location, but our base salary bands are\nSan Francisco (and other major US cities): $175,000 - $260,000\n\nSingapore: $130,000 - $195,000\n\nRest of world: $105,000 - $195,000\n\nDue to high volume, we may not actively respond to every application, but feel free to contact us at  or elsewhere if we missed your application!","description_format":"text","description_chars":5469,"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":["401k plan"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Singapore","iso":"SG","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["AI Training Data & Annotation","Data Marketplaces, Sharing & Clean Rooms"],"lifecycle":[{"event":"open","at":"2026-10-23T23:07:17Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":36,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/hud-senior-research-infrastructure-engineer","json_url":"https://alion.io/job/hud-senior-research-infrastructure-engineer.json","meta":{"generated_at":"2026-10-25T19:33:24Z","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":27785,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":678875},"rest":"https://alion.io/mcp/rest/get_company?id=678875"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhud-senior-research-infrastructure-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%2Fhud-senior-research-infrastructure-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%2Fhud-senior-research-infrastructure-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/hud-senior-research-infrastructure-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhud-senior-research-infrastructure-engineer"}]}
