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 Software Engineer, Infrastructure who can own the reliability, scale, performance, and developer experience of HUD’s core infrastructure and backend systems.\nThis is not a pure infrastructure role. The right person has strong production infra experience, but also thinks like a backend engineer: they can reason about service architecture, queues, databases, APIs, deployment safety, performance bottlenecks, and how product requirements translate into resilient systems. You’ll work across AWS, Kubernetes, Terraform, CI/CD, observability, and backend services to make HUD faster, more reliable, cheaper to run, and easier for engineers to build on.\nResponsibilities\nOwn production uptime, latency, provisioning speed, infrastructure cost, and incident response for core platform services\n\nBuild and maintain AWS infrastructure with Terraform, Kubernetes/EKS, Helm, Docker, EC2, CodeBuild, ECR, S3, IAM, networking, and secrets management\n\nDesign and improve backend and platform systems for scale, including capacity planning, autoscaling, queueing, backpressure, cleanup jobs, retries, and rollback paths\n\nDefine and improve dashboards, alerts, logs, traces, SLOs, runbooks, and on-call workflows so failures are detected, debugged, and resolved quickly\n\nBuild reliable CI/CD, release automation, environment management, and deployment workflows that improve developer productivity and reduce production risk\n\nWrite clean, maintainable code where needed to automate systems, improve backend services, and create internal tooling\n\nExperience\nYou may be a good fit if you:\nHave owned production cloud infrastructure for a high-availability, user-facing platform, with responsibility for uptime, performance, deployment safety, and cost\n\nHave deep experience with AWS infrastructure and containerized systems; experience with tools like Terraform, Kubernetes/EKS, Docker, EC2, CodeBuild, ECR, S3, IAM, load balancers, networking, and secrets management is strongly preferred\n\nHave built or operated CI/CD, environment management, release automation, observability, alerting, and incident response systems\n\nHave strong backend engineering judgment and can reason about service architecture, APIs, databases, async systems, queues, scaling limits, and production failure modes\n\nCan write clean, maintainable code and apply strong software engineering judgment across product architecture, infrastructure, backend systems, and developer workflows\n\nStrong candidates may also have:\nExperience operating infrastructure for data-heavy, ML/AI, workflow, marketplace, developer-tools, or enterprise platforms\n\nExperience designing systems for bursty workloads, long-running jobs, sandboxed execution, distributed workers, or high-concurrency services\n\nExperience reducing cloud spend through better architecture, autoscaling, workload placement, caching, cleanup systems, or observability\n\nExperience building internal platforms or tools that make engineers faster without hiding too much complexity\n\nWe prioritize technical aptitude, ownership, and learning potential over years of experience.\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), 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\nOther perks including an Equinox membership, 401k, 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 [[email removed]](mailto:[email removed]) or elsewhere if we missed your application!","description_format":"text","description_chars":5547,"description_truncated":false,"requirements":{"experience_years_min":3,"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":["Artificial Intelligence","Cybersecurity","Incident Response"],"lifecycle":[{"event":"open","at":"2026-10-25T07:54:30Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":35,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":260000,"is_top_pay":true},"html_url":"https://alion.io/job/rl-list-senior-software-engineer-infrastructure","json_url":"https://alion.io/job/rl-list-senior-software-engineer-infrastructure.json","meta":{"generated_at":"2026-10-30T21:39:19Z","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":12158,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":2804891},"rest":"https://alion.io/mcp/rest/get_company?id=2804891"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frl-list-senior-software-engineer-infrastructure"},{"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%2Frl-list-senior-software-engineer-infrastructure"},{"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%2Frl-list-senior-software-engineer-infrastructure"},{"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/rl-list-senior-software-engineer-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frl-list-senior-software-engineer-infrastructure"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3230166}},{"tool":"search_jobs","arguments":{"company":"rl-list.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3230166},"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.
