Our platform is used by frontier labs, Fortune 500 companies, and startups. We’ve raised $16M from top VCs and were YC W25.\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 from Blue Shield of CA (US employees)\n\nLunch and dinner when you’re in the office (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)\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\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":4992,"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"}],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-16T22:55:12Z"}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":7,"expected_fill_days":30,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-09-24T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/hud-senior-software-engineer-infrastructure","json_url":"https://alion.io/job/hud-senior-software-engineer-infrastructure.json","meta":{"generated_at":"2026-09-24T06:30:22Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers"}}
