Job summary

HUD is hiring a Platform Engineer to own the reliability, scale, and developer experience of our core infrastructure. You will balance production infra with backend engineering, shaping service architecture, queues, databases, APIs, and safe deployments.

Expect deep work across AWS, Kubernetes, Terraform, CI/CD, observability, and backend services to improve speed, cost, and engineer productivity. Relocation and visa support available.

Qualifications

• Owned production cloud infrastructure for a high-availability platform.
• Deep AWS/container experience with Terraform, Kubernetes, Docker.
• Experience with CI/CD, observability, and incident response.

Responsibilities

• Own production uptime, latency, provisioning speed, and incident response.
• Build and maintain AWS infrastructure with Terraform, Kubernetes, Helm, Docker, and related tools.
• Design and improve backend/platform systems for scale and reliability.
• Define dashboards, alerts, logs, traces, and runbooks for rapid resolution.

Job description

About HUD

HUD is building infrastructure to create RL training data and evals for frontier AI agents, as well as a marketplace to sell these to frontier labs through the HUD marketplace. Our platform is used by frontier labs, Fortune 500 companies, and startups. We’ve raised $16M from top VCs and were YC W25.

About the role

We’re looking for a Platform Engineer who can own the reliability, scale, performance, and developer experience of HUD’s core infrastructure and backend systems.

This 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.

Responsibilities

• Own production uptime, latency, provisioning speed, infrastructure cost, and incident response for core platform services
• Build and maintain AWS infrastructure with Terraform, Kubernetes/EKS, Helm, Docker, EC2, CodeBuild, ECR, S3, IAM, networking, and secrets management
• Design and improve backend and platform systems for scale, including capacity planning, autoscaling, queueing, backpressure, cleanup jobs, retries, and rollback paths
• Define and improve dashboards, alerts, logs, traces, SLOs, runbooks, and on-call workflows so failures are detected, debugged, and resolved quickly
• Build reliable CI/CD, release automation, environment management, and deployment workflows that improve developer productivity and reduce production risk
• Write clean, maintainable code where needed to automate systems, improve backend services, and create internal tooling

Experience

You may be a good fit if you:

• Have owned production cloud infrastructure for a high-availability, user-facing platform, with responsibility for uptime, performance, deployment safety, and cost
• Have 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
• Have built or operated CI/CD, environment management, release automation, observability, alerting, and incident response systems
• Have strong backend engineering judgment and can reason about service architecture, APIs, databases, async systems, queues, scaling limits, and production failure modes
• Can write clean, maintainable code and apply strong software engineering judgment across product architecture, infrastructure, backend systems, and developer workflows

Strong candidates may also have:

• Experience operating infrastructure for data-heavy, ML/AI, workflow, marketplace, developer-tools, or enterprise platforms
• Experience designing systems for bursty workloads, long-running jobs, sandboxed execution, distributed workers, or high-concurrency services
• Experience reducing cloud spend through better architecture, autoscaling, workload placement, caching, cleanup systems, or observability
• Experience building internal platforms or tools that make engineers faster without hiding too much complexity

We prioritize technical aptitude, ownership, and learning potential over years of experience.

Team & company details

• Team Size : ~25 people currently, mostly full-time in-person, but some remote.
• Our team includes 4 International Olympiad medalists (IOI, ILO, IPhO), serial AI startup founders, and researchers with publications at ICLR, NeurIPS, etc.
• Company stage: We have 8 figures in both funding and revenue. We’re scaling profitably and quickly to meet very strong demand.

Logistics

• Employment : Full-time.
• Location : 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.
• Visa Sponsorship : We provide support for relocation and visas for strong full-time candidates to the US or Singapore.
• Timeline : Applications are rolling. The process is 2 technical interviews and a 2-3 day work trial.

What we offer

• Competitive compensation
• 100% covered top-of-the-line medical, dental, and vision from Blue Shield of CA (US employees)
• Lunch and dinner when you’re in the office (in-office employees)
• Company-wide holiday break (Christmas Eve to New Year’s Day) on top of PTO and paid holidays
• Other perks including an Equinox membership, 401k, and commuter benefits (US employees)
• Unlimited* 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.
