Job Description
About The Role
We're a fast-moving AI/ML platform startup building infrastructure for reinforcement learning environments, post-training data pipelines, and large-scale agent evaluation. Our engineering team of ~15 includes exceptional technical talent — competition medalists, serial AI startup founders, and published researchers.
As a Platform Engineer, you'll own the reliability, scale, performance, and developer experience of our core infrastructure and systems. This is a backend-architecture-heavy role with real production ownership — your work directly shapes how fast, reliable, and cost-effective our platform is to build on and run.
What You'll Do
- Own production uptime, latency, provisioning speed, infrastructure cost, and incident response for core platform services.
- Build and maintain AWS infrastructure using 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 pipelines, release automation, environment management, and deployment workflows that improve developer productivity and reduce production risk.
- Write clean, maintainable code to automate systems, improve backend services, and create internal tooling.

- Proven track record building or operating CI/CD, release automation, observability, alerting, and incident response systems.
- Strong backend engineering judgment — ability to reason about service architecture, APIs, databases, async systems, queues, scaling limits, and production failure modes.
- Ability to write clean, maintainable code and apply software engineering judgment across infrastructure, backend systems, and developer workflows.
- High ownership mindset; comfortable being accountable for production systems end-to-end.
