As our cloud infrastructure engineer, you'll partner closely with product, research, data, and security to make our platform fast to build on, reliable at scale, and secure by default. You'll set the standards for identity, secrets, networking, and infrastructure-as-code, and you'll help grow the infrastructure team as we scale.
YOU'LL
Own Arena's cloud architecture end to end: hosting, compute, networking, and the infra our products are built on.
Decide and execute on our hosting and workload strategy, including serverless and edge platforms, containers and Kubernetes, and durable execution for long-running AI agent workflows.
Build identity and access the right way: workload identity, least-privilege IAM, short-lived credentials, and centralized, audited secrets management.
Design network boundaries, private connectivity, and egress controls for our databases and services.
Manage all infrastructure as code with clear ownership, CI/CD, and review practices.
Establish reliability practices: SLOs, monitoring and alerting, on-call, incident response, and post-incident follow-through.
Keep infrastructure cost and risk visible, and improve them continuously.
Help hire and mentor the infrastructure team as we grow.
YOU'LL HAVE
6+ years of experience building and operating production cloud infrastructure, including owning architecture decisions at a fast-growing company.
Deep hands-on experience with GCP and/or AWS, Kubernetes, and Terraform (or a similar infrastructure-as-code tool).
Strong experience with cloud identity and secrets at scale: OIDC and workload identity federation, IAM design, secret managers, and key rotation.
Experience running serverless or edge platforms (e.g. Vercel, Cloud Run, Lambda, Cloudflare Workers) and the judgment to know when to use them.
Experience with queues, workflow engines, or durable execution systems for long-running and asynchronous workloads.
A track record of leading infrastructure through incidents and turning lessons into lasting improvements.
Clear written communication and the ability to explain trade-offs to engineers and leadership.
BONUS POINTS
Experience building infrastructure for AI products, such as sandboxed code execution, model serving, or GPU clusters.
Experience with data platforms (Databricks or similar) and Postgres at scale.
Background in cloud security, detection engineering, or security posture tooling.
Experience as the first infrastructure hire at a fast-growing startup.
