About The Position

Arena Intelligence is seeking a Cloud Infrastructure Engineer to drive the strategy and execution of the platform that runs Arena. The role owns the infrastructure enabling Arena's applications, API, AI agents, compute, and data pipelines, including how these systems are hosted, connected, and secured across multiple clouds and managed platforms. The engineer will make decisions about application hosting, execution of long-running agent workflows, and when to use managed services versus operating systems directly, then implement those decisions with the team.

The role partners closely with product, research, data, and security teams to make the platform reliable at scale, fast to build on, and secure by default. It sets standards for identity, secrets, networking, and infrastructure as code, and helps grow the infrastructure team. The position also includes owning cloud architecture, establishing reliability practices, and continuously improving infrastructure cost and risk.

Requirements

• At least 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, including OIDC and workload identity federation, IAM design, secret managers, and key rotation.
• Experience running serverless or edge platforms, such as Vercel, Cloud Run, Lambda, or Cloudflare Workers, and judgment about 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.

Nice To Haves

• Experience building infrastructure for AI products, such as sandboxed code execution, model serving, or GPU clusters.
• Experience with data platforms such as Databricks 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.

Responsibilities

• Own Arena's cloud architecture end to end, including hosting, compute, networking, and infrastructure supporting products.
• Decide and execute the hosting and workload strategy across serverless and edge platforms, containers and Kubernetes, and durable execution for long-running AI agent workflows.
• Build identity and access systems using workload identity, least-privilege IAM, short-lived credentials, and centralized, audited secrets management.
• Design network boundaries, private connectivity, and egress controls for databases and services.
• Manage infrastructure as code with clear ownership, CI/CD, and review practices.
• Establish reliability practices, including SLOs, monitoring and alerting, on-call, incident response, and post-incident follow-through.
• Make infrastructure cost and risk visible and improve them continuously.
• Help hire and mentor the infrastructure team as it grows.

Benefits

• Competitive compensation aligned to the markets where team members are based; compensation ranges are listed on role postings and depend on experience and work location.
• Comprehensive health and wellness benefits, including medical, dental, vision, and additional support programs.
• Opportunity to work on cutting-edge AI with a small, mission-driven team.
• A culture that values transparency, trust, and community impact.
