Role
Who you are
- 5+ years of experience in an infrastructure, DevOps, or SRE role
- Strong experience with AWS (especially ECS Fargate), Terraform, and Docker
- Experience with GitHub Actions or similar CI/CD tools
- Willingness to learn GCP and Azure for future customer deployments
- Comfortable working directly with engineers, product teams, and (occasionally) customer IT teams
- Highly responsive, organized, and communicative — Slack and synchronous work are a big part of how we collaborate
What the job involves
- Arena is building the operating system for real-time decision-making
- We're a fast-growing startup based in NYC, backed by top-tier investors, and powering mission-critical operations for leading companies across logistics, manufacturing, and supply chain
- We’re hiring our second Infrastructure Engineer — someone who thrives in a fast-paced, high-ownership environment and wants to help build and scale the infrastructure behind a cutting-edge AI platform
- You'll work directly with our Head of Infrastructure to improve our developer experience, strengthen our internal tooling, and support deployments into customer cloud environments
- Own and improve CI/CD pipelines (primarily GitHub Actions) for internal and customer-facing services
- Write and maintain Terraform infrastructure across multiple AWS environments (ECS Fargate, networking, IAM, etc.)
- Support customer deployments — including working directly with their IT teams to deploy Arena into their cloud (AWS, GCP, Azure)
- Enhance developer workflows to make building, testing, and deploying easier and faster
- Monitor infrastructure performance and cost, and drive cost-optimization initiatives
- Review infrastructure PRs, collaborate closely with your team lead, and help define our best practices
- Be part of a small, fast-moving team where you’ll have meaningful ownership from day one
Our take
Arena leverages performance data, predictive algorithms, and machine learning technology to help businesses automate high frequency decisions. In theory, the platform can be used to automate marketing strategies, promotions, inventory and supply chain management, pricing, and more.
Although AI automated decision-making may sound overly ambitious at first, a closer look suggests that it’s actually a natural progression from the huge growth of AI-powered data analytics companies. Arena separates itself from these by providing the next actionable step, rather than leaving these decisions up to internal teams.
Since launching in 2020, the company has moved from early promise into a more established growth phase. Its technology is now used by major global businesses, including Anheuser-Busch InBev, showing that automated decision-making is becoming a practical reality. Rather than being defines by a single fundraiser, Arena's progress today is about continued execution, expanding use cases, improving its models, and embedding deeper into enterprise workflows as demand for real-time, automated decisions continues to grow.
