About This Role

We are hiring a Senior Software Engineer to own the infrastructure behind our product and engineering team. You will build and run the systems that power real-time dispatch decisions for customers, the sandboxes and evaluation harnesses engineers use to ship agent workflows, and the developer platform the team builds on. You will work directly with product engineers and the customers affected by this infrastructure. This role is on-site at our Manhattan office.

What You’ll Own

• Product infrastructure: Build and operate the infrastructure behind our real-time decision systems, including durable execution, workflow orchestration, reliability, and performance for products customers rely on to run their businesses.
• Agent infrastructure: Build the sandboxes, evaluation infrastructure, and harnesses engineers use to develop and ship agent workflows, including the compute environments in which agents execute.
• Developer platform: Own CI/CD, deployment, local development, and internal tooling—the abstractions that help the team ship in days rather than quarters.
• Reliability and observability: Build instrumentation, monitoring, incident response, and debugging tools for systems whose failure modes can be probabilistic rather than deterministic.
• Cost and scale: Manage cloud and inference costs as the product grows, and make capacity and architecture decisions before they become bottlenecks.
• Engineering partnership: Work directly with product engineers building on your infrastructure and with the customers affected by it.

Requirements

• 3–6 years of engineering experience with meaningful infrastructure ownership
• Strong fundamentals in distributed systems, cloud infrastructure, networking, CI/CD, and observability
• Ability to write code and own complex systems end to end, from design through production
• Experience building and owning infrastructure from scratch across cloud platforms (AWS/GCP), Kubernetes, Terraform, CI/CD, and observability
• Go or Python experience; experience with agent sandboxes or LLM cost and observability tooling is a plus

Responsibilities

• Build and operate infrastructure for real-time decision systems
• Implement instrumentation, monitoring, incident response, and debugging tools
• Manage cloud and inference costs as the product scales
• Partner with product engineers and customers on infrastructure needs
