Infrastructure Engineer

Job Overview

HappyRobot is the AI-native operating system for the real economy—a system that closes the circuit between intelligence and action. By combining real-time truth, specialized AI workers, and an orchestrating intelligence, we help enterprises run complex, mission-critical operations with true autonomy. Our AI OS compounds knowledge, optimizes at every level, and evolves over time. We’re starting with supply chain and industrial-scale operations, where resilience, speed, and continuous improvement matter most—freeing humans to focus on strategy, creativity, and other high-value tasks. HappyRobot has raised $62M to date, including our most recent $44M Series B in September 2025. Our investors include Y Combinator (YC), Andreessen Horowitz (a16z), and Base10—partners who believe in our mission to redefine how enterprises operate.

About the Role

We're looking for an Infrastructure Engineer to take the lead on scaling our operational resilience as we grow. You’ll own the stability, observability, and debugging workflows that keep our systems running smoothly. You'll be the go-to person for untangling complex failures in real time, designing tools that turn chaos into clarity, and helping us shift from reactive to proactive operations. This is a high-impact, high-trust role where you’ll shape how reliability is done - reducing incident load, building internal tooling, and directly improving developer focus and system uptime.

Required Qualifications

• 3+ years of hands-on experience debugging production systems (logs, traces, incidents, etc.)
• Strong problem-solving skills and ability to dive into unfamiliar backend codebases
• Strong Go and Kubernetes experience
• Familiarity with observability and monitoring tools (e.g., Datadog, Prometheus, Sentry)
• Clear, calm communication under pressure — especially during live incidents

Nice-to-Have

• Experience working with distributed systems or services at scale
• Built or maintained internal tooling for on-call teams or reliability workflows
• Familiarity with deployment pipelines, CI/CD, or infra-as-code
• Experience improving system observability (e.g., custom metrics, traces, log pipelines)
