Senior Full-Stack Developer Full Time

At Lightrun, we’re closing the gap between AI-generated code and real-world runtime behavior. Our platform restores the critical verification loop in enterprise environments by enabling safe, real-time observability – logs, metrics, and traces injected on demand into live systems – so engineers and AI agents can validate assumptions where code actually runs.Backed by Accel and Insight Partners, and trusted by leaders like Microsoft, Salesforce, Citi, and SAP, Lightrun is building the runtime foundation for the next era of agentic software development.

Join us to build cutting-edge systems, collaborate with world-class engineers, and shape how autonomous software is built in production.
