Collaborate closely with engineers to build systems that survive traffic, edge cases, and timezone madness. Keep an eye on production— Grafana, Kibana & co. are your daily tools. Lead planning, grooming, and shipping with clarity and consistency. Own the backend and API roadmap—laying the foundation for next-gen e-mobility services. Your Profile You’ve led tech products in complex, API-heavy environments. You speak protocols —especially OCPI/OICP —and know how to make them work in production. APIs are your thing—clean design, versioning, and great DX. Logs and metrics guide your thinking—you follow signals, not opinions. You think in edge cases—race conditions, retries, timeouts. You work side by side with engineers and architects, not above them. You've handled migrations, multi-version APIs, and cross-partner integrations.
