Full Stack Developer

**Full Stack Developer – React \& Node.js** **Location:** Foster City, CA **Work Arrangement:** Onsite – 4 Days per Week, Day 1 Onsite **Employment Type:** Contract Please use the following JD: **Software Engineer — Charging Vendor Integrations** **Team: Charging Infrastructure / Fleet Platform · Level: Mid–Senior** **About the role** Client operates its own charging network and relies on third\-party charging providers (e.g., EVgo) spanning multiple hardware manufacturers and vendor platforms. We're building a single vendor gateway. You'll own that gateway end to end: the protocol clients, the abstraction layer, the onboarding tooling, and the live service contract our fleet systems depend on. This is a backend engineering role at the intersection of messy external APIs, real\-time systems, and EV\-charging domain protocols. **Our stack is Python on the backend and React on the frontend** — you'll live primarily in **Python**, with **React** for the charger onboarding and operations tooling. **What we're looking for** Strong backend engineering experience building and operating production services and API integrations against unreliable or inconsistent external sources. Experience designing canonical data models / abstraction layers over heterogeneous third\-party systems. Comfort with event\-driven or streaming systems feeding real\-time consumers, and the reliability mindset that comes with owning a live service (observability, retries, graceful degradation). Ability to own a service across the stack — stand it up, deploy it, monitor it — without needing hand\-holding on infra. **Skills** **Python** — primary language; production experience building backend services and API clients (async, typing, and a modern framework such as FastAPI/Django/Flask). **React** — for building and maintaining the charger onboarding and operations UI (TypeScript a plus). **API integration** — REST/webhooks, plus comfort querying vendor databases (SQL) where no clean API exists. **Data modeling** — designing canonical schemas and reconciling inconsistent inputs across sources. **Real\-time / event\-driven systems** — message queues or streaming (e.g., Kafka), and the observability tooling to run them. **Cloud \& operations** — deploying and monitoring services in a cloud environment (AWS/GCP), containers, CI/CD. Strong signals (nice to have) Hands\-on experience with OCPP (Open Charge Point Protocol) — charger\-to\-central\-system communication across manufacturers. Hands\-on experience with OCPI (Open Charge Point Interface) — the roaming/interoperator protocol for integrating third\-party networks (locations, tariffs, session data, real\-time status). Prior work in EV charging, energy, telematics, IoT device fleets, or other domains that involve normalizing data from many hardware vendors. DevOps/SRE fluency (IaC, CI/CD, cloud infra, monitoring) as a complement to strong application engineering.
