About The Position

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.

Requirements

• 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.
• Python: 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.

Nice To Haves

• 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.

Responsibilities

• Own the vendor gateway end to end, including protocol clients, abstraction layer, onboarding tooling, and live service contract.
• Work at the intersection of external APIs, real-time systems, and EV-charging domain protocols.
• Develop primarily in Python for backend services and use React for charger onboarding and operations tooling.
