Company Overview:

Our client is a fast-growing mobility technology enterprise building cloud-native infrastructure for the electric vehicle (EV) sector. Operating distributed, real-time, and event-driven architectures, they are seeking an experienced Senior Backend Engineer to support the expansion, optimization, and operational stability of their core EV Charging platform. In this contract role, you will work independently on backend services, optimize database operations, troubleshoot live production issues, and collaborate closely with technical leads and DevOps teams.

Key Responsibilities:

• Backend & API Development: Design, build, and maintain scalable microservices and RESTful APIs using Golang.

• Cloud & Containerization: Practical experience with cloud-native deployments (AWS or Azure), Docker, and Kubernetes orchestration.
• High-Traffic Debugging: Proven capability in isolating, debugging, and resolving performance bottlenecks and outages in distributed/high-traffic systems.
• Independent Execution: Ability to take ownership of technical features and deliver reliable code independently within a distributed environment.

Nice-to-Have:

• Prior exposure to EV charging networks, mobility solutions, IoT platforms, or hardware-integrated architectures.
• Familiarity with domain protocols such as OCPP and OCPI.
• Hands-on experience with observability tools (Datadog, Sentry) and Infrastructure-as-Code (Terraform).
• Beginner-to-intermediate knowledge of Java.
