This role will be responsible for leading backend architecture and solution design, ensuring production stability, and mentoring engineers across multiple backend services.

You will collaborate closely with product, engineering, and infrastructure teams to build resilient, high-performance systems that operate at scale in a cloud-native environment.

Key Responsibilities

• Lead backend architecture and system & solution design
• Own end-to-end delivery of backend services
• Ensure highly availability, scalability, performance and security
• Drive engineering best practices, code quality, and design reviews
• Improve database performance, indexing strategies, query efficiency, and overall cost optimization
• Lead production incident investigations and root cause analysis
• Design and implement event-driven and asynchronous systems
• Work closely with DevOps on deployment, monitoring, and reliability
• Balance speed of delivery with long-term scalability and maintainability
• Mentor engineers and drive technical initiatives across teams

What You’ll Need

Technical Requirements (Must Have)

• Strong experience in Golang and building production systems
• Beginner to Intermediate knowledge in Java is a plus
• Deep understanding of concurrency, memory profiling, and performance optimization
• Experience designing RESTful APIs and system to system integrations
• Strong SQL knowledge and experience with PostgreSQL or similar RDBMS
• Experience with event streaming systems (e.g., Kafka) and realtime communication protocol (e.g. WebSockets)
• Hands-on experience debugging production issues

• Integrations with external platforms, protocols, and third-party systems
• High observability and operational ownership expectations
• Rapidly evolving platform with scaling and optimization challenges

Engineering Culture

We value engineers who take ownership beyond feature delivery — including system reliability, scalability, observability, and operational excellence. Technical Leads are expected to contribute hands-on, mentor engineers, participate in architecture discussions, and drive continuous improvements across engineering practices and platform stability.

What We’ll Provide

You will play a key role in shaping the backend architecture of a rapidly scaling, cloud-native platform, working on distributed systems, real-time processing, and high-availability services. This role offers the opportunity to influence core technical decisions, solve complex engineering challenges, mentor a growing engineering team, and gain exposure to device-integrated and event-driven platforms, including technologies and protocols used in EV Charging domain.
