Staff Engineer, Software (Backend)

What you will do: 

• Design, build, and maintain high-throughput Java + Spring Boot microservices serving millions of devices 

• Develop RESTful APIs (JSON/XML) secured with JWT and OAuth 2.0 

• Work with MongoDB as the primary data store, designing schemas and queries for scale 

• Build and consume event-driven architectures using Kafka, AWS SQS/SNS, and Kinesis 

• Containerize services with Docker and deploy on AWS EKS (Kubernetes) via CI/CD pipelines 

• Collaborate on system design for high availability, disaster recovery, scalability, and performance 

• Write clean, testable, well-documented code with strong unit and integration test coverage 

• Participate in code reviews, architectural discussions, and sprint planning 

• Own features end-to-end — from design and implementation through deployment and production monitoring 

• Troubleshoot production issues, perform root-cause analysis, and drive reliability improvements 

• Leverage AI-powered development tools for code generation, automated code reviews, test creation, technical planning, and debugging — continuously improving team productivity and code quality 

Who you are and what you bring:

• B.E./B.Tech in Computer Science (or equivalent) from a reputed institution 

• 8+ years of hands-on back-end development experience 

• Strong proficiency in Java (8+) and the Spring ecosystem (Spring Boot, Spring Data, Spring Security) 

• Solid experience with NoSQL databases (MongoDB preferred) — schema design, indexing, aggregation pipelines 

• Practical experience with AWS services (EC2, S3, SQS, SNS, Lambda, EKS, CloudWatch, or similar) 

• Familiarity with Docker, Kubernetes, and container orchestration 

• Experience with Git, Bitbucket/GitHub, and CI/CD tooling (Jenkins, GitHub Actions, or similar) 

• Understanding of RESTful API design principles, versioning, and security (OAuth 2.0, JWT) 

• Strong organizational skills — ability to define, track, and deliver work independently 

• Excellent problem-solving, critical thinking, and analytical skills 

• Clear, concise written and verbal communication 

• Experience with event streaming platforms — Kafka, AWS Kinesis 

• Working knowledge of AWS Lambda and serverless architectures 

• Understanding of WebSockets and persistent connection protocols (e.g., OCPP) 

• Knowledge of networking fundamentals — TCP/IP, TLS, load balancing, connection keep-alive, timeout tuning 

• Experience with AWS ALB/NLB, target groups, health checks, and sticky sessions 

• Exposure to Elasticsearch / OpenSearch for search and analytics workloads 

• Familiarity with SQL databases (MySQL/PostgreSQL) as a secondary skill 

• Experience with front-end technologies (React, JavaScript/TypeScript) — full-stack capability is a plus 

• Knowledge of caching layers (Redis, ElastiCache) 

• Understanding of observability — structured logging, distributed tracing, metrics (Datadog, ELK, Prometheus) 

• Familiarity with shell scripting (Bash) for automation, debugging, and operational tasks 

• Exposure to OCPP (Open Charge Point Protocol) or EV/IoT domain 

• Experience using AI coding assistants (GitHub Copilot, Windsurf/Cursor, ChatGPT, Claude) for development, code review, and technical planning 

• Experience working in renewable energy, clean tech, or IoT companies 

• You thrive in a fast-paced environment with ambiguity and evolving priorities 

• You take ownership — proposing solutions, not just implementing tickets 

• You care about code quality — clean architecture, meaningful tests, thoughtful PR reviews 

• You can context-switch across projects without losing momentum 

• You communicate status, risks, and trade-offs proactively to the team
