Software Developer (Java - IoT)

• Key Responsibilities:

• 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

Required skills:

• B.E./B.Tech or ME/M.Tech in Computer Science (or equivalent) from top 150 Nirf engineering colleges.

• 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

• Work with healthcare interoperability standards including FHIR, HL7v2, X12/EDI, CDA, CCD, and REST APIs.

• Develop integrations using APIs, webhooks, event-driven architectures, and secure data exchange mechanisms.

• Build and maintain integrations with platforms such as Epic, Oracle Health/Cerner, athenaHealth, ModMed, and other healthcare applications.
