About the Role

We are seeking a highly skilled Senior Java Developer with strong expertise in Spring Boot, event‑driven architectures, and Apache Kafka, as well as hands-on experience developing and deploying services in Azure or Google Cloud Platform (GCP). This role also requires familiarity with Microsoft Copilot, Generative AI technologies, and integrating AI-assisted coding workflows to accelerate development.

You will design and deliver scalable backend services, modernize cloud-native applications, and contribute to innovation initiatives leveraging GenAI.


Key Responsibilities

1. Backend Engineering

  • Design, develop, and optimize Java/Spring Boot microservices with clean architecture and high scalability.
  • Implement RESTful APIs, asynchronous messaging, and event-driven patterns.
  • Apply secure coding practices, API contracts, and comprehensive unit/integration test coverage.

2. Event Streaming & Distributed Systems

  • Build and maintain Kafka pipelines, topics, schemas (Avro/JSON), and consumer/producer applications.
  • Design real-time event streaming, pub/sub architectures, and message replay/retention strategies.
  • Work with schema registries, message partitioning, and high-throughput processing.

3. Cloud Engineering (Azure or GCP)

  • Deploy, manage, and monitor applications using:
    • Azure: App Services, AKS, Functions, ACR, Event Hub, Cosmos DB, Key Vault
    • GCP: Cloud Run, GKE, Pub/Sub, IAM, Cloud Functions, Cloud SQL/Firestore
  • Build CI/CD pipelines using GitHub Actions, Azure DevOps, or Cloud Build.
  • Implement cloud-native patterns: autoscaling, resilience, observability, secret management.

4. Copilot & Generative AI Integration

  • Use GitHub Copilot and other AI-assisted tools to accelerate development and improve code quality.
  • Contribute to building GenAI-enabled features, such as:
    • Intelligent code generation
    • Conversational interfaces
    • ML/LLM-based service integrations
  • Collaborate with data/AI teams to integrate GenAI services via REST APIs or cloud AI platforms.

5. Systems Design & Architecture

  • Work across teams to define architecture for backend services, event pipelines, and cloud deployments.
  • Lead design reviews, conduct POCs, and provide technical mentorship to junior developers.
  • Promote best practices for distributed systems, cloud-native development, and enterprise integration.

Required Qualifications

  • 6+ years of hands‑on Java development experience.
  • Strong expertise in Spring Boot, Spring Cloud, JPA/Hibernate.
  • Experience building microservices and distributed systems.
  • Deep knowledge of Apache Kafka, including consumers, producers, partitions, offsets, schema registry.
  • Hands-on experience with Azure or GCP cloud services.
  • Strong understanding of CI/CD, Git, DevOps concepts.
  • Experience using GitHub Copilot, Azure AI Studio, or similar AI-assisted development tools.
  • Solid knowledge of REST APIs, JSON, secure coding, OAuth2/JWT.
  • Strong problem‑solving, debugging, and performance tuning skills.

Preferred Qualifications

  • Experience with Kubernetes (AKS or GKE) and containerization using Docker.
  • Familiarity with serverless (Azure Functions, Cloud Functions).
  • Experience integrating LLM/GenAI APIs (OpenAI, Azure OpenAI, Vertex AI).
  • Knowledge of event-driven design patterns and CQRS.
  • Exposure to NoSQL databases (Cosmos DB, Firestore, MongoDB).
  • Experience in Agile/Scrum development environments.
  • Understanding of AI governance, prompt engineering, and RAG architecture.
