Job description

We are looking for a visionary Senior Java Developer to spearhead the development of high-throughput, cloud-native backend systems. In this role, you will go beyond simple coding to architect resilient microservices, design event-driven data pipelines using Kafka, and implement advanced caching strategies to ensure sub-second latency for millions of users. You will serve as a technical leader, bridging the gap between business requirements and scalable technical execution.

KEY RESPONSIBILITIES

• 1. System Architecture & Development
  • Microservices Mastery: Design and implement loosely coupled, scalable microservices using Java 17/21 and Spring Boot 3.x.
  • Event-Driven Design: Architect real-time data streaming solutions using Apache Kafka, focusing on producers, consumers, and KStream applications for eventual consistency.
  • API Excellence: Develop secure, high-performance RESTful and GraphQL APIs with advanced documentation (Swagger/OpenAPI) and security (OAuth2/JWT).
• 2. Cloud & Infrastructure Strategy
  • Cloud-Native Migration: Lead the transition of legacy monolithic systems to cloud providers like AWS, Azure, or GCP using serverless (Lambda/Functions) and containerized services.
  • Orchestration & Scale: Manage containerized environments using Docker and Kubernetes (EKS/GKE) to ensure high availability and auto-scaling.
• 3. Data Persistence & Performance Tuning
  • Polyglot Persistence: Manage complex data models across relational (PostgreSQL, Oracle) and NoSQL (MongoDB, Cassandra) databases.
  • Distributed Caching: Implement multi-level caching strategies using Redis or Memcached to optimize hot-path data retrieval and reduce database load.
  • Query Optimization: Fine-tune complex SQL, JPA/Hibernate mappings, and database indexes for peak performance.
• 4. Leadership & Engineering Excellence
  • Mentorship: Lead code reviews and technical grooming sessions to foster a culture of quality and professional growth within the engineering team.
  • DevOps Integration: Drive CI/CD maturity by automating build, test, and deployment pipelines using Jenkins, GitHub Actions, or GitLab CI.
• 5. Detailed Technical Stack & Requirements
  • Strong experience with Java (11 / 17 / 21) including advanced concepts such as multithreading, concurrency, streams, and virtual threads
  • Hands-on experience with Spring ecosystem including Spring Boot, Spring Security, Spring Data, Spring Cloud, and WebFlux
  • Experience working with messaging systems such as Apache Kafka, RabbitMQ, or AWS SQS / SNS
  • Good exposure to cloud platforms such as AWS (EC2, S3, RDS, Lambda), Microsoft Azure, or Google Cloud Platform
  • Experience with caching technologies like Redis, Ehcache, or Hazelcast
  • Familiarity with DevOps and build tools including Docker, Kubernetes, Terraform, Maven / Gradle, and Git
  • Strong knowledge of databases, both relational and NoSQL, such as PostgreSQL, MySQL, Oracle, MongoDB, or Cassandra
  • Experience with observability and monitoring tools such as ELK Stack (Elasticsearch, Logstash, Kibana), Prometheus, and Grafana
  • Experience with testing frameworks including JUnit 5, Mockito, Testcontainers, and Cucumber (BDD)

REQUIRED QUALIFICATIONS

• education: Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field
• Core Experience: 7–10+ years of professional backend development with a heavy focus on the Java ecosystem
• Distributed Systems: Proven experience building systems that handle high traffic, focusing on fault tolerance and concurrency
• Security Mindset: Deep understanding of OWASP Top 10, data encryption, and secure authentication flows
• Agile Proficiency: Extensive experience working in Scrum/Kanban environments, including sprint planning and effort estimation

Preferred Skills (Bonus)

• Experience with Reactive Programming (Project Reactor) or Java 21 Virtual Threads
• Contributions to open-source projects or active participation in the Java developer community
• Certifications such as AWS Certified Solutions Architect or Oracle Certified Professional (OCP)

Soft Skills

• Strategic Thinking: Ability to evaluate technical trade-offs (e.g., Latency vs. Consistency)
• Effective Communication: Capable of explaining complex technical concepts to non-technical stakeholders and leadership
• Problem-Solving: Disciplined approach to troubleshooting production incidents and root cause analysis.
