Senior Java Developer

Experience Level: Senior (5–10 Years)

About the Role

We are looking for a Hands-On Senior Software Engineer to build and scale high-throughput, cloud-native microservices and event-driven systems.

Important Note for Applicants:

This is not a traditional, maintenance-only Java role. We require proven, production-level expertise in Apache Kafka, AWS Cloud, Spring Boot, and Node.js. Candidates with only high-level conceptual knowledge or keyword-stuffed resumes will not pass our technical evaluation. You will be expected to demonstrate deep hands-on proficiency during live system design and coding assessments.

Mandatory Technical Qualifications (Non-Negotiable)

To be shortlisted, you must meet the following core requirements:

• Java & Spring Boot Ecosystem (5+ Years): Expert-level fluency in Java 8+, Spring Boot, Spring Cloud, Hibernate/JPA, and microservices design principles.
• Production Apache Kafka Expertise (Proven Experience): Hands-on experience configuring Kafka brokers, writing custom producers/consumers, optimizing topic partitioning, managing consumer groups, handling schema registries, and working with serialization standards (Avro, JSON).
• AWS Cloud & Serverless Architecture (Proven Experience): Production experience architecting on AWS (Lambda, ECS/EKS, S3, DynamoDB, API Gateway, CloudWatch).
• Node.js & Integration (Hands-on Proficiency): Practical experience developing asynchronous microservices and APIs using Node.js alongside Java.
• Modern API & Front-End Exposure: Deep experience building RESTful APIs, with working knowledge of modern UI frameworks (Angular) to collaborate effectively with front-end teams.
• DevOps & Containerization: Hands-on proficiency with Docker, Kubernetes, CI/CD pipelines (Jenkins/GitHub Actions), and Infrastructure as Code.

What You Will Do

• Architecture & System Design: Architect and build event-driven pipelines and low-latency microservices that scale seamlessly under heavy workloads.
• Production-Grade Implementation: Write clean, modular, and fault-tolerant code using Java, Spring Boot, Node.js, and Kafka.
• Performance Optimization & Reliability: Own system reliability, diagnose performance bottlenecks, analyze log streams, and optimize database/Kafka query efficiency.
• Technical Governance: Lead technical discussions, conduct rigorous code reviews, enforce strict engineering best practices, and mentor junior developers.

Candidate Checklist — Do You Qualify?

Before applying, ask yourself:

• Have you built and deployed event-driven architectures using Apache Kafka in a production environment?
• Can you comfortably write backend services in both Spring Boot and Node.js?
• Do you have hands-on experience designing cloud services on AWS beyond basic EC2 instances?

If you answered YES to all three and are ready to tackle complex system design challenges, we want to hear from you.
