ABOUT THE ROLE

We are looking for a Senior Java Full Stack Developer to design, build, and scale mission-critical platforms for a high-growth enterprise environment. You will take end-to-end ownership of cloud-native microservices on AWS, architect event-driven pipelines with Apache Kafka, and deliver robust Spring Boot APIs consumed by modern React front ends. This is a hands-on engineering role with meaningful influence on architecture, standards, and team capability.

REQUIRED QUALIFICATIONS:

- 10+ years of professional software engineering experience, with at least 3 years architecting cloud-native services on AWS.

- Expert-level proficiency in Java 11+/17, Spring Boot, Spring Cloud, and Spring Security; strong understanding of JVM internals and performance tuning.

- Hands-on production experience with Apache Kafka: topic design, consumer group management, schema registry, and stream processing (Kafka Streams or equivalent).

- Solid understanding of microservices patterns: service decomposition, API gateway, circuit breaking, event sourcing, and CQRS.

- Strong AWS skills across compute (ECS/EKS/Lambda), networking (VPC, ALB, API Gateway), storage (RDS, DynamoDB, S3), messaging (SNS/SQS, EventBridge), and security (IAM, KMS, WAF).

- Proficient with CI/CD tooling (GitHub Actions or Jenkins), containerisation (Docker), and IaC (Terraform or CloudFormation).

- Experience with SQL (PostgreSQL/Aurora/MySQL) and NoSQL (DynamoDB/DocumentDB); practical Redis caching strategies.

- Front-end capability in React + TypeScript, including component architecture, routing, and state management.

- Strong written and verbal communication; ability to influence technical direction and mentor engineers.
