Java Full Stack Developer Lead
10-12 years exp
Role is onsite 5 days/wk
We are seeking a Full-Stack Senior Java Engineer to architect, design, and build scalable, secure, high-performance applications across both the back end and front-end using Java, Spring Boot, and React. You'll work in a cross-functional team to deliver resilient microservices, build responsive user interfaces, optimize Oracle database performance, and strengthen engineering excellence through code reviews, mentorship, and automation.
Key Responsibilities
o Architect, design, and develop scalable, secure, high-performance full-stack applications using Java, Spring Boot, and React.
o Build and maintain responsive, intuitive front-end interfaces using React, modern o JavaScript/TypeScript, HTML, and CSS.
o Build and maintain microservices-based systems with a strong focus on reliability, resilience, and observability.
o Design, build, and operate event-driven microservices, including service decomposition, inter-service communication, API contracts, and fault-tolerance patterns (circuit breakers, retries, idempotency).
o Develop and manage asynchronous, event-streaming pipelines using Kafka, including topic design, partitioning, consumer groups, and exactly-once/at-least-once delivery semantics.
o Deploy, scale, and manage containerized applications on Kubernetes, including deployments, auto-scaling, and service discovery.
o Build and run cloud-native workloads on AWS, leveraging services such as EKS, EC2, S3, RDS, Lambda, and CloudWatch.
o Design and optimize Oracle database schemas, SQL queries, and PL/SQL stored procedures; perform performance tuning.
o Collaborate with Product, QA, DevOps, and UX partners to deliver end-to-end solutions.
o Participate in code reviews, mentor junior developers, and promote engineering best practices and coding standards.
o Troubleshoot production issues, perform root-cause analysis, and drive continuous improvements to system performance and stability. Contribute to CI/CD pipelines and automation to streamline development, testing, and deployment.
