We are seeking a Specialist – Java/Spring Boot Lead with strong hands-on coding experience to lead the design and development of event-driven transactional microservices on AWS.

This is a hands-on Lead role, not an Architect position. The ideal candidate will establish development frameworks, create project scaffolding, and provide a strong technical foundation for development teams.

• Design and implement AWS-based solutions using ECS, Aurora PostgreSQL, SQS FIFO, Event Bridge, and MSK.
• Develop high-volume transactional systems with concurrency controls.
• Collaborate with developers to establish coding standards and best practices.
• Support CI/CD pipelines and infrastructure automation.
• Troubleshoot performance, reliability, and production issues.

Required Skills

• 7+ years of hands-on Java/Spring Boot development experience.
• Strong experience with Java 17 and Spring Boot.
• Hands-on AWS experience with ECS, Aurora, SQS, and EventBridge.
• Strong experience building transactional systems and microservices.
• Experience with Kafka/MSK.
• Experience with concurrency controls such as advisory locks and optimistic versioning.
• Experience with GitLab CI/CD.
• Hands-on experience with Terraform or AWS CDK.
• Strong technical leadership and hands-on coding skills.

Preferred Skills

• State machine design patterns.
