Responsibilities

• Design and develop robust Java microservices that are scalable maintainable and aligned with enterprise engineering standards to support critical business applications and customer facing platforms.
• Architect and implement event driven solutions using Kafka to enable reliable asynchronous communication between distributed services and to support real time data streaming across complex ecosystems.
• Optimize AWS based application deployments by selecting appropriate services configuring infrastructure as code and tuning performance to achieve cost efficient secure and highly available environments.
• Collaborate with product owners architects and cross functional engineering teams in a hybrid work model to translate business requirements into detailed technical designs and implementation plans.
• Implement secure coding practices API governance and data protection mechanisms within microservices to ensure compliance with organizational security guidelines and industry regulations.
• Troubleshoot complex production incidents by performing root cause analysis across Kafka streams microservices and AWS components and implement preventive improvements to enhance system resilience.
• Drive continuous integration and continuous delivery pipelines by configuring build test and deployment workflows that accelerate release cycles while maintaining high code quality standards.
• Mentor junior engineers in best practices for Java microservices Kafka event streaming and cloud native design patterns to elevate overall team capability and technical maturity.
• Analyze system performance metrics and application logs to identify bottlenecks and apply targeted optimizations that improve response times throughput and resource utilization.
• Coordinate with site reliability and operations teams to define observability strategies including logging metrics and alerts for Kafka topics and microservices to support proactive monitoring.
• Contribute to technical roadmaps by evaluating emerging tools frameworks and AWS services that can strengthen platform reliability and deliver better experiences for customers and business stakeholders.
• Document architecture decisions service contracts data flows and operational runbooks in clear and accessible formats to support knowledge sharing and sustainable long term maintenance.
• Engage in code reviews backlog refinement and technical discussions during day shifts to ensure solutions are feasible maintainable and aligned with organizational goals without requiring travel.

Qualifications

• Demonstrate strong proficiency in Java and object oriented design with the ability to build clean modular and testable microservices that integrate reliably within distributed systems.
• Apply expert level understanding of Kafka including topic design consumer group strategy and message serialization to implement high throughput and fault tolerant event streaming solutions.
• Utilize hands on experience with AWS services such as compute storage networking and managed data solutions to design secure scalable and cost conscious cloud architectures.
• Bring solid knowledge of microservices principles including service decomposition resilience patterns and interservice communication to ensure loosely coupled and evolvable solutions.
• Exhibit practical experience with hybrid work collaboration tools and agile methodologies to coordinate effectively with onsite and remote team members across projects.
• Employ strong analytical problem solving and debugging skills to diagnose complex issues spanning code infrastructure and data flows and to deliver timely sustainable resolutions.
