• Hands-on experience with AWS cloud services (EC2, S3, Lambda, Kinesis, Firehose, DynamoDB, EKS, CloudWatch, and related tools)
• Experience with relational and NoSQL databases (DynamoDB, PostgreSQL); familiarity with DB2 is a plus
• Proficiency using modern monitoring and observability platforms (Splunk, Honeycomb) and automated testing frameworks (API testing tools, Playwright)

• Modernize legacy systems by evaluating current-state architectures and defining target-state solutions that maximize performance, scalability, and maintainability
• Deliver high-quality software in an agile environment, partnering closely with product managers, architects, and other engineering teams
• Own the end-to-end development lifecycle: requirements gathering, solution design, coding, testing (including API and Playwright automation), deployment, and operational support
• Implement and manage AWS cloud services (e.g., EC2, S3, Lambda, Kinesis, Firehose, DynamoDB, EKS, CloudWatch) to build resilient, observable, and secure solutions
• Promote best practices in coding standards, testing, monitoring (via Splunk, Honeycomb), and documentation
• Mentor and guide engineers, fostering a culture of technical excellence, ownership, and continuous improvement
• Engage directly with clients and stakeholders, translating broad, ambiguous business needs into concrete technical plans
