Optimize performance, reliability, and cost efficiency in AWS environments
Participate in CI/CD pipelines and automated deployments
Collaborate with product, QA, and cross-functional teams to ship high-quality releases
What We’re Looking For
4-8+ years of software engineering experience
Strong hands-on experience with AWS Serverless (Lambda, S3, API Gateway)
Proficiency in Nodejs for backend development
Solid understanding of cloud-native architecture and distributed systems
Experience working in Agile environments with CI/CD pipelines
Experience building modern front-end applications with React / ReactJS (Nice to have)
