  • Contribute to CI/CD pipelines using GitHub Actions and ArgoCD
  • Collaborate with product, engineering, and deployment teams to deliver reliable production-ready solutions
  • Troubleshoot production issues, improve system performance, and support scalability initiatives
  • Participate in technical discussions, architecture reviews, and engineering best practices

Requirements
  • 7+ years of experience in Full-Stack engineering, working across frontend, backend, and production environments
  • Experience building scalable, high-availability platforms that support large user volumes, complex workflows, and production-critical operations
  • Strong frontend experience with React (Remix), TypeScript, and Vue.js (Vue 2 - legacy)
  • Backend experience using NestJS and building APIs / microservices
  • Solid experience with relational databases (RDBMS) and familiarity with MongoDB and Amazon Redshift
  • Hands-on experience with public cloud platforms (AWS preferred) and services such as S3, SQS, Lambda, Cognito, and API Gateway
  • Experience building event-driven pipelines (S3 1 SQS 1 Lambda), using Python for ETL and data transformation
  • Experience with CI/CD pipelines (GitHub Actions, ArgoCD) and containerized deployments using Docker and Kubernetes (EKS)
