  • Experience building reusable component libraries and working with UI frameworks like MUI

  • Familiarity with AWS services (Cognito, S3, EventBridge, Lambda) and IaC tools (Terraform)
  • Understanding of authentication flows (OAuth2, JWT, OpenID Connect)
  • Experience with testing frameworks (Vitest, Playwright, Postman, K6, or equivalents)
  • Strong debugging, problem-solving skills, and high attention to detail
  • Upper-Intermediate English or higher

Nice to Have

  • Experience with financial, ERP, or accounting systems, or data-heavy applications
  • Exposure to AI/ML or analytics-driven applications, or AI-integrated UI features (chat-based interfaces, AI search, embeddings)
  • Understanding of real-time UI updates, event-driven systems, and micro-frontend architecture
  • Experience working with BPMN, Camunda, or workflow engines
  • Understanding of clean architecture, DDD, design systems, and Figma collaboration workflows
