  • Strong testing practices
  • Deep understanding of software architecture, design patterns, and microservices
  • Experience with AWS services — Lambda, SQS, S3, and others
  • Experience with containerized environments and Kubernetes
  • Good communication and collaboration skills.
  • Будет плюсом: Experience in fintech, crypto, or payment systems is a plus
Условия
  • Work alongside a team of skilled engineers on a product used by millions
  • Build with a modern, thoughtfully chosen tech stack
  • Minimal bureaucracy and fast decision-making
