  • 5+ years of experience in full stack development or backend engineering
  • Advanced Python (async, typing, rigorous testing)
  • Solid DevOps experience: Docker, K8s, GitHub Actions, Terraform
  • Production experience with MongoDB and relational DBs
  • Working knowledge of PHP/Laravel
  • Fluent in English with strong written communication
  • Clear thinking, low ego, high standards, and openness to feedback
  • Fast decision-making with 80% data and high iteration speed

Preferred:

  • Background in ecommerce, retail data or pricing
