  • Write clean, maintainable, testable code and contribute to code reviews and engineering standards.
  • Troubleshoot application, deployment, and production issues across the technology stack.
  • Collaborate closely with Data Science, Platform/DevOps, Product, and QA teams to deliver end-to-end product capabilities.

  • Experience building and maintaining CI/CD pipelines using tools such as GitLab CI, GitHub Actions, Jenkins, or similar.
  • Good understanding of Git, branching strategies, pull requests, and code reviews.
  • Experience working with AWS/GCP/AZURE cloud platform.
  • Exposure to Redis, Celery, RabbitMQ/Kafka or similar distributed systems technologies.
  • Good understanding of software engineering principles, testing, debugging, and production support.

What We Look For

not just writing application code.
