  • Build and maintain a RESTful API for the service
  • Maintain CI/CD pipelines (GitLab CI)
  • Implement comprehensive monitoring and logging to track service health, performance, and cost. Proactively identify and resolve bottlenecks or issues
  • Work closely with our cloud engineering, data science, and AI Platform teams to ensure seamless integration, operational excellence, and alignment with company-wide standards
  • Focus on delivering value to business users

Requirements

  • Over 5 years of professional software engineering experience with a focus on Python, including designing and building scalable, production-grade applications
