  • Troubleshoot and resolve production issues quickly to ensure reliability

Requirements

  • 5+ years professional backend experience with Python
  • Strong track record building secure, high-performance APIs

  • Solid understanding of event-driven/distributed systems and inter-service communication
  • Proficiency with SQL and NoSQL databases and data modeling
  • Experience with cloud-native deployments and containerization
  • Knowledge of authentication, authorization, and security best practices
  • Familiarity with observability tools and CI/CD pipelines
  • Strong testing discipline and ability to deliver reliable, maintainable systems

Nice to Have

  • Background with Kafka or other streaming/messaging platforms
  • Familiarity with data privacy, compliance, and security standards
  • Experience in early-stage startup environments

Benefits

  • Opportunity to be an early team member with direct product impact
  • Competitive salary + potential equity participation
  • Innovative and supportive team culture
  • Significant growth opportunities as we scale
  • Chance to work hands-on with cutting-edge AI technologies and shape the future of communication
