• Contribute to frontend development when needed (React and React Native)
• Evolve our IoT ingestion pipelines using AWS IoT Core, MQTT, Redis, BullMQ
• Build new features on top of our modern architecture and support the gradual modernization of existing components
• Work with databases including PostgreSQL, and occasionally MySQL and MongoDB, designing scalable schemas and efficient queries
• Collaborate closely with Product and Engineering to deliver reliable, secure, and maintainable solutions
• Participate in code reviews, architectural discussions, and technical decision-making
• Contribute to our growing AI Agent ecosystem by integrating backend services with LLM-based workflows and internal MCP tooling
• Help improve our DevOps, CI/CD, and observability capabilities
