Senior Full-Stack Developer

This is a hands-on, high-ownership engineering role: you will architect systems, write production-grade code, design efficient data flows, and ship end-to-end features that directly shape our product experience.

• Design, architect, and implement backend services, microservices, and internal tooling
• Build modern, responsive, and performant frontend applications using React, TypeScript, and Tailwind
• Develop and maintain RESTful and GraphQL APIs that power key platform functionalities
• Integrate third-party services, authentication systems, and enterprise connectors
• Collaborate with product and design to craft intuitive user experiences and smooth interaction flows
• Deploy and manage containerized applications using Docker and Kubernetes
• Work with databases such as Postgres, Redis, and/or ClickHouse—handling schema design, migrations, and query performance
• Implement and maintain CI/CD pipelines, testing frameworks, and release workflows
• Troubleshoot production issues, performance problems, and service reliability incidents
• Take full ownership of features from design to production, including documentation and monitoring
