- Own backend services end-to-end, from design to deployment and monitoring.
- Contribute to best practices in code quality, testing, reliability, and observability.
- Help define backend architecture and make strategic technical decisions as the company scales.

- Strong understanding of system design, data structures, and algorithmic principles.
- Comfortable working in high-growth, early-stage environments—a bias toward action and strong product sense are key.
- A collaborative teammate who communicates clearly and is excited to shape the future of a luxury tech brand.
