• Solid experience with SQL and relational databases (e.g. MySQL/MariaDB, PostgreSQL).
• Experience writing automated tests (unit, integration, and end‑to‑end where appropriate).
• Experience collaborating in multidisciplinary teams (product, design, data, ops).
• Comfort operating in a high‑ownership environment with changing priorities and quick iteration.

• Technical decisions balance simplicity, reliability, and maintainability, resulting in systems that are easy to operate and evolve.
• The quality of the codebase and production systems improves through your contributions (structure, testing, observability).
• The team benefits from reusable patterns and shared solutions that reduce duplication and cognitive load.
• 🎓Access to professional development tools and resources (courses, books, workshops, etc.)
• 💊Unlimited virtual medical assistance (general practitioner, nutritionist, psychologist) for you and 3 family members
• 🏈 Access to physical wellness tools (TotalPass)
