About the Role

We are looking for a Senior Full-Stack Developer with a strong focus on backend development to join one of our product teams. This role is ideal for someone who primarily works on backend services and APIs, but is also comfortable contributing to frontend features when needed. You will design and evolve backend logic, data models, and integrations, while collaborating on UI and user-experience aspects of the product. You will work across the stack with end-to-end ownership of features, from backend architecture and implementation to frontend integration and production support.

About the Team

You will join a cross-functional team of around 7 people, including developers, a QA specialist, a Product Manager, a Designer, and a Data Scientist.

The team owns components related to ads and CRM integrations, helping marketing teams run and optimize complex B2B campaigns. We value a product mindset, ownership, and pragmatic engineering over over-engineering.
