About The Position

We are looking for a Senior Full Stack Engineer to build and maintain features across the Called platform. This is a full stack engineering role working across React and TypeScript applications, Python and Django services, APIs, and PostgreSQL databases. You should be comfortable building features across the stack, from database models and backend logic to responsive, accessible interfaces. A major part of this role will be taking features from implementation through testing and release. That includes making technical decisions, troubleshooting issues across application layers, and ensuring changes are reliable and maintainable. We’re looking for engineers with hands-on AI experience who build repeatable workflows to accelerate development, improve quality, and reduce repetitive work. This is a senior individual contributor role, not a people-management role or formal technical lead role.
