About The Position

Join the LTK Family! We are searching for a senior software engineer to join the Creator organization. This team is responsible for the user experiences and systems used to onboard creators and drive their growth across LTK, one of the largest creator-guided shopping and brand marketing platforms in the industry.
The ideal Senior Software Engineer for this space will be organized, productive, and comfortable working across the full stack.
