You’ll have direct access to decision-makers, substantial autonomy, and the ability to influence both the product and the company’s technical direction.We’re looking for someone who wants to own a product—not simply contribute code to one. To apply, please share a short introduction describing the products you’ve helped launch, the systems you personally owned, and any relevant examples of your work.
