You’ll work closely with customers and help shape the product to solve their problems. We’re looking for people who are not only comfortable with uncertainty, but actively thrive in it. You should want to ship unreasonably fast and iterate rapidly. You should challenge assumptions, solve from first principles, and take great pride in building features that customers love. You’ll work as closely with a team of talented engineers as you will with product and design. You’ll quickly accrue autonomy and responsibility. THE ROLE We’re hiring Software Engineers to build AI agents that power the next generation of LiveFlow. This is a full-stack role at its core, with a strong focus on designing and developing agent-driven systems embedded throughout the product.
