About The Position

The Growth team at Close is responsible for the user journey from signup to becoming a paying, retained customer. This includes onboarding, activation, billing, and checkout. The team operates with a focus on rapid learning and iteration, aiming to ship features and improvements in weeks rather than months. Two key projects currently underway are enhancing the agent-forward experience to better demonstrate product value and creating data from unstructured sources, like inboxes, to streamline the CRM setup process. The company is 100% remote, bootstrapped, and profitable, with a strong emphasis on AI integration in both its product and engineering practices. Engineers at Close may move between teams as work evolves.

• Shipped LLM-backed features for real users.
