Senior Frontend Engineer – Growth (USA Only – 100% Remote)

Key Highlights

• Agent-forward experience. We’re exploring how agents and AI can make the experience better for our customers and demonstrate the value of Close faster. Our focus is helping users get real value from the product, not just automating on their behalf.
• Creating data from unstructured sources. We’re building ways to turn the information customers already have, like their inbox, into a working CRM, so they can skip the manual data entry and see value from Close faster.
• A seasoned frontend engineer. React is our bread and butter, but perhaps you’ve worked across Vue, Svelte, or Solid. You pick the right tool for the problem rather than retreating to what you know. You’ve seen a variety of problems, can collaborate and self-direct.
• Fluent in experimentation. You understand what data points to capture in an experiment, what a funnel looks like, and how to design a feature so it produces meaningful data — not just ship it and hope. This is the core of the role.
• Experienced with B2B experiment structure. A strong bonus: you’ve worked in Amplitude on the implementation side, not just the technical configuration side.
