[Remote] Senior Software Engineer - Frontend/React (USA Only - 100% Remote)

Note: The job is a remote job and is open to candidates in USA. Close is a CRM company that has been operating since 2013, focused on enhancing sales through communication-first software. The Senior Software Engineer will be responsible for building and improving the frontend of their application using React, collaborating closely with product teams to ensure a seamless user experience.

Responsibilities

• Build the UI that puts AI in the hands of Close customers
• Own the UI for one of the most real-time, high-stakes surfaces in Close: calls
• Build the core surfaces that salespeople and agents both depend on: lead pages, pipeline views, smart search, activity feeds
• Own the surfaces that turn someone who just signed up into a paying customer who sticks around

Skills

• A seasoned frontend engineer
• React is our bread and butter, but perhaps you've worked across Vue, Svelte, or Solid
• You've seen a variety of problems, can collaborate and self-direct
• Building AI-powered interfaces
• You've shipped LLM-backed features for real users and have a POV on where they're trustworthy, where they fall over, and how to make them feel reliable when customers bet their workflow on the output
• You know how to design for streamed responses, uncertain states, and agent-driven UIs
• Working with AI daily
• You use AI tools in your own workflow to ship faster, write tighter code, and reason about unfamiliar parts of the codebase
• We fund the use of AI tools (Claude Code, Codex, and other best-in-class developer tools) and treat learning and experimentation as part of the work
• A builder first
• You'd rather get the first iteration of a feature in front of fifty customers than spend three weeks fretting over a perfect PR
• You ship
• Opinionated about UI craft and component design
• You've built reusable systems that other engineers loved using, and you think about who's on the other end — sales reps in the middle of a call, power users who live in the keyboard, and customers who just need it to work
• Battle-tested
• You've debugged performance regressions in production, owned a component library everyone else relied on, or shipped a high-stakes release where the UX had to be right under real customer pressure

Benefits

• Competitive pay plus an organization-wide goal-based bonus
• ~5 weeks of PTO to start. Plus a 1-week all-company Winter Holiday Break and paid US holidays. You'll earn 2 extra days for every year you're with Close.
• 80% Work Option: Work with your manager to choose between a standard 5-day week or a 4-day week at 80% pay
• Paid leave for primary and secondary caregivers
• A 1-month paid sabbatical every 5 years with the team
• Healthcare (US residents): Two medical plans with Close covering 99% of your premium, plus Dental, Vision, HSA, FSA, and company-paid Long-Term Disability
• 401k (US residents): We match your contributions up to 6%, vested immediately
