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

About Us

Since 2013, we've been building a CRM that gets out of your way and helps your team sell more, faster. No manual data entry, no 10-click workflows. Just communication-first sales software designed to help you succeed and scale.

Our Stack

• Frontend: Single-page TypeScript web app built in React, bundled with Vite and targeted at modern browsers.
• Testing: Uses Vitest, React Testing Library, Playwright, and Chromatic for visual regression testing.
• UI: Updates in near real-time using WebSockets and WebRTC, styled via CSS modules, and performance-tuned with route-based code splitting and skeleton UI.
• Design System: Built on an extensive Storybook documenting our design system.
• Back-end: Python/Flask/FastAPI, MongoDB, Postgres, and Elasticsearch stack running on AWS.

Our Teams

• Agents: Build the UI that puts AI in the hands of Close customers. This includes creating and configuring Close's agents, the conversational interface, and observability surfaces.
• Communications: Own the UI for one of the most real-time, high-stakes surfaces in Close: calls. This involves building in-call experiences, live transcript and coaching views, power dialing flows, and email, SMS, and scheduling surfaces.
• CRM: Build the core surfaces that salespeople and agents depend on: lead pages, pipeline views, smart search, activity feeds. Focus on making these interactions fast and delightful while adding AI-powered features.
• Growth: Own the surfaces that turn someone who just signed up into a paying customer who sticks around. This includes onboarding flows, activation moments, billing and checkout UI, and the import experience.

About You

A seasoned frontend engineer with experience in React, Vue, Svelte, or Solid. You pick the right tool for the problem and can collaborate and self-direct. You've shipped LLM-backed features for real users and have a strong understanding of where AI is trustworthy and where it falls over. You use AI tools in your own workflow to ship faster and write tighter code. You're a builder first, willing to ship early iterations and debug performance regressions in production.

Benefits

• Compensation: Competitive pay plus an organization-wide goal-based bonus.
• Paid Time Off: ~5 weeks of PTO to start, plus a 1-week all-company Winter Holiday Break and paid US holidays. Earn 2 extra days for every year you're with Close.
• Work Option: 80% Work Option: Work with your manager to choose between a standard 5-day week or a 4-day week at 80% pay.
• Parental Leave: Paid leave for primary and secondary caregivers.
• Sabbatical: A 1-month paid sabbatical every 5 years with the team.
• Healthcare: US residents receive two medical plans with Close covering 99% of your premium, plus Dental, Vision, HSA, FSA, and company-paid Long-Term Disability.

Hiring Process

We ask a few role-specific questions as part of our application process. These questions are designed to help us learn more about you from the start. We see this as an opportunity to get to know you beyond your resume. We use AI tools daily at Close and expect candidates to do the same. In evaluating your application, we aim to get a sense for you - the way you think, how you communicate, the work you've done. Applications that read as fully AI-generated will not be considered. Regardless of fit, you can expect to hear back from our team with an update on the status of your candidacy. If you progress to the interview process, you'll receive a full outline of the role-specific steps in your first touchpoint with us. We do our best to make the hiring process clear and human.
