Senior Software Engineer – Marketing (USA Only & 100% Remote)

About the role

One of our values is “Build a house you want to live in.” In this metaphor, Close.com is the front door. Our website is where people learn about who we are, what we do and, even more importantly, it’s a critical touch point on their journey to becoming a Close customer. We’re dedicated to making it best-in-class. We’ve recently migrated from Webflow to our own codebase (Astro, Sanity, Vercel) so a new and improved foundation is in place. We believe building in-house gives us the flexibility, creativity, and speed to make our website a competitive advantage.

What you’ll own

• Build and continuously improve a world-class marketing website that is responsive, highly interactive, and polished—bringing the product to life through animation and interactivity.
• Ship new pages and continue raising the bar on core site functionality.
• Make the site fast and findable by owning performance, technical SEO, and how the site shows up to search engines and AI agents.
• Manage the infrastructure behind the site: the platform (Sanity), components, integrations, and deployment.
• Own the technical integrity of site measurement and partner on experiments—ensure tracking, attribution, conversion events, and funnel data are implemented correctly and reliably flow into our marketing and data systems.
• Build tools that let Marketing self-serve and help the site self-improve: automations and flows to help the team ship pages, campaigns, and experiments, plus systems that catch regressions or flag performance problems and SEO issues.
• Act as an engineering resource to marketing—sometimes hopping in yourself, or just knowing when to loop in the right person.

Who you are

• You’re a tried-and-true marketing website engineer with 5+ years of experience building beautiful, conversion-focused websites.
• You’re fluent in modern stacks like Astro and headless CMSs (Sanity), and you sweat page speed and how the site reads to both search engines and AI agents.
• Motion, ambitious CSS, and rich media are second nature to you.
• You’re fluent in measurement: cookies, conversion events, analytics, and experimentation tooling (Segment, Amplitude, Customer.io, etc.).
• You’re focused on conversion and fueled by impact—your work will directly affect traffic, conversion, and revenue in a self-service SMB business.
• You’re energized by empowering non-technical teammates: you’ve built systems that let Marketers or Designers self-serve and solve problems quickly and independently.
• You already use AI to move faster and empower your team, but you’re equally discerning about when craftsmanship and taste are required.
• You’re resourceful and collaborative—you’ll bridge Marketing and Engineering and work easily with folks across departments and levels.

Benefits

• Compensation: Competitive pay plus an organization-wide goal-based bonus.

• Parental Leave: Paid leave for primary and secondary caregivers.
• Sabbatical: 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): Match up to 6%, vested immediately.
