Website Manager (part-time)

SumUp • Boulder, CO

22h • Hybrid

About The Position

SumUp is a global financial technology company that helps businesses of all sizes accept payments and manage their business both in-store and online. We support millions of merchants globally across dozens of markets, and we’re building a world where everyone can build a thriving business. We’re looking for a part-time, hands-on Website Manager to support our US Growth & Marketing team. You’ll be the person who actually ships: publishing updates, keeping the site healthy, and implementing technical SEO requirements in Contentful and Builder.io.

Requirements

• 2-4 years of experience publishing/managing websites (in-house, agency, or freelance)
• Hands-on Contentful experience (strongly preferred)
• Hands-on Builder.io experience (preferred), or proven experience picking up a similar CMS/page builder quickly
• Practical technical SEO implementation experience (you’ve set metadata, fixed header hierarchy, improved internal linking, written alt text, etc.)
• Strong production instincts: accuracy, speed, file/content hygiene, and a reliable QA process
• Comfort collaborating with Marketing and Design stakeholders

Nice To Haves

• Basic HTML/CSS literacy (enough to understand what’s happening and communicate clearly)
• Familiarity with Core Web Vitals/performance basics (image weight, page speed hygiene)
• Familiarity with evolving search trends, including AI-driven and answer-based search experiences
• Experience supporting a CMS migration or large site refresh
• Experience working in multi-locale environments or with localization workflows

Responsibilities

• Publish, update, and maintain pages in Contentful and Builder.io (new pages, refreshes, page swaps, component updates)
• Implement technical SEO updates as part of publishing, including heading structure (H1/H2), metadata, alt text, and internal linking
• QA changes before and after launch: responsive checks, link checks, formatting/layout checks, and basic accessibility hygiene
• Troubleshoot CMS publishing issues
• Support ongoing website workstreams like Builder adoption/migration by executing the “last mile” implementation work
• Maintain a lightweight backlog of site fixes and improvements (broken links, outdated copy swaps, missing metadata, etc.)
• Keep simple documentation/checklists so publishing and SEO execution stays consistent and scalable

Benefits

• A global team with a scrappy, high-ownership culture
• A fast-moving marketing team where your work will ship, not sit in a queue
• Visible impact: your work directly improves site quality, speed to market, and organic performance
