Job description

About the role

This is a hands‑on development role that sits inside our SEO delivery team. The job is building and fixing websites. Most technical SEO problems live in the code, not in a strategy deck. You will open a live Webflow or WordPress site, understand exactly why it's misbehaving, and fix it — not just flag it in a report.

Key responsibilities

• Running and acting on technical SEO audits across client sites: broken pages, 3XX/4XX redirect issues, incorrect rel=canonicals, CCNI issues, missing or duplicate Open Graph tags, mixed‑content/HTTPS problems, crawl and indexation issues.
• Fixing these issues directly in the codebase — not just documenting them for someone else to action.
• Occasionally designing and building new pages or small sites, mostly in Webflow, sometimes WordPress.
• Writing custom HTML/CSS (and JS where needed) rather than relying entirely on visual builders, component libraries, or plugins.
• Integrating client sites with backend services (HubSpot, CRMs, forms, analytics).
• Working closely with our Technical SEO Manager on a rolling programme of client audits.
• Maintaining and scaling both our own site and client sites over time.

About you

• 4+ years building and maintaining live, production websites — front and back end.
• Genuine hands‑on Webflow experience: you can build a site from a blank canvas and understand what's happening under the hood, not just assemble Relume or library sections.
• Real WordPress development experience: you can diagnose and fix a theme, template, or server‑level issue without reaching for a plugin as the first response.
• Practical experience with tools like Screaming Frog, Google Search Console, and Ahrefs — used to diagnose problems that you then go and fix in code.
• Solid HTML/CSS fundamentals and comfort reading and writing JavaScript.
• A working understanding of how redirects, canonicals, robots directives, sitemaps, and Open Graph/meta tags actually function, not just what they're called.
• Educated to degree level preferred, with strong written and spoken English.
• Strong communication and problem‑solving skills; comfortable explaining a technical fix to a non‑technical client.
• Good attention to detail and time management, and genuine curiosity about staying current with both web development and SEO/AI‑search developments.
