You'll team up with the rest of the Growth teams to find what converts. With IT and R&D, you'll ship code that meets the same standards as our product. What you'll work on: Build * Product launches, events for 1,000+ attendees, interactive experiences, and campaign pages: you will own all the development of all the marketing web experiences. You'll take them from Figma to production with the web team, marketers, and design. * Own the Contentful content model and component library: content types, validations, references, and reusable sections. Design system first, always, so marketers can build pages without breaking design, forms, tracking, or SEO. * Ship code that's QAd and ready. You'll check it across devices, browsers, and tracking before anyone else has to. Optimize * Make pages fast and keep them fast. Core Web Vitals are your scoreboard. * Build A/B tests and personalized experiences with Growth and Paid. Read the results, ship the winner, run the next one. * Keep the technical SEO and AEO tight: structured data, redirects, hreflang, crawlability, and the files and markup that help AI systems read the site. Measure * Own tracking in Google Tag Manager across organic and paid, including taking over day-to-day tag maintenance from our external provider: the data layer, GA4 events, pixels, conversion APIs, and consent mode. * Spot the broken funnel or the attribution gap before anyone asks, and come up with the fix. Automate * Build AI agents into the release process: code-reviews, first-pass QA, accessibility checks, and link and metadata audits, so people spend review time on judgment calls. * Work with marketers and the growth team to embed them into agentic processes., * You don't wait for a ticket. If something is broken, slow, or manual, you fix it. * You can explain a tradeoff to a marketer, and you can say no to a launch that isn't ready. * You have a portfolio or GitHub you're proud of. * You're on the US East Coast (New York hybrid preferred) and happy to overlap with European mornings: the team spans Paris and the US. Nice to have * Next.js and Vercel. * A/B testing or personalization tools, especially Contentful Personalization (formerly Ninetailed). * Server-side GTM, consent management, Google Ads enhanced conversions, LinkedIn or Meta conversion APIs. * Technical SEO and structured data.
