Principal Digital Experience Engineer - Supermetrics

We’re looking for a Principal Digital Experience Engineer to join our Marketing team in Helsinki, Dublin, Amsterdam, or the UK. Our website is our most important marketing asset — it’s where pipeline starts, where brand perception is formed, and where every campaign and paid media dollar ultimately lands. We need a recognized authority who can decide what should be built, why, and how — someone who sets the technical strategy for our entire web presence and is accountable for the outcomes. This is a Principal-level individual contributor role (IC5). You’ll make architectural decisions, define engineering standards, influence senior leadership, manage external partners, and shape how the organisation thinks about digital web experience as a growth lever. The stack: Astro.js, TypeScript, Sanity (headless CMS), integrated with HubSpot, Google Tag Manager, Google Analytics, and Zendesk. The strategic responsibilities you’ll own include end-to-end technical strategy, website builds and redesigns, foundation for conversion optimisation, site performance, data layer, content infrastructure, AI strategy, external partner management, and strategic influence. You’ll also get hands-on in code when it matters, including writing and reviewing TypeScript, Astro.js components, and Sanity integrations, managing deployments, monitoring performance, and implementing AI features. You’ll mentor colleagues, share knowledge, and collaborate across departments. Requirements include 12+ years of web development experience, deep expertise with Astro.js and Sanity, experience leading major website projects, designing experimentation infrastructure, understanding technical SEO, headless CMS architecture, analytics, and AI tools, with the ability to influence leadership and communicate technical trade-offs. This is a strategic leadership role focused on outcomes, not product development or content creation. Benefits include competitive compensation, equity, remote work allowance, healthcare, personal learning budget, and wellbeing allowance.
