Own the strategic direction of a high-performance B2B SaaS website — and set the standard for how marketing websites drive revenue.

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 don’t need another strong engineer who can build things. We need a recognised 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. You can and will get your hands dirty in the code when it matters — but your primary value is strategic ownership, technical authority, and the judgment to know where your time creates the most leverage.

The stack: Astro.js, TypeScript, Sanity (headless CMS), integrated with HubSpot, Google Tag Manager, Google Analytics, and Zendesk.

THE STRATEGIC RESPONSIBILITIES YOU’LL OWN…

\* End-to-end technical strategy for the marketing website — platform, stack, infrastructure, and architecture decisions that you make and are accountable for at the organisational level

\* Website builds and redesigns from strategy through launch — you define technical requirements, set engineering standards, oversee delivery, and ensure the final product meets performance, accessibility, and brand standards

\* The technical foundation for conversion optimisation and experimentation — designing site architecture where A/B testing, personalisation, and rapid iteration are first-class capabilities. You enable the growth team to move fast; you’re not the person running the tests

\* Site performance, Core Web Vitals, uptime, and technical SEO health — developing and documenting performance methodologies that become organisational standards

\* The website data layer — defining event architecture and tracking standards that feed the broader BI strategy, working with Data Architects and Analysts

\* Content infrastructure strategy in Sanity — designing content models, reusable blocks, and ingestion pipelines that enable a “Create Once, Publish Everywhere” approach across the organisation

\* AI strategy for the website — evaluating and championing where AI-driven personalisation, dynamic content, conversational interfaces, and intelligent search can measurably improve the visitor experience or conversion rate

\* External partner management — briefing agencies and contractors, reviewing output quality, and making strategic build-vs-buy decisions

\* Strategic influence — shaping how senior leadership and external stakeholders think about web as a growth lever, bringing data-backed recommendations, and influencing decisions well beyond your immediate scope

WHERE YOU’LL ROLL UP YOUR SLEEVES…

You’re not above the code — you’re selective about when you’re in it. You’ll get hands-on when the work is high-stakes, architecturally significant, or when you need to set the standard that others will follow. In practice, that looks like:

\* Writing and reviewing TypeScript, Astro.js components, and Sanity integrations when the work is foundational or sets a pattern for others

\* Managing deployments through GitHub, owning code quality for critical paths, and defining the engineering practices and documentation that keep the site resilient
