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.
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
- 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
- Monitoring and optimising Core Web Vitals and mobile performance — diagnosing and resolving issues that require deep technical expertise
- Implementing AI-driven features where you need to evaluate feasibility, set the approach, or prove the concept before handing off
- Building the first version of content models, ingestion pipelines, or integration patterns that engineers across departments will extend
How You’ll Raise The Bar
- Mentoring and coaching colleagues at all levels on web best practices, modern development approaches, and AI tooling — acting as a role model across the organisation and potentially the broader industry
- Sharing knowledge proactively through documentation, internal sessions, and external contributions
- Collaborating as a credible technical peer with product and platform engineering teams across departments — not just marketing colleagues
This position is for you if you have
- 12+ years of professional web development experience, with at least 5 years in B2B SaaS at a senior or principal level
- Deep, hands‑on expertise with Astro.js and Sanity; candidates from a Next.js or similar TypeScript‑first framework background will be considered provided they can demonstrate Sanity depth and a clear path to ramping up on Astro
- A proven track record of leading major website projects with significant strategic and organisational implications — not just building, but deciding what gets built and being accountable for the outcome
- Experience designing experimentation and personalisation infrastructure — A/B testing frameworks, dynamic content delivery, and the architectural patterns that enable growth teams to move fast at scale
- Strong understanding of technical SEO at a systems level — architecture, rendering strategies, structured data, and crawlability — approached as an engineering discipline that creates compounding gains
- Strong experience with headless CMS architecture — ideally Sanity, but Contentful or equivalent is relevant. Comfortable designing content models, reusable modular blocks, and COPE content pipelines
- Deep experience with the web analytics and tracking layer — event architecture, GTM, and data collection implementation
- Experience integrating with marketing automation and analytics platforms (e.g., HubSpot, Marketo, Segment, Google Analytics/GTM)
- Significant experience working within and actively improving structured engineering workflows — version control, branching strategies, PR review processes, deployment pipelines, and incident management
- Proven ability to collaborate as a credible technical peer with product and platform engineering teams across departments
- Practical, daily use of AI development tools (Cursor, GitHub Copilot, Claude, etc.) and experience implementing AI‑driven site features with measurable outcomes
- Demonstrated ability to influence senior leadership and external stakeholders through technical expertise and strategic thinking
- A track record of developing new approaches, methodologies, or standards that have been adopted across an organisation or recognised within the industry
- The ability to communicate technical trade‑offs in plain language to non‑technical stakeholders and influence decision‑making at all levels
To be clear about what this role is and isn’t
- You won’t be responsible for product/application development — this is a marketing‑focused role
- You won’t be writing content or designing creative — you’ll work with content and design teammates to bring their work to life on the web
- You won’t be doing basic maintenance tickets daily — but if something is broken, you don’t leave it unfixed
- You won’t own data analysis, reporting, or conversion and growth strategy — you’ll be the authoritative technical voice responsible for technical execution and strategic technical leadership
Benefits We Offer
- Competitive compensation package, including equity
- Great work equipment and home office allowance for those in fully remote locations
- Health care benefit and leisure time insurance
- Annual €1,000 personal learning budget
