Principal Digital Experience Engineer Job at Supermetrics (Dublin)

Job Description

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.

Job Responsibility

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
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

Requirements

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
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
Strong experience with headless CMS architecture — ideally Sanity, but Contentful or equivalent is relevant
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

Great work equipment and home office allowance for those in fully remote locations
Health care benefit and leisure time insurance
