Principal Digital Experience Engineer (Marketing), Dublin Pike

Requirements

12+ years of web development experience, with at least 5 years at senior or principal level in B2B SaaS

Practical Astro.js and Sanity experience; Next.js/TypeScript backgrounds considered with strong Sanity proficiency

A track record of guiding major web projects end-to-end— architecture through launch — with rigorous engineering workflows: version control, PR reviews, deployment pipelines, and incident management

Experience designing experimentation and personalisation platforms: A/B testing systems, dynamic content delivery, and scalable growth architecture

Technical SEO and AI visibility knowledge at the systems level, plus deep analytics and tracking experience across GTM, event architecture, and platforms like HubSpot, Marketo, and Segment

Daily use of AI development tools (Cursor, GitHub Copilot, Claude, etc.) and a track record of shipping AI-driven site features

The ability to communicate technical trade-offs clearly to non-technical stakeholders

What the job involves

Our website is our most important marketing asset— where pipeline starts, brand is formed, and every campaign dollar lands

We need a Principal-level architect who sets our technical direction rather than taking tickets: an elite engineering mind who understands that code is a lever for revenue

You’ll work on a stack built on Astro.js, TypeScript, and Sanity, integrated with HubSpot, GTM, Google Analytics, Intercom, and Zendesk

Own the systems architecture for our marketing website— authoritative decisions on platform, stack, infrastructure, and performance, with daily hands-on work in the codebase

Design the technical foundation for experimentation at scale: A/B testing frameworks, personalisation middleware, and rapid iteration pipelines

Architect the Sanity content infrastructure for a "Create Once, Publish Everywhere" workflow, including content models, reusable blocks, and ingestion pipelines

Own the website data layer, event architecture, and tracking standards; monitor and optimize Core Web Vitals, uptime, and technical SEO/AI visibility continuously

Prototype and deploy AI-driven features— personalisation, dynamic content, intelligent search — with AI tooling as a default part of your workflow

Provide technical oversight of external agencies and contractors: enforcing PR standards, CI/CD pipelines, and ensuring output meets our architectural bar

Bring data-backed recommendations to senior stakeholders, mentor colleagues, and raise the bar for web engineering across the organization
