Principal Web Engineer, Marketing
TLDR
Own the technical strategy for the marketing website, making architectural decisions and managing growth-oriented digital experiences.
Our website is our most important marketing asset — where pipeline starts, brand perception forms, and every paid dollar lands. We're looking for a Principal-level engineer who can own the technical strategy for it, end to end.
You'll make architectural decisions, set engineering standards, manage external partners, and shape how the organisation thinks about digital experience as a growth lever. You'll get your hands dirty in code when it's high-stakes or foundational — but your primary value is judgment, strategic ownership, and accountability for outcomes.
The stack: Astro.js, TypeScript, Sanity (headless CMS), HubSpot, GTM, Google Analytics, Zendesk.
What you'll own
- End-to-end technical strategy for the marketing website — platform, architecture, and performance
- Website builds and redesigns from requirements through launch
- Conversion optimisation and experimentation infrastructure — enabling the growth team to move fast
- The website data layer — event architecture and tracking standards that feed broader BI
- Content infrastructure in Sanity — content models, reusable blocks, and COPE pipelines
- AI strategy for the site — evaluating where personalisation, dynamic content, and intelligent search can move the needle
- External partner management and build-vs-buy decisions
What we're looking for
- 12+ years of web development experience, with 5+ years at senior/principal level in B2B SaaS
- Deep expertise with Astro.js and Sanity (or Next.js + demonstrable Sanity depth)
- Proven track record leading major website projects with strategic and organisational implications
- Strong experience with A/B testing architecture, technical SEO, headless CMS, and the analytics/tracking layer
- Ability to communicate technical trade-offs clearly to non-technical stakeholders
- Practical, daily use of AI development tools (Cursor, Copilot, Claude, etc.)
Benefits
- Competitive compensation including equity
- Home office allowance
- Health care and leisure time insurance
- €1,000 annual learning budget
- Sports and wellbeing allowance
