Job description

Help craft the online experience for top-tier B2B SaaS companies — and set a higher standard for modern marketing websites. 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.

Responsibilities

• 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 optimise 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 organisation

Qualifications

• 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

Benefits

• Competitive compensation package, including equity
• Great work equipment and home office allowance for remote locations
• Health care benefit and leisure time insurance
• €1,000 annual personal learning budget
• Sports and wellbeing allowance

We are committed to providing a welcoming and inclusive workplace for all. We believe that a diverse workforce is a strong workforce, and we are dedicated to creating an environment where everyone feels valued and respected.
