Our website is our most important marketing asset — where pipeline starts, brand perception forms, and every paid dollar lands. We are looking for a Principal-level engineer to own the technical strategy for it, end to end. You'll make architectural decisions, set engineering standards, manage external partners, and shape how the organization thinks about digital experience as a growth lever.

- 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 personalization, 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.)
