About the role
Senior Web Engineer
Architect high-performance web experiences for top-tier B2B SaaS—and set the new technical standard for modern marketing sites.
Our website is our most important marketing asset — where pipeline starts, brand is formed, and every campaign dollar lands. We need a web engineer 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.
What you will do
- Own the systems architecture for our marketing website — authoritative decisions on platform, stack, infrastructure, and performance, with daily hands-on work in the codebase
- Prototype and deploy AI-driven features — personalisation, dynamic content, intelligent search — with AI tooling as a default part of your workflow
- 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
- 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 and colleagues, and raise the bar for web engineering across the organization
