Experience implementing OAuth/OIDC flows and managing user sessions behind login walls (Auth0, FusionAuth, or similar).
Proficiency with Headless CMS platforms (e.g., Contentful, Sanity) and marketing automation integrations (HubSpot, Segment).
A pixel-perfect design sensibility — comfortable in Figma and capable of translating complex data visualizations into clean, responsive web components.
Strong communicator who can collaborate across teams, explaining technical trade-offs to marketing stakeholders while holding your own in architectural reviews with core platform engineers.

Responsibilities

Spearhead the development of our high-traffic marketing sites, ensuring these platforms are not just visually stunning but technically optimized for rapid content publishing.

Own Core Web Vitals to ensure lightning-fast load times.
Maintain the sophisticated walls between our free and premium content, integrating with our Auth provider and subscription management tools to create frictionless transitions from guest to subscriber.
