• Capstone project mentors who help students design and scale leadership initiatives with real-world impact, measurable outcomes, and credible external validation

We now operate across 21 markets worldwide, including the US, Canada, UK, Singapore, Japan, Hong Kong, Australia, and New Zealand.

The Role

We're hiring a Full Stack Engineer to own our marketing website and the tracking and attribution behind it. You'll be building functionality, attribution and tracking in a large enterprise system.

You'll play an integral role in shaping the architecture of our systems and implementing them, working closely with marketing, data and product.

What you'll work on

• Website: Build polished, high-quality UI across our multi-locale headless website on Next.js, Vercel and Storyblok, from components and forms to landing pages and content tools. You'll care as much about how it looks and feels as how it works.

• Technical SEO: Own site architecture, metadata, structured data, sitemaps, robots, hreflang and redirects across every locale.

• Performance: Implement our caching and rendering roadmap (ISR, edge, CDN) so pages stay fast in every region we serve.

• Analytics and attribution: Own analytics and conversion tracking across web and ad platforms, ensuring data is accurate, reliable and trusted for decision making.

• Integrations: Build and maintain Node.js APIs and webhooks that connect our forms to automation tools, CRM, Supabase and Snowflake.

• Monitoring and testing: Run automated tests and monitoring that catch broken forms, tracking gaps and lost leads before marketing or sales notice.

• Martech systems: Build and improve the systems behind our lead flow, such as auto-prioritisation flows, dedupe logic and attribution inserts.

• Documentation: Keep clear, current docs for everything you own, using AI to make that easy.

Success looks like

• Attribution you can trust: Every lead carries the right source, UTMs and click IDs, and ad platform conversions reconcile with the CRM.

• No silent failures: Broken forms, tracking or integrations get caught by monitoring within hours, not found by sales weeks later.

• Fast pages: Key templates pass Core Web Vitals and load in under 2 seconds across target regions.

• Strong SEO foundations: Clean, indexable architecture across all locales, with no regressions from releases.

• Documented systems: Anyone on the team can pick up what you've built from the docs.

Roadmap delivered: Martech roadmap work ships on time and cleanly replaces old flows.

You'll need

5+ years of commercial full stack experience, equally strong on front end and back end

• Strong React, Next.js, Node.js and TypeScript

• A strong eye for UI: you turn designs into beautiful, responsive and accessible interfaces, and sweat the details

• Production experience on Vercel, including caching, ISR, edge middleware and preview workflows

• Experience on a large headless website or product, ideally with a headless CMS like Storyblok, Sanity or Contentful

• Deep technical SEO knowledge, with sites you can point to

• A track record of setting up accurate analytics and attribution: GTM, GA4, server-side tagging or conversion APIs, UTM and consent handling

• Strong web performance skills: caching, CDNs, rendering strategies and Core Web Vitals

• Comfortable building with AI tools like Claude Code or Cursor in your day-to-day, while reviewing and testing everything you ship

• Clear writing and good documentation habits

• Based in New Zealand or Australia with full working rights, and comfortable working async across time zones

Nice to have

• Worked in an engineering team where a good share of code is AI-generated, with solid review practices around it

• Marketo, Salesforce or other marketing automation and CRM APIs

• Meta CAPI, Google Ads offline or enhanced conversions

• Supabase or Postgres, Snowflake, Metabase

• Multi-locale sites (i18n, hreflang)

• High-volume lead gen or EdTech experience
