Technical Web Lead

About the role

This is a founding role. You will be the first engineering hire on the marketing team at Fireworks AI: the person who owns the web platform end-to-end, and who brings the technical credibility to everything marketing builds online.

What You’ll Do

• Own the architecture and health of the Fireworks marketing web platform: a Next.js 15 monorepo with shared component libraries, Sanity Studio, and Vercel hosting.
• Evolve and scale the existing Sanity content architecture, improving content modelling, GROQ queries, and dataset structure to give marketing, digital, and growth teams greater independence.
• Lead the technical execution of the web refresh, setting direction, defining milestones, and keeping the project on track without a dedicated PM.
• Work alongside the agency partner on technical strategy and delivery, reviewing output, translating briefs, and holding work to a high standard.
• Manage Vercel deployment workflows, ISR revalidation, preview environments, and third-party integrations including Mux, HubSpot, and GitHub Actions pipelines.
• Drive performance best practices across Core Web Vitals, Lighthouse, caching, accessibility (WCAG), and SEO.
• Partner with Marketing Operations on martech integrations and tooling, and collaborate with Digital and Growth on experimentation, landing pages, and analytics.
• Communicate progress, decisions, and trade-offs clearly to non-technical stakeholders and leadership.

The Stack

• Next.js 15 (React) with TypeScript, monorepo via Turborepo + Yarn workspaces
• Sanity Studio v3, GROQ queries via groqd, production and staging datasets
• Vercel with ISR and on-demand revalidation
• Mux Video
• HubSpot CRM / Forms
• GitHub Actions Pipelines
• external agency Execution partner

What We’re Looking For

• 6-8+ years of professional experience in full-stack or frontend-heavy web development.
• 4+ years of production experience with React and Next.js, including SSR, SSG, app router, and performance optimisation.
• Strong fluency in TypeScript and modern JavaScript (ES6+).
• Deep experience with Sanity or a comparable headless CMS, including content modelling, GROQ, structured data, and composable architecture.
• Proficiency with Vercel: deployments, ISR, edge functions, preview environments, and environment management.
• Solid grasp of Core Web Vitals, Lighthouse performance auditing, and frontend performance tuning.
• Familiarity with CI/CD pipelines and GitHub Actions.
• Experience managing third-party integrations (video hosting, CRM, marketing tooling).
• Proven ability to manage an external agency or vendor: directing, reviewing, and holding partners accountable.
• Strong project management instincts: you can own delivery end-to-end without a dedicated PM.
• Clear, direct communicator, equally comfortable writing a technical spec and presenting trade-offs to marketing leadership.
• Comfortable operating autonomously in a small, fast-moving environment where priorities shift and pace is relentless.

Nice to Have

• Experience improving and scaling an existing web platform, ideally on a headless CMS and Jamstack stack.
• Familiarity with marketing analytics platforms: GA4, Segment, PostHog, Adobe Analytics, or similar.
• Hands-on experience with HubSpot integrations or similar CRM/marketing automation tooling.
• Experience with automated testing frameworks (Jest, Cypress, Playwright).
• Familiarity with monorepo tooling such as Turborepo or Nx.
• Familiarity with AI or developer-tooling products (bonus for Fireworks-adjacent domain knowledge).
• Experience in a founding or first-in-function role at a startup or scale-up.
