The role involves owning the marketing website and collaborating with various teams to enhance the user experience and drive business objectives.

Responsibilities:

• Set the technical direction for the CMS and component system — clear architectural boundaries, consistent guardrails, and a foundation that lets marketing and design move fast without fragility
• Enhance and maintain a release and QA discipline: rollback processes, staging environments, and deployment confidence
• Own Core Web Vitals and page speed performance as a first-class concern — and help connect them to measurable conversion rate impact
• Own analytics instrumentation an event taxonomy governance — the technical source of truth for what's happening across the funnel
• Build reusable components and page patterns that make new landing pages and campaigns quick to stand up without one-off engineering lifts
• Maintain and extend A/B testing setup so Marketing team can run clean experiments on those pages at velocity
• Partner with Brand, Design, and Marketing to translate campaigns, landing pages, and brand work into production web code — fast, pixel-faithful, and performant
• Own the technical quality of what ships: accessibility, Core Web Vitals, SEO fundamentals (schema, rendering, structured data), and cross-browser/device behavior
• Be the engineering partner Marketing, Growth, and GTM teams rely on to move fast without breaking the pipeline
• Enable self-serve content workflows through CMS so creative teams can publish without engineering bottlenecks
• Collaborate with GTM and Rev Ops to maintain guardrails on form and routing decisions that affect lead flow reliability

Requirements:

• 5+ years of professional software engineering experience with a meaningful amount of it focused on web frontend or marketing engineering
• Experience working with a headless CMS or visual editor (Contentful, Builder.io, Webflow, or similar)
• Solid foundation in HTML and CSS — you understand the DOM, can debug layout issues without a framework crutch, and take accessibility (a11y) seriously
• Strong command of TypeScript/JavaScript and React — you write clean, maintainable code and you care about the difference
• Hands-on experience with Next.js — you understand SSR, SSG, ISR, and when to use which
• Deep familiarity with web performance: Core Web Vitals, Lighthouse, lazy loading, bundle optimization
• Comfort with full-stack work: REST APIs, serverless functions, data pipelines, and integrations with third-party services
• Systems thinker who can hold the big picture (platform strategy, cross-functional dependencies) and the details (a broken event tag, a slow LCP) at the same time
• Strong communicator: you can translate technical constraints into plain language for marketing and GTM stakeholders, and you know when to push back
• Prior work at a B2B SaaS or PLG company where the website directly supported both self-serve and sales-led motions
• Experience with experimentation platforms (LaunchDarkly, Eppo, or custom frameworks)
• Familiarity with marketing analytics and GTM tooling (Amplitude, Segment, Google Tag Manager, Salesforce integrations)
• Background in technical SEO — schema markup, crawl optimization, rendering strategy
• Experience with lead enrichment and inbound routing platforms (Default, Clearbit, RB2B, or similar)
