Experience with headless or hybrid CMS platforms on top of a Next.js front end is important. * A track record of measurable outcomes: site rework that lifted conversions, publishing systems that cut creation time, tracking work that improved ad efficiency. * Hands-on experience with the marketing data layer: Google Analytics, Google Tag Manager, server-side tracking, and attribution. * Experience integrating marketing automation platforms and CRMs, HubSpot especially, and building custom middleware where off-the-shelf connections fall short. * Strong instincts for web performance and conversion, and the judgment to know when to build custom and when to buy. * Experience using AI agents and tooling in your development workflow, and interest in pushing that further. * Comfort owning a domain solo in a fast-moving environment: you set the technical direction, define the process, and ship., * Would describe yourself as being relentlessly resourceful. * You have a strong internal sense of urgency. You have a bias towards doing things today, rather than tomorrow. * Experience working in a startup environment is preferred but not required. * Are excited about the adventure of building a company! ## Description At Ivo you will work on challenging problems with colleagues who have high standards for each other, move fast, and care deeply about their craft., * This is a builder role. You'll own the architecture, development, and maintenance of a high-traffic website. * Lead a move from Webflow to a modern code-based stack, owning the migration and resulting architecture during the process. * Build a landing page and publishing system that lets marketers create and ship pages at scale without engineering involvement. * Build and run a component-level A/B testing and experimentation framework, integrated with our analytics stack. * Architect server-side tracking pipelines across ad platforms such as Google, Meta, LinkedIn, and Reddit, increasing tracking coverage and improving how we optimize spend. * Develop API integrations and middleware connecting the website to HubSpot, Salesforce, analytics tools, and the Ivo product, including sign-up flows that pass user data cleanly from first touch into the app. * Own site performance, core web vitals, and technical SEO, and maintain privacy compliance across consent management and tag governance. * Build AI-driven web tooling and workflows, from AI-assisted editing and publishing to agentic automation in the development process. * Develop interactive components and polished front-end experiences in partnership with design, holding a high bar for craft.
