Role Overview

This role owns leena.ai website end-to-end: shipping website changes, standing up A/B testing, and driving conversion optimization. It also owns the initial PLG surface: improving the sandbox experience and building a lightweight product wedge that gives prospects self-serve value before a sales conversation.

Key Responsibilities

1. Website Changes & Page Development

• Own the leena.ai codebase (Next.js / React deployed on Cloudflare); ship new pages, redesigns, and campaign landing pages within days, not sprints.

• Implement responsive, accessible, and performant front-end code aligned with the Design team's specs.

• Build reusable page templates and component libraries so Marketing can compose pages with minimal engineering lift.

• Manage deployment pipelines, staging environments, and site reliability (uptime, Core Web Vitals, page speed).

2. A/B Testing Infrastructure

• Evaluate and implement an A/B testing infrastructure that can be integrated with the existing analytics stack.

• Build the plumbing: experiment assignment, event tracking, statistical significance reporting, and audience segmentation.

• Create a self-serve experimentation workflow so Marketing and Growth can launch, monitor, and conclude tests without engineering tickets.

• Document experimentation standards (sample size, run time, success metrics) for the team.

3. Conversion-Rate Optimization

• Instrument the full visitor funnel — landing → page scroll → CTA click → demo form submit → confirmation with event-level tracking (GA4, Segment, or equivalent).

• Analyze conversion data by page, traffic source, geography, and device to identify drop-off points.

• Run iterative experiments on headlines, hero sections, social proof, form fields, and CTA placement to improve demo-request conversion rate.

• Partner with the Marketing teams to close the loop from website lead to qualified pipeline, feeding learnings back into page design.

4. Sandbox & Product Wedge

• Own the Leena sandbox experience reduce setup friction, improve time-to-value.

• Build and iterate on a product wedge: a self-serve tool on leena.ai (e.g., HR ticket analyzer, automation ROI calculator) that uses Leena's domain model to deliver value a general-purpose LLM can't replicate.

• Instrument the wedge funnel; signups, activation, engagement, PQL conversion.

• Work with Product to define what "product-qualified" means and how wedge usage maps to enterprise buying intent.

Required Qualifications

• 1–3 years of professional front-end or full-stack web development experience.

• Strong proficiency in React and Next.js (SSR, SSG, API routes, image optimization).

• Comfortable with CI/CD workflows, Git, and deploying to modern hosting platforms (Cloudflare Pages/Workers, Vercel, or AWS).

• Light backend experience is a plus: our site runs on Cloudflare Workers, so experience writing edge logic, simple APIs, or redirects in JS/TS (Workers, Pages, KV/D1) helps

• Understanding of Core Web Vitals and performance optimization (Lighthouse scores, lazy loading, bundle splitting).

• Strong communication skills; able to work directly with Marketing, Design, and GTM stakeholders without a PM intermediary.

• Experience at a B2B SaaS or enterprise software company, especially in a growth or marketing-engineering role.

• Hands-on CRO experience; has personally run and analyzed multivariate tests that moved conversion metrics.

• Familiarity with headless CMS platforms (Contentful, Sanity, Strapi) for marketing-managed content is strongly preferred.

• Exposure to tools like Hotjar, FullStory, or Microsoft Clarity for session recording and heatmap analysis.

• Design sensibility; can translate a Figma comp to pixel-accurate, polished UI without heavy design oversight.

• Basic data/SQL skills for pulling conversion funnel data from a warehouse (Snowflake, BigQuery).
