As a Frontend Engineer in Conversions, you will build personalized web experiences that help users find the right path through our funnels. You will focus on tailoring our user journeys based on user intent, channel and campaign data, using React, Next.js and edge environments. You will integrate with our CMS, work with experimentation frameworks, and use AI powered tools like Cursor, Figma and Contentful MCPs to speed up design, development and testing workflows. You will collaborate with machine learning, product and design teams to deliver fast, relevant experiences. You will also play a key role in performance, keeping Core Web Vitals strong and ensuring our personalization layer remains reliable and fast across mobile and desktop. Above all, we want people who make the team stronger. Even if you do not meet every requirement, we would still like to hear from you.

Lettuce Share What This Role Will Be Responsible For





Build and maintain personalized landing pages and funnel steps using React, TypeScript and Next.js

Work across frontend and infra tasks, including Cloudflare Workers, cache rules and Vercel Edge functions

Integrate dynamic content and variations coming from our CMS

Implement and validate A/B tests with Statsig, ensuring clean tracking and test integrity

Ensure strong performance on mobile and desktop, focusing on Core Web Vitals and low latency personalization

Implement and monitor frontend performance and error tracing using tools like Sentry and Honeycomb

Work with SSR and modern rendering patterns in Next.js to balance performance, caching and personalization

Use AI tools to speed up development, UI building and content workflows

Work closely with product, machine learning and design teams to shape current personalized experiences

Own features end to end, from design to rollout, monitoring and iteration

Work beyond your specialization when the problem demands it. Your specialization is your anchor, not your boundary.

Operate what you build. You instrument, monitor, and improve your systems in production. Shipping is the beginning of the learning cycle, not the end.

Sound a-peeling? Here’s what we’re looking for

Hands-on experience working with AI tooling (e.g., Claude Code, Cursor, Copilot)



beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.

You have product sense and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.

Solid experience with React, TypeScript and modern frontend development, including strong debugging skills across frontend and infra logic

Hands on experience with Next.js and edge runtimes like Vercel Edge or Cloudflare Workers

Good understanding of caching strategies and how they affect personalization and performance

Experience with web performance and frontend monitoring, including Core Web Vitals, Sentry, Honeycomb or similar tools

Experience writing and maintaining tests at different levels, including unit, integration and end to end

Experience integrating with a CMS, for example Contentful or Builder.io

Experience with A/B testing frameworks (e.g. statsig, optimizely)

Familiarity with analytics platforms like GA4 or Snowplow

You take full ownership. You have a bias to ship. You finish the last twenty percent.
