Fullstack Engineer (Frontend Focus)

About the Role

We're looking for a frontend-leaning full-stack engineer to join a small, fast-moving team building and optimizing direct-to-consumer sales funnels. You'll own features end-to-end: from building landing pages and checkout flows to wiring up analytics, A/B tests, third-party integrations, and the server-side logic behind them.
This is a high-ownership role. You'll work in a modern full-stack codebase deployed on a serverless platform, touching everything from UI components to server-side routing, API endpoints, and data integrations.

What You'll Do

• Build and maintain conversion-optimized landing pages, product pages, and checkout flows
• Build and maintain server-side routes, API endpoints, and serverless functions (order processing, webhooks, third-party API calls)
• Integrate and manage third-party scripts and services: tag managers, analytics pixels, A/B testing tools, accessibility widgets, and payment SDKs
• Implement and debug tracking events across the funnel
• Handle secure server-side integrations with payment providers, commerce platforms, and internal services (API keys, tokens, webhooks)
• Work with marketing and growth teams to ship experiments quickly and iterate based on data
• Maintain code quality and reliability in a production codebase that handles real revenue

What We're Looking For

Must-have:

• Strong JavaScript/ES6+ fundamentals
• Experience with a modern component framework (React, Vue, Svelte, or similar), or eagerness to learn
• Comfort building backend logic: server-side routing, REST APIs, serverless functions, and working with webhooks
• Familiarity with e-commerce concepts: funnels, upsells, order bumps, checkout flows
• Comfort working with third-party scripts and browser APIs (cookies, local Storage, data Layer)
• Experience deploying to an edge/serverless platform

Nice-to-have:

• Experience with headless commerce or major e-commerce platforms
• Familiarity with tag managers, analytics tools, or marketing analytics pipelines
• Understanding of A/B testing concepts and tools
• Experience with databases and handling sensitive data (payments, PII) securely

What to Expect

• Small team, fast pace, PRs ship to production frequently
• Real ownership over your work, front to back; you'll see the impact of your changes in conversion data
