About FX Replay

FX Replay helps over 1 million traders practice, test strategies, and improve their trading through market replay and backtesting.

We're looking for a Growth Engineer to help our Growth team turn ideas into live, measured experiences on our website.

About the role

This is not a traditional marketing role, and it is not a core product engineering role.

You will work at the intersection of web development, growth, analytics, infrastructure, and AI-assisted implementation. You take a bet from hypothesis to production: you read the data, build the page or the variant, connect the systems behind it, instrument it, launch the test, and report what happened.

Most of our implementation already runs through AI agents connected to our tools. We need someone who can lead that workflow technically, keep it reliable, and make it faster with every launch.

How we ship today

Every growth change follows the same path, and you will own the technical side of it:

- Data:



Baselines and opportunities from GA4 and BigQuery.
- Bet: Problem, falsifiable hypothesis, primary KPI, guardrails, rollout and rollback plan, documented in Notion.
- Copy and design: StoryBrand messaging and Figma variants, read by agents through the Figma MCP.
- Build: Implementation in Ploy (Astro, React, TypeScript) with Claude and MCP servers, governed by Ploybooks and a Notion-based CMS.
- Test: A/B tests in Convert, with variant IDs sent to GA4 and guardrails on PageSpeed, CLS, and bounce rate.

What you'll own

- Build and evolve landing pages, campaign pages, pricing experiences, forms, thank-you pages, and conversion flows in Ploy.
- Turn Figma designs and variants into production pages using AI agents and MCP integrations, and review every output with a developer's eye before it goes live.
- Implement and QA A/B tests end to end: setup, targeting, goals, flicker and performance checks, launch, and the final read.
- Integrate CRMs, forms, email sequences, APIs, and marketing platforms (HighLevel, Meta, and similar) with the website.
- Protect critical functionality, including checkout, pricing logic, authentication, tracking scripts, and consent, so a fast launch never breaks what already works.
- Own technical SEO, Core Web Vitals, accessibility, and performance on growth pages.
- Operate the supporting infrastructure: DNS, hosting, cloud servers (AWS, DigitalOcean or similar), SSL, deployments, and monitoring.
- Build reusable components, templates, and agent instructions so each new page or test takes less time than the last.
- Bring or
