Front-End & Growth Engineer

Description

**Front\-End \& Growth EngineerThe Role** We're looking for someone who can take designs live and own the full experimentation loop, from building and launching A/B tests to measuring whether they worked. This is an implementation\-first role with real engineering depth. You'll work across Webflow, Heyflow, run experiments in VWO, wire up tracking and lifecycle events (Klaviyo, BigQuery), and close the loop with reporting that actually drives decisions. We have a strong preference for someone who can operate end\-to\-end. You'll have a full stack developer to collaborate with, but the less you depend on them, the better. **Time commitment:** Flexible and as\-needed. We'll be upfront about upcoming projects; we expect the same in return. **What You'll Do** **Implementation** * Translate Figma designs into pixel\-perfect, responsive experiences in Webflow and Heyflow * Build and maintain pages, funnels, and interactive components across platforms **Experimentation \& CRO** * Set up and run A/B tests in VWO, including pricing tests, cross\-sell/upsell offers, and conversion funnel experiments * Partner with head of growth to define the right metrics before a test launches, capture them correctly, and declare winners based on data **Tracking** * Capture new events (e.g., marketing consent) and maintain a clean, reliable tracking layer * Instrument tracking via GTM across Google Ads and/or Google Analytics depending on the needs of each test. **Lifecycle** * Instrument events via GTM and pass them correctly into Klaviyo and BigQuery * Support lifecycle triggers and cross\-sell/upsell flows in Klaviyo **Analytics \& Reporting** * Build and maintain dashboards (from BigQuery) that show funnel performance and experiment results **Skills** **Need To Have** * HTML, CSS, JavaScript, strong fundamentals, not just platform familiarity * Webflow (CMS, responsive design, custom code) * VWO or equivalent A/B testing platform * Browser internals: cookies, URL params, session/local storage, and how they interact with tracking * GTM and advanced event tracking * BigQuery and SQL, enough to model experiment metrics and build dashboards * Klaviyo, event passing, flow logic * Cross\-browser/device QA **Prefer Candidates That Also Have** *(the more of these, the more you can own end\-to\-end)* * TypeScript and Next.js * Stripe, pricing, checkout, subscription flows * Google Cloud (Cloud Run, Pub/Sub) * Heyflow * Golang and Temporal.io * Figma **Who You Are** * **Detail\-oriented and disciplined about QA**: you don't ship until it's right, and "right" includes the tracking, not just the UI * **End\-to\-end by default**: you don't hand off the measurement side of a test and hope for the best; you own the loop * **A natural problem solver**: unfamiliar tool, messy tracking setup, design that doesn't translate, you figure it out * **A clear communicator**: you flag issues proactively, propose solutions, and keep stakeholders in the loop without being prompted * **Driven by evidence**: you ship to learn, not just to ship; you care whether the thing you built actually worked Job Type: Part\-time Pay: R$200\.00 \- R$250\.00 per hour Application Question(s): * What got you interested in the role? * Have you done similar work for growth marketing teams? If so, can you describe some projects you worked on that align with what we're looking for please? * What's your overlap with the skills required? What are you very familiar with / where are you less familiar? * What's your current availability look like? We are looking to understand days/times of week. * Can you please share a link to your github profile if you have one? Work Location: Remote
