[Remote] Full Stack Engineer, Growth

Note: The job is a remote job and is open to candidates in USA. Triple Whale is an AI operating system designed for modern e-commerce, helping businesses optimize their performance through actionable insights. They are seeking a Full Stack Engineer to focus on growth surfaces, building experiences that drive customer activation and feature adoption, while also managing experimentation infrastructure and collaborating across teams.

Responsibilities

• You'll build the frontend experiences that drive self-serve conversion: upgrade modals, plan comparison views, usage limit messaging, gating experiences, and in-product CTAs. These need to feel native to the product, not bolted on. You'll work closely with product to design, test, and iterate on these flows based on real user behavior and experiment results
• You'll own the frontend side of the growth experimentation stack. This includes implementing feature flags, building A/B test variants, instrumenting events for analytics, and ensuring the team can run experiments quickly without shipping fragile code. You should be comfortable working with tools like LaunchDarkly, Statsig, or similar, or building lightweight equivalents when needed
• You'll build the in-product experiences that help new and existing customers hit activation milestones faster: guided flows, tooltips, checklists, contextual nudges, and feature education moments. The goal is to get customers to the value that makes them want to upgrade, not just to show them a paywall
• Growth decisions are only as good as the data behind them. You'll be responsible for ensuring clean, reliable event tracking across the growth surfaces you build so the team can measure activation, conversion, and feature adoption accurately
• While growth is your primary focus, you'll also contribute to core product work when priorities call for it. This keeps you connected to the broader product experience and ensures growth surfaces stay consistent with the rest of the platform

Skills

• 2+ years of professional full stack engineering experience with a frontend emphasis, primarily in React with backend experience in Node.js, Python, or similar
• Experience building UI that sits in the critical path of user conversion or monetization (upgrade flows, checkout, onboarding, paywalls, or similar)
• Hands-on experience with feature flagging and A/B testing infrastructure, whether through third-party tools (LaunchDarkly, Statsig, Optimizely) or custom-built systems
• Comfort with analytics instrumentation and event tracking (Segment, Amplitude, Mixpanel, or similar)
• Experience using AI tools (Cursor, Claude, Copilot, or similar) as a core part of your development workflow, not just occasionally
• Ability to move fast and ship iteratively without sacrificing code quality in the areas that matter
• Strong collaboration skills, especially working in a tight loop with product and using data to inform what you build next
• Experience building features that integrate AI/LLM capabilities (prompt design, API integration, streaming responses, or similar)
• Experience at a product-led growth company or on a dedicated growth engineering team
• Familiarity with in-app messaging or onboarding tools (Appcues, Pendo, Intercom Product Tours, or custom equivalents)
• Experience in ecommerce, marketing technology, or ad tech
• Interest in the 'why' behind what you're building, not just the 'how.' The best growth engineers care about the metrics, not just the code
