You will be the architect and primary builder for everything related to user acquisition and revenue generation-from first click to subscription.\nThis is a high-impact role where your code directly translates to business metrics, focusing on dynamic funnel optimization, pricing strategies, A/B testing, and comprehensive analytics implementation.\nWhat You’ll Do (Core Responsibilities)\nYour primary focus will be on driving conversion across web and native platforms:\n Conversion Funnel Ownership: Design, develop, and own all B2C conversion assets, including dynamic pricing pages, registration funnels (which includes the web view funnel and native flows), and complex checkout flows.\n Rapid Iteration & Experimentation (CRO): Implement a high-velocity experimentation framework to allow for rapid A/B testing of funnel logic, pricing variations, questionnaire changes, designs, and animations.\nAdvanced Analytics & Data Flow: Implement and maintain robust, server-side event tracking, ensuring high data quality and integrity for critical marketing systems.\n Marketing Integrations: Manage deep integrations with our marketing partners (e.g., AppsFlyer), advertising platforms (e.g., Facebook Conversions API, Google Ads), and business intelligence tools.\n Data Warehousing: Ensure all necessary event data is accurately captured and routed to our internal data warehouse (BigQuery) for reporting and business analysis.\nProduct Collaboration: Work directly with Marketing and Product teams to translate growth strategies into scalable, performant, and reliable code.\n User Communication & Notifications: Own the technical implementation, delivery, and integration of user notification systems (push, in-app messaging, and email hooks) to support re-engagement and lifecycle marketing efforts.\nOur Stack\nFrontend: React, React Native\nBackend: Node.js, MongoDB\n Infrastructure: AWS (ECS, S3, EC2)\nTools: GitHub Copilot, AI-assisted workflows, various marketing/analytics platforms.\nKey Requirements\n4-5+ years of fullstack development experience, ideally in a fast-paced B2C environment.\nStrong expertise in React and React Native with a keen eye for front-end performance optimization and UI/UX designed for conversion.\nSolid backend skills with Node.js and MongoDB for supporting APIs that power dynamic funnels and handle server-side tracking.\n Mandatory: Deep, demonstrable experience with marketing event tracking, pixels, and server-side integrations (e.g., Facebook CAPI, Google Analytics, GTM).\nComfort working with RESTful APIs and managing end-to-end features.\nExperience deploying to AWS (ECS, S3, EC2).\nStrong product intuition and a proven ownership mindset for high-value features.\nBonus Skills\nPrior experience building and maintaining A/B testing/experimentation frameworks (e.g., Optimizely, LaunchDarkly, in-house tools).\nCI/CD, A/B testing frameworks\nExperience querying or managing data flow into BigQuery (BQ).\nFamiliarity with Angular or other legacy frontend frameworks.\nPython or scripting for backend tools and data processing.\n UI/UX sensibility and attention to detail\nWhy Join Singit\nDirect Impact: You will be responsible for the code that directly drives company revenue and growth metrics.\n High Autonomy: Own the entire technical growth stack and help shape our acquisition strategy.\nWork in a creative, fast-moving team dedicated to making language learning fun.\nFlexible work culture focused on
