Senior Full Stack Web Developer

Who you are

• We're looking for outstanding engineers who thrive in a challenging environment, bring a growth mindset, and operate with a high degree of agency, devotion, and autonomy
• Product-first mindset: you think in user problems and business outcomes, not just code
• Extensive experience with TypeScript, React (hooks, context, state management), and Node.js
• Proficiency across modern full-stack tooling: Next.js (or equivalent), CSS-in-JS or Tailwind
• Hands-on experience integrating auth providers (Firebase, Auth0), payment systems (Stripe, RevenueCat, PayPal), feature-flag platforms (LaunchDarkly, Flagsmith), and analytics tools (Amplitude, PostHog)
• Strong UI/UX sensibility; you care about animation, micro-interactions, and conversion details
• Comfortable working with RESTful APIs and collaborating closely with backend teams
• Data-driven approach with proven experience in A/B testing, funnel optimization, and analytics
• Ability to thrive in an async, distributed, written-first culture
• A portfolio of high-quality web projects and successful conversion experiments
• Prior experience at an early-stage or high-growth consumer product company

What the job involves

• We're hiring a Senior Full-Stack Engineer to own and evolve every web-facing surface at Praktika; onboarding flows, landing pages, customer portals, our web app, and internal tools. This is a full-cycle product engineering role: you'll shape product direction, design and run experiments, ship features end-to-end, and measure their impact on conversion, retention, and learner experience
• You'll partner closely with Product, Marketing, and Growth, and your work will directly influence how tens of millions of learners discover and engage with Praktika
• Own the entire web stack: marketing site, onboarding funnels, customer portals, web app, and internal tools
• Lead architecture, development, experimentation, and operations across all web applications
• Drive product decisions: contribute to the vision, design and run A/B tests, analyze results, and iterate quickly
• Build adaptive, animated, mobile-first experiences that convert and delight users
• Integrate with backend services (via Swagger docs), authentication providers (Google/Apple SSO), and payment gateways (Stripe, PayPal, RevenueCat)
• Set up and optimize analytics, tracking, and conversion funnels in collaboration with Growth and Marketing
• Ship production-ready code end-to-end; from idea through deployment to monitoring
