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.
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.
- Proficiency across modern full-stack tooling: Next.js (or equivalent), CSS-in-JS or Tailwind.
- Strong UI/UX sensibility: you care about animation, micro-interactions, and conversion details.
- Data-driven approach: with proven experience in A/B testing, funnel optimization, and analytics.
- Hands-on experience: integrating auth providers (Firebase, Auth0), payment systems (Stripe, RevenueCat, PayPal), feature-flag platforms (LaunchDarkly, Flagsmith), and analytics tools (Amplitude, PostHog).
- Comfortable working with RESTful APIs and collaborating closely with backend teams.
- Extensive experience with TypeScript, React (hooks, context, state management), and Node.js.
- Ability to thrive in an async, distributed, written-first culture.
- Prior experience at an early-stage or high-growth consumer product company.
- A portfolio of high-quality web projects and successful conversion experiments.
