About Us
At Praktika, we are building the best AI tutors to teach millions of students new languages. Since we launched our mobile apps in 2023, we have gained over 2 million MAU, become one of the world's top-4 learning apps, and are aiming to lead the AI revolution in education and become the solution of choice for contemporary language learners. We've secured our $30 million Series A funding and are scaling the team to run faster!
About The Role
We are seeking a Senior Full-stack Engineer for our web team to own and evolve all web-facing assets at Praktika — from onboarding flows and landing pages to internal tools and web-based product features. This is a full-cycle product engineering role: you'll contribute to the product vision, design experiments, ship features, and measure impact. You'll work closely with Product, Marketing, and Growth teams to drive conversion, retention, and user experience across all web touchpoints.
What You'll Do At Praktika
- Own the entire web stack — main website, onboarding funnels, customer portals, web app, and internal tools.
- Lead architecture, development, experiments and operations for all web applications.
- Drive product decisions: dive into the product vision, run A/B tests, analyze results, and iterate fast.
- Build adaptive, animated, mobile-first experiences that convert and delight users.
- Integrate with backend services (using 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 to deployment to monitoring.
What We Are Looking For From You
- Product mindset first: you think in user problems and business outcomes, not just code.
- Extensive experience with Typescript, React (hooks, context, state management) and Node.js.
- Proficiency with modern full-stack tooling: TypeScript, Next.js or similar, 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/marketing tools (Amplitude, Posthog).
- Strong sense of UI/UX — you care about animations, micro-interactions, and conversion details.
- Comfortable working with RESTful APIs and collaborating with backend teams.
- Data‑driven approach: experience with A/B testing, funnel optimization, and analytics tools.
- Bonus: Portfolio showcasing high-quality web projects and successful conversion experiments.
Why Should You Join Praktika
- Equity that grows with your impact: Equity growth via stock options.
- 26 days of holidays plus bank holidays (34 days per year).
- Yearly off‑sites: Last year was Istanbul.
- Health and wellness benefits via Safetywing.
- Access to an AI toolkit, including Claude, Cursor, Codex, and other productivity tools.
- Annual educational budget of up to $1,000.
