Role

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

Desirable

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

We usually respond within two weeks

Our take

Learning a new language is no mean feat, but the era of learning apps has certainly made it simpler and more accessible than ever before. Praktika hopes to improve the experience even more. It employs GenAI avatars to make the language learning experience feel more natural.

Through the Praktika app, users can access 1-to-1 tutorship powered by these avatars, which have individualized backgrounds and a range of accents. The company's aim is to combine the precision of a tutor with the fun of an app, supplying lessons, practice and feedback through a colourful UI.

Aiming to compete with tutorship rather than other learning apps, Praktika stands out as a cost-effective way for individuals to access 1-to-1 learning on their own schedule. This approach resulted in its 2024 fundraising of $35.5M, which is being used to heighten the app experience, improve avatar accuracy and add new languages.
