What We’re Looking For
We’re on the hunt for a Senior Frontend Engineer who’s ready to take ownership, lead with innovation, and build exceptional systems in the Monetization team – a core part of our Product Growth structure. If you’re passionate about data-driven user journeys, experimentation, and highly optimized purchasing flows – this is something for you.
Our Monetization team maximizes user trust by creating seamless, transparent pricing experiences. We’re a data-driven engine, constantly running experiments, refining strategies, and unlocking sustainable revenue growth. You’ll work alongside experienced team members to evolve our monetization models and build products that matter – both for our users and our business.

Key responsibilities:
Collaborate across disciplines: Work closely with cross-functional teams including Frontend/Backend Engineers, QA, Product Analysts, and Product Managers to design, develop, and deliver innovative solutions that directly influence user experience and revenue. You won’t just ship code — you’ll shape how millions interact with our products.&nbsp;
Engineer with purpose: Translate business requirements into performant, maintainable code that shapes user trust and monetization experience.&nbsp;
Own your systems: Take responsibility for system performance, scalability, and data integrity. Spot issues before they happen and suggest smart fixes. Participate in monitoring (Sentry, Datadog).
Drive product and system evolution: Take initiative in shaping the future of our user identity and privacy systems. Audit what exists, identify areas for improvement, and lead the transformation of existing flows into modern, user-first solutions that unlock real value for both the company and our users.
Elevate the Standard: Be a champion of engineering excellence. Drive clean code practices, lead code reviews, mentor peers, and contribute to a culture of innovation. Share knowledge and bring strategic thinking into technical discussions.
Build with Best-in-Class Tech: Craft modern solutions using React 18+, React-Query, Styled Components, TypeScript 5+, and Vite. Help shape how we architect, deploy, and scale services used by a global user base.&nbsp;
Required skills:

Senior-level experience building and maintaining frontend applications in a product-first environment

Mastery of JavaScript (ES6+) and TypeScript, with an eye for performance and maintainability

Advanced knowledge of React and its ecosystem — you’re comfortable with Redux Saga, Core Web Vitals, and beyond

A deep understanding of how the web works, including RESTful API integration, web security, and responsive UX patterns

Solid grasp of software design principles — you live by SOLID and know how to apply design patterns pragmatically

Experience implementing testing strategies

Strong communication skills and fluent English (C1) — you’re confident leading discussions and documenting decisions

A passion for crafting delightful user experiences, and a mindset of continuous growth and learning

Nice to have:

Experience working with experimentation platforms and running A/B or multivariate tests

Experience with Material UI and its design philosophy

Familiarity with Next.js, SSR, and performance optimization

The confidence to set up or optimize bundler configs (Webpack/Vite) from scratch
