Senior Frontend Developer (React)

Senior • Remote

100 - 130 USD

Warsaw, Poland

We are hiring a Senior Frontend Engineer to join a product-focused team working on modern web applications for our client.

In this role, you’ll take the lead in building user-facing features that are reliable, scalable, and easy to maintain. You’ll work at the intersection of engineering, product, and design — turning ideas into real, high-quality solutions used by end users.

This is a position for someone who is comfortable making decisions, taking responsibility for their work, and actively shaping the frontend layer of the product.

Your day-to-day

  • Build and evolve frontend features with a focus on scalability and long-term maintainability

  • Turn product concepts and design mockups into functional, high-quality interfaces

  • Work closely with product and design stakeholders to refine solutions and improve user experience

  • Take care of application performance, accessibility, and overall code health

  • Influence technical direction within the frontend domain

  • Spot inefficiencies and improve existing solutions and codebase structure

  • Own your work end-to-end — from idea to production.

What we’re looking for

  • Solid commercial experience in frontend development with React

  • Confidence in delivering complex features without close supervision

  • Experience collaborating with non-engineering stakeholders (e.g. product, design)

  • Strong focus on code quality, readability, and long-term maintainability

  • Ownership mindset — you don’t just implement tasks, you drive solutions.

Nice to have

  • Experience working on complex or large-scale web platforms

  • Exposure to shared frontend ecosystems or multi-team environments

  • Familiarity with component-driven development and design systems

  • Interest in growing your skills in TypeScript and modern frontend testing practices
