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

🏢 Summary: Frontend Developer role focused on building scalable, high-quality e-commerce web applications using React and TypeScript. The position involves developing performant UI components, ensuring excellent UX, and contributing to architecture, testing, and CI/CD processes. Collaboration with product, UX, and mobile teams (Flutter) is key to delivering consistent cross-platform experiences. 🗂️ Requirements: Minimum 3 years of frontend development experience, Strong proficiency in React and TypeScript, Experience with modern HTML and CSS, Experience integrating REST APIs and GraphQL, Knowledge of frontend testing (unit, integration, E2E), Experience with CI/CD pipelines and Docker, Understanding of Clean Code and Test-Driven Development, Ability to optimize web performance and accessibility, Familiarity with modern frontend architectures, Experience working in agile development environments 📃 Skills: React, TypeScript, HTML, CSS, SASS, LESS, Tailwind, Flutter, Dart, GraphQL, REST, Docker, CICD, Jest, Cypress, Playwright, MicroFrontends, DDD, TDD, CleanCode, CoreWebVitals, a11y, Monitoring, ErrorTracking 🏢 Description: Shape the future of E-Commerce with us! Are you ready to develop innovative frontend solutions for online shops with your team, increasing our brand awareness and strengthening customer loyalty? Do you enjoy getting hands-on with modern web technologies and developing high-quality software? Then you are exactly right for our Engineering Team! As a Frontend Developer , you are an integral part of a cross-functional team and report to your Team Lead Engineering. You work closely with your teammates, product management, as well as UX and other specialist departments to realize innovative and customer-oriented solutions. Your Mission You develop high-quality and scalable frontend architectures with passion and technical expertise. Through your commitment, you contribute significantly to implementing technical innovations and continuously improving the User Experience (UX). Your focus is clearly on the Web Frontend with React and TypeScript . At the same time, you are curious about neighboring technologies: Your know-how (or your interest) in Flutter helps us bridge the gap between Web and Mobile App and leverage synergies. Your tasks in detail Technical Responsibility & Development: Analyze, design, and implement new features for our online shops – from the first idea to going live. Develop performant, reusable components in React and TypeScript and ensure a pixel-perfect implementation of sophisticated UI/UX designs. Use your understanding of mobile development (Flutter) to promote professional exchange with the App Team and ensure consistent user journeys across Web and App. Conduct code reviews and promote the application of Clean Code and Test-Driven Development in the frontend. Recognize technical debt and derive targeted measures for its reduction. Quality Assurance & Best Practices: Ensure high development standards, test processes (Unit, Integration, E2E tests), and technical documentation. Optimize the performance of our web applications (Core Web Vitals) and ensure accessibility (a11y). Identify and actively support the maintenance and optimization of frontend build pipelines and test environments. Collaboration & Planning: Work closely with product management and your team to specify requirements, realistically estimate development efforts, and implement solutions effectively. Actively participate in decisions regarding technological direction and bring in suggestions for selecting suitable tools and frameworks in the React ecosystem. Operations & Infrastructure: Support the operation and monitoring of the applications you have developed (Monitoring, Error Tracking). Actively help to continuously improve CI/CD processes for the frontend. What you bring At least 3 years of practical experience in frontend development, ideally in an e-commerce environment. Excellent knowledge of TypeScript and React as well as modern HTML and CSS (SASS/LESS, CSS-in-JS, or Tailwind). An advantage: Knowledge of Flutter and Dart. You understand the concepts of mobile development and can exchange ideas on an equal footing with our mobile developers or even support them punctually. Familiarity with architectural concepts such as Micro-Frontends , Domain Driven Design (DDD), or Self-Contained Systems is an advantage. Knowledge of handling REST APIs as well as GraphQL. Broad experience with CI/CD tools, container technologies (Docker), and an affinity for agile working methods. A high degree of quality awareness for Clean Code, tests (e.g., Jest, Cypress, Playwright), and technical documentation. Strong communication skills, openness to constructive feedback, and a cooperative way of working. Active exchange within the developer community as well as the willingness to regularly bring new knowledge and innovative ideas to the team. We’re probably not a great match if you... Prefer frameworks like SAFe or projects that kick off with a rigid set of formal specifications ( Lastenheft ). Have worked primarily in highly regulated industries without experience in fast-paced, product-led environments and distributed systems. Feel more comfortable in role models where infrastructure, backend, frontend, testing, and product thinking are strictly siloed. Expect requirements to be handed to you fully "ready to go," instead of refining them alongside Product Management and striving to truly understand the customer. View professional development mainly as the employer's responsibility , rather than learning out of your own curiosity—whether that’s on the job, at an evening event, or simply by picking up a book. Are more frustrated than motivated by imperfect systems —spoiler alert: we aren't "there" yet. Strictly separate work from having a good time.
