Senior Frontend Engineer

Hello, We are called People More because we treat our employees with respect, but also because the projects we work on are for people and should be easy and pleasant to use. We are technological, but we look at the bigger picture :) The company is made up of people with a huge client base in the country and abroad, for whom we build projects from scratch (UX, UI, frontend, backend, mobile) or in part. We work directly for our clients and also support our partners in their own solutions. This ensures a wide range of projects and the ability to change! We work with clients all over the world. For the project that we are working on with our partner, we are looking for Senior Frontend Engineer.

• Developing and maintaining frontend integrations with backend systems through REST and GraphQL APIs.
• Implementing interactive, real-time application features using Server-Sent Events (SSE) and comparable technologies.
• Building secure, reliable, and user-friendly interfaces for payment-related processes in accordance with relevant industry standards and security practices.
• Enhancing frontend development tools, improving developer experience, and contributing to efficient, modern engineering workflows.

Requirements that must be met

• Strong hands-on experience with TypeScript and at least one of the following frameworks or libraries: React, Vue, or Angular.

• Experience developing, maintaining, and executing automated end-to-end tests using Playwright or similar testing frameworks.
• Solid understanding of frontend performance optimisation, including Core Web Vitals, application profiling, and bundle analysis.
• Proven experience integrating frontend applications with REST and GraphQL APIs.
• Familiarity with authentication and authorisation mechanisms, including OAuth2, OIDC, and JWT, as well as feature flags and progressive delivery practices.
• Regular use of AI-assisted development tools, such as GitHub Copilot, ChatGPT, Claude, or equivalent solutions, to improve coding efficiency and software quality.

Nice to have

• Previous experience developing products or applications in the payments, FinTech, or e-commerce sectors.

• Knowledge of web accessibility guidelines, particularly WCAG.
• Additional backend development experience with Node.js, Java, Python, or C#.
• Experience designing or developing embeddable frontend widgets or Software Development Kits (SDKs).
