Senior/Lead FrontEnd Engineer

For our client in Krakow, we are looking for a Senior/Lead FrontEnd Engineer.

Location: Krakow/Poland

Work model: fully remote

Type of collaboration: B2B

Project duration: 12 months 

About client

Our client is a well-established UK-based technology group providing innovative software and payment solutions across multiple industries. The company focuses on delivering secure, cloud-based platforms that help organizations streamline operations, enhance customer engagement, and achieve digital transformation. With a collaborative culture and a commitment to professional development, the company offers its employees the opportunity to work with modern technologies in an international environment.

About role

We’re building the foundation for our next-generation embeddable component platform — reusable, framework-agnostic UI components that power partner and merchant dashboards across our ecosystem.

As a Senior / Lead Front-End Engineer, you’ll shape the architecture, prototype new ideas, and make key technical decisions that define how our products scale. Expect a mix of hands-on engineering, experimentation, and technical strategy — perfect for someone who thrives on turning vision into clean, elegant, high-performing UI systems.

You’ll be great at this if you have

• 6+ years of experience in modern front-end engineering (TypeScript, JS, React/Angular/Svelte).
• A passion for component libraries, SDKs, or design systems.
• Strong grasp of Web Components, modular architecture, and CI/CD pipelines.
• A builder’s mindset: experiment, learn fast, iterate faster.

Why join us? We’re competing on speed, focus, and smart technology, not headcount. You’ll have the autonomy to shape a platform that scales across teams and products.
