Whether we are designing autonomous multi-agent AI systems, building decentralized financial infrastructure, or architecting high-frequency iGaming platforms, our standard is excellence.

We move fast, but we build for the long term. If you are looking to work alongside a team that values deep technical expertise, thoughtful system design, and product ownership, Block Labs is where you belong.

About The Role

As a Senior Frontend Engineer, you will help build high-performance, modular and visually engaging interfaces across a range of cutting-edge platforms. You will work within a cross-functional team of engineers, product managers and designers to deliver seamless user experiences across web application. This is a hands-on role with significant influence over architectural choices, component design and frontend tooling.

Key Responsibilities:

· Design and implement user-facing features with strong attention to performance, responsiveness and UX

· Build, maintain and refactor modular React-based interfaces for scalability and reusability

· Advocate for clean, testable and maintainable code through peer reviews and documentation

· Optimize applications for speed, cross-browser compatibility and accessibility

· Work within a modern CI/CD pipeline to ship features efficiently and safely

· Contribute to shared design systems or internal tooling as needed

About You:

· You have over 5 years of experience in frontend engineering with a focus on creating high-quality, scalable web applications

· Strong expertise in React (or comparable frameworks) and modern JavaScript/TypeScript

· Previous experience with micro frontend architectures is a plus

· Experience with build tools (like Bun, Vite, Webpack) and testing frameworks (such as Cypress or Selenium) is essential

· You have experience in DevOps practices and containerization technologies in cloud environments

· You are passionate about software quality and creating exceptional user experiences

· You have a strong command of both verbal and written English

· Background in fintech, DeFi, or iGaming is a bonus

What kind of culture can I expect?
Mature, mission-driven, and low-ego. We value clarity over noise, outcomes over theatrics, and pace without chaos. If you’re one of the smartest minds in your craft and want to build with other experts, you’ll feel at home here.

The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
