Senior Front-End Engineer (Lead)

Senior level • Full-time • On-site • Cluj-Napoca


Our partner was created in response to the complex issues surrounding risk management. The designers recognized then that, to proactively measure and manage risk, it was necessary to determine the total exposure of a financial institution across all of its global activities.

Since then, our partner has helped transform the way Banks, Hedge Funds, Brokers, CCPs, and Stock Exchanges, measure their risk and manage their capital.

They are looking for an experienced front-end developer who is proficient with React.js to join their new development centre. The primary focus of the selected candidate would be on developing user interface components, implementing and executing them following well-known React.js workflows. Also, ensuring that these components and the overall application (developed from scratch) are robust and easy to manage. A commitment to collaborative problem solving, sophisticated design, and quality products is important.

This is a fantastic opportunity to join a fast-growing FinTech company with a world-renowned team with risk management expertise, in an established, successful, and rapidly growing company in a global development role. You will work in a fast-paced and dynamic environment as part of our global close-knit product development team at Razor.
