Why We’re Hiring For This Role

At Float, we’re dedicated to delivering a fast, seamless experience for our customers. As our average customer size continues to grow, so does the complexity of their needs. This role is critical to ensuring that Float remains a best-in-class resource management tool, providing a smooth and intuitive experience for every user.

The Senior Front End Performance Engineer role is essential in helping us tackle one of our biggest challenges: optimizing the performance of our web application for larger teams, particularly those within our target audience of 11-1000 members.

Our customers rely on the Float schedule as their “home view,” and its performance directly impacts how quickly and easily they can plan, adjust, and succeed. One of your main responsibilities will be optimizing the performance of this feature.

Beyond optimizing our current product, this role is also about shaping the future. You’ll ensure new features are scalable, performance regressions are avoided, and our product evolves to meet the demands of a growing customer base. Your specialized expertise in front-end performance will directly support Float’s growth goals, both in expanding our customer numbers and increasing the team sizes we serve.

You will also help foster a “culture of performance” in the larger Interfaces team by advocating for best practices and tooling, reviewing new code, implementing performance monitoring, and by sharing knowledge with other team members.

This is a unique opportunity to not only make an impact within our team but to influence the experience of thousands of professional services organizations who rely on Float every day.

This role reports to Haakon, our Team Lead (Interfaces). You can meet them below, where they explain the important role you will play within our Interfaces team. Watch this video.

•  Front-end performance: You will be contributing to a best-in-class front-end performance of our product
•  Tooling and Processes: Defining performance-oriented tooling and implementing best-practices for the larger Interfaces Team, as well as sharing your knowledge.
