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 - 1,000 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.

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.
