GlossGenius is building an ecosystem enabling entrepreneurs to succeed. We empower small business owners to focus on being creators, not admins, by offering a range of business management tools, including booking and scheduling, marketing, analytics, payment processing, and much more.

Over 100,000 small business owners have chosen to rely on GlossGenius every day to run their entire set of business operations. Joining its powerful, intuitive platform with its vibrant, distinguished brand, GlossGenius is the ideal combination of a fintech, SMB software, and consumer company all in one.

GlossGenius has been empowering independent entrepreneurs in the beauty and wellness space to pursue their dreams and successfully grow their businesses. As we continue to scale, we're strengthening our App Platform team. This team is foundational to everything we build — from enabling developer velocity to ensuring web reliability and performance at scale.

As a Staff Frontend Engineer on the App Platform team, you will play a leading technical role in shaping our web platform at GlossGenius. We are not owners of individual features but enablers of scalable, consistent, and high-quality engineering. Our scope includes shared UI frameworks, component libraries, tooling, and release infrastructure — we are building the platform that product teams rely on to deliver value. We also believe AI is a force multiplier for great engineering, and we're actively embedding AI-powered tooling and practices into how we build and ship software. Our mission is to provide the foundation that helps every team move faster, build better, and scale with confidence.
