Onboarding Engineer

Mangomint is a fast-growing SaaS company on a mission to make every salon and spa more profitable. We are already the highest-rated salon and spa software in the US and Canada with thousands of customers and seek to become the #1 market leader in the coming years.

We’re a fully remote, fun, and ambitious team and get together every few months in person. As we grow, we’re looking to attract high-potential individuals who want to be part of a winning team. If that’s you, come join us!

As a Onboarding Engineer at Mangomint, you’ll play a critical role in shaping how new users experience our product from day one. You’ll work across both customer-facing onboarding flows and internal tools that help our team onboard new clients more effectively. This is a frontend-heavy role where you’ll partner closely with Product, Design, Marketing, and Customer Success to design intuitive, elegant, and impactful onboarding experiences that improve activation, time-to-value, and retention.

You’ll also contribute to our broader frontend codebase, collaborating with other engineers to maintain high standards of quality and performance. Whether you're mid-level and eager to grow or bring deeper experience to the table, this role offers a unique opportunity to own high-impact surface areas and build features that define first impressions of Mangomint.

In the Onboarding Engineer role at Mangomint you will:

• Design and implement user onboarding experiences — from first login through setup, education, and activation

• Collaborate with Design and Product to create intuitive flows that help new users find value quickly and confidently

• Work with Customer Success and Marketing to build internal tooling and scalable solutions for client onboarding

• Develop polished UI using React, TypeScript, and modern CSS/Sass
