About Mangomint

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!

About the Role

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

Own the frontend implementation of A/B tests, feature flags, and experiments that improve onboarding KPIs

Contribute to our frontend architecture, component library, and UX consistency

Help improve engineering standards, tooling, and practices for frontend development

Technologies You Will Work With

Frontend: TypeScript, React, Sass/CSS

Backend/REST API: Kotlin/JVM, PostgreSQL, AWS (RDS, SQS, Lambda, EC2/EB)

Tooling & Testing: Jest, Cypress, Feature flagging libraries (e.g., LaunchDarkly, Split.io — experience with any is a plus)

While experience with our exact stack is helpful, we care more about your engineering skills and your ability to quickly learn and adapt to new technologies.

What We’re Looking For

• Experience building high-quality user interfaces with modern frontend frameworks (ideally React)

  Strong product sense and an interest in how UX impacts user behavior and product adoption

  Experience collaborating with cross-functional teams — including Product, Design, and Customer Success

  A detail-oriented mindset with a passion for smooth, accessible, and responsive user experiences

  Ability to balance speed and quality — shipping thoughtfully, but often

  Experience working on onboarding or lifecycle features is a plus, but not required
