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 Senior 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. In this role, you’ll partner closely with our Sales and Onboarding teams to design intuitive, elegant, and impactful onboarding experiences that improve activation, time-to-value, and retention.

This role offers a unique opportunity to own high-impact surface areas and build features that define first impressions of Mangomint.

In the Senior Onboarding Engineer role at Mangomint you will:

Work with Sales and Onboarding to build internal tooling and scalable solutions for users first interaction with our platform

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

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

Technologies You Will Work With

Frontend: JavaScript, Node, Playwright, Ramda, React

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

Tooling & Testing: Docker, Jest, Pulumi

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
5+ years of relevant experience

Strong understanding of the Document Object Model (DOM) tree

Proficiency in promise-based JavaScript for handling asynchronous operations

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

What You'll Love About Us
Competitive compensation

Employee stock options

Comprehensive health coverage (health, dental, vision, life & disability)

Generous monthly wellness budget (gym, massage, etc.)

Premium Calm app & One Medical membership

Flexible, unlimited PTO

401k, HSA and FSA plans available (no current match)

Mangomint is an equal opportunity employer. We do not discriminate against any employee or job applicant on the basis of race, color, religion, sex (including pregnancy, sexual orientation, and gender identity), national origin, age, disability and genetic information (including family medical history
