The Role

As our Front-End Engineer Intern, you will be the champion of our migration to Tailwind CSS. Your primary mission will be to systematically audit our ReasonML components, abstracting inline styles and traditional CSS into a clean, reusable, and utility-first Tailwind CSS framework. You will work closely with our senior engineers and designers to ensure the final product is not only visually identical but also more performant and easier to maintain.

We are passionate about building elegant and powerful web applications using cutting-edge technology. Our front-end is built on the robust, type-safe ReasonML platform, which allows us to write scalable and maintainable code. We are looking for a motivated and detail-oriented intern to join our team and help us undertake a crucial project: modernizing our entire styling architecture with Tailwind CSS.

This is a fantastic opportunity to gain hands-on experience with a unique, functional programming stack and to make a significant, visible impact on our product's user interface and codebase.

Responsibilities

Analyze existing ReasonML components and their associated CSS to plan the migration strategy.
Methodically refactor components to replace legacy CSS with Tailwind CSS utility classes.
Collaborate with our design team to ensure pixel-perfect consistency with our design system.
Help build a robust and well-documented component library based on the new Tailwind implementation.
Learn and apply best practices for building scalable front-end applications with ReasonML and functional programming principles.
Participate in code reviews to learn from the team and improve your skills.

Required Skills

A solid foundation in HTML and a strong understanding of CSS, including concepts like the box model, flexbox, and grid.
Familiarity with modern JavaScript (ES6+) and its core concepts.
A keen eye for detail and a passion for creating clean, organized, and beautiful user interfaces.
An enthusiastic and proactive learner who is excited to dive into new technologies.
Excellent problem-solving skills and the ability to work both independently and as part of a collaborative team.

Preferred Skills

Prior experience with Tailwind CSS.
Any exposure to or interest in ReasonML, ReScript, or OCaml.
Experience with statically typed languages like TypeScript, as it highlights an interest in the type safety we value with ReasonML.
Familiarity with version control systems like Git.

What You’ll Gain

A unique opportunity to work with a forward-thinking, functional programming tech stack.
Dedicated mentorship from experienced senior engineers who are invested in your growth.
A high-impact project that you can own and showcase in your portfolio.
A collaborative, friendly, and inclusive work environment.

We are a hybrid workplace that recognizes the importance of flexibility while valuing in-person collaboration and relationship building. As a result, Saucers located near an office location must be able and willing to come into the office.
