Frontend Engineering Intern

Summary

Join Mercury's Engineering Internship program and receive mentorship from experienced engineers while contributing to a product used by over 100,000 businesses. As an intern, you will write TypeScript and/or Haskell code, work on a beautiful app, push the limits of TypeScript, and exercise ownership over the product. The internship is a paid, full-time, remote summer position lasting 12-16 weeks between September and December. It's open to individuals enrolled in an academic program. The hourly rate is $55 for US-based candidates and CAD 55 for Canadian candidates. Applications close on May 30th, 2025.

Requirements

• Be interested in continually honing their craft
• Have curiosity and be willing to share their perspective
• Appreciate quality in their work and that of others
• Communicate well, and be able to write clear explanations of their reasoning on technical decisions
• Have experience with the TypeScript programming language
• Our internship program is intended for individuals enrolled in an academic program (undergraduate, graduate, etc.)

Responsibilities

• Work on a beautiful app: Since many of our customers are startups, they appreciate a well-implemented design. We have high standards for our UI, and we think it shows on our website. We encourage you to sign up and check out our onboarding experience, or read our blog post about our date picker
• Push the limits of TypeScript: As a financial technology company, preventing errors is a top priority for us, and we take advantage of TypeScript’s advanced static typing features to prevent them
• Work in an established codebase that still has room for growth. Across 650K lines of TypeScript, we’ve built abstractions and components that will give you leverage to build great features during your months at Mercury. But there’s still a lot more to build, be it optimizing the scrolling performance of a combobox, or building whole pages to deliver a feature to customers
• Exercise ownership over the product: Our engineers work closely with our designers and contribute their own ideas to make the product better

Preferred Qualifications

• Experience with React
• Individuals interested but not enrolled in an academic program at this time are encouraged to apply to any of our full-time openings

Benefits

• This is a paid full-time remote summer internship for 12-16 weeks between September - December
