Frontend Engineering Intern - Summer 2025
San Francisco, CA, New York, NY, Portland, OR, or Remote within Canada or United States
Itâs 1813 and Humphrey Davy is dazzling London with scientific demonstrations and lectures. Soon enters the young bookbinder, Michael Faraday, dissatisfied with his own prospects and enamored by the mysteries of electricity. Faraday gets a break and gains an apprenticeship with Davy, and shortly thereafter (partially) blows himself and Davy up in a nitrogen trichloride explosion.
We think Davyâs sacrifice was worth it, though, since Faraday went on to do experimental work in the field of electromagnetism that is foundational to innumerable modern technologies. While we canât promise youâll become the next Faraday, we can promise you wonât be asked to deal with explosives on the job.
Instead, youâll be receiving mentorship from experienced engineers, writing TypeScript and/or Haskell code, and contributing to a product that serves over 100,000 businesses. Check out demo.mercury.com to see our product for yourself.
As an Engineering Intern, youâll join a team that aligns with your goals and interests. During the interview process, youâll have the opportunity to talk through the various team openings.

- Be interested in continually honing their craft.
- Have curiosity and be willing to share their perspective.

- Communicate well, and be able to write clear explanations of their reasoning on technical decisions.
Frontend Engineering Interns should have experience with the TypeScript programming language, and experience with React is a plus. In this role you can expect to:
- 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 TypeScriptâs advanced static typing features to prevent them.
- Work in an established codebase that still has room for growth. Across 650K lines of TypeScript, weâve built abstractions and components that will give you leverage to build great features during your months at Mercury. But thereâs still a lot more to build, be it optimizing the scrolling performance of a combobox, or building whole pages to âŚ
