Job Description

We’re seeking a highly motivated intern to join our engineering team for Summer 2026. You’ll be working in-person in our NYC office, with a pay-rate of $2,500/week, alongside two other interns in different pods. You'll be a member of our Interactives pod, building games that teach. Our games blend thoughtful mechanics, intuitive level design, and deep pedagogical insights. Each game is driven by APIs designed for experts and LLMs where every possible configuration is guaranteed to be a correct, solvable, and meaningful puzzle. It's a tricky technical problem with a big payoff for our learners. This will be real work, on real priorities, affecting real users — not “intern projects”. You need to be able (and excited) to hit the ground sprinting, which likely means that you’ve shipped substantial code into a production environment before (either at another startup or for a scaled side-project). By the end of the internship, if all goes well, you’ll have made a material impact on our customers and the future of learning. You’ll have meaningfully up-leveled because of who you get to work with, and hopefully we’ll be mutually eager for you to start full-time ASAP.

Job Responsibility

  • Building games that teach
  • Blend thoughtful mechanics, intuitive level design, and deep pedagogical insights
  • Work on games driven by APIs designed for experts and LLMs

Requirements

  • Want to work at Brilliant full-time, and are graduating in 2027 (or sooner, or are planning to drop out)
  • Have shipped substantial code to production at a company serving real customers with an emphasis on polished frontend interactions and designs
  • Have prior internship experience at a startup, and/or created a side-project or small business that required dedication over a span of months/years
  • Consistently use AI when coding, while having a deep, nuanced understanding of limitations/pitfalls + what great code looks like
  • Are already excellent at your craft, and want to be surrounded by people who will push you even further
  • Specifically want to join a small company where every person works very hard and has outsized ownership
  • Are driven by building useful things that impact real people (versus creating hype without utility)
  • Are an excellent writer + reader (because we have a writing-heavy culture)
