• Participate in technical design discussions and code reviews.

• Learn how high-performing engineering teams actually build software.

What We're Looking For

• Build things for fun.

• Ask great questions.

• Enjoy solving problems that don't have obvious answers.

• Like moving quickly.

• Aren't afraid to admit when you don't know something.

• Care more about learning than looking smart.

• Open-source contributions.

• Hackathons.

• Research projects.

• Startup experience.
