Campfire is building the next generation of games and consumer apps powered by AI. Our first product is a cozy lifesim game with AI NPCs at the heart of the gameplay experience for PC and mobile platforms. We are a small and laser-focused team doing something new and innovative.

We are a team of experienced product builders from Peloton, Microsoft, and Replika who've built products and games for millions of people. We're backed by some of the world's top tech and gaming investors including YCombinator and backers of Coinbase, Instacart, and many more.

We're looking for a founding engineer to join our team! You'll be employee #5 and the heart of the founding technical team. You will help develop critical features for Campfire’s foundations and help it scale as we launch. It is the perfect time to join this rocketship and make a huge impact.

You will work on building out our mobile Consumer Products and other showcase products for Sprites, like Cozy Friends and the upcoming mobile app companion Aurora (wt).

From UIs, authentication, applied AI, payments, backend services, live operations, infrastructure, and even more! You will have major influence on the company’s foundational stack.

You will:

1. Help define and create our core technology stack architecture for the consumer apps along with the technical founder.
2. Build features across the board for our web and mobile consumer apps such as Cozy Friends and Aurora (wt).
3. Develop server apps, cloud functions, cron jobs, etc., required to support live and networked user features such as push notifications.
4. Contribute to overall developer velocity by smartly investing in our tooling and library code.
5. Rapidly prototype ideas for growth features.

You must have:

1. Demonstrated history of being a hands-on builder of snappy consumer or prosumer products—work or hobby projects.
2. 3+ years of experience working as a Software Engineer in web or mobile apps, having worked across the entire stack—from UIs to infrastructure.

4. Deep experience with modern Swift, React Native, Flutter, Unity with at least some familiarity with the others.
5. Some familiarity with native iOS app development and Swift—or at least eager to learn the basics fast.
6. Familiarity with modern cloud platforms such as Google Cloud or AWS.
7. Creative eye and a user-first mentality.
8. Passion for cutting edge of applied AI for consumers and gaming—ideally both!

Bonus Points for:

2. Experience with multiplatform mobile product codebases like Unity, React Native, Flutter, etc.
3. Desire to make a huge impact at an early stage venture-backed gaming startup with huge upside.
