Founding Engineer

About the role

About Brainbase

Brainbase is to AI Employees what Retool is to internal tools.

We envision a future where every company has an AI workforce working alongside their human team. Brainbase enables businesses to create those AI Employees.

In just one year, we’ve grown to $XM+ ARR and are on track to hit $XXM+ next. Our customers range from SMBs to Fortune 50 enterprises. We’re backed by Y Combinator, 500 Global, and other top-tier firms, with participation from the founders of YouTube and HubSpot, as well as leading YC alumni.

About the role

As part of our founding team, you will have a high agency role in bringing AI to the enterprise: shipping new features, talking to users and shaping company culture for other team members to come.

You will work one-on-one with our CEO and founding team to primarily iterate based on customer feedback, help with infrastructure scaling (cloud and on-premise) and improve our underlying proprietary agent system.

Who’s a good fit?

We think you should apply if the following sounds like you:

- Resourceful – You’ve been known to get a lot done with very little, whether it is time, money or compute

- Resilient – You don’t quit when something is difficult, only when you have realized a better way to do it

- Decisive – You can make informed decisions under stress with incomplete data, and move on to the next task (no hedging)

- L̶i̶k̶e̶ Love difficult problems – You like working at puzzles, chess or anything that you’re not immediately good at

- Fun – You can smile/joke/enjoy yourself through the pain and the slog, and can lift up others even when things are objectively not going well

What we’re looking for?

In addition to the personal qualities mentioned above, this role requires the following:

💻 Must haves

- In SF, or willing to relocate

- US work permit (we do not currently sponsor H1-Bs, OPTs are fine)

- 2+ years of software engineering experience (new grads encouraged since pet projects count)

- Excellence with Typescript & Python

- Some experience with LLMs (OpenAI API, Langchain, HuggingFace, etc.)

- Demonstration of autonomy and entrepreneurial spirit (side projects, previous companies)

💻 Good to haves

- Proficiency in AWS, cloud deployment, CI/CD
