Want to make AI just work? 

Most enterprise AI stops at a chat box. Ask it something real about your business and it has no idea what your company knows, so you paste in context and hope. We are building the layer that fixes that across any model.

Coworker builds a context graph across every system a company runs. Closed frontier models when the work demands it, open US-hosted models when it does not. Same quality of output, roughly 5x the tokens for the same spend. When a better model ships, our customers get it automatically.

It is working. We are changing the way people work. AI is not an add-on, it is the product, and with Coworker you unlock true native access that brings work into a new era.

We are honest about the stage. This is early, the surface area is enormous, and we ship fast enough that some weeks are heavy. We are working at the forefront of AI development, building not only our product but our company around true AI native workflows.

About the job

We need a talented, ambitious, hard-working senior software engineer with 4+ years of experience who can help us build the foundation for the next era of work. We need someone who wants to change how the world works, one company at a time.

You are that person.

You are a hungry full stack software developer who is capable of thought leadership and high-quality code output, but who is also obsessed with making customers happy, and will do whatever it takes to make it happen. You are also autonomous and happy to take on big, ambiguous problems as one of the first engineers at a fast-growing startup.

You’re willing to work nights and weekends if needed to get key projects over the line. But you (like us!) are more than your code and your hard work! You love building a culture where people love to work but believe in putting people first while having a huge amount of fun while you do your job.

You will be given substantial amounts of tokens to accomplish your job. We're looking for people who are willing to explore and maximize the value of those tokens.
