Job description

Endeavor is real-world enterprise AI.
Our software is the distribution layer for powerful AI models that will build the world.
Our belief is that AI will power many applications in legal, healthcare, and finance. But none are more important than building AI that can build the world around us. Especially the physical infrastructure that will accelerate the development of AI.
We focus on the building materials market, which is suffering from manual quoting, order entry, and pricing. These are a double whammy. They lose revenue for missed quotes and mispriced products. And they pay tons of people to make quotes and enter orders. AI solves that, so our product is flying off the shelves. After we dominate this market, we'll go to other industries. But we have to win this market first - if we don't, we don't get to the next level.
While labs build the models of the future, we build the last-mile delivery for them. We must model complex environments, deliver reliable results, and bridge the gap between models and the antiquated ecosystems in which they must operate.
Our Principles
  • We are bold, especially when the world tells us what we're doing is impossible.
  • We are truth-seeking, choosing clarity over comfort.
  • We will win. And we work really hard to win.

The Role | Staff Software Engineer
As a Staff Software Engineer at Endeavor, you will help optimize our application and make our key business cases run faster. You'll find the bottlenecks in a messy code base and make improvements independently. This is an opportunity to work with a high level of autonomy designing database schemas, improving code quality, and improving our existing design.
What We Require
  • Experience designing database schemas, solving performance issues, and improving code quality.
  • Experience building a full stack feature.
  • Experience with Python web apps (FastAPI/Flask)
  • Experience with Postgres and SQLAlchemy.
