We are looking for a full stack engineer who wants to help shape the future of private equity and our company. As an early stage engineer you will:

  • Work directly with our founding team.
  • Help design our application architecture.
  • Ship features that our users care about, wherever they are in the stack.
  • Participate in strategy and product ideation sessions, influencing our product roadmap.

  • You enjoy diving deep into the domain, understanding the problem, and focusing on delivering value to the customer.
  • You thrive in a fast paced environment.
  • You like to take ownership and work independently.
  • You are excited about joining an early-stage venture.

Don’t apply if:

  • You want to work on a single layer of the application.
  • You prefer to work on well-defined problems.
  • You need clear, pre-defined processes.
  • You prefer a low-pressure environment.
