About the Role

We're looking for a highly motivated Founding Software Engineer to help build and scale sophisticated software products at an early-stage technology startup.

You'll work across full-stack engineering, backend systems, data infrastructure, and automation, with significant ownership over product architecture and technical decisions.

This is a hands-on role for an engineer who enjoys building from scratch, solving complex real-world problems, and shipping production-quality software in a fast-moving environment.

  • Develop scalable backend services, APIs, and data infrastructure.
  • Build internal platforms and tools that streamline complex business and operational workflows.
  • Work with real-time data, integrations, and automation systems.
  • Own features and technical initiatives from concept through deployment.
  • Collaborate with cross-functional engineering teams to solve complex technical problems.
  • Make architectural decisions and improve system performance, reliability, and scalability.
  • Identify high-impact opportunities and independently drive solutions.

What We're Looking For

  • 2+ years of professional software engineering experience, with a strong record of shipping production software.
  • Strong full-stack development experience, particularly with TypeScript.
  • Backend proficiency in Python or Go.
  • Experience designing and building applications, APIs, and backend systems end-to-end.
  • Strong understanding of data modeling, system architecture, and software engineering fundamentals.
  • Demonstrated ownership of products or substantial technical features.
  • Ability to work independently and solve ambiguous problems.
  • High agency, strong product instincts, and a bias toward execution.
  • Comfortable working in an early-stage startup environment.
