Job description

Senior Software Engineer — Product & Backend

Location: New York City or San Francisco

Work Policy: Hybrid (Minimum 3 Days In-Office)

Compensation: $250k – $350k Base + Competitive Early-Stage Equity

About the Role

An early-stage startup, growing exceptionally fast with a small and talent-dense team, is hiring Senior Software Engineers to build and own core product from the ground up.

The team is small, senior, and moving quickly. This is a rare chance to join early, take real ownership, and shape both the product and the engineering culture as the company scales.

The work is product and backend focused, roughly 80% application development and 20% systems and platform work. You will build features end to end and own them in production.

What You'll Do
  • Build product end to end in TypeScript and Python
  • Take features from idea to production and own them fully
  • Ship quickly in an environment with very little process
  • Design and evolve backend services as the product grows
  • Improve performance, reliability, and developer velocity
  • Shape architecture, standards, and how the team scales from here
Who You Are
  • 3–5 years of software engineering experience
  • Time spent at high-growth, talent-dense startups
  • Strong coding ability in TypeScript and Python
  • A clear track record of shipping real product you can walk through
  • Strong system design instincts and cross-team collaboration
  • Motivated by ownership and pace over a big-company path
  • Based in or willing to work in-person 3 days per week in NYC or SF
Tech Stack
  • TypeScript
  • Python
  • Modern cloud infrastructure
Notes
  • This is product and application engineering. No Kubernetes or Terraform focus.
  • Visa sponsorship is not available for this role.
  • The team is hiring multiple engineers with an accelerated interview process.
