Senior Software Engineer

  2025-10-06     HartleyCo     San Francisco,CA  
Description:

Overview

Our client, a YC-backed startup with a recent $6M seed round, is on a mission to empower non-technical founders to turn ideas into scalable software businesses. Their platform bridges the gap between AI-generated code and production-ready products - delivering not just the build, but the infrastructure, tooling, and go-to-market support to help new companies succeed.

This is a rare opportunity to join a high-caliber founding team (ex-serial founders with a decade of working together) and work on deep, complex engineering problems that make sophisticated tech invisible to end users.

What you'll do

  • Design and build full-stack features from scratch - front-end, back-end, infra, and architecture
  • Architect modular, reusable systems that scale
  • Work closely with product and design to ship quickly without sacrificing quality
  • Collaborate with a small, senior team that values high autonomy and zero fluff
  • Keep pace with the latest technologies and contribute to technical direction
  • Take ownership end-to-end - no “just my piece of the stack” mentality

What we're looking for

  • 4-10 years' experience in software engineering, with strong CS fundamentals
  • Proven 0-to-1 product experience (ideally as a Founding Engineer or early hire at a VC-backed startup)
  • Fluency in TypeScript and React (React Native a plus)
  • Experience with AWS, Docker, Postgres, and scalable architectures
  • Ability to operate without heavy reliance on AI coding tools - you can code and architect from scratch
  • Strong communicator who thrives in high-autonomy, fast-paced environments
  • Based in or willing to relocate to SF (remote possible for exceptional candidates who can attend 3-day on-site sprints monthly)
  • Be part of a high-bar engineering culture - every teammate is senior-level or above
  • Ship products that help thousands of founders bring their ideas to life
  • Competitive comp - salary at the 90th percentile for top performers, plus meaningful equity
  • Work directly with the founders to shape the company's technical future
  • No bureaucracy, no layers - just a flat, hands-on team moving fast
