Subject is reimagining education from the ground up and needs to develop powerful, flexible platforms to deliver engaging virtual high school courses at scale

Requirements

  • 4+ years of senior level experience in full-stack or backend software engineering, with ownership of high-scale production systems.
  • Deep expertise in backend technologies: Node.js (Express/Nest), Postgres (including schema design and performance tuning), and RESTful API design.
  • Proficiency in GCP (or AWS), Docker, and CI/CD tooling for cloud-native deployments.
  • Working fluency with front-end stacks like React/Next.js and TypeScript (you won’t lead on UI, but you’ll integrate with it daily).
  • Startup hunger: You’ve shipped with incomplete specs, debugged in prod, and thrived in ambiguity.
  • Performance mindset: You care about uptime, observability, and delivering value at speed.

Responsibilities

  • Backend Leadership: Architect and implement scalable, maintainable services using Node.js and Postgres. Design and optimize APIs, databases, and job queues that power core business functionality.
  • System Engineering: Build resilient infrastructure in GCP. Leverage Docker, CI/CD pipelines, and infrastructure-as-code to support high uptime and fast iteration.
  • Full-Stack Collaboration: While you’ll focus on backend, you’ll collaborate with frontend engineers (Next.js, TypeScript) to deliver seamless, user-friendly experiences across the stack.
  • Data Stewardship: Design data models and systems that scale with our growth — including user activity tracking, assessment data, and school district reporting.
  • Security & Privacy: Help us build for a K-12 audience by maintaining high standards for data protection, student safety, and compliance with education data regulations.
  • Velocity & Ownership: Operate in fast sprints alongside product and content teams. Own what you build, ship quickly, and iterate even faster.
  • Team Building: Mentor peers and contribute to a high-trust, high-output engineering culture. Set a strong example in code quality, reliability, and communication.

Other

  • 60+ hour weeks? In-office every day? That’s your edge.
  • You thrive in intensity.
  • You believe impact beats pedigree. Your resume is just the starting point — your results will speak loudest.
  • You care, but you perform. We win together.
  • 4+ years of senior level experience
