Software Engineer

Summary

Senior Backend Engineer building scalable, developer-first commerce infrastructure using Node.js and Postgres, with a focus on payments and distributed systems.

We're looking for a Senior Backend Engineer to join a fast-moving infrastructure team building highly flexible, developer-first commerce systems. This role is ideal for someone who thrives in high-ownership environments, enjoys solving complex technical challenges, and has deep experience working on products with significant architectural complexity.

Responsibilities:

  • Design, build, and maintain backend systems using Node.js and Postgres
  • Architect and evolve complex distributed systems that support large-scale workflows, data models, and APIs
  • Collaborate closely with product and developer experience teams to deliver features that unlock new capabilities for customers
  • Work with early customers to understand use cases and guide them through architectural decisions
  • Build reliable, performant services with strong observability, testing, and security practices
  • Contribute to internal engineering standards, tooling, and documentation
  • Identify bottlenecks, propose solutions, and drive improvements across the infrastructure
  • Help shape foundational components of a managed services platform for hosted commerce infrastructure

Must-Haves:

  • 8+ years of backend engineering experience with strong proficiency in Node.js or Postgres
  • Based in East Coast Americas or Europe
  • Experience working with complex products, such as:
  • Developer tooling (e.g., Snyk, Sentry, Postman, Prisma)
  • Orchestration or workflow tooling (e.g., Temporal, Alloy)
  • Payments infrastructure (e.g., Stripe, Checkout, Adyen)
  • Delivery or ride-sharing applications
  • Hands-on experience building large distributed systems

Experience scaling early-stage startups, ideally from Seed through Series A/B

Strong individual contributor (IC) background; recent roles should be hands-on

Familiarity with e-commerce, payments, logistics, or API-driven infrastructure is a plus

Nice-to-Haves:

  • Based in NYC
  • IC (individual contributor) role in the last two positions
  • Ex-CTO or founder experience
  • Experience with distributed systems
  • Commerce experience

What You'll Bring:

  • Strong technical judgment with the ability to simplify complex problems

  • A product mindset and deep appreciation for developer experience

  • High ownership, autonomy, and a bias for action

  • Excellent communication and cross-functional collaboration skills

Why This Role Is Exciting:

You'll be working on the core technology behind a new generation of commerce infrastructure. You'll have meaningful ownership over architecture, influence foundational engineering decisions, and contribute to a team that values craftsmanship, speed, and clarity.
