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

- 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

- 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.
