About the Role We’re looking for Software Engineers with 2+ years of backend engineering experience to help build financial infrastructure powering billions of dollars in nonprofit payments.


You’ll own systems end-to-end—from architecture and implementation to production—while working closely with founders, product, and engineering leadership. This is a high-autonomy environment where strong technical judgment, clear communication, and a bias toward shipping are highly valued. What You’ll Do


  • Design, build, and own scalable backend services and APIs.
  • Contribute to architecture, engineering standards, and infrastructure decisions.
  • Build reliable systems using Go, Node.js, PostgreSQL, REST, and gRPC.
  • Develop and operate containerized services with Docker and Kubernetes.
  • Improve monitoring, observability, and real-time alerting.
  • Work across the platform rather than within a narrowly defined product silo.
  • Collaborate directly with founders and leadership to solve complex technical problems.


What We’re Looking For Required:


  • 2–10 years of professional backend/software engineering experience.
  • Bachelor’s degree in Computer Science, Engineering, or another technical field.
  • Proven experience building and owning scalable backend systems end-to-end.
  • Production experience with Docker and Kubernetes.
  • Experience working in a high-growth technology environment.
  • Strong communication, problem-solving, and technical decision-making skills.
  • Ability to work onsite in NYC Monday–Thursday.


Nice to Have:


  • Experience in fintech, payments, or financial infrastructure.
  • Strong proficiency in Go or Node.js.
  • Experience with AWS, Terraform, PostgreSQL, REST APIs, or gRPC.
  • Experience operating production systems in a cloud-native environment.


Why Join?


  • $180K–$230K base salary + competitive equity
  • High ownership and autonomy
  • Direct access to founders and engineering leadership
  • Opportunity to work on financial infrastructure at significant scale
  • Broad exposure across backend, infrastructure, and product engineering
  • NYC hybrid environment with meaningful in-office collaboration
