Job Description

Staff Backend / Platform Engineer

Full-Time | Hybrid | New York City or Austin

We’re seeking a seasoned Backend/Platform Engineer to help build the foundation of a new API-driven platform that simplifies how money moves through a complex, high-stakes domain. You’ll work across systems that touch everything from external developer APIs to internal transaction orchestration—laying the groundwork for reliable, secure, and scalable services as we grow.

What You’ll Do

Design and build core backend services powering mission-critical money movement workflows

Own external-facing APIs and webhook infrastructure used by partners and third parties

Drive integration with external services and internal platforms to ensure clean, reliable data flows

Collaborate across product and engineering teams to build abstractions balancing flexibility with simplicity

Operate in a fast-paced, collaborative environment with high standards and low ego

Help scale our systems from tens of millions to hundreds of millions in volume

Contribute to architectural decisions, developer tooling, and API reliability from day one

What We’re Looking For

8+ years of backend or platform engineering experience, ideally in fast-paced or startup environments

Strong experience building and scaling REST APIs and webhook systems

Experience with transactional systems, reconciliation, or multi-service workflows (e.g., payments, event processing)

Proficiency in modern backend stacks (e.g., TypeScript, Node.js, Ruby on Rails, PostgreSQL)

Familiarity with cloud infrastructure (AWS), containerized apps, CI/CD workflows, and system monitoring

Strong testing practices and experience with GraphQL or WebSocket APIs is a plus

Clear communicator with a collaborative mindset and thoughtful decision-making in ambiguity

Comfortable working onsite 3–5 days/week in New York City or Austin
