Our team comes from world-class institutions, including J.P. Morgan, Goldman Sachs, FalconX, PayPal, Affirm, Polygon, Kraken, and Nium. Accel, Lightspeed, NfX, and other top-tier investors back us.

Role Overview

We are seeking a Senior Backend Engineer to join our Platform Pod, a horizontal team that supports the cross-functional needs of the organization. This role focuses on strengthening and extending backend systems that enable internal admin tooling, customer workflows, and cross-pod initiatives.

You will play a critical part in ensuring that OpenFX's platform remains secure, scalable, and reliable, while supporting projects that cut across trading, security, product, and operations. This is a high-ownership role where your fintech experience and technical expertise will directly shape how the company scales.

  • Org-Wide Impact: Contribute engineering capacity to horizontal projects that don't fit neatly into a single pod, relieving strain on core trading and growth teams.
  • Technical Excellence: Uphold high standards for code quality, reviews, and engineering culture.
Qualifications
  • Bachelor's or Master's degree in Computer Science, Engineering, or related field.
  • 5+ years of professional backend engineering experience, with at least 2 years in a senior role.
  • Strong expertise in distributed systems, microservices, and event-driven architectures.
  • Proficiency in with TypeScript.
  • Experience with messaging systems (Kafka, Redpanda, RabbitMQ, or similar).
  • Experience designing and maintaining REST/gRPC APIs in production.
  • Ability to design for performance, scalability, and reliability in production systems.
  • Strong ownership mindset and ability to work in a fast-paced, high-accountability environment.
What Will Help You Stand Out
  • Full stack capability (React, TypeScript, or similar).
  • Background in compliance-driven workflows, admin tooling, or customer account management.
  • Contributions to cross-team or platform-wide engineering projects.
  • Familiarity with cloud-native architectures and Kubernetes-based deployments.
What We Offer
  • Competitive compensation, including equity.
  • High ownership of platform-critical systems that support the entire org.
  • Opportunity to build tooling and services that impact both internal teams and external customers.
  • Fast-paced, collaborative environment with top-tier engineering and product talent.

We are committed to building a diverse and inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
