Description

About Us OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. Our execution has been exceptional, and we’re scaling at a remarkable pace. 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. Responsibilities & Expectations Backend Engineering: Expand, secure, and optimize backend services that power internal admin tooling and customer-facing workflows. Scalability & Reliability: Ensure platform services are resilient, fault-tolerant, and performant as OpenFX grows. Security & Compliance: Harden access controls, approvals, and backend processes to meet financial-grade standards. Cross-Functional Support: Partner with product managers, frontend engineers, and other pods to deliver solutions across the org. 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 Node.js 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.
