We care more about demonstrated ability than credentials. Technical Skills * Backend development: Python 3 and web frameworks and APIs (we use Flask) * Databases: Experience with SQL and NoSQL databases * Cloud infrastructure: Google Cloud Platform, or similar cloud platforms * Architecture patterns: Familiarity with domain-driven design, clean architecture, and CQRS is a plus Preferred Experience * Financial systems: Payment processing, fraud detection, or compliance systems * Financial regulations: Familiarity with AML, KYC, PCI DSS, or similar regulations * Banking integrations: Experience with financial APIs and money movement systems (ACH, card networks) * Third-party integrations: Experience building and maintaining integrations with external services * Scale and reliability: Experience with systems processing high transaction volumes, * We're looking for engineers who are excited by complex systems problems and have the educational background and experience to handle sophisticated challenges. * If you're passionate about building mission-critical financial infrastructure and want to have a direct impact on our technical direction, we'd love to hear from you. ## Description We're looking for a Backend Engineer to build and ship features across the financial systems that move real money every day. You'll join a small team of experienced engineers working on our distributed microservices architecture, taking on features across payments, fraud detection, compliance, and user management from design through production. This role is for an engineer who already delivers independently and is ready to take on broader scope. You'll work on larger, cross-domain problems, get real exposure to architecture decisions, and grow quickly in a domain where correctness and reliability matter. What You'll Do * Own features end to end: Design, build, test, and deploy backend features and services across payments, fraud, compliance, and user management, then run and monitor what you ship * Integrate with financial partners and APIs: Build and maintain integrations with banks, card networks, and other third-party services, handling the edge cases that money movement demands * Contribute to design: Write and review technical designs for your own work, participate in architecture discussions, and learn how our domain-driven, event-driven approach fits together * Improve performance and reliability: Find and fix bottlenecks and failure modes across our microservices, and help raise the quality of our tests and observability * Collaborate across teams: Work closely with product and compliance to turn business and regulatory requirements into working software, Remote United States Easy Apply 173K-255K Annually Senior level 173K-255K Annually Senior level Big Data * Fintech * Mobile * Payments * Financial Services Own and deliver highly available, low-latency backend identity systems supporting consumer onboarding, authentication, and verification. Lead quarterly team goals, guide engineers through ambiguous problems, collaborate with product and design partners, monitor system reliability, improve engineering standards, support on-call operations, and mentor team members.
