You'll work across the entire stack to create solutions that responsibly extend credit to businesses while managing billions of dollars in credit exposure. Our team owns the complete credit experience, including the underwriting engine that evaluates applications and sets limits, financial connectivity systems that integrate with banks to pull real-time data, ML-powered credit models that assess risk, customer-facing tools for managing credit limits, and internal platforms that enable our teams to manage risk at scale. You'll be working on high-impact, technically challenging problems: building real-time data pipelines that process millions of financial transactions, serving ML models with strict latency requirements, designing event-driven architectures for credit decisioning, and creating intuitive customer experiences for complex financial workflows. Where you'll work This role will be based in our Seattle office. We are a hybrid environment that combines the energy and connections of being in the office with the benefits and flexibility of working from home. We currently require a minimum of 3 days per week in the office - Monday, Wednesday and Thursday. As a perk, we also have up to four weeks per year of fully remote work. Responsibilities * Build and maintain critical financial infrastructure, including bank connection integrations (Plaid, Finicity, Teller), financial statement processing systems, and real-time transaction data pipelines. * Develop and optimize the underwriting engine that powers credit decisions for thousands of businesses, ensuring sub-second latency and high reliability. * Implement customer-facing features for credit limit management, bank connections, and financial data collection in our React/TypeScript dashboard. * Collaborate with Credit Risk, Capital Markets, and Product teams to translate business requirements into scalable technical solutions. * Design and build internal tooling for Operations and Portfolio Management teams to manage credit risk and handle edge cases. * Own problems end-to-end, from user experience and API design to data models, scalability, and ongoing observability. * Work with ML models in production, integrating credit risk models (PD models, affordability frameworks) into real-time decisioning flows. * Participate in on-call rotation and maintain high operational standards for mission-critical systems. ## Related Videos - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Kubernetes and Microservices with Multi-Model Databases](https://www.wearedevelopers.com/videos/382-kubernetes-and-microservices-with-multi-model-databases) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How Much Does a Software Engineer Make?
