• Build Scalable Systems: Optimize backend services for high performance, ensuring that the platform scales efficiently to handle large volumes of data and transactions from our financial customers.
• Continuous Integration and Deployment: Work with CI/CD pipelines to automate testing, integration, and deployment processes, enabling rapid yet reliable release cycles.
• Security and Compliance: Implement strong security measures and ensure the platform adheres to industry standards, including compliance with SOC 2, BSA/AML, and other relevant banking and lending regulations. You will be responsible for safeguarding customer data and sensitive information.
• Collaborate Across Teams: Work closely with product managers, frontend engineers, and other stakeholders to ensure the backend systems meet business and customer requirements. You will also work with cloud and DevOps teams to ensure the platform’s smooth deployment and operation.
