Experience with SQL Server, relational database design, and performance optimization.
Strong understanding of fintech integration concepts including OAuth 2.0, webhooks, API security, and financial data workflows.
Experience with consumer lending, financial systems, or fintech platforms is strongly preferred.
Comfortable using AI-powered development tools for coding assistance, debugging, automated testing, code reviews, documentation, and engineering productivity improvements.
Excellent problem-solving, communication, and cross-functional collaboration skills.
Preferred Technical Skills:
Experience with consumer lending, loan origination systems (LOS), or financial institution software.
Familiarity with credit decisioning engines, dynamic scoring models, and automated underwriting workflows.
Cloud and Azure development experience.
CI/CD pipeline design and DevOps practices.
Automated testing methodologies including unit, integration, and contract testing.
