• Entity Framework Core best practices
• Collaborate closely with product management, UX/design, and QA engineering from concept through delivery
• Contribute to:
• architectural discussions
• design reviews
• technical documentation (including ADRs)
• Mentor other engineers and help raise the technical bar through code reviews and knowledge sharing
• Support additional engineering initiatives, duties, and projects as needed

Technical Environment

• Back-end:C# / .NET

• Strong focus on code quality, security, maintainability, and system ownership
• Excellent collaboration and communication skills across cross-functional teams
• This role requires daily, hands-on use of AI-assisted engineering. You are expected to:
• • Use GitHub Copilot (IDE and CLI) as a default part of your development workflow
• • Author and maintain structured context files (PRDs, design docs) that guide AI agents toward
• accurate output
• • Orchestrate AI agents to generate code, scaffold tests, review pull requests, and identify defects
• • Decompose complex work into planning and execution steps that AI can accelerate
• • Exercise strong engineering judgment over all AI-generated output—AI is treated as a junior
• collaborator whose work you guide, review, and refine

Preferred Qualifications

• Experience in financial services, lending, fintech, or another regulated industry
• Experience working in complex enterprise platforms with legacy integrations and modern cloud-native services
