Job description

Concord sits at the center of the credit market ecosystem. We provide loan servicing, backup servicing, and capital markets administration for specialty finance lenders, institutional investors, and asset managers. Our clients include originators across fintech, solar, home improvement, equipment finance, and other specialty asset classes. When a lender needs a trusted partner to service their portfolio or a trustee needs real-time reporting, they call Concord.

We're hiring a Senior .NET Software Engineer to design, build and maintain the financial applications our business users rely on every day, working across SQL Server, Snowflake and cloud services.

You'll join a small, senior-leaning team that owns the core applications behind a financial services business. The work is varied: new features on modern .NET services, integrations with internal and third-party systems, and data pipelines feeding analytics. You'll work with Product, Compliance, Security and Data partners, have direct access to the business users you build for, and shape how we design, test and ship.

Responsibilities:

• Design, build and maintain applications and APIs in C# on .NET (ASP.NET Core, Web API, background services)
• Write testable, well-documented code and review peers' work against agreed standards
• Lead technical design for multi-component features and mentor other engineers
• Build and maintain integrations with internal and third-party systems through APIs and messaging
• Own features end to end: refine requirements with business partners, estimate, build, test, deploy and support in production
• Collaborate with Product, Compliance, Security and Data teams to translate business and regulatory requirements into technical solutions
• Implement security practices that protect sensitive financial data (encryption, authentication, authorization)
• Apply regulatory and audit requirements, such as data retention and access controls, in system design
• Troubleshoot production issues, find root causes, and fix the underlying problem rather than the symptoms
• Keep current with security trends and emerging technologies, and recommend what is worth adopting
• Language requirements: fluent English
  

Nice to Have

• Cloud experience (Azure or AWS), including containers, serverless functions or infrastructure as code
• TypeScript experience, including front-end frameworks or Node.js tooling
• Blazor, Angular or React for front-end work
• Messaging and integration patterns (queues, event-driven design, SFTP and batch file processing)
• Experience with Snowflake, ETL/ELT tooling or other data warehouse work
• Experience in lending, banking, payments, insurance or investment systems
• A background in operations or another business function, which helps you understand the problems we solve
