Position Overview

We are seeking a Software Engineer (Contractor) for the hands-on execution of approved architecture and design changes across the Loan IQ integrations platform, with a strong emphasis on payments and downstream system integrations.

The engineer is expected to operate with minimal oversight. Apart from this core responsibility, this role is expected to manage BAU activities along with other developers on the team.

This is a delivery-critical role, intended for an experienced engineer who has successfully implemented complex integration architectures in regulated financial environments.

• Identify design gaps, implementation risks, and operational concerns early and propose pragmatic solutions.

• Replace or reduce direct SQL-based integrations by leveraging APIs.

• Refactor existing integrations to address current-state limitations

• Implement consistent logging, error handling, and monitoring to improve root-cause analysis and operational support.

• Design integrations to be testable, supporting Unit testing, Integration testing, and End-to-end automated testing

• Integrate solutions into CI/CD pipelines, enabling automated builds, testing, and deployments.

• Ensure solutions meet non-functional requirements (performance, reliability, security, auditability).

• Review code and designs from other engineers, ensuring adherence to standards and architecture.

• Collaborate and provide clear technical communication to stakeholders, including risks, dependencies, and progress

What You’ll Need to Have:

• 6+ years (in handling the responsibilities specified above) hands-on software engineering experience in enterprise environments. Overall 10+years is preferred, but not mandatory.

• Proven track record executing architecture-driven integration transformations, not just feature development.

• Deep experience with integration patterns and technologies, including:

• RESTful APIs

• SOAP and XQuery-based APIs

• File-based integrations (SFTP, batch processing)

• Strong development experience with .NET (Core / modern .NET) and related enterprise frameworks.

• Solid understanding of processing flows and transactional system behavior.

• Experience implementing logging, monitoring, and error-handling frameworks in distributed systems.

• Comfortable working independently and owning delivery end-to-end.

Key Skills:

• Designing and developing Fullstack web apps using .Net MVC, C#, SQL Server , Angular

• Designing and developing complex web applications, SSO Auth, Data modeling using .Net EF Core, TDD

• Database (preferably Oracle and SQL server), SQL Scripting

Preferred/Desired Skills:

• Experience with cloud or hybrid architectures (Strongly preferred).

• Prior work on Loan IQ.

• Experience modernizing Windows-scheduled or batch-based jobs into more observable and resilient architectures.

• Background in financial services or banking technology, including audit and regulatory awareness.
