[Hiring] Senior AI Software Engineer @Tower Loan

Role Description

The Senior AI Software Engineer will play a leading role in the ground-up rewrite of Tower Loan’s loan origination and servicing platform, applying modern modular design principles, microservices, and event-driven architecture to support enterprise-scale deployment serving 1,000+ users across hundreds of locations. This role will champion an AI-first approach across requirements analysis, architecture, development, testing, and delivery.

• Design and develop Tower Loan’s next-generation loan origination and servicing platform using C#, .NET 10 or later, ASP.NET Core, SQL Server, and modern UI frameworks such as Blazor or React.
• Apply AI-first development practices throughout the software lifecycle, including requirements refinement, business rule extraction, architecture analysis, code generation, automated testing, refactoring, and documentation.
• Lead the technical design and delivery of complex features, translating business requirements into practical architecture, implementation plans, and reliable software.
• Design modular services with clear domain boundaries, reusable components, and well-defined APIs that support independent deployment, scalability, and maintainability.
• Implement event-driven communication and asynchronous processing using Kafka or comparable messaging technologies, with appropriate handling of retries, duplicate messages, failures, and data consistency.
• Engineer applications for enterprise-scale use across hundreds of locations, addressing concurrency, performance, resilience, and operational reliability.
• Analyze legacy .NET Framework applications to identify business rules, dependencies, and workflows, ensuring required functionality is accurately incorporated into the new platform.
• Support data migration, integration, and phased transition activities to maintain business continuity as the new platform replaces existing capabilities.
• Build responsive, accessible user interfaces that simplify loan origination, account servicing, payment processing, and other operational workflows.
• Design and optimize SQL Server schemas, stored procedures, views, queries, and indexes, emphasizing data integrity, transaction consistency, performance, and version control.
• Develop and integrate AI capabilities into business applications, including intelligent assistants, document processing, knowledge retrieval, and automated workflows.
• Build and maintain integrations with payment processors, document management and eSignature platforms, messaging services, analytics tools, and other internal and third-party systems.
• Independently review and validate AI-generated code and other outputs for correctness, security, performance, and maintainability.
• Implement appropriate controls for AI functionality, including access restrictions, sensitive data protection, output validation, evaluation, monitoring, and human review where warranted.
• Create and maintain automated tests, collaborate with QA, and validate that delivered functionality meets intended business outcomes and established quality expectations.
• Conduct code reviews, mentor other engineers, and contribute to engineering standards, architectural decisions, and continuous improvement.
• Troubleshoot complex application and distributed system issues using logging, metrics, and tracing to identify root causes and improve reliability.
• Contribute to CI/CD pipelines, deployment automation, technical documentation, data models, and API specifications.
• Implement security and privacy controls consistent with company policies and applicable regulatory requirements.
• Perform all other duties as assigned.

Qualifications

• Advanced proficiency in C# and modern .NET, including ASP.NET Core, API development, asynchronous programming, dependency injection, and application performance optimization.
• Strong full-stack development skills, including Blazor or React and supporting web technologies such as HTML, CSS, JavaScript, or TypeScript.
• Strong SQL Server development and troubleshooting skills, including relational data modeling, indexing, query optimization, and transaction management.
• Strong understanding of modular software design, microservices, REST APIs, event-driven architecture, domain-driven design, and clean architecture principles.
• Practical understanding of distributed systems, including service boundaries, asynchronous messaging, fault tolerance, idempotency, and eventual consistency.
• Ability to design applications for substantial concurrent usage and deployment across geographically distributed business locations.
• Demonstrated ability to use AI development tools effectively while maintaining ownership of technical decisions, code quality, testing, and delivered results.
• Practical understanding of large language model integration, prompt design, retrieval-augmented generation (RAG), tool calling, and the limitations of AI-generated output.
• Ability to extract and validate business rules from existing applications and translate them into clear requirements and maintainable implementations.
• Experience with automated testing, source control, code reviews, and CI/CD pipelines.
• Excellent debugging, analytical, and problem-solving skills, with the ability to evaluate technical tradeoffs and resolve complex issues.
• Ability to work independently, lead technical efforts, mentor teammates, and communicate effectively with technical and business stakeholders.
• Demonstrated integrity, discretion, and professionalism when handling sensitive or confidential information.
