Role Description We are seeking a senior software engineer to modernize a legacy COBOL-based ERP into C#/.NET using an AI-first approach, and to build an agent-driven modernization workflow that enables repeatable conversion and rigorous validation at scale. This role is AI-first by design: you will use modern AI-assisted development tools and agentic workflows to accelerate translation, refactoring, and test creation, and you will operationalize them into a “factory” integrated with automated testing, parity/reconciliation checks, and clear mismatch reporting. You will own delivery of validated conversions and the agentic modernization factory with minimal oversight, driving measurable progress through throughput, parity pass rate, and mismatch burn-down. Responsibilities - Experienced .NET Developer to design and build an enterprise-grade application. - Responsibilities include creating foundational components like modular architecture, event-driven systems, repository patterns, and LINQ capabilities for multiple applications. - Develop business processes using Domain-Driven Design (DDD). - Expert in Object-Oriented Design and SOLID principles. - Knowledge of Design Patterns: Repository, Unit of Work, Observer/Pub-Sub, Factory, Dependency Injection, Result Pattern. - Proficient in Generics, Reflection, and Expression Trees for dynamic components. - Strong experience with LINQ and dynamic query building. - Familiarity with Domain-Driven Design (DDD) and domain events. - Experience in developing repository layer for secure, auditable data access using ORM. - Experience writing comprehensive test suites for components. - Hands-on experience with AWS services such as EventBridge, Lambda, and API Gateway, along with expertise in hybrid networking solutions including PrivateLink, VPC, and Site-to-Site VPN. - Design an asynchronous integration gateway utilizing AWS tools, while establishing canonical data contracts. - Implement micro-frontend (MFE) applications using React and TypeScript, with an emphasis on user self-service functionalities. - Develop event schemas and establish publish/subscribe patterns for domain events via EventBridge. - Analyze and understand legacy COBOL, Genero 4JS programs (batch jobs, online programs, copybooks, file processing, and business rules). - Translate and modernize into clean, maintainable C#/.NET aligned to agreed architecture patterns. - Use AI-assisted tools to accelerate translation/refactoring/test generation, applying human judgment and review to ensure correctness. - Build an agentic factory for Self-Correction Loops that can analyze test failures, look back at the source code in Cobol or Genero and autonomously refactor C# fixes. - Automated test generation and execution. - Output diffing and reconciliation (legacy vs modern). - Debug parity mismatches and performance issues; drive fixes to achieve functional equivalence. - Collaborate with SMEs, QA, and stakeholders to clarify requirements and edge cases. - Document migrated components, assumptions, and modernization decisions. Qualifications - 5+ years of professional software development experience. - Strong hands-on experience with C# and .NET. - Hands-on experience with AWS services. - Ability to read and understand COBOL to accurately translate business logic. - Strong experience with SQL Server and relational database concepts. - Experience using AI-powered coding assistants (e.g., GitHub Copilot, Cursor) and Prompt Engineering in a professional context. - Experience building automation workflows/pipelines that orchestrate multi-step processes. - Strong analytical, debugging, and problem-solving skills; comfort working with incomplete legacy documentation. - Experience building parity harnesses, Deterministic Testing or Property-Based Testing. Requirements - Experience with modernization or large-scale migration projects. - Fund accounting / public-sector finance / financial systems domain experience. - Familiarity with Enterprise Resource Planning applications. Benefits - Comprehensive Insurance Coverage (including Medical, Dental, Vision, Pharmacy benefits, Life Insurance and AD&D). - Flexible Spending Accounts and Health Savings Accounts. - Short-Term Disability and Long-Term Disability. - Comprehensive 401(k) plan. - Generous Parental Leave. - Unrestricted paid time off (known as Discretionary Time Off - DTO). - Wellness Program, including ClassPass & Employee Assistance Program. - Tuition Reimbursement. - Optional Benefits: Pet Insurance, Identity Theft Protection, Student Debt Repayment Program and Prepaid Legal coverage. - A reasonable estimate of the base compensation range for this position is $92,800 - $170,300 USD.
