Team Overview Our Research & Development (R&D) team is the technical talent at the heart of our product suite, overseeing the product development lifecycle from concept to delivery. From engineering to quality assurance to data science, the R&D team ensures our customers seamlessly use our products and can depend on their consistency. Responsibilities We are establishing an ERP Platform team focused on modernizing our core architecture. This initiative encompasses a multi‑year effort involving various components: an event‑driven integration gateway, domain‑driven APIs, contemporary MFE‑based user interfaces, and a strategy to decommission legacy application layers. We are seeking a high‑impact Staff Software Engineer to lead the technical execution of our ERP modernization strategy. This is a “Builder‑Architect” role focused on converting our core COBOL (BusinessPlus) and Genero (eFinancePlus) products into a modern, domain‑driven C#/.NET architecture. You will not just be writing code; you will be building the Agentic Modernization Factory—a suite of AI‑driven tools and pipelines that automate the translation, refactoring, and validation of legacy business logic at scale. You will also architect the “Unified Bridge” that allows our modernized services to operate seamlessly across 1,000+ customer instances, whether deployed in our cloud or on‑premise. Key Responsibilities: 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. This includes developing adapters for data normalization and defining API conventions across various endpoints. Implement micro‑frontend (MFE) applications using React and TypeScript, with an emphasis on user self‑service functionalities. Ensure comprehensive deployment and validation within a specified testing framework. Develop event schemas and establish publish/subscribe patterns for domain events via EventBridge. Create connector Lambdas to facilitate event translation and integrate resilience patterns for robustness. Engage in a comprehensive SaaS platform consolidation strategy by utilizing established integration patterns. Define and promote modernization practices that can be seamlessly adopted by different teams across the organization. Design and develop the next generation of our enterprise ERP application platform. Modernize legacy screens and build new UI components using React while integrating with .NET/C# backend APIs. Hands‑on experience with React (hooks, functional components, custom hooks). Strong proficiency in TypeScript for type‑safe frontend development. Experience with state management solutions (Redux, React Query, etc.). Deep understanding of reactive programming patterns. Experience building complex enterprise UI components. Familiarity with screen layout generators and dynamic UI rendering. Ability to develop screen plugins and custom business logic for subsystems. Create responsive layouts for fixed and fluid container patterns. Experience with SCSS/SASS styling and theming for enterprise applications. Understanding of data source patterns (CRUD operations, record navigation, validation). Experience with unit testing using Jest, Karma, or Jasmine. Experienced .NET developer to design and build an enterprise‑grade application. Expert in Object‑Oriented Design and SOLID principles. Knowledge of design patterns: Repository, Unit of Work, Observer/Pub‑Sub, Factory, Dependency Injection, Result Pattern. Experience in developing a repository layer for secure, auditable data access using ORM. Strong experience with LINQ and dynamic query building. Build the AI Factory: Design and implement agentic workflows (using LLMs and orchestrators like Semantic Kernel) to automate the conversion of COBOL and Genero source code into clean, maintainable C#. Architect Hybrid Connectivity: Build the integration layer (API Gateway, EventBridge, and SQS) that connects modernized C# services to legacy SQL Server and IMAGE databases across cloud and on‑premise environments. Implement Parity Automation: Develop “Golden Master” testing frameworks that run legacy and modern code in parallel to ensure 100% financial and functional correctness. Modernize Service Interactions: Redesign point‑to‑point legacy integrations into a unified, event‑driven backbone to improve system interoperability and “better together” outcomes. Lead the “Paved Path”: Create reusable patterns and shared services (e.g., Secure PII Payload handling) that other developers will use to modernize specific ERP domains like Employee and Finance. Qualifications Minimum Qualifications Expert with 8+ years of professional experience in building enterprise frameworks with extensive experience in orchestration using GenAI to modernize legacy systems. Hands‑on experience with AWS services. AWS Hybrid Cloud Mastery: Hands‑on experience with AWS EventBridge, Lambda, API Gateway, and hybrid networking (PrivateLink, VPC, Site‑to‑Site VPN). Hands‑on experience with C# and .NET. AI/LLM Integration: Proven experience building applications that leverage LLM APIs (OpenAI/Anthropic) or AI orchestration frameworks (Semantic Kernel, LangChain, or similar). Legacy Data Fluency: Ability to read and interpret legacy code structures (COBOL copybooks or 4GL logic) and map them to modern relational schemas in SQL Server. DevOps & Fleet Management: Experience building automated CI/CD pipelines (GitHub Actions/Azure DevOps) for deploying and managing software across a large fleet of customer instances. Preferred Qualifications Experience with AWS Blu Age or other automated legacy‑to‑cloud transformation tools. Background in Fund Accounting or Public Sector ERP systems.
