Job Summary:
EVAPCO, Inc. is seeking a Full Stack Software Developer to design, build, and support modern applications that connect manufacturing operations with enterprise systems, focusing on ERP integration. The role involves developing solutions across web, desktop, and mobile platforms using Microsoft technologies to enhance manufacturing workflows and data integrity.
Responsibilities:
• Build and maintain web applications using ASP.NET Core MVC and/or modern Blazor architectures (Server / WebAssembly / Hybrid as appropriate).
• Develop desktop applications in WPF for operations/engineering use cases where rich Windows UI and device connectivity are required.
• Create cross-platform mobile/desktop apps using .NET MAUI (including Blazor Hybrid patterns when useful for shared UI).
• Implement clean architecture patterns (layering, DI, testable components) and contribute to consistent coding standards and review practices.
• Deliver solutions that support manufacturing workflows (e.g., production execution, labor capture, material movement, quality checks, traceability, work instructions).
• Integrate with OT data sources (examples may include machines/sensors, HMI/SCADA/MES components, barcode/RFID systems, weigh scales, label printers, industrial PCs).
• Prioritize reliability, performance, and usability in environments with intermittent connectivity and 24x5/24x7 operational needs.
• Design and build robust integrations between OT applications and ERP (and related systems such as inventory, costing, purchasing, scheduling, and shipping).
• Develop and consume REST APIs, event-driven interfaces, and batch processes to synchronize master data and transactions.
• Ensure data integrity, auditability, and traceability for operational and financial impacts (e.g., cycle counts, WIP, inventory adjustments). (ERP/MES integration emphasis aligns to common manufacturing integration role expectations.)
• Develop data access layers and optimize queries/stored procedures using SQL Server (or other enterprise databases as applicable).
• Support reporting and operational dashboards (e.g., KPIs, downtime reasons, throughput, inventory accuracy).
• Implement authentication/authorization and secure coding practices; support enterprise identity integrations (e.g., Microsoft Entra ID where used).
• Follow change control and validation practices appropriate for manufacturing systems where production uptime matters.
Qualifications:
Required:
• 3+ years of professional software development experience (or equivalent demonstrated capability).
• Strong proficiency in C# and modern .NET development practices.
• Hands-on experience building applications with: ASP.NET Core MVC (web), Blazor (Server/WASM/Hybrid), WPF (desktop), .NET MAUI (mobile/cross-platform).
• Solid experience with SQL Server and relational data modeling.
• Experience building/consuming RESTful APIs and working with JSON/XML.
• Familiarity with Git-based source control and modern SDLC practices (CI/CD, code reviews, testing).
Preferred:
• Experience in manufacturing environments and/or with OT systems (MES/SCADA/HMI, shop-floor data collection).
• Proven track record integrating systems with ERP (data synchronization, transactional integrity, error handling/retries).
• Exposure to industrial protocols/connectivity patterns (e.g., OPC UA, MQTT) or device integration (barcode scanners, label printers).
• Cloud experience (Azure) and modern deployment patterns.
