Job description

2077 Associate Software Architect/Senior Engineer (VB.NET/.NET)

The Associate Software Architect is a hands-on senior engineer and developing technical architect who supports the design, delivery, and modernization of PVS enterprise business applications. Working closely with the Lead Developer/Architect, this person serves as a capable technical counterpart: implementing production code, resolving complex application issues, translating business needs into practical designs, and gradually taking ownership of defined solution areas. The environment includes existing VB.NET/.NET Framework and Microsoft SQL Server applications, with a strategic move toward C#, modern .NET, and Blazor. Architecture decisions must respect on-premises infrastructure, existing integrations, and day-to-day delivery obligations.

Essential Job Functions

• Design, develop, test, and support application enhancements, integrations, and defect corrections; remain an active contributor to production code.
• Work alongside the Lead Developer/Architect to turn business requirements into feasible technical designs, implementation tasks, estimates, and dependencies.
• Maintain and enhance existing VB.NET/.NET Framework and ASP.NET applications while building new capabilities in C# and modern .NET as modernization advances.
• Contribute to enterprise application modernization through practical incremental migration, reusable application patterns, and careful coexistence of legacy and new components.
• Develop and review Microsoft SQL Server queries, data access logic, stored-procedure changes, and integration data flows in coordination with database owners.
• Design and troubleshoot APIs, file transfers, batch/scheduled interfaces, authentication/SSO integration, and upstream/downstream application interactions.
• Produce concise solution diagrams, interface specifications, technical decisions, implementation notes, and supportable handoff documentation.
• Participate in code and design reviews; improve consistency in error handling, validation, logging, security, maintainability, and performance.
• Work with QA and business analysts to clarify acceptance criteria, provide testable deliverables, correct defects, and meet defined release gates.
• Troubleshoot complex application and production issues involving IIS, SQL Server, integrations, or application logic; coordinate with infrastructure and support teams.
• Design solutions for PVS on-premises Windows/IIS and SQL Server operations, with attention to security, reliability, deployment, support, and rollback.
• Assume increasing responsibility for bounded architecture and delivery decisions under the Lead Developer/Architect; mentor peers through technical collaboration without direct personnel management.

Requirements

• Bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related field, or equivalent practical experience.
• Six or more years of progressive hands-on enterprise software development experience, including involvement in application design and technical problem solving.
• Strong experience with Microsoft .NET, ASP.NET, and Microsoft SQL Server; ability to work effectively with existing VB.NET/.NET Framework applications.
• Demonstrated hands‑on experience developing and maintaining production C#/.NET applications; ability to support and enhance existing VB.NET/.NET Framework applications.
• Experience designing, implementing, and troubleshooting SQL‑backed web applications, APIs, interfaces, and cross‑system data flows.
• Practical application of object‑oriented design, secure development, code review, testing, diagnostics, and maintainable implementation patterns.
• Ability to communicate design trade‑offs, estimate work, document decisions, and collaborate closely with developers, QA, BAs, and infrastructure teams.
• Willingness to remain hands‑on while developing broader architecture responsibilities within an established technical leadership structure.

Preferred Qualifications

• Experience with modern .NET, Blazor Server, incremental legacy modernization, and application migration using coexistence or strangler patterns.
• Familiarity with IIS, Windows Server, SQL Server performance, enterprise authentication/authorization, and on‑premises application deployments.
• Experience with Azure DevOps Server, work‑item tracking, source control, and disciplined development‑to‑test‑to‑production promotion.
• Exposure to operationally critical integrations, scheduled processes, and multi‑client line‑of‑business systems.

Core Competencies

• Hands‑on engineering skill and sound technical design judgment
• Ownership, dependability, and thoughtful escalation of risks
• Ability to complement and extend the Lead Developer/Architect
• Practical modernization within real‑world legacy constraints
• Clear documentation, mentoring, and cross‑functional collaboration
