Application Architect –.NET | Phoenix, AZ (Onsite)
A well-established professional services organization headquartered in Phoenix is hiring a full-time Application Architect to support continued growth and long-term technology modernization. This role sits within a newly formed technology group and works heavily with a Microsoft-based stack including .NET Core, C#, WinForms, SQL Server, and internal enterprise systems. This is a full-time, permanent position requiring five days onsite. This is a rare opportunity to step into an environment where the systems already run the business—but need thoughtful evolution, not a full rewrite. The organization is intentionally building a real technology strategy for the first time and is looking for someone who can balance pragmatism with modernization. The right person will immerse themselves in the current ecosystem, establish standards, mentor developers, and help leadership make informed technical decisions that align with business goals.

- Experience maintaining and improving existing systems (not greenfield-only)
Desired Skills & Experience
- Experience with OAuth or Identity Server implementations
- SSRS or reporting platform experience
- Document generation or document automation experience
- Exposure to AI-assisted development tools (Claude, Copilot, similar)
- Background in legal, mortgage, or financial services environments
- Agile or iterative development experience
What You Will Be Doing
- Maintaining and evolving a large, business-critical application ecosystem
- Defining application architecture standards and best practices
