Web App Developer Jobs in Michigan (NOW HIRING)

Wolverine Solutions Group is a full-service direct mail production and document management company serving over 120 clients in local and national markets. Over the last several years we have built a proprietary, decoupled platform that has transformed our business: client onboarding that used to take days or weeks now takes a few hours, and roughly 90% of our workflow is configurable without writing code.

We are looking for a Software Developer II to help support and grow that platform. Today it includes 250+ web parts, 100+ business reports (accounting, inventory, production), and the customizable layers that matter most to our clients: ETL, postal normalization (BCC), and document composition. The remaining workflow - SFTP ingestion, decryption, job folder creation, data retention, internal and external dashboards - is fully automated and template-driven.

This role is roughly 30% maintaining and improving what we have, and 70% building new - onboarding new clients, extending the platform, and contributing to a gradual migration from .NET Framework to .NET Core/8.

• Build and maintain ETL routines that ingest, normalize, and stage client data files for production.
• Develop and extend internal C#/.NET web applications, web parts, and business reports.
• Configure and customize composition workflows and BCC postal presort jobs from existing templates.
• Gather requirements directly from internal stakeholders (production, customer service, accounting) and occasionally from clients - then make decisions and ship.
• Triage and root-cause production issues across the platform.
• Contribute to the ongoing migration from .NET Framework to .NET Core/8 as the codebase evolves.
• Identify performance bottlenecks and design for future scalability.

Primary: C#, .NET Framework (~95%), SQL Server, ASP.NET MVC

Growing: .NET Core / .NET 8 (~5% today, expanding over time)

Reporting: Crystal Reports, SSRS

Domain tooling: BCC postal software, document composition engines, SFTP/PGP, internal dashboards

Legacy (occasional): VB.NET

• Strong proficiency in C# and SQL Server - you write clean, performant code and queries.
• Solid experience with .NET Framework and ASP.NET MVC; familiarity with .NET Core/8 is a plus.
• Comfortable building reports in Crystal Reports, SSRS, or similar.
• Understands when to use which architecture (web app vs. web service vs. console job vs. scheduled task).
• Strong debugging instincts and ability to read and support unfamiliar code.

• Can gather requirements from non-technical stakeholders and translate them into working software - without waiting for a perfect spec.
• Pragmatic decision-maker: comfortable making the call, shipping, and iterating.
• Composed under pressure - you can tell the difference between a real problem and manufactured chaos, and you don't get pulled into the latter.
• Self-directed, but knows when to pull others in.
• Cares about the platform working well for the people who depend on it.

• Experience in print, mail, manufacturing, or other production-driven environments.
• Familiarity with postal presort, IMb, NCOA, or document composition tools.
• Experience modernizing legacy .NET Framework codebases to .NET Core/8.
• Exposure to SFTP automation, PGP encryption, or file-based integration patterns.

Bachelor's degree in Computer Science or a related field perferred, OR equivalent professional experience. Typically 5+ years of professional .NET development experience, but we care more about what you can do than the number on a resume.
