As a Senior Software Developer, you will work extensively with an established Visual FoxPro-based application environment, supporting existing functionality while developing enhancements, resolving technical issues, and helping move our products forward.

The ideal candidate is someone who is comfortable working in a legacy technology environment and understands that maintaining mature software requires more than simply writing new code. You will need to be able to understand existing architecture and business logic, troubleshoot issues, identify root causes, and make thoughtful changes without disrupting critical functionality.

This role may also provide opportunities to participate in modernization efforts, integrations, database development, and the gradual evolution of our technology platform.

• Assist with integrations between legacy applications and newer technologies.
• Participate in efforts to modernize and improve existing applications and development processes.
• Develop a strong understanding of the business processes supported by our software, particularly financial, accounting, billing, and utility operations.

What We're Looking For

Required:

• 5+ years of professional software development experience.
• Professional experience developing or maintainingVisual FoxPro (VFP) applications.
• Strong understanding of relational databases, DBF structured files,and SQL.
• Experience troubleshooting and debugging complex applications.
• Ability to work independently within a large, established codebase.
• Strong analytical and problem-solving skills.
• Ability to understand and work with existing code rather than relying exclusively on greenfield development.
• Strong communication skills and the ability to work effectively with both technical and non-technical team members.

Preferred:

• Experience with Microsoft SQL Server.
• Experience with C#, .NET, APIs, or other modern development technologies.
• Experience integrating legacy applications with newer systems.
• Experience modernizing or migrating legacy applications.
• Experience with financial, accounting, ERP, billing, or utility billing software.
• Experience developing software used by local governments or utilities.
• Experience working in a SaaS or enterprise software environment.
• Experience with AI tools such as Claude or Codex.

What Success Looks Like

In this role, success means becoming a trusted technical resource for our existing applications and the team that supports them. You will be able to navigate a complex legacy codebase, understand how changes affect the broader system, resolve issues efficiently, and deliver reliable enhancements for our customers.

Over time, you'll also have the opportunity to contribute to the evolution and modernization of our technology platform.

Why Join Black Mountain Software?

• Work on software that supports essential financial and operational functions for local governments and utilities.

• Join an experienced team with deep knowledge of the products and the customers who rely on them.
