Original job description

Senior Software Engineer – Application Modernization & AI-Assisted Development Location: Nashville, TN (Hybrid Onsite) Employment Type: 12+ Month Contract Compensation: $65/hr (W2)

About the Opportunity Vaco is partnering with an established enterprise organization seeking a hands-on Senior Software Engineer to modernize business-critical applications and systems. This is a good fit for an engineer who enjoys digging into complex systems, figuring out how legacy applications work, and rebuilding them with modern architecture, scalable technologies, and AI-assisted development tools. We're not looking for someone who simply maintains existing applications or delegates the development work. We need someone who still enjoys getting into the code, solving difficult problems, and owning modernization efforts from concept through production. What You'll Do

Analyze, reverse-engineer, and modernize legacy applications and backend systems
Own modernization initiatives from technical assessment and architecture through hands-on development and deployment
Design and build scalable backend services, APIs, data-processing workflows, and integrations
Evaluate existing technology and determine the right modernization approach rather than defaulting to one programming language
Use AI-assisted development tools to speed up coding, refactoring, testing, troubleshooting, and documentation
Improve application performance, reliability, maintainability, and scalability
Collaborate with engineering teams to align modernized applications with broader technology standards
Take increasing technical ownership as applications and systems are modernized

What We're Looking For

8+ years of professional software engineering experience, ideally building or modernizing enterprise applications
Strong object-oriented programming fundamentals with experience in C#, Python
Strong backend engineering experience involving APIs, integrations, data processing, and application architecture
Experience working with legacy codebases and improving, refactoring, or rebuilding existing systems
Practical experience with AI development tools such as GitHub Copilot, Cursor, Claude Code, or similar tools
Experience with Azure or AWS and scalable cloud application design
Ability to independently assess technical problems, recommend an approach, and execute it
Strong problem-solving skills and a willingness to challenge outdated approaches

By submitting to this position, you are agreeing to be included in our talent pool for future hiring for similarly qualified positions.
