Senior Software Engineer (VB6 / Legacy Modernization)

Senior Software Engineer (VB6 / Legacy Modernization)

You will join a high-impact engineering environment focused on modernizing large-scale, mission-critical government software used across hundreds of municipalities in the United States. In this role, you will work directly with a complex VB6 legacy system that remains essential to daily public sector operations, contributing to its gradual evolution toward modern architectures. Your work will combine deep legacy code understanding with hands-on development in Python and SQL, supported by AI-assisted engineering workflows. You will collaborate closely with distributed engineering teams, helping to improve system reliability, performance, and maintainability. The role requires strong problem-solving skills in production environments and the ability to navigate complex, long-lived codebases. This is a unique opportunity to work on meaningful modernization challenges in a fully remote, international engineering setup.

Accountabilities:

• Maintain, analyze, and incrementally modernize a large VB6 legacy codebase supporting government operations.
• Use AI tools to understand, document, and refactor complex legacy systems.
• Develop new features and services using Python and SQL alongside existing system components.
• Diagnose and resolve production issues in multi-tenant, mission-critical environments.
• Work with relational databases, optimizing queries and supporting scalable data models in SQL Server.
• Collaborate with engineering teams to ensure smooth integration between legacy and modern components.
• Support incremental migration strategies from legacy technologies to modern architectures.
• Contribute to system reliability, debugging, and performance improvements across the platform.
• Participate in code reviews, technical discussions, and architecture evolution initiatives.
• Leverage AI-powered development tools as part of daily engineering workflows.

Requirements:

• Strong experience working with large and complex legacy codebases.
• Solid proficiency in SQL Server and relational database design.
• Ability to read, understand, and maintain legacy technologies such as VB6 and COM/ActiveX.
• Strong debugging skills in production-grade, distributed systems.
• Hands-on experience using AI-assisted development tools (e.g., Copilot, Cursor, Claude Code, or similar).
• Strong analytical thinking and structured problem-solving abilities.
• Experience working in multi-tenant or enterprise-scale environments.
• Ability to work independently in remote, distributed teams.
• Good communication skills and collaborative mindset.

Benefits:

• 100% remote work environment.
• Long-term international projects with stable engagement.
• Compensation in USD.
• Paid time off (PTO).
• English lessons and continuous learning support.
• Technical training and professional development opportunities.
• Home office (WFH) budget support.
• Career coaching and growth support.
• Opportunity to work on impactful public sector modernization projects.
• Collaborative engineering culture with direct product and technical ownership.
