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.

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.

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.

Nice To Have

Experience with GIS technologies such as ESRI MapObjects or ArcSDE.
Familiarity with CI/CD tools like Jenkins or GitHub Actions.
Python scripting for automation, tooling, or system integration.
Prior experience in legacy-to-modern system migration projects.
Exposure to cloud or distributed system modernization initiatives.

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.
