Employment: fulltime Payment: from 6000 USD gross up to 8000 USD gross (depends on the location, negotiable - only mentioned locations) Position: Senior Software Engineer — App Modernization

We're building an AI-powered application modernization practice for major global financial institutions. The work: take legacy enterprise applications — monoliths, on-prem deployments, decade-old frameworks — and move them to modern platforms (Kubernetes, cloud-native, containerized). Hundreds of applications, each with its own stack, quirks, and business constraints. Most happen to be Java, but not all.

What You Will Do

• Assess legacy applications end-to-end: architecture, dependencies, infrastructure, risk — using AI-assisted analysis tools
• Decide migration strategy for each app based on its characteristics, constraints, and business value
• Execute the full modernization: framework upgrades, dependency migration, containerization, CI/CD pipeline setup
• Deploy to target platforms — cloud services, or optimized on-prem — whatever makes sense for the app
• Shape the modernization practice itself: contribute patterns, templates, and lessons learned that make the next migration faster
• Collaborate with application teams who own the legacy systems

Required

• Strong Java/Spring expertise— the majority of the target portfolio is Java (7+years)
• Hands-on modernization experience— you've migrated enterprise applications from older frameworks, runtimes, or platforms to modern ones. Java is the most common target, but the next app could be anything
