Company: findev
Location: Poland / Cyprus / Georgia / Serbia / Spain / Armenia / Portugal
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 (Java)

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 (10+years)
▫️Participation in modernization / tech transformation / legacy shift / migration to cloud / migration from legacy / tech upgrade / lift and shift / dockerization is a must
▫️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
▫️Broad infrastructure knowledge
▫️Working knowledge of enterprise middleware and data infrastructure
▫️Open to AI-assisted workflows— we use Agentic AI and LLM tools daily as primary instruments
▫️Enterprise comfort— you've worked in large organizations with large-scale existing systems, change management, and compliance requirements; none of this is new to you
▫️Excellent written and spoken English
▫️Bachelor's or Master's degree in Computer Science, Software Engineering, or a related technical field

Big Plus
▫️Experience with additional JVM or non-JVM backend stacks (.NET, Python, C++)
▫️Experience with AI/LLM tools specifically for code analysis, migration, or large-scale refactoring
Financial services, capital markets, or fintech background — our clients operate in regulated environments with algo trading, post-trade processing, and real-time risk systems
▫️Kubernetes deployment experience (EKS, Helm, ArgoCD)
▫️Cloud migration patterns (lift-and-shift, strangler fig, blue-green, database migration strategies)
▫️ServiceNow, Confluence, Jira fluency — the enterprise tooling ecosystem

Why This Role
▫️Build the practice from scratch
▫️AI-first engineering
▫️Real engineering challenges
▫️High autonomy
▫️Top-tier clients
▫️Modern target platforms

▫️Flexible work setup: remote model (Poland, Cyprus, Serbia, Georgia, Spain, Portugal, Armenia) or hybrid if desired
