Software Engineer — App Modernization
The Project
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.
AI tools (Agentic AI, LLM agents, automated analysis pipelines) are the primary instruments in this workflow. They handle volume — codebase scanning, dependency mapping, migration code generation. But the hard part isn't the code transformation. It's the decisions: what to migrate, where to migrate it, which strategy to use (rehost, replatform, refactor, rebuild), and how to sequence it without breaking production systems that handle real money.
That's where you come in.

What you will do
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
Required
- 7+ yearsin software engineering with progressive seniority
- Backend-first engineer— your strength is server-side systems (APIs, services, data pipelines), but you can read and navigate across layers of the stack when needed
- Strong Java/Spring expertise— the majority of the target portfolio is Java
- 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— you understand the differences between on-prem, cloud, Kubernetes, VMware, and bare metal; deep in some, conversant in all
- Working knowledge of enterprise middleware and data infrastructure— messaging (e.g., Kafka, JMS), relational databases (e.g., Oracle, PostgreSQL), transport protocols (REST, gRPC, SOAP), CI/CD pipelines, and monitoring stacks
- Open to AI-assisted workflows— we use Agentic AI and LLM tools daily as primary instruments; experience with AI-assisted development is a plus, willingness to work this way is required
- Autonomous decision-maker— you can assess a system, form a migration strategy, and defend your recommendation without waiting for someone to tell you what to do
- 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— you'll communicate with technical teams, write documentation, and present migration plans
- Education— Bachelor's or Master's degree in Computer Science, Software Engineering, or a related technical field
Nice to have
Big Plus
- Experience with additional JVM or non-JVM backend stacks (.NET, Python, C++) — several apps in the portfolio use mixed technology
- 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
