Senior Java Engineer/Architect

Senior Java Engineer/ArchitectLocation: Baltimore, MDJob Type: HybridWe are seeking a Senior Java Engineer/Architect to join our team supporting and modernizing the Vision platform — a critical legacy system at the heart of our fund management operations. Vision is a complex, legacy platform written in a proprietary language similar to Java/J2EE in Unix with deep Object-Oriented and Smalltalk roots. This is not a routine maintenance role.Mandatory Skills·Java /J2EE – Strong, production-grade command of Java (8+), J2EE architecture, and related enterprise patterns. Ability to read, debug, and extend mature codebases.·OOP & Design - Deep understanding of Object-Oriented principles — encapsulation, inheritance, polymorphism, SOLID principles, and design patterns (GoF). Ability to reason about complex class hierarchies.·Legacy Fluency - Comfort navigating underdocumented legacy systems. Ability to reverse-engineer behavior through code reading, profiling, and test-driven exploration rather than relying on spec docs. Ability to use AI tools to reverse engineer legacy code.·AI Engineering Tools - Good knowledge of AI tools like GitHub Copilot or equivalent, LLMs, MCP servers.·Architecture - Hands-on experience with monolith-to-services decomposition, REST API design, and cloud-ready patterns (AWS or equivalent). Familiar with containerization (Docker/Kubernetes).·Smalltalk /Unix - Working knowledge of Smalltalk — particularly in a J2EE-adjacent context — is a significant advantage. Familiarity with Smalltalk's message-passing model and reflective programming style.·CI/CD & Tools: Proficiency with Git, Maven/Gradle, Jenkins or equivalent pipelines. Experience with SonarQube or similar code quality tools is a plus. Understanding of databases and data models.Candidate Profile·Executive Presence: Confident representing Hexaware in client-facing settings. Able to engage with senior business and technology leaders with clarity and credibility.·Proactive Mindset: Doesn't wait for direction — researches the problem space, formulates options, and comes to the table with a recommendation or prototype.·Cross-Functional Comm.: Equally comfortable in engineering deep-dives and business-facing discussions. Adapts communication style to the audience — from developers to managers.·Intellectual Curiosity: Genuinely interested in understanding how legacy systems work, why they were built the way they were, and what the better path forward looks like. Able to decompose ambiguous problems, form a hypothesis, design a quick experiment (MVP), and iterate. Strong written and verbal articulation of findings.·Ownership & Accountability: Takes end-to-end accountability for assigned workstreams.
