Job Summary:

We're seeking an experienced Java Lead to lead the modernization and migration of legacy

applications to modern Java-based platforms. The ideal candidate will have a strong

technical background, experience with modernization and migration projects, and excellent

problem-solving skills.

Key Responsibilities:

Lead the assessment, analysis, and documentation of existing legacy Java applications to

identify technical debt, performance bottlenecks, and security vulnerabilities.

- Design and champion the future-state cloud-native architecture, including

microservices, containerization (Docker/Kubernetes), and API-first design.

- Evaluate and select the right technology stack for modernization (e.g., Spring Boot,

Quarkus, cloud providers - AWS/Azure/GCP), data migration strategies, and CI/CD

tools.

- Define and enforce coding standards, best practices, and non-functional

requirements (performance, security, reliability).

- Lead by example by writing clean, scalable, and well-tested code for critical

components of the new system.

- Actively participate in the migration process, which may include strategies like

Strangler Fig Pattern, lift-and-shift, or complete rewrite.

- Perform and guide complex code refactoring, database schema modernization, and

API decomposition.

- Own the end-to-end technical delivery of the modernization roadmap.
- Mentor, coach, and grow a team of backend and full-stack engineers, fostering a

culture of technical excellence and continuous learning.

- Manage task allocation, sprint planning, and technical dependencies within an

Agile/Scrum environment.

- Facilitate knowledge sharing sessions on up-to-date Java technologies, cloud patterns,

and migration techniques.

- Collaborate closely with Product Managers, Business Analysts, and other





engineering teams to ensure the modernized platform meets business objectives.

- Communicate complex technical concepts, progress, and risks effectively to both

technical and non-technical stakeholders.

- Work with DevOps/SRE teams to establish robust CI/CD pipelines, monitoring, and

alerting for the new platform

Required Skills:

3+ years of extensive experience in Java development, with a deep understanding of the

JVM, performance tuning, and memory management.

- Proven track record of leading at least one large-scale legacy Java application

modernization, migration, or re-architecture project.

- Expert knowledge of legacy Java technologies (e.g., J2EE, Servlets, JSP, EJB, Struts)

and modern frameworks (Spring Boot, Spring Cloud, Spring Security).

- Strong experience with microservices architecture, REST APIs, and distributed

systems design patterns.

- Hands-on experience with containerization and orchestration (Docker,

Kubernetes) and cloud platforms (AWS, Azure, or GCP).

- Deep understanding of database technologies, both SQL (Oracle, PostgreSQL) and

NoSQL, and migration strategies.

- Mastery of modern software engineering practices: CI/CD (Jenkins, GitLab CI), Git,

Maven/Gradle, and Agile methodologies.

- Excellent problem-solving, communication, and team leadership skills.

Preferred Qualifications (Nice-to-Have)

- Experience with application servers like WebLogic, WebSphere, or JBoss.
- Knowledge of Infrastructure as Code (IaC) using Terraform or CloudFormation.
- Familiarity with reactive programming (Project Reactor) or alternative JVM

languages (Kotlin).

- Experience with domain-driven design (DDD).
- Understanding of security best practices in a microservices environment (OAuth2,

JWT).
