Job description

Job Description

At TJX Companies, every day brings new opportunities for growth, exploration, and achievement. You’ll be part of our vibrant team that embraces diversity, fosters collaboration, and prioritizes your development. Whether you’re working in our four global Home Offices, Distribution Centers or Retail Stores—TJ Maxx, Marshalls, Homegoods, Homesense, Sierra, Winners, and TK Maxx, you’ll find abundant opportunities to learn, thrive, and make an impact. Come join our TJX family—a Fortune 100 company and the world’s leading off-price retailer.

About TJX

TJX is a Fortune 100 global retailer powering millions of daily transactions across thousands of stores. At TJX India in Hyderabad, you will join a high‑performance engineering hub modernizing mission‑critical legacy systems into resilient, observable, cloud‑ready architectures. We offer a culture centered on engineering excellence, autonomy, and long‑term career growth.

What You Will Discover

• A modernization‑focused engineering culture valuing deep technical mastery and architectural influence
• A global organization collaborating across the U.S., Canada, Europe, and Australia
• Opportunities to shape core patterns for one of TJX’s most strategic modernization programs
• A highly collaborative environment where senior engineers drive meaningful technical decisions

Our Organization

As a Senior Java / Liberty Modernization Engineer, you will lead the technical dissection and transformation of legacy Azul‑based Java systems running on IBM Liberty. You will define seams, design anti‑corruption layers, and architect incremental extraction strategies that enable zero‑downtime modernization using the Strangler‑Fig pattern. This role is deeply technical and highly influential—while you have no direct reports, your modernization patterns, debugging expertise, and architectural guidance will shape enterprise transformation across teams.

What You Will Do

• Reverse‑engineer complex legacy Java systems to map modules, integration points, and modernization seams.
• Architect and implement compatibility layers, protocol adapters, and anti‑corruption boundaries enabling incremental migration.
• Stabilize legacy systems during transition through JVM tuning, thread/connection optimization, profiling, and caching strategies.
• Design and validate seam extractions aligned with evolutionary architecture and safe rollout sequencing.
• Partner with .NET, platform, and integration teams to define data contracts, transformation rules, and coexistence models.
• Establish automated regression, contract‑testing, and boundary‑validation frameworks that ensure zero‑regression cutovers.
• Debug complex runtime failures across distributed systems, Liberty runtime internals, and tightly coupled legacy modules.
• Create modernization runbooks, architectural patterns, and reference implementations for cross‑team adoption.
• Serve as a technical unblocker—diving into code, pipelines, observability tooling, and system internals to accelerate team velocity.
• Promote engineering excellence through secure coding, CI/CD governance, observability maturity, and measurable reliability improvements.

Minimum Qualifications

• 7+ years of Java engineering experience across enterprise or distributed systems.
• Hands‑on expertise with IBM Liberty, WebSphere, or similar enterprise Java runtimes.
• Proven experience modernizing legacy systems using Strangler‑Fig or incremental‑migration patterns.
• Deep debugging skills across JVM internals, multi‑threaded services, and complex dependency chains.
• Track record delivering stable, highly available, production‑critical services with strong operational rigor.

Preferred Qualifications

• Experience with Azure modernization, containerization, or cloud migration programs.
• Background in retail/store systems, transactional workflows, or distributed integration patterns.
• Expertise in JVM performance tuning, protocol bridging, or event‑driven modernization patterns.
