Project description

We are DXC Luxoft Financial Services - an award-winning provider of technology solutions, dedicated to the Financial Services sector.

Join our international team and become a member of our open minded, progressive and professional team of financial services consultants. In this role you will be working on projects for biggest investment banks across the globe. You will have a chance to grow your technical and soft skills, and build a thorough expertise in the Capital Markets industry. On top of attractive salary and benefits package, we will invest into your professional training, and allow you to grow your professional career.

Responsibilities

This initiative focuses on:

Upgrading legacy applications to modern Spring Boot versions (2.x 3.x)

Decommissioning and replacing Hazelcast across distributed systems

Refactoring applications to align with modern, cloud-ready, stateless architectures

Enhancing integration with event-driven systems using Apache Kafka

Supporting applications connected to Murex batch and real-time processing flows

This is a high-impact program in a low-latency financial environment, where system stability, performance, and correctness are critical.

We are seeking a Java developer who can design and build with minimum supervision solutions for our team. The person needs to be knowledgeable on modern software development practices including Scrums, be up to date with the latest Java tools and frameworks and be able to work with the existing team to deliver solutions. The ideal candidate will be diligent, tenacious and delivery focused with a track record of building high quality solutions that are resilient and maintainable. Use of cloud technology is increasing, so experience working with AWS would be beneficial.

Design and implement solutions for:

Spring Boot & Hazelcast upgrades (including major version transitions)

Analyze existing distributed system usage (caching, clustering, locking)

Refactor applications toward stateless, scalable microservices

Implement and optimize integrations using Kafka-based event-driven architecture

Collaborate with QA, DevOps, and architecture teams on migration and rollout strategy

Ensure high standards of performance, resilience, and fault tolerance

Participate in code reviews, technical design discussions, and production support

Post-project opportunity:

Following successful delivery of this modernization initiative, team members are planned to be reassigned to other strategic programs within the client’s long-term roadmap, offering continued growth and exposure to new initiatives.
