About the Role

We are looking for a Senior Software Engineer to join a Trading Platform team supporting a large financial services organization in the commodities and global markets space.

You will work on a platform used by traders across the oil, gas, and energy trading business. The role combines hands-on software development with close collaboration with front-office teams to understand trading workflows and turn business requirements into production-ready solutions.

A key initiative will be the migration of a legacy profit-and-loss (P&L) system into the core trading platform, followed by the decommissioning of the legacy system. You will also contribute to ongoing feature development, troubleshooting, code reviews, and production support.

This is a hands-on engineering role where strong Java development experience is the top priority.

Use AI development tools such as Claude to support development, troubleshooting, code review, and problem solving.

Qualifications

5+ years of professional software engineering experience.
Strong, hands-on Java expertise — this is the primary technical requirement.
Working experience with Python and SQL databases.
Familiarity with Kubernetes and containerized applications.
Experience using AI tools such as Claude in software development.
Strong experience across the software development lifecycle, including requirements, technical specifications, coding, code reviews, debugging, and releases.
Professional English communication skills and the ability to collaborate directly with US-based engineers and business stakeholders.
