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.

Responsibilities

• Design and develop new features for a production trading platform.
• Work directly with traders and business stakeholders to understand requirements and translate them into technical solutions.
• Contribute to the migration of a legacy P&L system into the trading platform.
• Write and maintain production-quality Java code.
• Participate in code reviews and help maintain engineering standards.
• Investigate and resolve bugs and production issues.
• Collaborate with other engineers across the trading platform team.
• 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.

Nice to Have

Experience in the financial services, commodities, or energy trading domain is highly valued, particularly with:

• Trading platforms or ETRM systems
• P&L or risk systems
• Order or execution platforms
• Futures and positions
• Market data
• Trader-facing applications

Additional experience with AWS and cloud-based/containerized deployments is also preferred.

• 100% Remote.
• Paid Time Off: 12 PTO days per year.
