The Role

We are looking for an experienced Java Software Engineer to join Fasanara Digital and take significant ownership of systems supporting our 24/7 trading activity.

• Design reference data frameworks and accounting pipelines supporting both traditional financial instruments and digital assets.
• Develop primarily in Java and Kotlin, contributing to architecture and technical design while remaining highly hands-on.
• Maintain, refactor, and improve existing production code alongside developing new functionality.
• Take end-to-end ownership of technical problems, from design through to production delivery and ongoing support.
• Work closely with engineers and investment stakeholders to translate business requirements into effective technical solutions.
• Use modern AI-assisted development tools to improve engineering productivity and software quality.
