- Solid understanding of the trade lifecycle, strong technical troubleshooting, and the ability to interface with front-office users.

- Driving platform enhancements and new builds across STP, PnL, and risk.
- Managing technical support and resolving live incidents (hands-on).
- Leading discussions with the business and on/offshore teams.
- Building and supporting custom web interfaces, APIs, and backend integrations.
What you’ll need:
- Expert-level Endur experience – JVS or OpenComponents (Java).
- Strong SQL / Oracle skills.
- Familiar with key tech: REST APIs, Kafka, DMS, Crystal Reports, Tomcat.
- A good grasp of the ETRM lifecycle: Trading, Risk, Ops.
- Bonus points for Python skills and experience building WebApps.
