Senior ETRM Developer – Endur (JVS / OpenComponents)

You'll be joining one of the most technically forward-thinking ETRM teams in the industry – driving design and delivery of a highly integrated Endur platform across front-to-back energy trading functions.

• 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)
• Hands-on Java engineering skills - .Net or C# are transferable
• 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
• Independent mindset – someone who can own delivery and get it done
