Your very own career expert that helps elevate your application to the next level.
LNG market knowledge is particularly valuable and would be a significant differentiator. Broader commodities or financial trading experience would also be highly relevant.
This role would suit a senior engineer who combines strong technical capability, commercial awareness, and excellent communication skills, and who is comfortable operating directly with the business rather than working solely from predefined specifications.
