Main Purpose Trafigura is seeking an Optimization Engineer to join its Refining Technical team in Houston, reporting to the Refining Technical Manager. This is a hybrid technical-commercial role split roughly evenly between (i) day-to-day optimization and optionality analysis on Trafigura's splitter asset, and (ii) commercial support to M&A activity, with a particular focus on the Power business — including technical due diligence, HSEC assessment, and commercial evaluation of prospective asset acquisitions. This role is well suited to a process/project engineer with early-career power and/or oil asset experience, looking to transition into a more commercially oriented career path, working closely with trading, business development, and third-party counterparties. Key Responsibilities Splitter Asset Optimization (approx. 50%) Run and maintain LP-based optimization models for the splitter asset to identify margin-maximizing feed selection, product yields, and operating configurations. Evaluate operational and structural optionality on the asset — including feedstock flexibility, product placement, and configuration changes — and quantify the associated commercial value. Work closely with the Refining Technical Manager and plant operations to translate technical constraints (unit capacity, feed quality, operating limits) into actionable optimization inputs. Provide regular margin capture, yield, and sensitivity analysis to support trading and planning decisions on the asset. Identify and evaluate capital or operational improvement opportunities that enhance asset value. Commercial / M&A and Power Business Support (approx. 50%) Support M&A activity across the business, with a focus on both the Oil & Power business, including screening, evaluating, and progressing prospective asset acquisitions. Lead or contribute to technical due diligence on power and other prospective assets — assessing technical condition, operating performance, and integration/optionality potential. Conduct HSEC
