Study Manager

**About us** Worley is a global company of energy, chemicals and resources experts headquartered in Australia. We partner with our customers to deliver projects and create value across the life of their assets. We specialize in consulting, engineering, procurement and construction across the project lifecycle, with services extending through to operations and decommissioning. Leveraging extensive experience and AI-enabled delivery, we support customers in navigating complexity as they meet today's needs and transition to more sustainable solutions. **Why Does This Position Exist?** The Study Manager exists to lead Worley studies and small-value engineering projects from Conceptual Engineering, Pre-Front End Engineering Design, Front End Engineering Design and, where required, into Detailed Design. The role is intended for a process-led Chemical Engineer who can define development options, test them technically and economically, recommend the preferred scheme, and develop the selected scheme to the level required for the next project gate. The position is particularly focused on brownfield and existing-facility work, including debottlenecking, capacity improvement, operability improvement, safeguard review, tie-in definition and practical implementation planning. The Study Manager must be able to work directly with senior client management, asset stakeholders, operations teams, technical authorities and internal Worley leadership, and must be able to defend recommendations under intense technical, commercial and governance scrutiny. This is a hands-on leadership role. It is not a purely administrative project coordination role. The role requires strong process engineering judgement, front-end project development experience, commercial awareness, stakeholder confidence, excellent presentation skills and the ability to resolve conflict without losing control of the study outcome. **Priority** **What - How - Why** **Responsibility** **% of total job** 1 **Study and small project delivery** · Plan, lead and deliver small-value Worley studies, small Front End Engineering Design packages, plant modification projects and engineering packages from Conceptual Engineering through Pre-Front End Engineering Design, Front End Engineering Design and selected Detailed Design scope. · Prepare and control the study execution plan, deliverable register, assumptions register, decision register, action tracker, risk register and stakeholder engagement plan. · Coordinate multi-discipline work so that process, safety, layout, mechanical, piping, pipeline, electrical, instrumentation, civil, structural, estimating, planning, procurement, construction, commissioning and start-up inputs are integrated from the outset. · Ensure outputs are sufficiently mature for the agreed project phase, the required estimate class, the next investment or execution gate, and where applicable procurement, shutdown, turnaround, commissioning and start-up planning. Accountable for assigned study / project delivery. Shared responsibility with Project Manager for cost and schedule. Shared responsibility with Engineering Manager for technical assurance. 20% 2 **Conceptual engineering, option identification and debottlenecking** · Lead conceptual engineering for existing facilities, small projects, small Front End Engineering Design packages and plant modifications, including definition of constraints, operating cases, bottlenecks, interfaces, battery limits and technical success criteria. · Identify feasible development, debottlenecking and implementation options using process engineering judgement, site data, operating history, process models, equipment adequacy checks and discipline inputs. · Eliminate non-viable or uneconomic options early, shortlist practical options, and define each shortlisted option to a comparable level of maturity for fair technical and economic evaluation. · Develop the selected scheme to the depth required for Front End Engineering Design and, where required, support transition into Detailed Design, procurement support, construction planning, shutdown execution, commissioning and start-up. Accountable for option development and recommendation quality. Responsible for ensuring decisions are traceable to data, assumptions, calculations and agreed evaluation criteria. 18% 3 **Technical and economic evaluation of options** · Lead structured option evaluation covering safety, operability, constructability, maintainability, capital cost, operating cost, schedule, shutdown and turnaround impact, production value, risk, carbon / energy impact where relevant, procurement constraints, commissioning needs, start-up risk and implementation complexity. · Work with estimators, planners and discipline leads to produce realistic option cost and schedule inputs appropriate to the study phase. · Prepare option selection reports, decision papers and recommendation packs suitable for senior management app
