The Project Scheduler is responsible for the development, maintenance, and integrity of project schedules across the company portfolio of deep-sea mineral development projects. Supporting multiple projects simultaneously, this role is the specialist point of accountability for all scheduling activity - from early-stage concept schedules through to detailed execution plans. A critical function of the role is the receipt, review, and integration of contractor-supplied Primavera P6 schedules into company's master project schedules, ensuring a single, coherent view of progress and critical path across all workstreams. The Scheduler works closely with Project Managers and the Project Controls Engineer to ensure schedule data drives meaningful decision-making at every Stage Gate. Responsibilities: Schedule development and maintenance • Develop and maintain fully resource- and logic-linked project schedules in Primavera P6 and MS Project across multiple concurrent capital projects, from pre-FEED through to production • Build schedules from first principles, establishing work breakdown structures (WBS), activity dictionaries, logic sequences, durations, and resource assignments in alignment with the Stage Gate Development Framework • Maintain schedule baselines and manage all updates through a clearly defined schedule update cycle, ensuring version control and audit trail integrity • Identify, monitor, and report the critical path and near-critical paths for each project, flagging risks to key milestones proactively • Develop and maintain summary-level milestone schedules for senior leadership and external stakeholder reporting, alongside detailed working schedules for project teams Contractor schedule integration • Receive, review, and validate P6 schedules submitted by contractors and vendors - assessing logic, resourcing, float, and compliance with company's scheduling standards and contract requirements • Identify schedule anomalies, missing logic, open ends, and unrealistic durations in contractor submissions; prepare formal review comments and track resolution • Integrate contractor P6 schedules into company's master project schedule, maintaining interface logic and ensuring alignment between internal and contractor activities • Manage the schedule interface register, tracking cross-contractor and cross-project dependencies and escalating conflicts to the Project Manager • Participate in contractor progress meetings and schedule review workshops, providing independent schedule analysis and challenging contractor narratives where required Reporting and analysis • Produce weekly and monthly schedule performance reports - including earned value schedule metrics (SPI, SV), float trend analysis, and look-ahead schedules - for Project Managers, the Project Controls Engineer, and VP Project Delivery • Support quantitative schedule risk analysis (QSRA) using Monte Carlo simulation tools (e.g. Primavera Risk Analysis / Oracle Risk), translating outputs into probabilistic completion forecasts • Maintain schedule change logs and support the formal change control process by modelling the schedule impact of proposed scope changes and presenting options to the Project Manager • Contribute to project close-out by capturing as-built schedules and feeding lessons learned into future schedule development • Support the development and continuous improvement of company's scheduling standards, templates, and coding structures as the project portfolio grows Requirements: • 7+ years of dedicated project scheduling experience on major capital projects in the offshore energy, subsea, marine, or mining sectors • Expert-level proficiency in Primavera P6 - including multi-project environments, resource loading, baseline management, schedule coding, and reporting; P6 Professional certification highly regarded • Strong working proficiency in MS Project, including cross-project linking, master schedule consolidation, and stakeholder reporting outputs • Demonstrated experience receiving, auditing, and integrating contractor-supplied P6 schedules into owner master schedules - including identification of logic errors, float manipulation, and non-compliant submissions • Solid understanding of critical path method (CPM) scheduling, earned value management, and schedule risk analysis principles • Experience working across multiple concurrent projects in a portfolio environment, with the ability to prioritise and manage competing schedule demands • Familiarity with quantitative schedule risk analysis (QSRA) tools and methodology - experience with Primavera Risk Analysis or equivalent is advantageous • Strong interpersonal skills - comfortable challenging contractor schedule submissions constructively and presenting schedule data clearly to project teams and leadership • Highly organised and detail-oriented, with a track record of maintaining schedule integrity under project pressure • Relevant degree in engineering, project management, or a related discipline • PMI Planning & Scheduling Professional (PSP) or AACE Planning & Scheduling Professional certification is preferred but not required
