Are you a master scheduler who has conquered the complexities of the energy, aerospace, or large-scale engineering sectors? Are you ready to trade terrestrial challenges for celestial ones?

Octagon Professionals, in partnership with the European Space Agency (ESA), is seeking an elite Scheduler to play a mission-critical role in shaping the future of space exploration from theECSAT facilities in Harwell, UK.

This isn't just another project; it's an opportunity to apply your deep expertise in complex planning, scheduling, and risk analysis to some of humanity's most ambitious space missions. We are looking for the strategic mind that can navigate the intricate timelines of flagship scientific and transportation programs, ensuring Europe's access to and exploration of space remains on track.

Your Mission:

As a Principal Scheduler, you will be the authority on all schedule management activities, from initial study phases to mission closeout. You will provide the expert analysis that underpins critical decisions, ensuring these multi-year, technologically advanced projects are delivered successfully.

Your core responsibilities will include:

• Developing, controlling, and maintaining the Mission Baseline Schedules for ESA’s Science and Space Transportation directorate projects.
• Performing complex schedule analysis, including critical path methodology (CPM), trend analysis, and float summary on a vast portfolio of schedules from industrial partners and stakeholders.
• Running sophisticated "what-if" scenarios and schedule simulations to proactively identify risks and recommend mitigation strategies to mission management.
• Mastering the risk-adjusted schedule by utilizing Monte Carlo techniques and tools (such as Deltek Acumen) to provide a realistic forecast of project timelines.
• Serving as the subject matter expert during major technical reviews and procurement activities, evaluating contractor schedules for robustness, logic, and achievability.
• Contributing to the continuous improvement of ESA's business processes, tools, and best practices in the domain of schedule management and control.

• A required Master’s degree in a STEM field.
• A minimum of 4 years of relevant work experience is required.
• Demonstrated master-level expertise in project scheduling, planning, and control within the space/aerospace. Oil and gas, or other major technical engineering industries are a bonus.
• Mastery of scheduling software like Microsoft Project Professional and schedule risk analysis tools using Monte Carlo techniques (e.g., Deltek Acumen) is essential.
• An exceptional communicator, capable of translating complex schedule data into clear, actionable insights for diverse international teams.
• You possess a forward-thinking, proactive, and independent mindset, perfectly aligning with our core values at Octagon.
