A little more about your role… We’re excited to be growing our Environmental Project Management team and are looking for several Assistant Project Managers to join us in our PMO team. In this role, you’ll play a key part in supporting the delivery of multi-disciplinary environmental projects, working closely with Project Managers and Technical Leads to keep projects safe, on track and within budget.

It’s a brilliant opportunity to build your core project management foundations, learning how to apply structured processes and best practice in a real project environment.

• Supporting the development of project proposals, helping to define scope, programme, resources and budget
• Assisting with key project management documentation, including plans, cost forecasts, schedules, risk registers and stakeholder logs
• Coordinating project progress, helping track delivery against milestones
• Ensuring health and safety requirements for site visits are in place, including approvals
• Organising meetings, capturing key outcomes and following up on actions
• Managing project information within Common Data Environments such as SharePoint and ProjectWise
• Working as part of multidisciplinary teams, collaborating with technical specialists and suppliers

• Experience supporting project or workstream delivery, with an understanding of how to keep activities aligned to time, cost and quality expectations.
• Comfortable working with project documentation such as plans, schedules, risk logs, budgets and reports.
• High attention to detail, with the ability to work accurately with data and identify inconsistencies or issues early.
• Able to organise and prioritise your workload across multiple tasks or projects.
• Confident using Microsoft Office, particularly Excel, to manage, analyse and track information.
