Why This Role Matters

We are seeking an experienced Senior Project Manager to independently lead and drive complex, cross-functional projects across the organisation. As part of the central PMO office, this role is essential in ensuring the successful delivery of high-priority strategic and operational initiatives spanning multiple business domains: from product development and engineering transformation to enterprise-wide operational programmes.

Working closely with senior stakeholders across Product, Engineering, Operations, and Business functions, the Senior Project Manager will be a trusted advisor and influential leader, driving projects with a high degree of autonomy, providing consultative guidance on methodology and resourcing, and helping to shape the way the PMO operates and grows.

Your Key Responsibilities

Project Planning & Execution

• Define project scope, objectives, and deliverables in alignment with the business project sponsor and senior stakeholders.
• Independently develop and maintain comprehensive project plans, timelines, and roadmaps for complex, cross-functional initiatives.
• Drive projects autonomously in critical phases, proactively managing risks and resolving issues to ensure timely delivery.
• Track and report on key project milestones, status, risks, and budget considerations, providing clear visibility to all stakeholders.
• Select, combine, and tailor project delivery approaches (Agile, Scrum, Waterfall, hybrid) to best fit the needs of each initiative.
• Lead project retrospectives, capture lessons learned, and drive continuous improvement across the project lifecycle.

Stakeholder Management & Senior Relationship Building

• Build strong, trusted relationships with senior stakeholders across different departments, establishing non-formal authority through credibility and consistent delivery.
• Navigate and resolve conflicts between stakeholders with competing interests, facilitating alignment and consensus on complex issues.
• Craft and deliver persuasive, clearly structured communications to gain buy-in from functional leads and business leadership.
• Act as a trusted advisor to project sponsors: proactively flagging risks, shaping decisions, and managing expectations at all levels of the organisation.
• Adapt communication style and depth to suit diverse audiences, from project team members to senior leadership.

Business Impact & Strategic Alignment

• Assess project impact on the overall business and evaluate trade-off decisions in terms of broader business benefits and risks, not just project-level constraints.
• Proactively identify strategic dependencies, opportunities, and risks across assigned initiatives.
• Clearly articulate project purpose, business rationale, and value to the team, stakeholders, and leadership.
• Recommend and influence decisions that protect or enhance the business case of assigned initiatives, ensuring projects remain aligned with organisational goals.

Process, Governance & PMO Contribution

• Align project execution with the company's governance framework, ensuring compliance with PMO standards, tools, and processes.
• Lead improvements within assigned projects and actively take ownership of selected PMO assets (templates, playbooks, standards).
• Actively contribute to PMO organisation building, participating in initiatives that improve team-wide delivery quality and consistency.
• Provide guidance and informal mentoring to less experienced Project Managers on the team.
• Proactively share best practices, lessons learned, and methodological insights with the wider PMO team.

What You'll Bring

Required:

• 5+ years of experience in project management, with a proven track record of independently leading complex, cross-functional projects in a fast-paced, matrixed environment.

• Proven experience managing projects without direct authority, leveraging stakeholder engagement, influence, and non-formal leadership.
• Strong ability to assess project trade-offs in terms of broader business impact, going beyond project-level constraints to deliver genuine business value.
• Exceptional communication and interpersonal skills: able to deliver complex ideas clearly and concisely, resolve conflicts constructively, and build trusted relationships with senior stakeholders.
• Demonstrated ability to drive projects autonomously in critical phases, providing consultative guidance to project teams on methodology, tools, and resourcing.
• Proficiency with project management tools (e.g., Jira, Confluence, MS Project, Monday.com).

Experience We Consider a Plus:

• A proven track record of successfully delivering complex, cross-functional projects with clear business impact, across a range of project types and business domains.
• Demonstrated expertise in stakeholder management, conflict resolution, and working effectively in a matrixed organisation.
• Strong leadership and communication skills to guide cross-functional teams and influence decisions without formal authority.
• A collaborative mindset and genuine commitment to contributing to team growth: sharing knowledge, improving processes, and helping develop others.
