AI Integration & Program Management Innovation

• Define the AI strategy for program and delivery management – identifying where AI tools can meaningfully improve how programs are planned, tracked, and delivered, and translating that into an actionable roadmap.
• Keep the team current with evolving AI tools – fostering shared learning and experimentation so best practices spread and the team’s AI fluency grows together.
• Proactively identify opportunities to leverage AI within the teams and programs you support – reducing manual overhead and increasing velocity in the way we manage delivery.

Metrics, Velocity & Reporting

• Own the metrics strategy – defining what gets measured, how, and how delivery-flow data drives decisions at every level.
• Build and maintain executive-facing reporting that gives leadership a clear, honest view of portfolio health: what is on track, what is at risk, and what requires a decision – tailored for both technical and executive audiences.

Pattern Recognition & Systemic Improvement

• Look across the portfolio to identify patterns of friction, misalignment, and inefficiency – and drive improvement programs that address root causes, not symptoms.
• Lead the evolution of shared delivery practices – planning standards, estimation norms, definitions of done – making what works repeatable and retiring what does not.

What You’ll Bring

You have built and led high-performing program management teams in complex, fast-moving product organizations. You know how to design systems that make delivery predictable – and how to drive change in organizations that aren’t yet ready for it.

• 7+ years in Technical Program Management, Delivery Management, or Engineering Program Management, including 4+ years leading a team of program managers within a multi-team Product and R&D organization.
• A track record of designing and owning planning and delivery systems at scale – accountable for the quality and reliability of the output, not just the facilitation of the process.
• Executive presence and communication range – equally effective in a technical dependency conversation with an engineering lead and a portfolio risk briefing with the CPTO; able to influence without authority across functions and levels.
• Proven ability to drive change in complex, matrixed organizations – building alignment around new ways of working, even when it requires pushing against resistance.
• The strategic clarity to see across a portfolio and the operational depth to get into the detail when it matters – and the judgment to know when each is required.
• The analytical capability to build a metrics framework, interpret delivery-flow data, and construct a clear narrative that drives leadership decisions.
• Fluency in agile delivery practices and hands-on experience with delivery tooling (Jira, Confluence, or equivalents); experience leading program managers across multiple geographies and time zones.
• A genuine interest in how AI tools are reshaping program and delivery management, and the drive to lead adoption where it creates measurable value for the team.
• High ownership and a team-first mindset – you bring problems with proposed solutions, develop others to do the same, and measure yourself by what the team achieves.
