Director - Program & Delivery Management

Job Description Director, Program and Delivery Management Product Operations · London, UK

ABOUT MIMECAST

Mimecast is a leading cybersecurity company protecting people, data, and communications from today’s most sophisticated threats. With over 42,000 customers worldwide and 18 billion security events analyzed daily, we pioneer Human Risk Management – combining threat detection, awareness training, and insider risk management into a platform built around the human element of cybersecurity.

ABOUT THE ROLE

The Director, Program and Delivery Management leads the team responsible for how Mimecast’s Product and R&D organization plans, executes, and delivers – from the first articulation of a program’s goals through to customer impact. You will own the discipline of program and delivery management across the organization: setting the standards, systems, and operating model that enable teams to commit with confidence and deliver with consistency. This function has a strong foundation and is actively evolving. The person who succeeds here combines operational depth with strategic clarity, thrives in ambiguity, and knows how to move an organization without relying on authority.

WHAT YOU’LL DO

Team Leadership & Capability Development

Lead, develop, and retain a team of Program and Delivery Managers, each embedded as a senior partner to Product and R&D leadership across the portfolio. Set the standard for what great looks like – planning ownership, delivery partnership, systemic problem-solving – and coach your team to perform consistently at that level. Monitor team health – pace, process overhead, retention risk – and address emerging issues before they affect delivery or people; champion lightweight processes and actively retire ceremony that has become overhead without value. Partner with leadership to evolve the function as Mimecast scales, ensuring the team’s structure, scope, and skills stay ahead of the organization’s needs.

Planning System & Portfolio Oversight

Partner with senior leadership to shape and evolve the planning system – the frameworks, cadences, and standards that govern how work gets prioritized, resourced, sequenced, and committed to across the portfolio. Maintain a portfolio-level view of commitments, capacity, and delivery confidence – giving leadership a reliable picture of what is planned, what is at risk, and what is on track. Act as the escalation point for cross-portfolio dependencies, trade-offs, and resourcing conflicts – bringing recommended solutions, not just problem statements.

Delivery Rhythm & Execution Governance

Work with leadership to define and maintain the delivery operating rhythm – the cadences, forums, and reporting structures that keep execution visible without adding unnecessary overhead. Ensure your team runs consistent program reviews, proactively manages risk and dependencies, and drives blockers to resolution before they affect commitments. Build and maintain the governance model that drives accountability – visible priorities, clear owners, and timely escalation when delivery is at risk. Ensure programs are managed through their full arc – from requirements gathering and technical design through to customer-facing delivery – with cross-functional dependencies visible and handoffs clearly owned.

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.

WHY MIMECAST

You will be visible at every level of the company as a result. If you want to lead a team doing meaningful work, operate with real influence, and leave a mark on how a world‑class cybersecurity company runs, this is the role.
