Our casual professional atmosphere encourages team members to collaborate, innovate and support our operating companies. Our passion and drive advance the reputation of our operating companies and brands—together, we make a difference.

Are you the person who quietly makes everything around you better organized, more polished, and on time?

Are you a creative communicator who can turn a half-formed idea into something polished and ready for an executive audience?

Are you excited by the idea of learning a new domain by sitting next to the leader of it?

If so, we have a unique opportunity to join our Cybersecurity team at Post Holdings, where you will be the operational engine and creative force behind how Cybersecurity shows up across our enterprise, to leadership, to our operating companies, and to every employee whose data we are entrusted to protect.

As a key member of the Corporate Cybersecurity team, you will report directly to the VP, Chief Information Security Officer (CISO) & Chief Privacy Officer (CPO), and work across a broad team that spans Cybersecurity, Privacy, and IT Operations. You will partner across the senior leaders of the team as well as the Cybersecurity and IT leaders embedded in our operating companies and the business unit teams they support. You own your work end-to-end: designing the offsite and calling the venue, drafting the executive memo and proofreading it, planning the Summit and working the run-of-show on the day. The bar is leadership; the muscle is execution.

OBJECTIVE / KEY RESULT AREAS

The Sr. Program Manager is the operational backbone of the enterprise Cybersecurity function and a trusted partner to the VP, CISO & CPO. This is a senior operational leadership role with enterprise-wide scope and end-to-end ownership, combining strategic design with hands-on execution, covering the function's governance, communications, executive reporting, project portfolio, events, and policy lifecycle.

Operating altitude and elevation. This role operates at the enterprise level and routinely coordinates with, and is accountable to, the most senior audiences at Post: the CISO & CPO, the CIO, the Audit Committee and the Board, the senior leaders of the Cybersecurity function (Architecture & Operations, Risk Management, and Privacy & Technology Compliance), the Cybersecurity leaders embedded in each operating company, and IT and business-unit leadership across Post's operating companies

Technical security decisions remain with subject-matter experts on the Cybersecurity team.

RESPONSIBILITIES

Run the Operating Rhythm of the Enterprise.

• Set and run the cadence of Post's enterprise Cybersecurity leadership and governance bodies: the Enterprise Security Council, the Enterprise Security Risk Group, and the Operational Technology Security Council.
• Own the agendas, pre-reads, briefings, tracking of decisions, and follow-ups, ensuring outcomes and action items are documented, communicated to leadership, and driven to closure across the enterprise.
• For the IT Leadership group, own the readouts and reporting into the group; its meeting cadence is owned elsewhere.

Bring Polish to Executive & Board Reporting.

• Partner with subject-matter experts across the Cybersecurity team to collect, curate, and shape the inputs for monthly, quarterly, and ad-hoc reporting packages for the CIO, Audit Committee, Board, and other senior leaders.
• Translate raw program activity into clear, board-ready insight that earns the reader's trust.

Own Cybersecurity Communications & Brand.

• Own the end-to-end communications process across the Cybersecurity and IT Operations organization: intake, design, drafting, review, approval routing, and publication.
• The CISO sets the voice and the message; you operationalize it. Establish the standards, templates, and review gates that ensure every team, including Corporate Cybersecurity, IT Operations, the Cybersecurity and IT leaders embedded in each operating company, and partner functions, communicates in one consistent, on-brand voice to leadership, employees, and external audiences.
• Serve as the editorial gate: review and approve outbound communications for clarity, consistency, and alignment to the CISO's voice before they reach executive, enterprise, or external audiences.
• Own how Cybersecurity shows up across the function. Design and deliver the annual Cybersecurity Summit and the other in-person team meetings and gatherings that bring the Cybersecurity teams together.
• Manage the budget, vendor relationships, and logistics that make these programs run, with a keen eye for how things look and feel

Own the Cybersecurity, Privacy & IT Operations Budget.

• Manage, track, process, forecast, update, monitor, and report on the full Cybersecurity, Privacy, and IT Operations budget, maintaining an accurate, current view of spend against plan across the function.
• Partner with Finance to build and update forecasts, reconcile actuals to plan, and keep budget owners aligned to the numbers throughout the cycle.
• Identify and recommend optimizations, including cost efficiencies, reallocations, and savings opportunities, and surface them to the CISO & CPO and Finance for decision.

Own the Portfolio of Programs.

• Own the single, current picture of what's in flight across a portfolio of programs that spans Cyber Operations, Cyber Risk, Cyber Compliance, Privacy, IT Workforce Productivity, IT Operations, and IT Service Management: the consolidated portfolio of every project inside each program, with milestones, owners, status, risks, and dependencies.
• Orchestrate and roll up the portfolio of programs: maintain the enterprise-wide view while tracking each individual project, reconciling disparate updates from each program into one coherent, current picture.
• Set the project cadence across teams, programs, and operating companies: hold owners accountable for deliverables, manage timelines and dependencies, and align project work to enterprise deadlines such as audit cycles, reporting cycles, and assessment milestones.
• Own the roll-up reporting that consolidates the programs into one view; produce the recurring status updates and roadmap inputs leadership relies on; own how key project and program status is communicated to leadership and stakeholders

Run the Policy Lifecycle Process.

• Own the cadence, orchestration, and formalities of how Cybersecurity policies, guidelines, and processes get created, refreshed, and approved.
• Route policies authored by subject-matter experts across IT, Legal, HR, Compliance, and the businesses; own the approval workflow and the visibility of where every policy stands. Technical authoring remains with the subject-matter experts on the team.

Orchestrate Compliance and Assessment Reporting.

• Own the consolidated reporting view across compliance and assessments: the cadence, the consolidation, and how status is communicated to leadership. Subject-matter experts on the team identify the gaps and remediation paths.

Draft on Behalf of the CISO.

• Take half a brief and return a credible draft: executive staff updates, all-hands notes, leadership memos, and talking points, written in a voice that fits the audience, whether that's the Board, the C-suite, an all-hands crowd, or a vendor.

Steward the Team's Culture.

• Partner with the CISO to design and run team meetings, offsites, and recognition programs that strengthen cohesion of the Cybersecurity team across geographies and operating companies.
• Maintain a regular communication flow so the team stays connected to the work and to each other, and help the CISO show up consistently for the team.

EXPERIENCE

• 8+ years of project management experience, or equivalent, demonstrating increasing scope, responsibility, and impact in roles requiring strong organization, communication, and follow-through.
• 3–5 years of program management experience, or equivalent, owning a portfolio of initiatives, coordinating across teams, and driving outcomes to enterprise deadlines.
• Representative backgrounds include program or project management, executive support, business operations, strategy and operations, consulting, marketing, communications, or events/event planning; or related experience.
• Demonstrated experience operating at the enterprise level in a larger or matrixed organization, partnering with and influencing senior executives and driving outcomes across multiple business units or operating companies without direct reporting authority.
• Track record of writing for executive and board audiences and tailoring communications to varied stakeholder groups.
• A prior cybersecurity background isn't required, but if you have one, all the better. Exposure to GRC, IT risk, audit, compliance, or technology operations is a welcome plus.

EDUCATION

• Bachelor's degree in Business Administration, Communications, Marketing, Operations, Information Technology, or a related field; or an equivalent combination of education and experience. Advanced degrees are welcome but not required.

KNOWLEDGE AND SKILLS

• Enterprise savvy at the highest level: credible and effective among C-suite executives, the Board, and operating-company leadership; reads the room, manages up, and operates with executive presence.
• End-to-end operational ownership: combines strategic design with hands-on execution, working personally across event logistics, document production, meeting orchestration, communications, and portfolio reporting without relying on a coordinator behind the scenes.
• Disciplined follow-through and closure on commitments and action items, with the ability to follow up persistently and gracefully so that work lands without being chased.
• Strong written and verbal communication, with demonstrated ability to tailor content to the board, executive staff, all-hands audiences, and vendors, and to enforce a single, consistent voice across teams.
• Able to manage multiple concurrent workstreams, stakeholders, and competing deadlines with high reliability and minimal direction.
• Drives outcomes through stakeholders without direct reporting authority, building credibility quickly with peers across IT, Legal, HR, Compliance, the operating companies, and the businesses.
• Self-direction and sound judgment in ambiguous situations: produces credible drafts, recommendations, and decisions from limited briefs.
• Brand-builder instinct and marketing sensibility: translates technical content into engaging, accessible communications.
• Discretion and sound judgment in handling sensitive information, including incidents, personnel matters, audit findings, and executive conversations.
• Curiosity and willingness to learn the Cybersecurity domain on the job under the guidance of the CISO.
• Proficient Microsoft Office skills, with focus on PowerPoint, Word, and Excel; familiarity with collaboration tools such as Microsoft Teams, Loop, OneNote, and Planner; familiarity with a data-visualization platform such as Power BI, Tableau, or Domo is a plus.
• PMP certification is a plus.
