• Develop, manage, and track detailed project plans across functional workstreams (HR, Finance, Marketing, Technology, Legal, Operations, etc.).

• Partner with internal stakeholders and functional leaders to define priorities, resolve issues, and ensure alignment and execution.

• Monitor and report on progress, milestones, risks, and interdependencies to executive leadership.

• Proactively identify and mitigate integration risks, dependencies, and roadblocks.

• Drive effective change management and communication across internal and acquired company teams.

• Translate strategic integration goals into actionable plans, ensuring hands-on delivery and measurable outcomes.

• Establish clear governance and reporting structures for integration initiatives.

• Support post-integration reviews and continuous improvement efforts to capture learnings and refine future playbooks.

• 5+ years of experience in post-merger integration, corporate development, management consulting, or similar program management roles.

• Proven M&A integration experience, ideally having led or played a key role in multiple acquisition integrations.

• Strong track record in cross-functional project management, coordinating across Finance, HR, IT, Operations, and other corporate functions.

• Excellent program and project management skills with the ability to manage multiple complex workstreams simultaneously.

• Exceptional communication, stakeholder management, and influencing skills — confident working with senior executives.

• Strong analytical and problem-solving abilities, with meticulous attention to detail.

• Comfortable operating in fast-paced, ambiguous environments and adapting quickly to change.

• Highly self-motivated and able to work independently with minimal direction.

• Experience in change management, business transformation, or organizational design is advantageous.

• PMP, PRINCE2, or equivalent project management certification.

• Experience in private equity-backed or high-growth companies.

• Proven success implementing cross-functional process or systems changes.

• Background in management consulting or corporate strategy.

• A high-impact, visible role at a pivotal stage in company growth.

• Opportunity to shape and execute the integration strategy from the ground up.

• A collaborative, fast-paced environment with strong executive sponsorship and support.
