Job Description:
Most M&A roles stop at the closing dinner or start after the ink is dry. At Vertex, you will bridge both.
We are seeking an execution-focused Director, Corporate Development & M&A Integration , to connect acquisition strategy and transaction execution directly to post-merger value creation. As Vertex accelerates its global cloud and AI-enabled compliance expansion, you will ensure every acquisition—from high-velocity capability tuck-ins to regional e-invoicing and platform expansions—delivers on its investment thesis, protects customer and talent retention, and drives durable recurring revenue growth.
At Vertex, we help businesses navigate the complexity of global indirect tax and compliance with confidence. Since 1978, we have combined deep tax expertise with enterprise software to support the full transaction lifecycle—from tax determination and e-invoicing to reporting, filing, and audit defense. Today, more than 60% of the Fortune 500 trust Vertex to manage their global compliance needs. By connecting tax domain leadership, cloud technology, and responsibly applied AI, we help enterprises reduce friction, gain visibility, and transact and grow globally.
The Opportunity
Sitting at the intersection of corporate development and our Integration Management Office (IMO), the Director, Corporate Development & M&A Integration leads end-to-end deal execution and post-acquisition integration across the full transaction lifecycle.
Partnering closely with the Chief Strategy Officer, CSO organization, Corporate Development leadership, and cross-functional executives, you will evaluate market adjacencies, build investment business cases, orchestrate cross-functional due diligence, and translate diligence findings directly into Day 1 readiness and 100-day value-capture plans. Success in this role requires a collaborative leader who builds immediate credibility with C-suite and functional stakeholders, influences without relying on formal line authority, and balances public-company governance with the operational agility needed to integrate founder-led and international software teams.

- Orchestrate end-to-end due diligence across Product & Engineering, Tax Content, Cybersecurity & Data Privacy, Commercial/GTM, Finance, HR, and Legal—translating diligence findings directly into a binding pre-close integration charter prior to signing.
M&A Integration & Value Realization
- Design deal-specific integration strategies matched to each transaction archetype—protecting acquired engineering and product velocity on capability tuck-ins while integrating commercial, security, and compliance foundations.
- Build, standardize, and continuously refine Vertex's IMO playbooks, templates, RAID logs, dependency maps, and post-mortem feedback loops.
- Lead cross-functional teams through pre-close Day 1 readiness (entity close, payroll/benefits continuity, customer assurances, and security baselines) as well as disciplined Day 30, Day 100, and Day 365 execution plans.
