M&A Integration Manager (Hybrid) in Marlborough, Massachusetts at Wind River Environmental LLC

Location: Hybrid (Flexible) | Must reside within Wind River Environmental’s operating footprint

Compensation: $125,000 – $150,000 base + 10% bonus

Own the Execution Behind High-Volume M&A

Wind River Environmental is one of the most active acquirers in our space, having completed 50+ acquisitions and continuing to execute 7–8 deals per year.

We’re looking for an M&A Integration Manager to take ownership of how those deals come to life.

This is a high-visibility role where you won’t just “support” integration - you will own and improve the integration process, working directly with executive leadership and cross-functional teams to ensure every acquisition delivers on its potential.

If you have M&A experience and are looking for a role where you can drive execution, build scalable processes, and make a measurable impact, this is that opportunity.

What You’ll Do

You’ll serve as the central integration leader, responsible for translating deal strategy into execution across multiple concurrent acquisitions.

Lead Integration Execution

• Own the end-to-end integration process from pre-close planning through post-close execution
• Drive Day 1 readiness and ensure smooth transitions for newly acquired businesses
• Manage multiple integrations simultaneously in a high-volume deal environment

Run the Integration Program

• Coordinate across Operations, IT, HR, Finance, and Corporate Development
• Establish clear ownership, timelines, and accountability across all workstreams
• Lead integration meetings, track progress, and provide updates to leadership

Shape and Improve the Playbook

• Identify opportunities to improve integration speed, consistency, and outcomes
• Build and refine integration tools, templates, and best practices
• Help scale the company’s integration capabilities as acquisition activity grows

Support Deal Execution

• Coordinate non-financial diligence across functional teams
• Identify operational risks and translate diligence insights into integration plans

Drive Systems & Process Integration

• Support the alignment of systems, data, and operational processes
• Partner with IT and Finance to ensure clean transitions and reporting consistency

Partner with Leadership

• Work closely with C-suite executives and senior leaders
• Build strong relationships with acquired company leadership teams

Who This Role Is Perfect For

This role is ideal for someone who:

• Has M&A or integration experience and wants to own execution, not just analyze it
• Thrives in a fast-paced, deal-driven environment
• Enjoys managing complexity and driving alignment across teams
• Wants visibility to executive leadership and the opportunity to influence outcomes
• Is excited to build and improve processes, not just follow them

What You Bring

• 5+ years of experience in project management, operations, or M&A/integration roles
• Proven ability to manage multiple cross-functional projects simultaneously
• Strong organizational, problem-solving, and communication skills
• Experience working across teams and driving accountability without direct authority
• Comfort operating in a dynamic, high-growth environment
• Experience with systems, data, or process integration is a plus
• Proficiency in Excel, PowerPoint, and project management tools
• Willingness to travel up to ~15%

Location & Travel

• This is a hybrid role with flexibility in work location
• Candidates must reside within Wind River Environmental’s operating footprint across the East Coast to support travel and integration activities
• Travel is expected (~15%) to acquired business locations as needed

Why Join Wind River Environmental

• High deal volume: Be at the center of 7–8 acquisitions per year
• Real ownership: Lead integrations - not just track them
• Executive exposure: Work directly with senior leadership and decision-makers
• Career growth: Build a skillset spanning operations, M&A, and strategy execution
• Impact: Your work directly drives the success of each acquisition
