About the Role We are seeking a highly motivated Internal Communications Specialist to play a critical role in supporting employee communications during Blueprint Medicines’ integration into Sanofi. This is a unique opportunity to help guide employees through one of the most significant moments in the company’s history—supporting the transition from a ~600 person biotech to part of a global organization of ~80,000 employees. You will have hands-on ownership of highvisibility communications channels and will contribute directly to how change, clarity, and connection are delivered at scale. This role is ideal for someone with prior communications experience who is eager to take ownership, work crossfunctionally, and gain rare, resumedefining experience supporting a largescale enterprise integration.

Why This Role Matters Internal communications is a cornerstone of a successful integration. In this role, you will help ensure employees understand what’s changing, what’s staying the same, and how they are supported—at a moment when clarity and trust matter most. Your work will directly contribute to a smooth transition as Blueprint becomes part of Sanofi.

Who You Are · You bring 2+ years of communications experience (internships, contract roles, or fulltime experience welcome) · You are a strong writer and editor with a sharp eye for clarity, tone, and audience · You can manage multiple priorities and adapt as integration milestones evolve · You’re comfortable owning work independently while collaborating closely with crossfunctional partners · You’re curious, detail oriented, and energized by fast moving, high impact work

Requirements · Prior experience in communications, marketing, corporate affairs, journalism, or a related field · Comfort working in Microsoft 365 tools (Outlook, Teams, SharePoint) · Ability to work onsite in Cambridge, with flexibility for remote work · Strong organizational, planning, and time management skills

Why You’ll Love This Opportunity · Ownership of highvisibility, enterprisewide communications channels · Direct involvement in a largescale global integration · Exposure to communications at global enterprise scale · Close partnership with senior communications and crossfunctional leaders · Flexible schedule with meaningful, career accelerating work
