At Squarespace, we empower product teams to solve meaningful customer & business problems. Were looking for a Senior Product Manager to lead Acuity Messaging & CRM, the team responsible for the communication tools & infrastructure that help appointment-based businesses stay connected with their clients across the scheduling journey.

For service businesses, strong client relationships drive retention, growth, & operational efficiency. Messages like confirmations, reminders, reschedules, & follow-ups reduce no-shows, set expectations, & reinforce trust. By owning the systems that power these communications at scale, youll help our customers run more reliable businesses while delivering clear, timely experiences to their clients.

In this role, youll own Acuitys Messaging & CRM products across email & SMS, including reminders, notifications, & lifecycle messaging. Youll also steward the underlying platform that ensures these messages are delivered reliably, securely, & cost-effectively. This role sits at the intersection of platform ownership & B2B2C product design: building intuitive tools for businesses while ensuring their clients receive communication that strengthens the customer relationship.

This is a hybrid role, requiring 3 days a week in our Aveiro, Portugal office. You will report to the Senior Group Product Manager on the Acuity Scheduling team.

• Define & execute a strategic, monetizable roadmap for Acuitys client messaging products across email & SMS
• Partner with engineering to deliver a scalable, compliant, & resilient messaging platform
• Own relationships with external integration partners to restructure & optimize current integrations while evaluating new functionality to expand Acuitys messaging capabilities
• Collaborate with cross-org Squarespace stakeholders to align on a unified CRM strategy while supporting Acuitys specific client & entity needs
• Build intuitive tools that let businesses easily create, customize, & automate communications
• Monitor system health, reliability, abuse risks, & cost efficiency, driving improvements that protect customer trust
• Use data, experimentation, & user research to measure impact & inform prioritization

Who We're Looking For

• 78+ years of product management experience, ideally in messaging platforms, communications infrastructure, or lifecycle automation
• Experience working with external providers such as Twilio, SendGrid, or similar communication platforms
• Strong technical fluency, comfortable partnering on API-driven systems & service-oriented architectures
• Proven experience owning partner relationships & driving roadmap alignment, integration improvements, or adoption of new platform capabilities
• Clear communicator who can translate technical complexity into intuitive product experiences
• Customer-obsessed, with a track record of shipping meaningful, high-impact products

Nice to Have
