Staff Product Manager, Developer & App Ecosystem

At Squarespace, we empower our product teams to solve complex customer and business problems in ways that delight users and drive meaningful results. As a Staff Product Manager, you will operate as a senior-level individual contributor, driving strategy, execution, and cross-functional alignment across high-impact areas of our platform.

The App Ecosystem team is core to the Squarespace Commerce experience. We help sellers across the globe extend and customize their storefronts and back-office systems by enabling powerful third-party integrations. Our work spans the foundational APIs and developer tools that underpin app development on Squarespace, making this one of the most critical and interconnected surfaces in the entire product ecosystem.

This is a unique opportunity to lead initiatives that expand the scope and sophistication of our commerce platform. You’ll shape the long-term API strategy that enables both service and product sellers to build custom workflows and tailored experiences for their businesses. Your work will help grow our Extensions Store, scaling our platform's utility and flexibility.

You will report to a Senior Group Product Manager and will be based in our Dublin, Ireland office working on-site (hybrid 2-3 days per week in office).

• Discuss APIs and technical details with engineering, while staying focused on what sellers need and how it all fits into the bigger picture.
• Lead complex, cross-functional initiatives from inception to delivery, driving accountability while fostering a collaborative culture.
