About You

You’re an experienced and visionary product designer eager to drive innovation at the intersection of Marketing, AI, and data. You’re excited about shaping the future of marketing platforms, leading the creation of intelligent, intuitive, and impactful experiences. You thrive in ambiguity, move swiftly from concept to prototype, and influence strategy through strong design leadership.

You’re seeking an opportunity where you’ll:

• Have a “seat at the table” from Day 1, with stakeholders who deeply value your craft.
  
  
• Co-own the strategy and vision for an entirely new product experience.
  
  
• Push the boundaries of how AI can serve marketers through rich interactivity and data-informed design.
  
  

About the Role

This Principal Product Designer (PPD) will lead the design of early-stage, high-impact concepts that will shape the future of the Marketing Hub roadmap. The role will focus on concept prototyping, collaborating closely with PM and Engineering partners to develop proof-of-concept experiences and inspire long-term product strategy.

This role demands strong capabilities in AI design paradigms and interaction design and a commitment to delivering world-class user experiences. You’ll help create a new product methodology that empowers marketers in modern, intelligent ways.

We're open to candidates in Ireland or the UK, and you're welcome to work in office, hybrid or remote from these locations.

• Cross-Functional Collaboration: Act as a connective force between product, engineering, and executive leadership to align design direction with business strategy.
  
  
• Contribute to Design Systems: Ensure designs are scalable, consistent, and contribute to the evolution of HubSpot’s design system.
