Synthesia

Product Designer – Principal Level

Synthesia

Principal Product Designer leading design initiatives for Synthesia's AI video platform. Focusing on product strategy and aligning cross-functional teams in a hybrid environment.

About the role

Key responsibilities & impact
  • Lead large, complex, or ambiguous design initiatives across teams and surfaces - owning direction, success criteria, and long-term UX vision, not just execution.
  • Reframe problems, anticipate downstream risks, and bring clarity to spaces where product direction is still forming.
  • Operate as a strategic partner to Product and Engineering leads: helping define the right problems to solve, shaping long-term product bets, and bringing fresh insight to prioritisation decisions.
  • Prototype and test interaction models quickly, knowing when to go high-fidelity and when a rough concept moves things faster.
  • Drive alignment across teams and stakeholders beyond your immediate group - communicating complex ideas with confidence, clarity, and empathy, and helping leadership make sense of ambiguity.
  • Raise the craft bar across the design team: setting new standards in at least one design discipline and actively elevating the work of those around you.
  • Mentor and coach Senior Designers, contribute to evolving design team culture, and get involved in hiring and planning.
  • Help expand the design team's influence and reputation - inside the org, across the company, and ideally beyond it.

Requirements

What you’ll need
  • A track record of leading high-impact design work across large, ambiguous, or cross-functional problem spaces - and delivering outcomes that meaningfully shift product quality, clarity, or direction.
  • Recognised excellence in craft, in at least one design discipline, with a history of raising the standard for those around you.
  • Comfort operating without perfect clarity: you turn ambiguous problem spaces into crisp direction, and you don't wait to be handed a well-defined brief.
  • Systems thinking: you understand how product architecture, AI capabilities, and organisational constraints shape what's possible in the UX - not just what looks good on screen.
  • Strong strategic instincts: you frame the right problems, challenge assumptions, and contribute meaningfully to roadmap and prioritisation decisions.
  • Experience aligning diverse stakeholders and cross-functional teams around design decisions - communicating with confidence and empathy at every level.
  • Experience mentoring senior designers and contributing to team culture, hiring, or practice-building.
  • A genuine point of view on where product design is heading - and the credibility and communication skills to bring others along.

Benefits

Comp & perks
  • A flexible, remote friendly role based out of Europe or one of our hubs in London, Copenhagen, Munich, or Zurich.
