The Trade Desk

London

Principal UX Researcher.

STAFF LEVELDESIGN

The Trade Desk is a global technology company and the world’s leading independent platform for digital advertising, with over 3,000 employees across more than 30 offices. Our technology helps advertisers reach the right audiences across the open internet — from streaming TV and podcasts to mobile apps, news, and more. 

Advertising powers the content people love. By making it more transparent, effective, and responsible, we help support trusted journalism, quality entertainment, and creators worldwide. The world’s brands and agencies rely on us to reach their customers and grow their businesses responsibly.

The scale of our platform brings unique technical challenges — from processing massive datasets in real time to building systems that operate reliably on a global scale. When you work here, your impact is worldwide. We welcome diverse perspectives, encourage curiosity, and build teams that learn from one another. If you’re driven to solve meaningful challenges, we’d love to meet you.

What we do:

We are a fast-growing UX team that consists of innovators from Blizzard, Amazon, Google, Microsoft, Samsung, McKinsey Digital, and more. We are on a mission to build robust yet elegant solutions that challenge the world's best user-centered platforms. Our extraordinary cross-functional UX/UI team relentlessly experiments with platform technologies, advanced computing capabilities, and groundbreaking user interface methods to make our users' product experience seamless and natural. As a Principal Researcher, you will be part of a team that thrives on collaboration and communication. We are a tight-knit, passionate team aiming for our research and insights to have a massive impact at The Trade Desk and on the advertising ecosystem. We want to make advertising better for everyone involved, so our research spans advertisers, publishers, and consumers. Come bring your unique perspective to our team and help us build a research practice that will impact our customers, partners, and end users!

What you'll do:

  • Lead research across multiple product areas, partnering closely with product owners, engineering and design leads as well as our business counterparts.
  • Scope and complete strategic projects from early concepts through post-release measurement and iteration, integrating both qualitative and quantitative approaches along the way.
  • Lead and mentor a growing team of researchers, providing guidance and coaching to your colleagues on the UX and Product teams.
  • Be creative and resourceful in your approach to gathering insights, utilizing your relationships with clients and business partners, and knowing when to scale with vendors and secondary research.
  • Build relationships and collaborate with our business team on projects as well as conducting research with clients to understand their needs, problems and how to improve their end-to-end journey.
  • Influence and inform our product process - defining and evangelizing metrics and generating innovative ideas to expand our understanding of our users and our business.
  • Communicate and share insights from your research to the larger organization and identifying creative ways for the research team to share findings with a broader audience.
  • Drive aspects of building out our research infrastructure and operations (e.g., developing research programs, evaluating research tools, etc)

Who you are:

  • 12+ years of experience as a user researcher at a technology company
  • Possess the leadership skills to drive research programs to strategic impact using a breadth and depth of mixed method research approaches
  • You get to the “so what” and can synthesize data from multiple sources (primary, secondary) to surface insights that are valuable and feasible for the business
  • You have expertise in championing research and data-informed decisions across an organization and work with team members to identify areas of high impact for research.
  • You are comfortable working independently on complex or ambiguous problems and get creative when you have resource constraints.
  • You are a natural storyteller and know how to deliver your research findings to communicate in a way that engages stakeholders and diverse audiences, including executives.
  • You are passionate about research and stay up to date with the latest user research trends, best practices, technologies, and tools.
  • Research experience in B2B and advertising tech is a big plus.
