Job Description:

We’re looking for a Senior UX Researcher to bring clarity, evidence, and direction to complex product decisions across our Creator and Advertiser experiences and support our ambitious strategy for 2026 and beyond. You’ll operate end-to-end: shaping discovery, validating direction, and measuring impact post-launch. This is a hands-on senior IC role with high autonomy and strong influence across Product, Design, Engineering and beyond.

Job Responsibility:

Own and drive end-to-end research across multiple product areas (focus on Creator Hub and Advertiser Hub)
Partner closely with Designers and Product Managers to shape problem definitions, not just validate solutions
Collaborate closely with Business Intelligence
Help teams move from opinions and assumptions to evidence, without slowing delivery
Plan and run generative research to uncover unmet needs, motivations, and behavioural patterns
Translate research into clear, actionable insights that influence roadmap and prioritisation
Identify cross-product themes and systemic issues, not just local UX problems
Design and run usability testing, concept testing and prototype validation (early and often)
Support design teams with fast, pragmatic feedback loops
Know when “good enough” is good enough
Confidently combine qualitative insights with quantitative signals (product analytics, experiments, surveys)
Collaborate with BI and Product to define success metrics and measure impact
Improve how research is documented, shared, and reused across the organisation
Contribute to scalable research practices, templates, and standards
Champion ethical, inclusive, and accessible research practices

Requirements:

7+ years of UX research experience, with time spent in complex digital products (marketplaces, platforms, B2B, SaaS, or similar)
Strong hands-on experience with a wide range of qualitative methods (interviews, usability testing, diary studies, concept testing)
Comfortable working with quantitative data and collaborating with analytics partners
Ability and experience in combining qualitative, quantitative and data for holistic view of a question / problem
Proven ability to influence product direction, not just produce reports
Clear, confident communicator who can bring stakeholders along for the ride
Comfortable with ambiguity, shifting priorities, and imperfect information

Nice to have:

Experience in media, creator tools, advertising, or marketplaces
Experience researching multi-sided platforms (e.g. creators ↔ advertisers)
Familiarity with accessibility and inclusive research practices
Experience working in international, distributed teams
