Our growth in the last year has been phenomenal – people are looking for love and we’re helping thousands of people around the world get married every month.  We’re looking for an experienced and strategic Senior User Researcher to join our growing UX team in London. As a senior member of the creative squad, you will lead impactful research initiatives that inform our product decisions and play a critical role in evolving our UX culture.

What you’ll do:

Join our UX team of 7 – a talented group of product designers with varying levels of experience – and help us shape the future of our Muslim marriage app. As our Senior User Researcher, you’ll own the research function and work cross-functionally to ensure our product decisions are grounded in deep user understanding.

  • Lead research projects: Take ownership of your designs from start to finish, ensuring they meet our high standards of quality and align with our product vision.
  • Upskill the team: Share research best practices and help grow research capability across the design team, particularly supporting junior and mid-level designers in applying user-centered methods.
  • Collaborate cross-functionally: Partner with product managers, data analysts, and stakeholders to bring user needs to the forefront of decision-making.
  • Improve research operations: Establish and refine scalable research practices, helping our team become more insight-led and efficient.
  • Champion evidence-based design: Promote a culture of user-informed thinking through impactful storytelling and clear communication of findings.
  • Uncover deep user insight: Use a mix of qualitative and quantitative methods to reveal user behaviours, needs, and motivations.
  • Contribute to UX strategy: Play an integral role in shaping our long-term UX and product vision through insight-driven input.
  • Stay current: Keep up with emerging trends in research methods, ethics, and tools to continuously improve how we learn from our users.

What we're looking for

We’re searching for a Senior User Researcher who is thoughtful, collaborative, and passionate about making a difference through user understanding.

  • Excellent soft skills: You’re a clear communicator who builds trust, simplifies complexity, and thrives on collaboration.
  • Industry experience: At least 6 years of hands-on UX research experience in digital products, ideally B2C.
  • Impact-driven mindset: You care deeply about solving meaningful problems and ensuring user needs are never an afterthought.
  • Comfortable leading solo: You’ll be the primary research voice in the team and must be confident driving the discipline forward independently.
  • Team-oriented: While you lead on research, you enjoy collaborating with and enabling designers to strengthen their own research confidence.
  • Culturally sensitive: Understanding and respecting Muslim culture and traditions is crucial for this role.

Requirements

  • 6+ years of experience conducting UX research in product-led teams.
  • Experience designing and executing a broad mix of research methods: usability testing, interviews, focus groups, field studies, surveys, etc.
  • Strong portfolio or case studies demonstrating how your research influenced product decisions and delivered value.
  • Ability to work effectively in agile teams and communicate insights to cross-functional audiences.
  • Deep understanding of user-centered design principles and UX best practices.
  • Based in or able to commute to London 2 days per week.
  • Have current and valid eligibility to work in the UK

Bonus Points…

  • Experience in the dating, marriage, or social connection space.
  • Familiarity with digital analytics tools (e.g., Amplitude, Mixpanel) and triangulating data sources.
  • Previous work in a fast-moving startup environment.
