Junior Business Analyst jobs in United Kingdom

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models.

The role

We’re hiring a Senior Business Analyst to join our central Business Analytics team. You’ll partner closely with senior stakeholders across Prolific to deliver high-quality analytics, strategic insights, and proactive discovery that shape company direction.

This is a high-visibility, high-impact role ideal for someone who:

• is exceptional at translating data into clear, actionable recommendations and can independently drive analysis end-to-end
• turns complexity into crisp, actionable, business-ready insights
• enjoys shaping structure in ambiguous spaces — e.g., defining what “healthy marketplace dynamics” look like across supply, demand, and pricing
• brings strong judgment, navigates trade-offs, and adapts quickly in a fast-moving environment
• is energised by the intersection of data, product thinking, and operational strategy

What you’ll bring to the role

• Proven experience working with senior leadership to shape decisions
• Ability to understand business drivers across GTM, Finance, Support, CX, and Product, and connect them to insights
• Ability to influence without authority, build cross-org alignment, and challenge assumptions constructively
• Strong judgment and comfort navigating ambiguity, trade-offs, and competing priorities

• Exceptional communicator able to synthesise data into compelling stories and clear recommendations
• Experience developing KPI frameworks, performance diagnostics, and insight narratives that drive action
• Bias for clarity, precision, and “so-what” impact

• Actively identifies opportunities and issues before they surface — e.g., spotting early signals of supply constraints, demand shifts, or emerging risks
• Comfort structuring ambiguous areas from first principles — e.g., defining what “healthy marketplace dynamics” look like across supply and demand
• Ability to ask (and reframe) the right questions to unlock insight

• Familiarity with marketplace or B2B metrics; experience in a marketplace environment highly valued
• Solid understanding of how operational signals roll up to financial outcomes
• Commitment to analytical excellence — including documentation standards, templates, and peer-review processes
• Deep interest in AI systems, human-in-the-loop evaluation, or responsible AI (experience valued but not required)
• Strong experience with modern BI tools (Metabase, Looker, Tableau, etc.). Experience with dbt/semantic models highly desirable.
• Ability to design scalable dashboards, models, and workflows that hold up under executive scrutiny
• Strength in turning complexity into clarity — high-quality, business-ready outputs

What you’ll be doing in the role

• Lead high-impact analyses that clarify performance, diagnose issues, and inform strategic decisions
• Build KPI frameworks and business-health reporting tailored to senior leadership
• Own analytical workstreams feeding business reviews, forecasting inputs, and executive updates

• Act as a trusted partner to senior leaders, providing clarity, structure, and insight
• Drive alignment on metrics, definitions, and success criteria across teams
• Translate analysis into clear next steps that enable accountability and action

• Identify leading indicators, emerging risks, and opportunities ahead of time (e.g. spotting early signals of supply constraints or demand shifts)
• Understand the mechanics of our marketplace deeply and connect patterns across supply, demand, pricing, operations, and customer behaviours
• Highlight where interventions are needed and recommend strategic and operational responses

• Build scalable dashboards and reporting that underpin decision-making across the business
• Work closely with analytics engineering to improve data models and ensure consistency
• Contribute to improving team processes — documentation, analytical templates, and peer-review standards
