- We are a large-scale consumer marketplace building AI-native product experiences across multiple markets. Trust and Safety is not a defensive function here - it is a strategic growth lever. A platform users trust converts better, retains longer, and earns stronger word of mouth. Fraud, abuse, and bad actors actively destroy the value we create; eliminating them is product work at its core

- We are looking for a Lead Product Manager to own the Trust & Safety product agenda end-to-end. You will define the strategy for how we detect and prevent fraud, protect user integrity, and keep our marketplace safe - while building systems that are intelligent, proportionate, and do not create friction for the millions of legitimate users who rely on us every day

- AI is central to how you will do this: not as an add-on, but as the foundation of a new generation of proactive, signal-driven safety infrastructure

- Own the Trust & Safety product strategy and roadmap translating business risk and user insight into a clear, prioritised plan

- Shift the function from reactive incident response to proactive, intelligence-driven fraud prevention: build the Risk Engine, data signals intelligence, anomaly detection, and investigation tooling that make this possible

- Ship AI-native T&S; product experiences: partner with Data Science and Engineering to design, prototype, and productionise real-time detection and decisioning systems using ML models, LLMs, and behavioural signals

- Balance fraud mitigation with growth protection—ensuring T&S; interventions do not unnecessarily create friction for legitimate users or throttle marketplace supply/demand. Make hard, evidence-based trade-off decisions

- Define and track the right T&S; success metrics: fraud loss rates, false positive/negative rates, time-to-resolution, user trust scores, and financial exposure. Communicate impact in business terms to senior leadership

- Partner closely with Engineering leads, Data Science, Legal, Compliance, and Operations—holding shared accountability for outcomes and navigating competing priorities

- Build long-term instrumentation, monitoring,



and evaluation capabilities to measure fraud rates, detection model performance, and contributor/user impact at scale

- Establish business cases quantifying fraud losses and ROI of prevention investments; secure resources and drive prioritisation grounded in data

- Ensure products and strategies meet local and regional compliance, legal, and security requirements across all markets

- Apply AI to how you operate as a PM: faster threat analysis, synthetic user research on abuse patterns, AI-assisted spec writing, automated experimentation pipelines—whatever moves the needle on velocity

- Represent Trust & Safety at the leadership level, presenting strategy, risk posture, and results clearly to executive audiences

Benefits

- Range of development programs and resources designed to help you thrive in a way that suits you

- Unlimited therapy and coaching sessions through our BetterUp partnership

- ‘Speak Up’ (87% of our employees say they feel able to speak openly and not shy away from difficult conversations)

- Quarterly engagement surveys
- Hybrid working set-up (differs for each role)- Experience building, deploying, or working closely with machine learning, AI, risk scoring, decisioning, detection, recommendation, or automation systems. Hands-on experience with AI-powered trust or fraud products is a plus

- Well versed in building, iterating core Data (Science) products at scale

- Strong analytical and data driven mindset, with experience defining success metrics, evaluating impact, and making prioritization decisions based on evidence and measurable outcomes

- Strong core product muscle that transfers across fraud domains—you’ve stepped into unfamiliar threat vectors, oriented fast, and delivered.



Domain specificity matters; rigid domain lock-in does not

- Track record of building scalable systems that proactively detect, prevent, and mitigate abuse, fraud, risk, or other trust related issues, rather than relying solely on manual or operational processes

- Significant product management experience in the digital sector: consumer facing platform, marketplace, mobility, e-commerce, classifieds, fintech, or similar high scale environment

- Comfortable operating in ambiguity, taking ownership of complex problem spaces, influencing senior stakeholders, and driving strategy and execution across multiple teams

- Experience partnering closely with Engineering, Data Science, Operations, Legal, Compliance, and other cross-functional stakeholders to deliver complex products in regulated or high-risk environments.

Experience in vendor management and collaboration

- Demonstrated ability to balance user experience, marketplace growth, operational efficiency, and risk mitigation, making thoughtful trade offs that protect both users and the business

- Proven experience owning trust related products or problem spaces such as Trust & Safety, Fraud Prevention, Risk, Identity & Verification, Marketplace Integrity, Account Security, Abuse Prevention, Payments Risk, or Compliance Technology

- If you’re excited by the opportunity to solve complex trust challenges at scale and build products that make a meaningful difference to millions of users, we’d love to hear from you. This is a role for someone who enjoys tackling ambiguous problems, partnering across disciplines, and shaping the future of trust in a modern, AI-powered marketplace

- If this role excites you, we encourage you to apply, even if you don’t meet all the requirements - you may be just the right fit for this or other opportunities with us!

- Experience building trust, risk, fraud, or safety products across multiple international markets and regulatory environments

- Familiarity with emerging regulations and industry trends affecting online platforms, digital marketplaces, payments, AI, and consumer trust
