Data Scientist (Trust & Transparency)

A core value proposition of Trustpilot is Trust. We work hard to ensure that our platform has genuine content from real people with real experiences. That means eliminating fake reviews and acting on signs of suspicious behavior to protect our platform from fraudulent activity. Our Trust Applied AI team’s mission is to use advanced modeling to safeguard the integrity of online reviews, and we have several cross-functional teams devoted to Trust where Applied AI is integral to achieving our goals.

We are looking for a Data Scientist to join our Trust team. You and your team will work to develop, deploy, and maintain innovative models at scale, alongside a cross-functional team of software developers, product managers, ML engineers, and designers. You will have the opportunity to collaborate widely across the business with our Technology and Product teams. You will also work closely with stakeholders in Legal and Platform Integrity.

To succeed in this role, you should have proven experience in developing and deploying ML models. You need a strong technical foundation and hands-on experience in all stages of data preparation, exploration, and modeling. An adaptable mindset and understanding of the interface between Applied AI and engineering are essential as you will be working in cross-disciplinary teams. Experience with deploying solutions into production is expected, as you will be responsible for implementing end-to-end solutions—from data pre-processing to serving predictions.

What you will do:

• Be hands-on in delivering the Applied AI / Data Science component of key strategic projects in Trust, from building and fine-tuning language models to sequence modeling, anomaly detection, collaborative filtering, user segmentation, etc.
• Develop, maintain, and deploy production-ready ML models, with tooling support from ML engineers
• Engage with both technical and non-technical stakeholders and contribute to the Trust roadmap
• Seize the chance to meaningfully influence our business through the latest advancements in Applied AI and keep Trustpilot on the edge of innovation when it comes to fake review detection
• The opportunity to work with market-standard data engineering and deployment technologies including Google Vertex AI tools, Google BigQuery, and AWS, and with leading Data Science tools and emerging technologies for model building and deployment
• Opportunities to develop your career in a friendly, diverse, international team and workplace

Who you are:

• Experience with analysis and quantitative problem-solving using advanced statistical techniques and machine learning methods, e.g. anomaly detection, sequence modeling, classification, and semi-supervised/active learning, as well as deep learning methods (e.g. for language problems and graphs)
• Experience in building and deploying production-ready ML models at scale, and solid data engineering skills (e.g. experience with cloud technologies - we use GCP but experience with AWS or Azure will also be fine)
• Ability in Python and SQL for data manipulation, modeling, and scripting
• Experience in working with large datasets, ideally from tech platforms, e-commerce, or SaaS-type businesses. Knowledge of behavioral data, detecting misbehavior or fraud at scale is a big plus
• Knowledge of data pipelining and prior experience with cloud-based ML model deployments
• Great communication skills - both with technical colleagues and with business stakeholders 
• Proven 3+ years of technical experience in a Data Science role, particularly in the technology sector or in a technical consultancy

What's in it for you:

• A range of flexible working options to dedicate time to what matters to you
• Competitive compensation package + bonus
• 25 days holiday per year, increasing to 28 days after 2 years of employment 
• Two (paid) volunteering days a year to spend your time giving back to the causes that matter to you and your community
• Rich learning and development opportunities are supported through the Trustpilot Academy, LinkedIn Learning, and Blinkist
• Pension and life insurance
• Health cash plan, online GP, 24/7, Employee Assistance Plan
• Full access to Headspace, a popular mindfulness app to promote positive mental health
• Paid parental leave
• Season ticket loan and a cycle-to-work scheme
• Central office location complete with table tennis, a gaming corner, coffee bars and all the snacks and refreshments you can ask for
• Regular opportunities to connect and get to know your fellow Trusties, including company-wide celebrations and events, ERG activities, and team socials.
• Access to over 4,000 deals and discounts on things like travel, electronics, fashion, fitness, cinema discounts, and more.
