Role Overview

As a Data Scientist in our Experimentation team, you will help deliver and improve Tripledot’s company-wide experimentation analysis platform. Working closely with Data Engineering, you will define the statistical logic and methodologies behind platform features, build prototypes in Python, and ensure the platform produces accurate, reliable results for product teams across our games portfolio.

Your initial focus will include hands-on quality assurance: running independent analyses, comparing results with platform outputs, investigating discrepancies, and validating features and metrics. This offers the opportunity to develop deep expertise in experimentation and A/B testing across a sophisticated internal platform. As the platform evolves, the role will expand into more advanced statistical and machine learning work that delivers value across the business.

Key Responsibilities

• Define statistical logic, calculation methods, and detailed requirements for experimentation platform features.
• Prototype statistical methodologies and analyses in Python before implementation.
• Partner closely with Data Engineers as they develop and improve the experimentation platform.
• Perform thorough data and feature QA by independently calculating results and comparing them with platform outputs.
• Investigate discrepancies, identify root causes, and help ensure metrics and analyses are accurate and reliable.
• Explore opportunities to automate QA processes and improve the efficiency and quality of validation.
• Build a deep understanding of experimentation methodologies, including A/B testing, monitoring, segmentation, and analysis.
• Collaborate with BI, Machine Learning, product teams, and other stakeholders to understand requests and shape effective solutions.
• Contribute to future statistical, algorithmic, and machine learning initiatives as the team’s priorities evolve.

Skills, Knowledge and Expertise

• 3-5 years of professional experience as a Data Scientist or in a closely related role
• Strong Python skills, including the ability to prototype analyses and write clear, reliable scripts.
• Solid knowledge of statistics and standard statistical methodologies.
• Practical understanding of experimentation and A/B testing, including how metrics and results should be calculated and validated.
• Familiarity with machine learning methods and the ability to apply relevant approaches when needed.
• Excellent attention to detail and a disciplined approach to repetitive or methodical QA work.
• Strong problem-solving skills, with the initiative to propose creative solutions and process improvements.
• Clear communication skills and the ability to explain analytical methods, results, and rationale.
• Experience with experimentation platforms or high-volume digital products, such as gaming, e-commerce, or ride-hailing, would be valuable.
• Ability to critically evaluate and validate AI-generated code, analyses, or modelling suggestions to ensure correctness and reproducibility.
• Experience using AI-assisted tools (e.g. code assistants or analytical copilots) to accelerate data exploration, research prototyping, and development workflows while maintaining scientific and statistical rigor.
• Interest in exploring AI-driven approaches that improve experimentation platforms, developer productivity, or data science research workflows.
