We understand you may feel confident ticking certain boxes more than others and that’s why we always keep an open mind in our recruitment process. But, in order to thrive in this role, we do believe you’ll have at least some experience in the following: 

• Proven track record leading end-to-end ML or data science projects, from problem definition to production deployment
• 5+ years of hands-on experience in applied Machine Learning or Data Science in production environments
• Strong grasp of statistical modeling, ML algorithms, and their real-world applications
• Advanced skills in Python, with solid proficiency in SQL and Apache Spark (or PySpark)
• Experience deploying models in cloud environments (preferably AWS) using Docker or similar tools
• Familiarity with Airflow or other orchestration tools for building and managing ML pipelines
• Excellent communicator, able to explain complex concepts to both technical and non-technical audiences
• Degree in Statistics, Mathematics, Computer Science, or a related quantitative field

It’s a bonus if you have: 

• Experience with A/B testing platforms and causal inference methods
• Knowledge of MLOps practices (CI/CD, monitoring, retraining)
• Experience mentoring data scientists or providing technical leadership

What we offer you 

• We’ve got you covered! 30 days of paid vacation every year, an attractive pension and insurance scheme, and generous parental leave pay lift.
