Lead Data Scientist



Lead Data Scientist

Are you a data science specialist? Do you have experience in constructing complex models from scratch and deploying ML models at scale? Do you enjoy coaching, mentoring and leading others in your field? If yes, then you might just be the Lead Data Scientist that we are looking for!

Every month, half a million new reviews are posted on Trustpilot for thousands of businesses in our review community. We have now reached 75 million reviews - and growing! - from consumers around the world. With this rapid growth also comes a massive amount of data, from which our Data Scientists build models that enhance our commercial practices and help our product teams build great features.

We are seeking a Lead Data Scientist to join us in our Data & Analytics function, working with departments across Trustpilot including Product, Content Integrity, Commercial and Engineering to construct, deploy and maintain models at scale, and to manage and mentor a small number of Data Scientists. To succeed in this role you should have a strong technical background as a Data Scientist, the proven ability to drive forward good working practices, knowledge of the interface between data science and engineering, the ability to engage with and influence stakeholders, and the ability to inspire and motivate others.

The Role
As Lead Data Scientist your focus will be on how we use and apply data science within the organisation to make data science a key part of our growth. You will ensure that our processes for creating and deploying production-ready ML models are best-in-class and that we remain up to date with the latest tools and techniques. You will use your analysis, modelling, text mining, and data engineering skills to uncover new knowledge and help identify new opportunities from data, constructing complex models whilst explaining them in simple terms. You will take the technical lead on some of our most exciting Data Science projects and you will be responsible for people leadership: managing and mentoring more junior team members. You will be part of Trustpilot’s mission to be an industry leader in the use of advanced modelling for safeguarding online content integrity.

You will be part of a specialised team that expects you to bring not just your Data Science experience but also great ideas and a positive mindset. In return, we offer you the opportunity to work with

leading data technologies including Google BigQuery, Airflow and AWS. You will work with multiple sources of data from our product and commercial systems and will have the opportunity to work across many areas of our business, from product to commercial to content integrity. The types of projects that you can expect to be involved in range from scoring models to natural language processing to pattern recognition. You’ll be joining a friendly, international, team of like minded people in central Copenhagen.
