Data Scientist. LilyLifestyle

Join our team at the Guardian and be a part of a diverse and inclusive global organisation that delivers fearless, investigative journalism, and holds power to account. Our team of award‑winning journalists, cutting‑edge commercial professionals, and industry‑leading digital experts are committed to making a difference and represent a wide range of backgrounds and perspectives. We offer a challenging and exciting environment for career development, with a focus on training, growth and fostering an inclusive culture.

We are now looking for a Data Scientist to join our Data Science team! You'll take on end‑to‑end problems and turn ambiguous questions into analysis, models, and recommendations that teams can act on.

We keep things practical and focus on what works. Our data primarily lives in Google Big Query, and we also work with off‑platform data sources such as social media. We use a mix of Amazon Web Services and Google Cloud Platform for infrastructure, and Apache Airflow powers our pipelines and orchestration. We mostly use Python and SQL, though we pick up other languages and other tools as the work demands.

• Own data science projects from problem definition to delivery, independently delivering impactful projects across the editorial, marketing, advertising, product and engineering departments.
• Understand what makes stories reach and engage audiences, support content discovery and tagging systems, analyse how editorial decisions influence performance and help journalists find leads and insights in large datasets.
• Model reader conversion, churn, and engagement with products, segmenting audiences to support growth and supporting marketing campaign and product optimisation.
• Optimise advertising campaigns, enrich content metadata for advertising purposes and help teams make better decisions with imperfect data.
• Deploy data solutions in close collaboration with the engineering team, embedding models into existing tools and workflows.
• Work on improvements at every step of the Machine Learning lifecycle.

• Strong experience in Python and SQL, experience working with data in Big Query would also be beneficial.
• Excellent command of statistics and machine learning (NLP experience a bonus).
• Proven track record delivering end‑to‑end analysis or modelling projects.
• Ability to communicate clearly with both technical and non‑technical audiences.
• Comfortable working with ambiguity and incomplete information.

We operate in a hybrid environment working 3 days a week from our offices in Kings Cross and 2 days a week remotely.

All roles at the Guardian are open for everybody to apply.

You'll have 30 days of annual leave per year (plus bank holidays) with the option to purchase an additional 5 days. Our pension scheme is generous; if you contribute 5% then we will contribute 8-12% (depending on your age). We believe in giving back, which is why employees are given 2 volunteering days annually and the option of payroll giving. Season ticket loans are also available.

You are entitled to private healthcare, life cover, income protection, and eye tests. You can also opt in to dental insurance.

We have enhanced maternity, paternity, adoption and shared parental leave policies in place. We also support our employees by offering an IVF, menopause, baby loss, and trans equality policy.
