ZOE is the science and nutrition company leading a movement to transform the health of millions.

We exist because the food we eat is making us sick. Most of what we are taught about food is wrong.

ZOE runs the world’s largest nutrition science study to find scientifically proven solutions.

Our randomised controlled trial of ZOE proves that if you eat the right food for your body, you can feel healthier in weeks and be on track for more healthy years.

ZOE can change the way you eat, feel, and live. We host world-leading scientists on our podcast and bring proven science to your plate with Daily30+, our 30+ plant supplement.

Over 100,000 people rely on ZOE Membership, our personalised nutrition program, to make smarter food choices. ZOE Membership turns complex science into clear step-by-step actions, helping you improve your health with every meal.

ZOE means life — and you can change your life with food.

🚀 The Role

As a Data Scientist at ZOE, you will partner with world-class nutrition scientists to turn cutting-edge research into robust scoring algorithms and science-driven features, and to build ML/AI models that leverage our extensive members’ data to improve user experience and health outcomes.

Unlike a classical “fit-the-model” data science role, you’ll also engineer bespoke models that embed expert knowledge, validate them rigorously on real-world data, and ship production-ready code that powers the ZOE experience. You’ll collaborate daily with scientists, engineers, and product teams—moving fast and iterating quickly based on strong but not perfect evidence (~70 %) because speed beats perfection in a startup.

👥 The Team

You’ll be joining the Data Science team at Zoe. The team spends most of its time embedded in stream-aligned product teams while regularly setting aside a smaller portion of its schedule to drive high-impact, cross-cutting data science initiatives for the wider organisation.

Your home base will be the Scoring team—a cross-functional team of product managers, engineers, scientists, and data scientists that sits at the nexus of research and product. You’ll join a squad that prizes intellectual honesty, rapid experimentation, and our #ActFast ethos—working hand-in-hand with PhD scientists to turn hypotheses into deployed models.

🎯 What You’ll Be Doing

• Design, iterate, and deploy scoring algorithms for foods, diets, metabolic responses, and microbiome profiles.
• Translate expert food statements (e.g., ‘High-glycaemic foods raise blood glucose responses’) into model features and Python functions.
• Build, test, and maintain clean, production-ready code in Python (pandas, NumPy, scikit-learn), and SQL/DBT/BigQuery/Airflow.
• Build ML/AI models to improve food coverage and categorisation, ingredients extraction, food recommendations, and more.
• Design validation frameworks that blend scientific rigour (e.g., hold-out tests, bootstrapping, sensitivity analyses) with pragmatic speed.
• Partner with engineers to shape data contracts and ensure pipelines deliver the granularity, latency, and quality your models require.
• Present results using decks, dashboards, or Looms to support data-driven product decisions.
• Take full ownership of your work, brining entrepreneurial spirit and work proactively.  
• Champion our scientific yet agile approach: start with a hypothesis, seek evidence, and iterate fast.

🧠 What You’ll Bring to the Table

• 3+ years of professional experience in data science, ML engineering, or quantitative research.
• A degree in a quantitative field (e.g., Applied Maths, Physics, Biomedical Engineering, Statistics, Computer Science).
• Solid grasp of machine learning (e.g. training and evaluating standard models) and statistical techniques (e.g. running hypothesis testing).
• Experienced in contributing to production-level Python codebases, developing new components and features, writing moderately complex SQL queries, and using Git for version control.
• Experience turning domain knowledge (rules, heuristics, scientific findings) into engineered model logic.
• A track record of shipping production code and collaborating in cross-functional, fast-paced environments.
• Comfort using AI tools to enhance day-to-day productivity—from IDEs with AI assistants to prompt engineering.
• Strong communication and collaboration skills—from delivering clear presentations to stakeholders to conducting deep-dive code reviews and working collaboratively across functions.
• Must have a passion for nutrition, health tech, biology, or a strong desire to dive in and learn quickly.
• A commitment to our #ActFast value: optimise for reversible decisions, take smart risks, and move quickly with imperfect data.

🌟 Bonus Points

• Experience with causal inference and advanced statistical modelling.
• Experience with building AI features using LLMs and evaluation frameworks.
• Exposure to MLOps best practices.
• Knowledge of microbiome data, ---omics pipelines, or biomarker analytics.

✨ Our Hiring Journey

ZOE is a remote-first company, meaning remote work isn’t just an option — it’s how we work best. We are intentional about building a distributed, high-performing team where collaboration, trust, and flexibility thrive.

We design our workflows around asynchronous communication and shared documentation to support autonomy, focus, and cross-timezone collaboration. While our teams work independently, connection and teamwork remain central to how we operate — through regular rituals, meaningful virtual interactions, and in-person gatherings every quarter. These include team offsites and a yearly company-wide retreat to build relationships, spark creativity, and have fun together.

Being remote-first also means we value outcomes over hours and trust our team members to manage their work in a way that suits their unique rhythm and responsibilities. This approach allows us to support a truly flexible work environment, while staying aligned with our mission and values.

At ZOE, working remotely doesn’t mean working alone — it means being empowered, supported, and connected, wherever you are.

We are committed to offering competitive and equitable compensation that reflects the value of each role and aligns with regional labor market standards. Our approach to compensation goes beyond just base salary — we offer a comprehensive package that includes base pay and stock options, ensuring that every team member is rewarded for their contributions to the company’s growth and success.

We believe that building a thriving team requires not only providing fair and competitive compensation but also fostering an environment where success is shared collectively. Our total compensation package is designed to support the well-being of our employees, recognise their individual contributions, and empower them to grow alongside ZOE.

We understand the significant role our benefits play in motivating, inspiring and safeguarding our employees' well-being. Our benefits strategy is thoughtfully designed to echo our mission and values, recognising the diverse needs arising from different life stages of our ZOEntists.

Our approach to benefits takes an inclusive and flexible view of both personal and professional growth. From competitive health insurance and wellness packages to inclusive parental policies, building connection, and tailored professional development programs, we've got you covered.

At ZOE, we continue to build a benefits package that invests in our team members’ long-term personal and professional growth and wellbeing, adding to this list as it evolves.

We are committed to fostering a diverse and inclusive team where every individual can bring their authentic self to work.
