Lead Data Scientist - Full Time in London

The way we live, work and travel has changed. At Zego, we're leading the AI evolution in insurance. We move fast, without the layers that usually slow things down. AI takes the routine work off every team, from Finance to Product to Marketing, so people ship real code and launch custom dashboards in minutes. Engineering commits are entirely AI-assisted, which shifts the focus from team size to the quality of your thinking, and our data warehouse connects directly to an AI assistant for instant answers. Backed by a modern tech stack (Claude Code, Snowflake, Figma and Zapier) and a commitment to adopting new tools in days rather than quarters, you get complete ownership to do the most impactful work of your career.

Purpose of the role

We don't build pricing models, we build the driving intelligence that feeds them. Our mission is fairer insurance, priced on how people drive, not on who they are, and safer roads. The Telematics team turns raw phone sensor data into meaningful signals about how people drive. Using signal processing and machine learning on high-frequency GPS, accelerometer, and gyroscope data, we extract the behavioural features that power Zego's understanding of driving quality, context, and risk.

The Telematics Data Science team collaborates daily with engineering, product, and actuarial colleagues across the UK and PT. PT and UK roles carry the same scope, ownership, and progression. Decisions get made where the work happens, not in a single headquarters. This isn't a solo remote seat; few teams use phone sensor data to price commercial motor insurance at scale. As a Lead Data Scientist, you'll shape how millions of trips are turned into risk signals. You'll own behavioural features and algorithms from hypothesis to production, working at the intersection of data science and engineering on GPS, inertial, and other sensor data. You'll move between quick heuristics and full ML models depending on what the problem calls for. You ship code to production, not just notebooks.

Requirements

What You'll Be Doing

• Work with raw, high-frequency sensor data: This isn't warehouse-tabular data: it's noisy, physical, and where the signal actually lives.
• Research new behavioural features and detection algorithms: read the literature, try ideas, kill the ones that don't survive contact with real data.
• Design and build behavioural features and factors that feed Zego's understanding of driving quality, context, and risk.
• Take ideas from hypothesis to production: prototyping in notebooks, then writing the production-grade Python and SQL that scales.
• Prioritise simple, robust solutions, rule-based when that's enough, ML when it's warranted.
• Lead experiments, validate impact with data, and automate insight generation.
• Collaborate closely with software engineers, product managers, and actuaries to get features into the pricing path and measure their effect on real policies.
• Translate complex sensor data into clear findings that non-technical stakeholders can act on.

About You

• MSc (or integrated MEng/MSc) in a quantitative field: Engineering, Computer Science, Physics, Mathematics, or similar. This is a core role that requires strong engineering foundations.
• Working knowledge of digital signal processing or sensor physics.
• Proven track record delivering data science or data engineering projects into production.
• Strong Python and SQL (we use Snowflake).
• Comfortable with the scientific Python stack: Experience developing and evaluating ML models on tabular data classification or regression tasks where evaluation matters as much as model choice.
• You've designed, built, and maintained data pipelines from scratch: reliable, observable, and scalable.
• Fluent with AI coding assistants as part of daily engineering work. You work AI-first. You will use AI daily here, and we mean daily.

Nice to Have

• Experience applying signal processing to noisy, high-frequency sensor/time-series data (GPS, accelerometer, IMU) in production.
• Exposure to insurance, mobile data, or behaviour modelling.
• Experience with cloud platforms (AWS), containerisation (Docker, Kubernetes), or data orchestration frameworks.
• Familiarity with our ML and tooling stack: MLflow for experiment tracking, DVC for data versioning, Streamlit for internal apps and demos.

Working here means having the backing, the coaching, and an inclusive community of Zegons across the UK and Europe who celebrate your wins and raise your game. It also means holding ourselves to high standards: moving with urgency, taking complete ownership, and embracing honest feedback that helps us continuously learn and evolve. This is your opportunity for a career-defining experience, and one you will own. We call it Zego Hybrid: some of us are in our central London office weekly, others monthly or quarterly.

Benefits

• Market-competitive salary, benchmarked against your function and reviewed every year.
• Annual performance bonus, linked to company performance and your contribution.
• Share options, a real stake in the company and a share in the future you build.
• Private medical insurance, for you and your family.
• Pension, generous holiday, and £1,000 a year to spend on getting to the office or learning something new.
• Cutting-edge systems and tools, so you always have what you need to drive your impact.

If you're ready to help build the real-time, data-driven infrastructure for an intelligent world, we want to hear from you. Zego, leading the AI evolution in insurance.
