Research Scientist, Causal Inference

• ~160 people, around half in engineering, product and data
• 45+ advanced degrees across computer science, mathematics and operations research
• Thousands of data points captured, calculated, analysed and predicted for every single parcel we handle
• An intellectually vibrant culture of first‑principles thinking, tight feedback loops and relentless experimentation

Relay makes millions of dynamic, interconnected decisions across its network every day, and each one shapes the experience of the thousands of couriers who work with us. Knowing what any one of those decisions actually did is hard: couriers interfere with each other, effects vary from person to person, and the outcomes that matter compound over time.

Science at Relay is the brain of the operation: machine learning, operational research, recommender systems, causal inference, location intelligence and experimentation, working together to decide how every parcel gets delivered. You'll lead causal inference at Relay from the start.
