Research Scientist, Causal Inference

Relay is fundamentally reshaping how goods move in an online era. Backed by Europe’s largest-ever logistics Series A ($35M) led by deep-tech investors Plural, and a recently closed Series B ($95M), Relay is scaling faster than 99% of venture-backed startups.

As a Research Scientist at Relay, you'll lead causal inference at Relay from the start. You'll set the standard for causal inference, measure how Relay's decisions affect each courier, shape how Relay experiments across a live, two-sided marketplace, adapt advanced techniques across causal inference, statistics, and machine learning to Relay's problems, and partner with Operational Research to embed your insights and models into Relay's network-wide optimisation.

Responsibilities:

• Set the standard for causal inference at Relay.
• Measure how Relay's decisions affect each courier, today and over time.
• Shape how Relay experiments across a live, two-sided marketplace.
• Adapt advanced techniques across causal inference, statistics, and machine learning to Relay's problems, and see them through to production.
• Partner with Operational Research to embed your insights and models into Relay's network-wide optimisation, and help build Relay's research culture and voice in the tech community.

Requirements:

• Deep expertise in causal inference, experimentation, and machine learning.
• Experience applying advanced techniques to real marketplaces or products.
• Strong technical fundamentals and entrepreneurial drive.
