Senior Decision Scientist, Partner Excellence

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 Senior Decision Scientist, Partner Excellence at Relay, you'll decide which Partner Excellence problems are real and which only look real, before anyone builds a fix. You'll design how Partner Excellence decides: which signals count, what evidence the network runs on, and what good looks like.

Responsibilities:

• Decide which Partner Excellence problems are real and which only look real
• Design how Partner Excellence decides: which signals count, what evidence the network runs on, and what good looks like
• Tell the squad lead what to change and what to stop, and get a decision
• Build the thing that decides: data applications, monitors and alerts, not decks, using Claude and agents to ship your own tools
• Go and look when the data and the street disagree: the sort centre, the van, the shop
• Get the missing data built, and prove which fixes worked

Requirements:

• Have owned fraud, risk or trust decisions end to end: turned investigations into rules, standards or interventions, and owned their number
• Have run investigations in fraud, risk, financial crime or trust and safety, and decided whether a signal was real or noise
• Have seen their work acted on: a leader changed a plan, a team adopted your method, or engineers built what you asked for
• Have worked somewhere with enough volume for a false positive rate to mean something
• Are hands-on and fluent in SQL, with or without AI
