Senior Data Scientist - Last Mile Pricing

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. We're assembling the most talent-dense team the logistics industry has ever seen.

Relay’s Mission is to free commerce from friction . Today, high delivery costs act as a hidden tax on e-commerce, quietly shaping what can be sold online and limiting who can participate. We envision a world where more goods move more freely between more people , making the online shopping experience seamless and accessible to everyone.

THE TEAM

• ~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

The opportunity

A last-mile marketplace runs on decisions - which parcels? on which routes? delivered by which couriers? at what price? Thousands of them, made every single day. Good decisions have fast and meaningful impact across the entire Relay Network. We’re hiring for a Senior Data Scientist to build the intelligence that informs and defines how we make pricing decisions at Relay. This is a senior individual contributor role. You will work alongside Operational Research Scientists, Analysts, and Engineers in a collaborative squad focussed on developing the intelligence, strategy and technology to deliver 1000’s of daily pricing decisions.

What You'll Do

You won’t just inform the pricing decisions, you will be an equal part of the team defining how the decision is being made and building the technology to automate it. In this role you can expect:

• Through your own investigation, to become an expert in Relay marketplace pricing dynamics, using it to define how routes are priced.
• To build and maintain production models that inform the daily pricing decisions.
• To experiment and measure the impact of model improvements or pricing strategy changes.

Who Will Thrive In This Role

• You're a strong modeller who thinks in systems.
• You care about solving the problem above all else
• You love working with smart, motivated people
• You’re fluent in python and SQL
• You communicate inclusively with non-technical team members
• You are successful working with high autonomy
• You love seeing the impact of your work play out in a daily operation
• You have experience modelling marketplace dynamics, pricing strategies or another relevant domain.

Compensation, Benefits & Workplace

• Generous equity, richer than 99% of European startups, with annual top-ups to share Relay’s success.
• Private health & dental coverage, so comprehensive you’d need to be a partner at a Magic Circle law firm to match it.
• 25 days of holidays
• Enhanced parental leave.
• Located in Shoreditch, our office set-up enables the kind of in-person interactions that drive impact. We work 4 days on-site, with 1 day remote.
• Hardware of your choice.
• Extensive perks (gym subsidies, cycle-to-work, Friday office lunch, covered Uber home and dinner for late nights, and more).

Who Thrives at Relay?

• Aim with Precision: You define problems clearly and measure your impact meticulously.
• Play to Win: You chase bold bets, tackle the hard stuff, and view constraints as fuel, not friction.
• 1% Better Every Day: You believe that small, consistent improvements lead to exponential growth. You move quickly, deliver results, and learn from every experience.
• All In, All the Time: You show up and step up. You take ownership from start to finish and do what it takes to deliver when it counts.
• People-Powered Greatness: You invest in your teammates. You give and receive feedback with care and candour. You build trust through high standards and shared success.
• Grow the Whole Pie: You seek out win‑win solutions for merchants, couriers, and our customers, because when they thrive, so do we.

If these resonate, and you combine strong technical fundamentals with entrepreneurial drive, let’s connect.

Relay is an equal-opportunity employer committed to diversity, inclusion, and fostering a workplace where everyone thrives.
