Job description

Overview

Relay is fundamentally reshaping how goods move in an online era. Relay is backed by Europe’s largest-ever logistics Series A ($35M) and is scaling rapidly. We are assembling a talent-dense team across engineering, product and data to move more goods more freely and reduce delivery costs that act as a hidden tax on e-commerce.

The Team

• ~90 people, more than 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 parcel

• An intellectually vibrant culture of first-principles thinking, tight feedback loops and relentless experimentation

Work Alongside Industry Leaders

Andy Turner – Director of Data

Andy Turner has built and led data teams across global enterprises and high-growth scale-ups on five continents. He has delivered cloud-native platforms, launched AI products end to end, and holds patents for novel machine learning applications in the UK Capital Markets. Trained in statistics at Oxford, he pairs strong technical fundamentals with clear judgement, a commercial focus, and a bias to deliver.

Tech Stack Highlights

• Cloud-native on GCP with extensive use of BigQuery and Cloud Run

• Extensive use of ML modelling and LLM inference

• Python, Rust and TypeScript

• Cross-platform Flutter apps with focus on user experience

• Emerging tech integrations, including robotics and IoT-powered operations

The Opportunity

As a Lead Data Analyst, you’ll go beyond reporting—building frameworks, models and analytical systems that drive Relay’s most critical decisions. From real-time dashboards that keep thousands of couriers moving to simulations of expansion across cities and countries, you’ll transform raw data into foundations for strategy and execution.

You’ll own projects end-to-end: defining the problem, building analytical assets (dbt models, BigQuery pipelines, Python simulations), and delivering recommendations that shape Relay’s network.

Example Projects

• Pitstop & Middle Mile Optimisation: Design a monitoring framework for courier shifts, integrating geo-signals, operational data and predictive models to keep the network balanced and efficient.

• Geo-Expansion Strategy: Build decision frameworks combining internal performance data with external commercial and demographic signals to determine where to grow next and model unit economics.

• Courier Marketplace Analytics: Run live experiments and causal inference models to optimise how couriers discover and book routes, improving match quality and efficiency.

What You’ll Do

• Design, own and scale core analytical models in dbt/BigQuery, ensuring robust, performant and transparent decision-making foundations.

• Build and maintain dashboards and data tools that translate millions of daily signals into actionable intelligence.

• Partner with engineers, operators and product managers to shape strategy through evidence-driven recommendations.

• Develop and run experiments, simulations and scenario models to guide Relay’s operational and commercial bets.

• Spend time embedded in operational processes to ensure solutions reflect on-the-ground reality.

Hiring Process

1. Talent Acquisition Interview - 30mins

2. Hiring Manager Discussion - 45mins

3. SQL Live Coding - 60mins

4. Case Study - 60mins

Who Thrives at Relay?

• Aim with Precision: You define problems clearly and measure impact meticulously.

• Play to Win: You chase bold bets, tackle hard stuff, and view constraints as fuel.

• 1% Better Every Day: You move quickly, deliver results and learn from every experience.

• All In, All the Time: You take ownership from start to finish and do what it takes to deliver when it counts.

• People-Powered Greatness: You invest in teammates, give and receive feedback with candour, and build trust.

• Grow the Whole Pie: You seek win-win solutions for merchants, couriers and customers.
