Overview

Relay’s Last Mile network runs on couriers — tens of thousands of them, doing real work in the physical world every day. Whether each parcel gets delivered successfully depends on the decisions and behaviours of the courier on route. We are hiring a Senior Data Analyst to own how Relay measures and improves courier excellence: how we shape what happens on the doorstep, and how we manage performance before and after that interaction. This role works with the whole of the Last Mile team and partners closely with data scientists, engineers and operators across the squad. There is a v1 of performance management already running; you will own its evolution into something materially better. Your job is to make those trade-offs visible, model them, and find the levers that move the network in the right direction. You will run the experiments, design the measurement, and quantify what actually works. The role is to ensure it drives fleet quality — defining the right behaviours to measure, evaluating the interventions designed to help couriers shift those behaviours, and closing the loop so the framework continuously improves. You will partner with product, ops and engineering across this work, with the analytics owned by you. Couriers are the end users of much of this work. You will consider how performance and rewards are made transparent to them, and you will run experiments to evaluate whether interventions are actually working for couriers and for Relay.

Responsibilities

  • Own how Relay measures and improves courier excellence, shaping what happens on the doorstep and managing performance before and after interaction.
  • Collaborate with the Last Mile team and partners across data science, engineering and operations to evolve performance management.
  • Model trade-offs, run experiments, design measurement, and quantify what works to move the network in the right direction.
  • Ensure the framework drives fleet quality by defining the right behaviours to measure and evaluating interventions that shift those behaviours.
  • Partner with product, operations and engineering; own the analytics for this work.
  • Consider couriers as end users; simplify transparency of performance and rewards and test interventions for effectiveness for couriers and Relay.

Requirements

  • You’re a strong analyst who thinks in systems, breaking complex problems into components to identify real opportunities.
  • You can operate with high autonomy and define and execute a roadmap in a Product/Programme Manager-like capacity.
  • You care about solving the problem more than which techniques you use.
  • You enjoy working with smart, motivated people.
  • You’re fluent in SQL.
  • You’re comfortable across the analytical spectrum—designing and reading experiments, building risk scores and segmentation, and shipping descriptive analysis that informs a decision within the same week.
  • You communicate inclusively with non-technical team members.
  • You enjoy seeing the impact of your work in daily operations.
  • Bonus: Experience in performance management, marketplace quality, operational analytics, or a related domain.
