ERLPhase Power Technologies Ltd.

Machine Learning Engineer

• Own critical part of ML: productionising of our models end-to-end, from training pipeline through live integration to measured business impact.
• Build and mature our ML Platform. Evolve the model serving architecture, expand reusable components adoption and set the standards for how Relay ships ML org-wide.
• Strengthen existing models by architecting integration and system testing within training pipelines, automated releases and drift monitoring.
• Launch completely revamped processes side by side with data scientists and measure their real-world impact on the network.

• To experiment and measure the impact of model improvements or pricing strategy changes.

Senior Data Scientist – Last Mile Pricing

Data Analyst

• 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're hiring for 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's a v1 of performance management already running; you'll 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'll run the experiments, design the measurement, and quantify what actually works.
• The job now 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'll 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'll think about how performance and rewards are made transparent to them, and you'll run experiments to evaluate whether interventions are actually working for couriers and for Relay.

Senior Data Analyst – Last Mile

• Track forecast accuracy across all Network models: demand forecasts, shift planning forecasts, dimensions model, BPP inclusion models
• Surface model drift and performance issues before they impact operations - you're the early warning system
• Diagnose forecast errors by client, geography, day of week, and horizon, and quantify the CPP impact
• Build dashboards that make model performance transparent to the squad and stakeholders
• Set analytical direction for the Network squad: define what metrics matter, where to invest analytical effort
• Work with Data Scientists to build the business case for model improvements, whether that's new input signals, data quality fixes, or client-specific treatment
• Monitor how capacity matches demand across Sortation, Middle Mile, Last Mile, and track shift release effectiveness
• Translate model performance into business impact that stakeholders can act on
