Why churn prediction matters We partner with thousands of restaurants across our markets to bring our customers an unbeatable selection of food and cuisines. We work hard to find and onboard new restaurants to our platform to improve the customer choice and experience. However, onboarding efforts would be wasted if existing partners were to leave, an event we refer to as churn. We expect there to be some natural level of churn. A restaurant might see low demand because of an adverse economic environment, or the restaurant might be too busy serving on-site customers. Or perhaps the restaurant…
Over the past two years, we’ve witnessed a Cambrian explosion of AI development, with Generative and Agentic AI capturing stakeholders’ attention. AI/ML Engineers are delivering real business value by intermixing LLMs and agentic systems with traditional machine learning systems. It’s been an era of rapid prototyping and quick integrations. Teams have adopted different approaches - each unlocking new potential, but also introducing complexity. As these prototypes evolved into production systems, duplicated effort and inefficiencies began to show. Teams built similar observability and…
LLMs, MCPs, RAG. There are lots of acronyms in the AI space, but what do they all mean? Dear reader, despite being a software engineer who works in the machine learning space, I confess there was a time I wasn’t really sure. Fortunately, with the financial support of Deliveroo’s Women-in-Tech Employee Resource Group, I took the Ardan Labs Building AI-Powered Applications in Go workshop that helped me understand what’s really going on behind the chat interface and where software engineering meets LLM-based applications. We went through a series of modules to incrementally build a RAG…
Hey everyone, I’m Kartik Visvanathan, an Engineering Manager at Deliveroo, based in India. I joined the team in 2023, and it’s been an exciting ride ever since. I’ve built some truly impactful products here, including an advertising platform that we scaled into a profitable business, and a corporate orders product that touched every part of our systems—from restaurants to delivery to customer service. But while building cool stuff is awesome, what I really want to share today is the secret sauce behind it: how we work as a team here in India. A Truly Global Hub Our engineering hub in India is…
At Deliveroo, we’re always refining how we scale - especially when it comes to managing compute costs in the cloud. After optimising our Amazon ECS workloads with Reserved Instances and Savings Plans, we saw an opportunity to push further using EC2 Spot Instances, which offer up to 90% savings compared to On-Demand prices. But Spot comes with challenges: Their availability can fluctuate, and they can be terminated with just a two-minute warning. To unlock these savings without compromising service stability, we had to engineer a robust solution across infrastructure, workload qualification,…
Enter Deliveroo’s ML Platform For the past three years, we have been building Deliveroo’s Machine Learning Platform, or the ML Platform as we like to call it. The ML Platform boosts our model-building and deployment capabilities by standardising ML workflows, streamlining the end-to-end development process and simplifying model deployment. Besides saving software engineering effort through centralising tooling, the ML Platform also reduces the time that our ML engineers spend on infrastructure tasks. As a result, our ML engineers can now iterate their ML models 2-3x faster than before. What…
Could you introduce yourself and your role at Deliveroo? I’m Antonio, a Senior Staff Engineer at Deliveroo. I have been with Deliveroo for six and a half years, overseeing the entire New Verticals domain as well as the Catalogues space, as an Individual Contributor (IC). Can you tell us a little bit about your career journey into engineering and how you found yourself at Deliveroo? I have been passionate about computers since childhood, which led me to pursue studies in software engineering. I began my career working for consultancy firms in Italy, my home country, before moving to London,…
The Women in Tech Employee Resource Group (ERG) at Deliveroo was officially founded in 2023, and we are proud to represent an amazing community of female employees who identify as working in Tech at Deliveroo. This includes, but is not limited to, Software Engineers, Data Scientists, Designers, and Product Managers and we also welcome those who want to move into a Tech role. We host many events and initiatives throughout the year that align with our mission to connect and empower women in technology to excel in their careers at Deliveroo and beyond. For our main end-of-year event, we chose to…
Could you introduce yourself and your role at Deliveroo? I’m Gina, I’m a Senior Engineering Manager at Deliveroo. I lead our Consumer Experience group in our New Verticals engineering team, and I’ve been at Deliveroo for five years. Could you walk us through your path to engineering management and what brought you to Deliveroo? I studied information systems at university and developed an interest in human-computer interaction. This field emphasises understanding users and translating business processes into technical requirements. I moved to San Francisco for a tech consulting role, where I…
Experimentation at Deliveroo has significantly boosted our innovation as a company. It has allowed us to explore new ideas, protected us from unforeseen challenges by preventing wasted time and resources on ineffective initiatives, and promoted intellectual honesty by validating our assumptions. Over time, the breadth of our experimentation programme, our tooling and our culture have undergone significant development. Each year, we run hundreds of experiments, testing a wide array of features. These experiments range from simple UI modifications to complex algorithm adjustments. We employ a…
