We're a fast-growing, founder-led start-up, passionate about making digital ads work better for everyone. Now, we're looking for our first ever Applied Machine Learning Engineer to help us build intelligent systems that power the future of digital advertising. What will you be doing as an Applied Machine Learning Engineer? <ul> <li>Build applied ML systems that make our product smarter and more defensible</li> <li>Develop contextual categorisation of web content (e.g. automatically recognising industry categories)</li> <li>Prototype algorithms that can improve advertising outcomes, such as smarter bidding or optimisation logic</li> <li>Work closely with product and commercial teams to package outputs into demos and case studies for clients</li> <li>Collaborate with engineers to integrate ML features into production system</li> <li>Establish good practices for applied ML in the business, bringing your curiosity and drive to help us move fast while building robust foundations</li> <li>Apply modern LLM techniques to business problems: <ul> <li>Use prompt-engineering strategies to get consistent, accurate results</li> <li>Explore augmentation methods (e.g. combining LLMs with our own data via embeddings or retrieval)</li> <li>Run fine-tuning experiments to adapt general models to our specific domain</li> </ul> </li> </ul> Who are we looking for? We're looking for someone who is curious, hands-on and eager to shape the future of Machine Learning at Picnic.

You'll be part of a culture that's grounded in our values and pushes us forward every day: <ul> <li>You're trusted to take ownership, make decisions and deliver with autonomy</li> <li>Ideas move quickly from concept to reality - we learn by doing, not over-polishing</li> <li>We constantly push ourselves and the industry forward, aiming higher with every piece of work</li> </ul> Together, these values guide us as we tackle hard problems, learn fast and make digital ads better What can Picnic offer you? We're proud to have been recognised by Culture100 and Flexa as one of the best and most flexible small businesses to work for.
