We are looking for a Senior Applied Scientist, with expertise in deep learning, to join our cross-functional Search and Recommendations team to help further the success of our recommender system. Our system plays a key role in helping ASOS provide the best shopping experience to our millions of customers by surfacing the right product to the right customer at the right time, handling up to 8000 requests per second at peak in production.  The whole team is responsible for the end-to-end system, and we are all accountable for making sure it performs in production, at the scale at which ASOS operates. 

The role sits within the Applied Science domain, which is responsible for the algorithms that power ASOS digital ecosystem. From Recommender Systems through to forecasting models that drive key operating decisions, the teams maintain, build and innovate in some of the most interesting areas of machine learning at scale, training models on unique datasets, transactions and clickstream data. 

What you’ll be doing: 

• You will be part of an agile, cross-functional team building and managing a large-scale recommender system, working with massive amounts of data, and delivering deep learning models into production.  
• You will be driving the implementation and scale-up of algorithms for measurable impact across the business and set up and conduct large-scale experiments to test hypotheses and drive product development. 
• You will be keeping up to date with relevant state-of-the-art research, taking part in reading groups alongside other scientists, with the opportunity to publish novel prototypes for the business at top conferences. 
• You will be continually developing and improving our code and technology, taking an active role in the conception of brand-new features for our millions of global customers.  
• You will be mentoring and coaching junior members of the team, supporting their technical progress. 
• You will take part in regular Tech Develops days to learn new things, take part in internal and external hackathons, and share your knowledge and help drive improvements in science and engineering. 
• You will support our culture by championing Diversity, Equity & Inclusion strategies. 

About You

• You are an experienced Applied Scientist with hands on experience of building recommender systems or a track record of using state of the art deep learning methods to solve complex business problems
• Will have some knowledge or experience of working in retail, marketing, or the ecommerce industry. You thrive in working in a cross-functional platform, including scientists, engineers, and non-technical stakeholders.
• You are comfortable working in Python software stacks and familiar with at least one deep learning framework (such as TensorFlow/Keras and PyTorch) and enjoy going from ideas and prototypes into products and applications.  
• You have a solid understanding of software development lifecycles and engineering practices, alongside a good understanding of ML and statistics.  
• You will be comfortable providing technical leadership, mentoring, and coaching to a motivated development team. 
• We would love to meet someone who has authored publications in top-tier machine learning conferences or journals (such as NeurIPS, ICLR, ICML, KDD, CVPR, ICCV, ECCV, ACL, EMNLP) and want to keep up to date with the state of the art.
