Senior Machine Learning Engineer

At GSK we see a world in which advanced applications of Machine Learning and AI will allow us to develop novel therapies and respond to emerging or changing diseases with personalized drugs. We are looking for an accomplished Senior Machine Learning Engineer to help make this vision a reality. You will work with foundational genomics models and multiomics datasets to model aspects of RNA biology that inform the molecular mechanisms of diseases, drug response, and design of best-in-class drugs in a new therapeutic modality. Familiarity with genomics and RNA biology is a plus, but not required.

Competitive candidates will have a track record of shipping high performing machine learning powered products in production environments. They are accomplished ML engineers with breadth across ML methods and depth in at least one area, and experienced software engineers with a track record of shipping stable, tested, performant code and services in an agile environment. A senior engineer can translate poorly defined problems into clear objectives and execute to build high performing products or services, serving as a model for code quality, standards, and best practices and mentoring junior team members.

Strong candidates will have graduate studies in Computer Science, Applied Mathematics, or equivalent (or life sciences with a focus on ML techniques) and 3+ years of industry experience building ML powered tools. Educational or professional background in biological sciences is a plus but not necessary. The AI/ML team emphasizes ownership, accountability, continuous development, and collaboration. We hire for the long term and are committed to your career and development from day one.
