Senior Machine Learning Engineer

Salary: £135,000 - 175,000 per year

Requirements:

• We require a PhD in Computer Science, Mathematics, or a related field, or 3+ years of relevant industry experience.
• We are looking for experience creating and applying machine learning algorithms for bot action modeling, including vision-based or language-instructed systems, and deploying them as production-level in-game systems.
• We need expert, hands-on knowledge of deep learning, including applications in the gaming industry.
• We need experience with foundational models and vision and/or language, especially vision-language-action models and reinforcement learning agents, including local deployment and post-training of open-weights models.
• We need experience in reinforcement learning, including agentic systems, reward design, policy optimisation, evaluation, and building scalable training environments for agents.
• We need strong Python skills and experience with ML tools and frameworks such as numpy, scipy, sklearn, and pytorch.
• We value experience working collaboratively with other developers in a flexible, agile, or lean environment.

Responsibilities:

• We work with applied research engineers at the intersection of computer vision, gameplay agents, natural language processing, and machine learning to create state-of-the-art tools for game developers.
• We focus on bots, including trained gameplay agents, intelligent NPCs, companions, and world modeling, as well as automation across moderation, security, and QA testing.
• We design, implement, and deploy production-ready machine learning models that can be integrated into our ecosystem.
• We create and deliver scalable, high-quality machine learning models and associated algorithms that can make actions in game environments.
• We critically assess model effectiveness and make recommendations for the ongoing roadmap.
• We methodically understand and evaluate new data channels and support the collection and creation of new ones.
