Job summary

Epic Games is seeking a Machine Learning Engineer focused on memory to advance memory-driven models across our Unreal Engine and platform ecosystem. You will collaborate with researchers to define general memory solutions, decide what to retain or discard, and build robust, scalable systems that store, retrieve and exploit experience effectively.

Ideal candidates have a PhD or 3+ years in industry with ML work on memory, context, or long-horizon methods, plus strong Python and ML tooling skills

Qualifications

• PhD in Computer Science, Mathematics or related field or 3+ years of relevant industry experience.
• Experience creating machine learning algorithms for vision and/or language problems and deploying them as production-level systems.
• Expert, hands-on knowledge of foundational models and vision and/or language, incl. local deployment and model post-training of open weights models.
• Memory, state, or long-horizon behaviour in foundation models: from language agents to long-context methods and sequence modelling.
• Python and associated ML tools/frameworks (numpy, scipy, sklearn, pytorch).
• Experience collaborating with other developers in a flexible, agile environment.

Responsibilities

• Design memory architectures that work across problems, modalities and products.
• Define new metrics to measure memory performance.
• Deliver production-ready, scalable learning models and guiding algorithms.
• Assess effectiveness and provide recommendations for the product roadmap.

WHAT MAKES US EPIC?

At the core of Epic's success are talented, passionate people. Epic prides itself on creating a collaborative, welcoming, and creative environment. Whether it's building award-winning games or crafting engine technology that enables others to make visually stunning interactive experiences, we're always Epic means being a part of a team that continually strives to do right by our community and users. We're constantly innovating to raise the bar of engine and game development.

ENGINEERING - GAMES

What We Do

Unreal projects have been leading the pack of real-time entertainment with our constantly growing team of engineering experts. We're always improving on the tools and technology that empower content developers worldwide.

What You'll Do

As foundation models move from answering questions to acting over long horizons, memory becomes a central requirement. Systems must decide what is worth keeping and improve from experience. Large context windows and retrieval systems are not enough. You will work with researchers on projects across the company that require memory in different modalities to define general solutions that enable models to represent experience, decide what they keep and what they discard, and to efficiently store, retrieve and exploit memory.

In this role, you will:

• Design new memory architectures that work across problems, modalities and products
• Define new ways to measure and evaluate memory performance
• Help create and deliver production-ready, scalable and high-quality learning models and associated algorithms
• Critically assess the effectiveness of such models and make recommendations for the ongoing roadmap

What we’re looking for

• PhD in Computer Science, Mathematics or related field, or 3+ years of relevant industry experience
• Experience creating machine learning algorithms for vision and/or language problems and deploying them as production-level systems
• Expert, hands‑on knowledge of: Foundational models and vision and/or language, incl. local deployment and model post‑training of open weights models
• Memory, state, or long‑horizon behaviour in foundation models: your experience may come from language agents and long‑context methods, reinforcement learning under partial observability, world models, or sequence modelling
• Python and associated ML tools/frameworks (numpy, scipy, sklearn, pytorch)
• Experience with working collaboratively with other developers, following a flexible and agile approach
