Engine Programmer Internship

London, United Kingdom
2026-09-03

Role Description

**Description** We are looking for an Engine Programmer Intern to join the team building a new serialization stack for Unreal Engine. This schema-based serialization system will be at the heart of how engine content is saved, loaded, and versioned. As part of the serialization team, you will be given a feature to own within our development cycle — such as schema evolution, data migration/recovery, type bindings, or debug tooling. You will work with your engineering lead and partner-teams across the engine to flesh out the system and build core technology that millions of players and creators rely on every day. **Responsibilities** * Design and implement a feature within the serialization stack, taking it from proposal to shipped code with guidance from your engineering lead. * Write high-performance, memory-efficient C\+\+ for systems where correctness and backwards compatibility are critical. * Build tooling that helps users work with serialized data — such as diffing, visualization, and human-readable text formats. * Develop thorough unit tests to guarantee data integrity across save, load, and version-upgrade paths. * Collaborate with partner teams across the engine to integrate the serialization system with their data and workflows. * Participate in code reviews and design discussions, learning how core engine technology is built and maintained at scale. **Qualifications** * Strong C\+\+ fundamentals, including a solid grasp of memory management, pointers, and familiarity with the fundamentals of template. * Self-driven, eager to learn, and open to feedback, using it to improve your work. * Interest in low-level systems programming — file formats, binary data, compilers, or engine internals. * A rigorous, detail-oriented approach. * Good understanding of data structures and how data is laid out and represented in memory. * Comfortable debugging unfamiliar code and methodically tracking down the root cause of a problem. * Ability to explain a technical design and ask good questions.
