Engine​/Gameplay Architect - UGC ​/ Architecte moteur ​/ gameplay – UGC

Job Summary

We’re looking for an Engine / Gameplay Architect to shape the foundation of user-generated content (UGC) on a large-scale AAA experience built in Unreal Engine.

• Architect the end-to-end UGC framework: data models, runtime systems, and extensibility points
• Design and evolve APIs that expose gameplay systems safely and flexibly to creators
• Define the scripting model (language, runtime) for user-authored content
• Partner with AI/ML teams to enable an AI agent that can generate, modify, and reason about gameplay content
• Establish guardrails: performance budgets, sandboxing, security, and determinism
• Work closely with gameplay, online, and tools teams to ensure cohesion across the platform
• Drive technical direction through prototypes, documentation, and hands‑on implementation
• Mentor engineers and influence engineering standards across teams

• Strong experience architecting gameplay or engine systems in C++ within Unreal Engine (or comparable AAA engines)
• Proven experience designing extensible systems, SDKs, or developer platforms used by internal or external creators
• Deep understanding of gameplay architecture, including:
  • Entity Component Systems (ECS) or actor-based models
  • Event‑driven architecture / messaging systems
  • State machines, replication models, and serialization pipelines
• Experience designing and maintaining APIs (C++, REST, or RPC) with a focus on usability, versioning, and backward compatibility
• Hands‑on experience with scripting languages and runtimes (e.g., Lua, Python, visual scripting like Blueprints, Verse, or custom DSLs)
• Familiarity with embedding scripting languages and bridging native and managed/runtime code
• Strong understanding of runtime performance optimization (CPU/GPU constraints, memory management, streaming systems, multithreading, async workflows)
• Experience working with large‑scale systems (open worlds, World Partitioning, asset streaming, networked/multiplayer environments)
• Knowledge of build systems, CI/CD pipelines, and content validation workflows
• Experience with sandboxing, capability‑based security, or safe execution environments for user‑authored code
• Comfort working across boundaries: engine, gameplay, backend services, and tools

• Experience building or supporting modding or UGC platforms (e.g., level editors, scripting APIs, creator tool chains)
• Exposure to AI/ML‑assisted development workflows, including:
  • LLM‑powered tools
  • Agent‑based systems
  • Prompt‑driven or natural language interfaces for content creation
• Familiarity with knowledge representation, graph‑based systems, or tool chains that enable AI reasoning over game data
• Experience with cloud‑integrated game platforms, backend services, or live service ecosystems
• Background in developer experience (Dev Ex), including tooling, documentation systems, and usability of technical platforms
• Experience designing for other developers, not just for systems
• Ability to balance flexibility with guardrails (power without chaos)
• Comfort making foundational decisions with long‑term impact
• Emphasis on usability as much as technical elegance
• Preference for simple mental models, even when systems are complex under the hood

• Interested candidates must apply to be considered.
• Work in our Montreal office a minimum of 4 days a week.
• Willing to work overtime when required, in accordance with Quebec labor standards.
• Legally authorized to work in Canada.
• Willing to travel for work‑related business if necessary.

Montreal, Quebec, Canada
