Top Tech Jobs & Startup Jobs in Montreal

Paid 6–12 month research internship developing and experimenting with ML models (vision, NLP, speech) for game agents, player safety, content generation, and developer tools. Tasks include data creation/analysis, end-to-end model design and prototyping, and collaborating with research scientists and engineers to deploy models.

Design and ship end-to-end AI systems integrated with Unreal Engine, including C++ and Python engine tooling, cloud-hosted agent services, databases, and web interfaces. Build LLM-driven agents, evaluate emerging capabilities such as tool use and multi-agent orchestration, and define reliability, safety, and evaluation standards. Collaborate with engine, tools, and backend teams while mentoring programmers.

Leads Rocket League gameplay programming teams, translating feature requests into actionable work, delegating tasks, delivering gameplay systems, and writing or reviewing C++ code. Oversees technical design, gameplay physics, network replication, and system integration while collaborating with design, art, production, and other programming teams. Requires leadership on shipped AAA Unreal Engine games and experience using AI coding assistants.

Lead narrative design for Fortnite and other game IPs by executing story vision, developing characters and worlds, writing storylines and dialogue, integrating narrative with gameplay and art, reviewing writing processes, and coordinating casting and voice recording. The role partners with creative, design, art, production, and writing teams to deliver cohesive, immersive storytelling experiences.

Develop and optimize mobile platform technologies for Fortnite and Unreal Engine across Android and iOS. Build low-level systems interfacing with memory, file, input, graphics, and shader APIs; improve toolchains, deployment, debugging, crash reporting, and platform support. Collaborate with engineering and content teams to resolve performance, stability, memory, and load-time issues while supporting new mobile hardware.

Develop and maintain core gameplay features and systems for Unreal Engine projects, including player mechanics, abilities, progression, vehicles, game flow, and world systems. Collaborate with designers, artists, animators, and other programmers; diagnose gameplay, memory, performance, networking, and scalability issues; and deliver robust, maintainable code for multiplayer games across multiple platforms.

Build and maintain CI/CD pipelines and build automation for Rocket League. Collaborate with developers, QA, production, and infrastructure to improve workflows, monitor build health, troubleshoot failures, and support releases. Create tools to optimize developer productivity and ensure stable, scalable build systems during critical milestones.

Design, build, and maintain core AI gameplay systems for Fortnite. Collaborate with designers, artists, and engine teams to prototype and iterate AI features, optimize and fix bugs, and ensure high-quality cross-platform user experiences.

Design and evaluate memory architectures for foundation models across modalities; develop production-ready scalable learning models; define metrics for memory performance; collaborate with researchers and engineers to roadmap and deploy memory-enabled systems.

Develop Unreal Editor features that integrate cloud-based collaboration, version control, and distributed workflows. Build responsive editor experiences interacting with asynchronous networked services, collaborate with product/UX/backend teams, and implement resilient, low-latency systems that improve creator workflows.
