Top Tech Jobs & Startup Jobs in Montreal

Own the quality strategy for Unity’s Android platform support across mobile, laptop, and hybrid devices. Develop test plans, automated and exploratory test suites, performance benchmarks, monitoring dashboards, and platform coverage. Analyze bugs and regressions, convert reports into automated tests, collaborate with automation teams and external partners, and validate runtime optimizations. The role requires Android testing, C# automation, performance profiling, complex software delivery, and familiarity with graphics performance and game engines.

Develop platform support for Unity across Android mobile, laptop, and hybrid devices. Design scalable editor features, analyze and optimize runtime performance, establish benchmarks, resolve bugs, document technical designs, and improve quality through automated testing and code reviews. The role requires advanced C++, C#, and Android systems programming, experience with platform or runtime systems, multithreaded codebases, cross-language memory management, debugging, profiling, and collaboration across engineering teams.

Leads cross-functional platform engineering initiatives supporting Unity on Android devices. Designs architectures, optimizes runtime performance, establishes benchmarks, resolves complex system-level issues, mentors engineers, contributes to platform roadmaps, documents technical decisions, and participates in design reviews. The role requires advanced C++, C#, and Android systems programming expertise, strong knowledge of computer architecture, multithreading, debugging, profiling, and large-scale platform or runtime systems.

Design and scale AI agent systems in Unity for goal-directed behavior, planning, decision-making, and persistent world modeling. Develop reusable agentic frameworks and ML models, optimize real-time performance, and lead reinforcement learning, NPC planning, and agent memory initiatives. Establish model evaluation and AI safety practices, collaborate across teams, contribute to product strategy, and mentor engineers and researchers.

Design and deliver scalable cloud services and full-stack features for a next-generation game creation platform. Optimize cloud applications, apply service architecture patterns, use agentic AI tools such as Claude Code, and manage CI/CD, monitoring, and database maintenance. The role also drives technical direction, aligns with leadership, and collaborates with AI, infrastructure, and data teams.

Design, build, and operate scalable, low-latency backend services and distributed inference systems for internal AI tooling. Architect core services for agent orchestration, manage GCP infrastructure and Kubernetes workloads, implement observability with Prometheus/Grafana, and drive DevOps/SRE best practices across teams.

Join Unity's Monetization team in Montreal to design, implement, test, and improve the Unity Mediation SDK and extend the Unity engine. Own feature lifecycles, write scalable high-quality code and automated tests, mentor teammates, collaborate with distributed cross-functional teams, and build tools (including AI-driven) to enhance developer productivity and monetization capabilities.

Lead end-to-end design and implementation of Diagnostics backend: high-throughput Go services, ingestion and OpenTelemetry pipelines, ClickHouse-based storage and queries, and dashboard surfaces. Collaborate cross-team, mentor engineers, raise code-review and AI-agent workflow standards, and ensure reliability, performance, and secure data handling.
