Job description

Location: Montréal, Quebec

Our client is building an advanced real‑time AI + game streaming platform, designed to run massive distributed workloads at scale with ultra‑low latency. Their mission is to unlock a new generation of edge‑based applications powered by GPU acceleration and intelligent orchestration.

They are seeking a Senior C++ Engineer to help design and scale mission‑critical, real‑time systems. You’ll own performance‑sensitive components across rendering, compute, streaming, and orchestration — and play a central role in scaling the platform to production.

Note: This is an in‑office role. Must be willing and able to go in office 5 days/week.

Responsibilities

• Architect and implement high‑performance, low‑latency systems
• Optimize and evolve core platform modules for scalability and reliability
• Contribute to overall system architecture and component integration
• Profile and optimize performance‑critical code
• Write clean, well‑documented technical specs
• Evaluate tools and technologies to improve platform performance and developer experience
• Partner with cross‑functional engineering teams on delivery
• Support platform operations and participate in on‑call as needed

Must Have Skills

• 8+ years of hands‑on software development, with deep expertise in C++
• Experience with real‑time, low‑latency, or performance‑critical systems
• Strong understanding of Linux internals, drivers, or kernel‑level operations
• Exposure to GPU workloads and drivers (NVIDIA / AMD)
• Experience with graphics or compute APIs like OpenGL, Vulkan, DirectX, or Metal
• Familiarity with Docker, Kubernetes, and containerized infrastructure
• Experience with MySQL, MongoDB, and scalable database architecture
• Comfortable working across both backend and (optionally) frontend stacks

Nice to Have Skills

• Exposure to Node.js, React, Redux, or front‑end systems
• Experience in gaming, media streaming, or GPU‑accelerated applications
• Track record in startup environments or fast‑moving product teams
