Design jobs in Canada

Boldly built for every fandom, Tubi is a free streaming service that entertains over 100 million monthly active users. Tubi offers the world's largest collection of Hollywood movies and TV shows, thousands of creator‑led stories and hundreds of Tubi Originals made for the most passionate fans. Headquartered in San Francisco and founded in 2014, Tubi is part of Tubi Media Group, a division of Fox Corporation.

Tubi's Core Experience Backend team is responsible for building the high‑performance, secure, and scalable systems that power our business. We have built disaster‑resilient systems to ensure Tubi APIs continue to perform even under extreme traffic conditions. Our team and services have delivered seamless operations for massive events such as the Super Bowl and World Cup while consistently delivering a great experience to our viewers.

On this team, you will participate in major campaigns, contribute to our critical backend services, support multiple platforms, and play a key role in shaping and refining the overall backend architecture.

This is a hybrid role based out of our Toronto office. You must be willing to travel to our Toronto office three days per week.

• Design and implement high‑performance backend services in Elixir
• Architect and evolve microservices and distributed systems in Kubernetes
• Optimize systems for scale, resilience, observability, and security
• Collaborate with cross‑functional teams to deliver pragmatic solutions to complex problems
• Explore and integrate AI‑based development tools into daily workflows
• Work across service boundaries, own critical architecture/service design, and help evolve Tubi’s backend system

• Experience in Elixir or strong background in other backend or functional programming languages
• Familiarity with gRPC/Protocol Buffers, RESTful API design, Kubernetes, and observability solutions
• Experience designing distributed systems with clean APIs and modular components
• System design and architecture skills with emphasis on reliability and performance
• Experience with continuous delivery of software systems

• Rust programming experience
• Extensive experience with Elixir in production environments
• Familiarity with Pingora or Nginx
• Hands‑on experience with Kubernetes

This role goes beyond traditional engineering: you will extensively use AI to build the backend stack. The goal is to unlock smarter execution, faster delivery, and automation at scale, while ensuring responsible use of these technologies.

• AI‑Augmented Backend Development: Using AI‑assisted coding tools (Claude Code, Cursor, etc.) to accelerate development while maintaining rigorous standards for correctness, security, and performance. You will set the bar for how backend engineers harness AI to iterate faster, write safer code, and document systems more effectively.
• AI‑Enhanced Architecture & Optimization: Exploring how AI can assist in system design, performance tuning, and anomaly detection across Tubi’s distributed backend. You will prototype and integrate AI‑powered optimizations that improve throughput, reduce latency, and detect inefficiencies in large‑scale microservice architectures.
• AI‑Driven Developer Experience: Contributing to internal tools and platforms that use AI to improve the daily developer workflow, ranging from automated code reviews and test generation to smarter observability dashboards. You will help evolve Tubi’s backend development culture into an AI‑native practice.

• Flexible Work Policy and Remote Work Options
• Generous Paid Time Off and Parental Leave
• Opportunities for Career Growth and Professional Development
