Job description

The Opportunity

We are looking for a Senior Back End Engineer to architect and build the robust, backend platform that transforms Stellar’s Gen AI software from an internal prototype into a professional, commercial-grade solution for the global animation and VFX industry. You will not just be writing code; you will bridge high-performance AI workflows and a secure, artist-centric user experience, ensuring reliability, auditability, and scalability for customers.

Key Accountabilities (What you will own)

Platform Architecture & Containerization

• From Prototype to Product: Lead the migration of our current local prototype into a robust, scalable, containerized cloud environment.
• Deployment: Work with the Product Manager to deploy application code and manage data storage strategies that scale as our user base grows.
• Documentation: Maintain clear API and backend documentation to keep the system maintainable as the engineering team expands.

AI Infrastructure & GPU Optimization

• Worker Nodes: Configure and optimize GPU-accelerated worker nodes to handle high-performance ComfyUI workloads with minimal latency.
• Monitoring: Set up system monitoring and alerting (Grafana/Prometheus) to track worker health, GPU usage, and real-time performance.

Security, Identity & Data Segregation

• Multi-Tenancy: Build security layers for user login and strict data separation between clients.
• Asset Security: Implement secure, high-speed storage for 2D image sequences and metadata.

Auditability & Integration

• Chain-of-Title: Enable full auditability with an immutable database and ensure every generated image has a traceable history for legal and copyright compliance.
• DCC Integration: Collaborate to optimize REST API performance, ensuring seamless communication between backend and creative tools like Maya and Blender.

The Requirements

Must-Haves:

• 5+ years in Back End Engineering or Platform Engineering.
• Expert proficiency in Python (essential for AI/ComfyUI integration).
• Strong experience with Docker and Kubernetes for orchestration.
• Proven ability to design and optimize RESTful APIs for high-load environments.
• Experience designing multi-tenant architectures (Auth0/OAuth, data segregation).
• Legally entitled to work in Canada.

Nice-to-Haves:

• Experience with ComfyUI or Stable Diffusion workflows.
• Knowledge of immutable ledgers or databases (for chain-of-title tracking).
• Background in VFX, Animation, or handling large media assets.

Why Join Stellar?

• Hybrid Work: Flexible schedule with 2-3 days in our Vancouver office.
• Comprehensive Benefits: Extended health, dental, and vision coverage.
• Growth: Professional development support to stay ahead of tech trends.
• Culture: A collaborative, ego-free environment where technical expertise fuels creative magic.
