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 be the bridge between high-performance AI workflows and a secure, artist-centric user experience. Your work ensures that the software delivers the reliability, auditability, and scalability required by 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 closely with the Product Manager to deploy application code and manage data storage strategies that scale as our user base grows.
- Documentation: Maintain clear documentation for API and backend components to ensure the system remains 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 without latency.
- Monitoring: Set up system monitoring and alerting (using tools like Grafana/Prometheus) to track worker health, GPU usage, and system performance in real-time.
Security, Identity & Data Segregation
- Multi-Tenancy: Build the security layer that handles user login and ensures strict data separation between clients.
- Asset Security: Implement secure, high-speed storage solutions for 2D image sequences and metadata.
Auditability & Integration
- Chain-of-Title: Enable full auditability by implementing an immutable database. You will ensure every generated image has a traceable history for legal and copyright compliance.
- DCC Integration: Collaborate with software engineers to optimize REST API performance, ensuring seamless communication between our backend and creative tools like Maya and Blender.
The RequirementsMust-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 specifically 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: We offer a flexible schedule with 2-3 days in our Vancouver office.
- Comprehensive Benefits: Extended health benefits.
- Growth: Professional development support to help you stay ahead of tech trends.
- Culture: A collaborative, ego-free environment where technical expertise fuels creative magic.
