Back End Developer

Backend Engineer (Python, Platform and Data)

Hiring on behalf of CineSports via WanXAI

CineSports is building a tool that lets football coaches upload game film, change one decision on a play, and see how likely the change is to work. We’re hiring a backend engineer to build the platform behind it.

What you’ll do

• Build user signup, login (including SSO) and role-based access for coaches and analysts, with each team’s data kept isolated.
• Design and run data storage: PostgreSQL for metadata and results, S3-compatible storage for film, and Parquet for play data.
• Build the pipelines that take uploaded film through processing jobs on GPU workers and store versioned play records, plus the APIs (FastAPI) that coaches’ tools use.
• Set up CI/CD, containers and monitoring, starting simple and adding complexity only when load requires it.

You should have

• Strong Python and experience running production APIs.
• Solid PostgreSQL and schema design, plus experience with object storage and columnar formats like Parquet.
• Experience with job queues and building retryable pipelines.
• A working grasp of authentication and multi-tenant data separation.

Nice to have

• Experience with video or media processing, GPU batch jobs, or ML pipelines.
• Experience with encryption at rest, audit logs and handling confidential customer data.

Why this role

You’ll shape the architecture from the start, work on a product with a clear user, and follow a defined roadmap from prototype through pilot to production. The computer vision and learning work sits with a separate team, so this role stays focused on the backend.

Details

• Type: Contract, fixed amount for a defined scope of work
• Location: Remote
• Compensation: [fixed fee, and payment milestones]
