Founding Platform Engineer - Video Infrastructure / Agnify

Remote-first (outside RU/BY)
Agnify — API for connecting video streams to vision models. We're looking for a data-layer architect: storage, indexing, and serving petabytes of video + AI metadata.
Key responsibilities:
Design storage/indexing architecture, semantic content search, retrieval optimization
Choose the tech stack (S3/GCS, PostgreSQL, etc.) — greenfield, no legacy
Requirements:
Experience with large-scale data systems, object storage, PostgreSQL
Ability to make architectural decisions under uncertainty and own the outcome
Nice to have:
Video/sensor data at scale, MCAP/Parquet formats
Rust/C++/Go, ML pipelines or inference optimization
We offer:
Founding team role, greenfield architecture, full autonomy
Your decisions ship directly to production
How to apply:
Send a brief note about a data system you've built: what it did, why you chose that stack, and what you'd do differently. No cover letter needed.
