We're pre-mainnet with real technical differentiation—not another "decentralized" project that's actually three EC2 instances in a trench coat. If you've ever been mass-migrated off a deprecated API endpoint or debugged why your subgraph stopped syncing, you understand the problem we're solving. We care more about what you can build than where you went to school.

Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.
We’re growing fast and are looking to fill the following positions:
-Chief of Staff - https://source.network/careers/chief-of-staff
-Lead Edge AI Engineer - https://source.network/careers/lead-edge-ai-engineer
