I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us.
Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months.
Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

We’re building an AI platform for construction: offline-first mobile/web apps that automate jobsite workflows, understand documents and blueprints, and connect the field to the office.
Looking for a strong mobile engineer to own our React Native/Expo app for iOS + Android, plus parts of our TypeScript web app. Backend is Scala/Play + PostgreSQL.
You’ll build for real field conditions: no signal, gloves, sun glare, dusty tablets, large blueprints, high-res photos, and messy jobsite data.
Construction/logistics/field-industry experience is a plus.
Competitive salary, health/dental/vision, high autonomy, early team impact.
