Renaissance Philanthropy·Remote (worldwide) Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments. RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years. We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student. We're looking for folks who: - have built and operated production ASR or speech-processing systems - know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment - can speak the languages of both research and engineering - want to help create a world where all children learn to read well.

Cardog·Full-time https://cardog.app/careers We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry. Some of what's interesting: - A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work. - Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles. - We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car. Hiring: VIN Decode Engineer, Data Platform Engineer, Infrastructure Engineer, Founding Engineer (dealer platform). TypeScript, Postgres, Cloudflare Workers.

Source ( )·Full-Time Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape. An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest. We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb . We think it's the best memory an agent can have, bar none. We’re growing fast and are looking to fill the following positions: -Chief of Staff - https://source.network/careers/chief-of-staff -Growth Hacker, Developer Adoption - https://source.network/careers/growth-hacker-developer-adopt... -Head of Business Development - https://source.network/careers/head-of-business-development
