Tether, best known as the company behind the world’s largest stablecoin, is now actively recruiting inference engineers to work on something that has nothing to do with dollar pegs. The company is building out its AI division through QVAC, a local-first platform designed to run artificial intelligence directly on user devices, no cloud required.
The job listings call for remote AI Inference Engineers and AI Research Engineers with deep experience in C++ and specialized tools like llama.cpp and ggml. If those names don’t ring a bell, here’s the translation: these are the open-source inference engines that let large language models run on laptops, phones, and other edge hardware instead of massive data centers.
What QVAC actually is
QVAC was first announced in May 2025 as Tether’s bet on a future where AI doesn’t require users to hand their data to cloud providers. Think of it as the opposite of the ChatGPT model, where every query travels to a remote server. QVAC keeps computation local, meaning the AI runs on your device and your data stays with you.
The platform has already shipped several products. Workbench functions as a local AI assistant, while Fabric serves as a high-throughput inference runtime. In December 2025, the company introduced QVAC Health, pushing into privacy-sensitive territory where on-device processing isn’t just a nice-to-have but a genuine necessity.
Developer incentives and the SDK rollout
Tether launched the QVAC SDK in April 2026, giving outside developers the tools to build applications on top of the platform. Shortly after, the company announced a developer grants program offering between $1,500 and $4,000 per task. The grants are paid in USDT or BTC.
Why a stablecoin company is building AI infrastructure
The privacy angle is what makes QVAC distinct from the dozens of other crypto-adjacent AI projects that have surfaced over the past two years. Most blockchain-AI ventures focus on decentralized compute marketplaces or tokenized model access. QVAC is doing something different: it’s betting that the future of AI is local, not distributed across nodes or centralized in a handful of corporate data centers.
QVAC creates new utility for USDT and BTC beyond trading and transfers. If the developer grants program scales and QVAC attracts a meaningful number of builders, it establishes a demand channel for Tether’s core product that exists entirely outside of exchange trading volume.
