Tether Operations Limited is hiring an AI Inference Engineer for QVAC. You will own the inference backbone behind our local AI stack: the C++ systems layer that makes models run fast, reliably, and predictably on real user hardware. Your work directly enables private, on-device AI experiences and helps set the technical foundation for QVAC's next generation of peer-to-peer AI products.
What You'll Do
- Deploy machine learning models to edge devices using frameworks like llama.cpp, ggml, and ONNX.
- Collaborate closely with researchers to assist in coding, training, and transitioning models from research to production environments.
- Integrate AI features into existing products, enriching them with the latest advancements in machine learning.
- Define and evolve the core abstractions that inference features depend on, so new capabilities can be added without sacrificing performance or maintainability.
- Work on the C++ layer that powers local AI, porting and enhancing inference engines to run efficiently on edge devices.
- Focus on the runtime: making models load faster, run leaner, and perform well across different hardware.
- Ensure the inference layer is stable, optimized, and ready for integration with the rest of the stack.
What We're Looking For
- Excellent programming skills in C++.
- Strong experience with Llama.cpp and ggml inference engines.
- Good understanding of deep learning concepts and model architectures.
- Experience with transformers, LLMs, and Diffusion models.
- Demonstrated ability to rapidly assimilate new technologies and techniques.
- A degree in Computer Science, AI, Machine Learning, or a related field, complemented by a solid track record in AI R&D.
- Excellent English communication skills.
Nice to Have
