You will own the inference backbone behind QVAC's local AI stack: the C++ systems layer that makes models run fast, reliably, and predictably on real user hardware. The role is centered on engineering quality at runtime level, including startup behavior, memory pressure, throughput/latency balance, and long-session stability. You will define and evolve the core abstractions that inference features depend on, so new capabilities can be added without sacrificing performance or maintainability.

You'll ensure that the inference layer is stable, optimized, and ready for integration with the rest of the stack.
This role is for engineers who want to work close to the metal, enabling private and fast on-device AI without relying on cloud infrastructure.
Responsibilities
- Work on deploying machine learning models to edge devices using the frameworks: llama.cpp, ggml
- 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
Requirements
- Strong programming skills in C++
- Strong experience with Llama.cpp and ggml inference engines, which facilitates the deployment of models to specific GPU architectures
- Experience with any GPU framework between Cuda, Vulkan, Metal, OpenCL
- Good understanding of deep learning concepts and model architectures
- Experience with transformers, LLMs, 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
Bonus points if
- You know how to train/fine-tune a LLM
- You have productionized models
- You have research experience in new model architectures
- You have experience with distributed systems
- Javascript experience
