Proven track record leading model and agent hillclimbing (e.g., SFT, RL, LoRA, quantization, prompt/System Instruction tuning, synthetic data generation) and systematic AI quality and performance hillclimbing (architecting automated evaluation frameworks, autoraters, on-device latency/power benchmarks, and end-to-end loss analysis pipelines). Were looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day.
