LLM Engineer Jobs
LLM Engineers ship production large-language-model features — prompt engineering, fine-tuning decisions, RAG, agent frameworks, eval harnesses, latency and cost optimisation. Overlaps heavily with AI Engineer; the LLM Engineer title signals deeper LLM-specific depth (training-side fluency, distillation, prompt-injection defence).
