Xora Innovation is an early-stage startup focused on developing applied intelligence for real-world applications. The Senior AI Engineer will own the LLM systems behind the platform, working hands-on with model internals and ensuring reliable product delivery. Responsibilities - Build and ship LLM-powered capabilities end to end: prototype, evaluate, deploy, and iterate them into production services users rely on - Design agents that plan and carry out multi-step work: tool calling, structured outputs, durable state, and the judgment to know when an agent is the wrong tool - Build retrieval that gives models the right context: ingestion, chunking, embeddings, hybrid search, reranking - Fine-tune open-weight models with LoRA, QLoRA, or full-parameter tuning on multi-GPU, curating the training data and choosing the method by task, compute budget, and target - Build evaluation loops that gate what ships: automated scoring, LLM-as-judge, and regression tracking against curated test sets - Instrument model calls and tool use with tracing, so quality, cost, and failures stay debuggable in production - Turn LLM capabilities into clean APIs and reusable tooling that other engineers build on Skills - Bachelor's or Master's degree in Computer Science or a related engineering field, and 5+ years building and shipping production software, including deep hands-on work building LLM-powered systems in production - Strong Python and a track record of shipping reliable services: async, HTTP and streaming APIs, testing, code review - Production experience with LLMs: prompting and context engineering, tool calling, structured output, and the latency and cost work that keeps them usable - Hands-on experience designing and shipping agents: the loop, the tools, context, memory
