Job Description
The Future of AI is Here. Nexus Horizon Labs is pioneering the technology stack for 2026. We are seeking a visionary Senior AI Architect to lead the development of next-generation Agentic AI and autonomous intelligent systems.
In this role, you won't just be maintaining models; you will be architecting the brain of the future. You will define how autonomous agents interact, reason, and execute complex tasks in dynamic environments. If you are passionate about the intersection of Large Language Models (LLMs), multi-agent systems, and the future of human-computer interaction, we want to hear from you.
Why join us?
- Work on the foundational technologies that will define the AI landscape of 2026 and beyond.
- Competitive compensation package with equity for early contributors.
- Flexible remote-first culture with a hub in San Francisco.
Responsibilities
- Design and implement scalable Agentic AI architectures capable of autonomous decision-making and tool usage.
- Develop and fine-tune multi-modal Large Language Models (LLMs) for specific high-impact domains.
- Build robust evaluation frameworks to measure agent performance, safety, and alignment.
- Collaborate with product teams to integrate autonomous agents into seamless user experiences.
- Research cutting-edge advancements in AI reasoning, memory, and planning mechanisms.
- Optimize inference pipelines for latency and cost-efficiency in production environments.
Qualifications
- Master’s or PhD in Computer Science, Artificial Intelligence, or a related field (4+ years of industry experience may substitute).
- Deep expertise in Python, PyTorch, and TensorFlow.
- Proven experience building and deploying LLM-based applications or Agentic workflows.
- Strong understanding of prompt engineering, RAG (Retrieval-Augmented Generation), and model fine-tuning.
- Experience with vector databases (Pinecone, Milvus, Weaviate) and vector search.
- Excellent problem-solving skills and ability to thrive in a fast-paced, research-driven environment.
