You'll work at the intersection of large language models and domain-specific engineering challenges, creating AI experiences that dramatically accelerate how engineers work.
Responsibilities
- Develop Agentic AI systems: Design and implement tools for agents to call; build reasoning, planning, and orchestration capabilities that enable the copilot to autonomously execute complex engineering workflows
- Design and optimize RAG pipelines: Build retrieval-augmented generation systems over engineering documentation, physics simulation results, and domain knowledge bases
- Implement memory and context management: Create persistent conversation memory and context systems that maintain coherent, long-running engineering sessions
- Fine-tune and adapt LLMs: Customize foundation models for Physics AI and physics simulation domain expertise through fine-tuning, prompt engineering, and evaluation frameworks
- Deploy and scale LLM infrastructure: Build robust, production-grade systems for self-hosting and serving LLMs, optimizing for latency, cost, and reliability
- Integrate with Physics AI and physics simulation platform: Connect LLM capabilities with Luminary's Physics AI training/evaluation/inference pipelines, physics simulation solvers, mesh tools, and analytics APIs to enable end-to-end automation
- Establish evaluation frameworks: Define metrics and build testing infrastructure to measure copilot quality, accuracy, and user satisfaction
- Collaborate cross-functionally: Work closely with Physics AI researchers, platform engineers, and product teams to deliver customer-centric AI experiences
Qualifications
Required
- Bachelor's degree or higher in Computer Science, Mechanical Engineering, Aerospace Engineering, or related field
- 5+ years of experience building production software or ML systems
- 2+ years of hands-on experience developing LLM-powered applications
- Strong proficiency in Python
- Proficiency using coding agents such as Claude Code
- Experience with Agent Evals
- Deep understanding of LLM architectures, prompting techniques, and their capabilities/limitations
- Experience designing tools/functions for agents to call, with planning and reasoning
- Experience with multi-agent orchestration and coordination
- Hands-on experience with RAG systems and memory/context management, including vector databases, embedding models, chunking strategies, and long-running session handling
- Experience building MCP (Model Context Protocol) servers to expose tools and capabilities to external agents
- Experience with agent frameworks (e.g., LangChain, LlamaIndex, Google ADK, Autogen, Claude Agent SDK, or custom solutions)
- Familiarity with Physics AI, CAE, or physics simulation domains a plus
- Experience fine-tuning LLMs for domain-specific applications
- Hands-on experience self-hosting and serving LLMs in production environments
Nice to Have
- Experience with TypeScript for full-stack development
- Experience with Go for backend systems
- Familiarity with Kubernetes for container orchestration and deployment
