AI Engineer

At Lilly, the work is demanding because patients are waiting. We unite caring with discovery to help make life better for people around the world, knowing that every decision, every detail, and every day matters. Headquartered in Indianapolis, Indiana, our over 50,000 employees around the globe take on complex challenges to discover and deliver life-changing medicines, strengthen how health is understood and managed, and support the communities we serve. This is hard, urgent, selfless work—but it’s work worth doing. If you’re driven by purpose and ready to bring your best to work that truly matters for patients, we invite you to join us.  Where AI Meets Medicine: Build the Future of Drug Discovery in the Heart of Silicon Valley! Making medicine that’s never been made means doing what’s never been done. If you’re an engineer, scientist, or builder who thrives on problems no one has solved before, this is your invitation; we want you on the team. We are ready to challenge the status quo and push medicine forward, all in the name of health.  Are you up for the challenge?  If so, join us! About the Lilly and NVIDIA Partnership Lilly and NVIDIA are launching a new AI co-innovation lab in the heart of Silicon Valley — an up-to-$1 billion, multi-year commitment to solve drug discovery’s toughest challenges. The lab brings Lilly scientists, technologists, chemists and biologists together with NVIDIA engineers under one roof. Together, we are building purpose-built foundation and frontier AI models trained on Lilly data at scale, tightening the feedback loop between automated wet labs and computational dry labs, designing the next generation of medicines for millions of patients across the globe. What You’ll Be Doing As an AI Engineer, you will turn advanced AI models into reliable tools that support drug discovery. You will build, train, evaluate, and deploy AI systems, working closely with AI Scientists to shape model design and technical decisions. This is a hands-on role with opportunities to contribute to both engineering and scientific innovation. You'll collaborate with AI Scientists, ML Ops Engineers, Data Engineers, and NVIDIA experts to develop cutting-edge AI solutions. How You’ll Succeed AI and Automation Execution: Develop and apply innovative AI techniques to solve complex business challenges, creating tailored solutions that drive strategic value and transform clinical research processes that support AI scientists. Full Stack Development: Build and implement AI-driven models and applications across the full stack, from backend services to frontend interfaces. System Architecture and Design: Design and uphold resilient system architectures to guarantee optimal performance, scalability, and security across all platforms. Handle large scale model development. Cross-Disciplinary and Organization Collaboration: Effectively engage with colleagues to gather innovative ideas and insights, fostering a collaborative environment that inspires and motivates team members to innovate and explore creative solutions in AI development. Ethics and Compliance in Development: Adhere to ethical guidelines in AI usage and data handling, ensuring compliance with all relevant regulations and maintaining the highest standards of data privacy and security. Elevate engineering excellence through architecture reviews, code quality leadership, and mentorship, while safeguarding Lilly's proprietary data, models, and intellectual property. What You Should Bring Advanced Python with production experience in PyTorch or JAX, and a track record of taking machine learning models from research code to working systems. Hands-on distributed training on multi-GPU, multi-node infrastructure (DDP, FSDP, DeepSpeed, or Megatron), with GPU performance profiling and optimization. Experience optimizing and serving models for inference (Triton, vLLM, or TensorRT-LLM) with containerization and scheduling (Docker, Kubernetes, Ray, or Slurm).
