About the Role

As a Member of Technical Staff, Inference, you will build and optimize systems that bring frontier biological AI models into production. Your work will focus on delivering state-of-the-art inference performance for large-scale genome and multimodal biological models across a wide range of real-world applications, including therapeutics, diagnostics, synthetic biology, and biodefense. This is a highly technical role at the intersection of AI systems, distributed computing, and model deployment, requiring deep expertise in large language model inference, kernel optimization, GPU systems, and performance engineering.

Responsibilities

  • Drive end-to-end performance improvements by identifying and eliminating bottlenecks across the inference stack.
  • Develop high-performance inference primitives, including GPU kernels, numerical operators, and serving infrastructure.
  • Partner with external customers and collaborators to deploy models in production environments and solve challenging technical problems.
  • Build scalable deployment infrastructure for serving, monitoring, benchmarking, and operating foundation models.
  • Collaborate with research and platform teams to ensure efficient deployment of new model architectures and translate AI research into real-world impact.

Requirements

  • Expertise in large-scale AI inference systems with proven experience optimizing, deploying, and operating LLMs or other foundation models in production.
  • Strong performance engineering and kernel development skills, with a deep understanding of GPU architectures and experience with CUDA, Triton, or equivalent technologies.
  • Systems-level thinking with the ability to diagnose and solve bottlenecks across the full stack.
  • Strong software engineering fundamentals with proficiency in Python and modern ML frameworks such as PyTorch.
  • Customer and deployment orientation with experience delivering production AI systems that solve real-world problems.
  • Excellent technical communication skills for effective collaboration across diverse teams.

About the Company

  • Radical Numerics is an AI research lab building general biological intelligence with the mission to master the code of life and reduce human suffering.
  • The team created Evo, starting the field of generative genomics, with work featured in Science and presented at TED2025.
  • Evo was used to create the first AI gene therapy tool CRISPR-Cas9 and the first AI whole genome from scratch.
  • Evo 2, featured in Nature, is the largest fully open source AI project across any domain.
  • Radical Numerics applies distributed systems, model architecture, and numerics research to biology, redesigning the foundation model training stack to turn scientific data into intelligible, generative models.
  • The company was founded to develop both the power to design and the responsibility to defend against AI-generated bioweapons, recognizing the inseparable nature of these forces.
