About Modular At Modular, we’re on a mission to revolutionize AI infrastructure by systematically rebuilding the AI software stack from the ground up. Our team, made up of industry leaders and experts, is building cutting-edge, modular infrastructure that simplifies AI development and deployment. By rethinking the complexities of AI systems, we’re empowering everyone to unlock AI’s full potential and tackle some of the world’s most pressing challenges.

If you’re passionate about shaping the future of AI and creating tools that make a real difference in people’s lives, we want you on our team. You can read about our culture and careers to understand how we work and what we value.

What You Will Work On As an intern on the MAX Serve team, you'll tackle real performance problems in state-of-the-art GenAI models like DeepSeek, Llama, and Qwen. You'll execute on a critical project related to performance optimization across the Python/Mojo boundary, working from GPU kernels up through compiler, framework, and multiprocessing optimizations. Your work will involve profiling bottlenecks in multi-billion parameter models, implementing bleeding-edge research (FP8 quantization, speculative decoding, advanced attention), and shipping optimizations to our open-source MAX platform that developers worldwide depend on.

LOCATION: Candidates based in the United States are welcome to apply. To support growth and collaboration, all interns will work in a hybrid capacity at our Los Altos, CA office (minimum 2 days per week on-site) with relocation assistance provided for out-of-state candidates.

What You Will Learn Hands-on experience optimizing GenAI workloads at the intersection of compilers, runtimes, and distributed systems. You'll gain deep expertise in performance optimization techniques, profiling tools, and systems programming while working with Mojo: our next-generation programming language. Mentorship from experienced engineers on the MAX Serve team who work on problems spanning GPU kernels to serving APIs. You'll present and demo your contributions to the engineering organization and make lasting contributions to open-source technology that powers production deployments achieving 200+ tokens/second on multi-GPU systems.
