AI Inference Tools Engineer

About Modular At Modular, a Qualcomm company , 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. About the role: At Modular we are building a next generation AI platform to power modern applications and facilitate access to cutting-edge hardware. The MAX framework is our developer-facing layer: it defines the APIs developers use to express models, integrate custom kernels, orchestrate execution, iterate on quality and ship systems into production. As an engineer on the MAX Tools team you will build the developer tooling for Modular's AI inference stack to make the engineers who build and deploy AI models more productive. You will be working on tools to help people create, debug, and optimize models and kernels. Modular’s vertically integrated ML serving stack allows you to solve a uniquely diverse set of problems, and gives you especially broad scope for creating solutions. A growing part of our work is agent-native tooling: tools designed so that AI agents can profile, triage, and debug issues under engineer guidance. LOCATION: Candidates based UK are welcome to apply. To support growth and collaboration, those in earlier career stages work in a hybrid capacity at our Edinburgh, UK office (minimum 3 days per week on-site). Senior members have both in office or remote flexibility. Onboarding for new hires is conducted in person at an appropriate office. What you will do: Enhance the MAX developer experience by creating tools that can be part of traditional and agentic workflows, by surfacing data through the entire AI stack, and by supporting a widening list of heterogeneous hardware platforms. Design, build, and maintain key technologies that support the MAX framework, such as profiling and tracing tools, debuggers and associated tools to check correctness, and metrics and dashboards to monitor the performance and health of MAX deployments. Create agent-native tooling: tools that can be used by humans and agents alike, and the agentic workflows that go around them. Write agents to bring up models, to triage issues with running systems, and to profile and optimize based on real workloads. Connect MAX tools through the entire stack: by strengthening the tooling interfaces between MAX, Mojo, and the driver APIs they run on; and by integrating tool use cleanly with the orchestration layers above.
