This team sits at the intersection of ML systems, distributed infrastructure, and developer experience, creating the platform that powers autonomous AI agents at scale.You'll work on hard, forward-looking problems with few established patterns, including secure code execution, agent state management, model routing, identity and authentication, and resource management for long-running agent workflows.This role is a strong fit for someone who combines systems depth with ML intuition. You should be comfortable building reliable infrastructure, thinking through distributed systems tradeoffs, and understanding how emerging agentic capabilities shape platform design.What You'll Work On.Secure execution environments for agent-generated codeIdentity, authentication, and trust boundaries for agentsModel routing and orchestration across different model types and environmentsRate limiting, quotas, and resource management for agent workflowsState management, memory, and filesystem abstractions for agents.In This Role You WillTurn emerging ML research ideas into production-ready infrastructureBuild core platform capabilities for execution, storage, and state managementPrototype and evaluate new technologies, then help decide what should move into productionPartner with research teams to shape infrastructure based on what future agent systems will needYou May Be a Good Fit If You HaveExperience building production ML infrastructure with strong systems fundamentalsHands-on work with agentic systems, multi-agent workflows, or agent development frameworksFamiliarity with model routing and LLM provider frameworks across different model types and environmentsExperience with scalable, fault-tolerant distributed systems and KubernetesA track record of moving quickly on prototypes and making good decisions about productionization.BonusExperience across on-prem, private cloud, and public cloud environmentsFamiliarity with storage systems, embedded databases, or filesystem abstractionsExperience with code execution sandboxes such as gVisor, Firecracker, Kata, or WASM runtimesInterest in emerging ML infrastructure, edge inference, or browser-native modelsOpen-source contributions to LLM or agent infrastructure projectsExperience with identity, workload auth, or capability-based security systems.If some of the above doesn't line up perfectly with your experience, we still encourage you to apply!We value and celebrate diversity and strive to create an inclusive work environment for all.
