Software Engineer, Infrastructure

Infrastructure SWE Role at RunloopRunloop.ai is building the foundational infrastructure for the next generation of AI development. We provide AI engineers and data scientists with lightning-fast, secure, and reproducible code sandboxes for agents. Our platform enables teams to experiment, iterate, and deploy their agents without the friction of environment setup and dependencies. We are a small but mighty team dedicated to building a rock-solid platform that empowers innovation in the age of AI.The RoleWe are looking for an infrastructure SWE to own the core systems that make AI agent workloads fast, safe, and reliable at Runloop. You'll be a hands-on contributor working directly with a world-class team — including the co-founder of Google Wallet and 100% of its founding team — on a brand new compute paradigm that powers the next generation of AI agents. This is foundational infrastructure work close to the metal: building execution environments, orchestration, isolation, and networking for enterprise customers in highly regulated spaces. You'll work on cutting-edge technologies like MicroVMs, Kubernetes, AWS, and GCP to create a robust, scalable, and secure foundation for our users' AI software engineering agents.ResponsibilitiesPerformance Optimization: Drive performance optimization across the platform — faster is always better, and this will be a constant focus areaSecure Enterprise Deployments: Build and scale secure VPC deployments for enterprise customers in highly regulated industries, including defenseCore Infrastructure: Design and operate core infrastructure for sandboxed execution environments, containerization, MicroVMs, and distributed job orchestrationReliability & Observability: Own reliability, security, and observability of the systems you build — from design through monitoring and incident responsePlatform Tooling: Work with Kubernetes, Docker, Terraform, Pulumi, Grafana, and Prometheus to build infrastructure that scales with rapidly growing demandCross-Functional Collaboration: Collaborate with product engineering teams to integrate infrastructure with Runloop's AI software engineering platformScalability & Cost-Efficiency: Optimize infrastructure for performance, scalability, and cost-efficiencyContinuous Learning: Stay up-to-date with the latest advancements in cloud infrastructure and AI technologiesQualificationsBachelor's degree in Computer Science or a related field, or equivalent experience.4-7 years of experience in software engineering, with a focus on infrastructure and platform developmentStrong experience with MicroVMs, Kubernetes, AWS, and GCPExperience building and scaling secure VPC deployments, ideally for enterprise customers in regulated or defense environmentsProficiency with Docker, including Docker-in-Docker container buildsExperience with infrastructure as code (IaC) tools, such as Terraform or PulumiExperience with observability and monitoring tooling, such as Grafana and PrometheusProficiency in one or more systems programming languages, such as Golang, Rust, or JavaFamiliarity with DevOps practices and tools, such as CI/CD pipelines and configuration managementExcellent problem-solving skills and a passion for building scalable, reliable systemsBonus PointsExperience with AI/ML workloads and infrastructureExperience in container optimization with projects like overlaybd, buildkit, or discoballExperience with security best practices and compliance requirements for cloud infrastructure in regulated or defense industriesContributions to open-source projectsBenefitsCompetitive salary and equityComprehensive health, dental, and vision insurance for employee and dependentsOpportunity to work on cutting-edge technology and make a real impact on the future of software engineeringDaily catered lunch for all employees and a fridge full of your favorite snacks and drinksLocation:Onsite 4 days a week in San Francisco; Optional 1 day a week remoteJoin Us!
