Software Engineer, Infrastructure

ABOUT RUNLOOP Runloop.ai http://runloop.ai is pioneering the next generation of infrastructure and orchestration to power the Agentic Web/age of AI Agents. Our platform empowers developers to deploy agents that write code, browse the web, and use computers the way a human would. We're a small team of former Google and Stripe engineers, including the co-founder of Google Wallet and 100% of its founding team, dedicated to solving the complex challenges of productionizing AI for software engineering at scale. THE ROLE We 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 our 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 with MicroVMs, Kubernetes, AWS, and GCP to create a robust, scalable, and secure foundation for our users' AI software engineering agents. RESPONSIBILITIES - Drive performance optimization across the platform, including deep dives into networking, kernel-level behavior, and database/backend internals. Faster is always better, and this will be a constant focus area - Design, build, and own distributed systems from the ground up, not just operate infrastructure other teams have already built, spanning sandboxed execution environments, containerization, MicroVMs, and distributed job orchestration - Build and scale secure VPC deployments for enterprise customers in highly regulated industries, including defense - Own reliability, security, and observability of the systems you build, from design through monitoring and incident response - Diagnose and resolve complex networking, kernel-level, and low-level performance issues across the stack - Work with Kubernetes, Docker, Terraform, Pulumi, Grafana, and Prometheus to build infrastructure that scales with rapidly growing demand - Collaborate with product engineering teams to integrate infrastructure with Runloop's AI software engineering platform - Optimize infrastructure for performance, scalability, and cost-efficiency - Stay up-to-date with the latest advancements in cloud infrastructure and AI technologies QUALIFICATIONS - Strong computer science fundamentals, backed by a degree from a top-tier CS/EE program, or equivalent experience - 4-7 years of experience in software engineering, with a focus on infrastructure and platform development - Strong experience with MicroVMs, Kubernetes, AWS, and GCP - Experience building and scaling secure VPC deployments, ideally for enterprise customers in regulated or defense environments - Proficiency with Docker, including Docker-in-Docker container builds - Experience with infrastructure as code (IaC) tools, such as Terraform or Pulumi - Experience with observability and monitoring tooling, such as Grafana and Prometheus - Proficiency in one or more systems programming languages, such as Golang, Rust, or Java - Familiarity with DevOps practices and tools, such as CI/CD pipelines and configuration management - Excellent problem-solving skills and a passion for building scalable, reliable systems BONUS POINTS - Experience with AI/ML workloads and infrastructure - Experience in container optimization with projects like overlaybd, buildkit, or discoball - Experience with security best practices and compliance requirements for cloud infrastructure in regulated industries - Contributions to open-source projects BENEFITS - Competitive salary and equity - Comprehensive health, dental, and vision insurance for employee and dependents - Opportunity to work on cutting-edge technology and make a real impact on the future of software engineering - Daily catered lunch for all employees and a fridge full of your favorite snacks and drinks LOCATION: - Onsite 4 days a week in San Francisco; Optional 1 day a week remote Join Us! If you're excited about shaping the future of AI-driven software engineering and empowering developers to build the next generation of AI powered coding tools, we want to hear from you.
