Runloop provides an enterprise infrastructure platform for developing, evaluating, and deploying AI coding agents, offering secure isolated devbox sandboxes, GitHub-integrated developer tooling, snapshots, blueprints, and public benchmarks.
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 As a Full Stack Software Engineer at Runloop, you'll be at the forefront of building a revolutionary platform that enables the next generation of AI-augmented software engineering tools. You'll be a hands-on contributor working directly with our team. You'll work across the stack, from our core containerization and microVM infrastructure to the developer-facing APIs, SDKs, and UI built on top of it. Along the way, you'll tackle critical projects around billing, usage tracking, and marketplace integrations, plus the unique challenges of AI agent orchestration and code execution. RESPONSIBILITIES - Lead the evolution of our usage tracking and billing systems, integrating new Stripe V2 APIs to support Runloop's growing platform - Drive our expansion into major cloud marketplaces like Google Cloud and Azure - Design and implement key components of our AI software engineering platform - Design and ship user-facing workflows and APIs, and create intuitive SDKs and developer tools that make it easy for our users to build and scale their AI coding solutions on top of Runloop across the stack, including UI - Work across the stack on our core platform — leveraging Docker, containerization, and microVMs — to build highly scalable and efficient systems capable of handling the unique demands of AI-powered software engineering tools, including long-running AI jobs and extreme parallelization - Implement robust security measures to ensure the safe execution of AI agents and protect sensitive codebases - Work closely with product, design, and infrastructure partners to translate user needs into high-quality technical solutions. Participate in technical design discussions and contribute to roadmap planning - Write maintainable, well-tested code. Improve code quality, developer workflows, and internal tooling to help the team move quickly and confidently QUALIFICATIONS - Strong computer science fundamentals, backed by a degree from a top-tier CS/EE program, or equivalent experience - 4-7 years of experience building performant products or infrastructure deployed at scale, with a strong background in full stack software engineering - Hands-on builder who can reason through complex systems and thrives in a high-ownership environment - Experience building developer platforms or APIs - Proficiency in languages commonly used in AI and full stack development (e.g., Python, Java, TypeScript) - Experience with cloud infrastructure, containerization (Docker), and orchestration technologies; familiarity with microVMs a plus - Experience with billing, usage-metering, or payments systems is a strong plus - Strong problem-solving skills and ability to tackle novel technical challenges - Passion for developer tools and improving software engineering processes BONUS POINTS - Familiarity with AI/ML concepts, particularly in the context of code generation or analysis - Experience integrating with cloud marketplaces (Google Cloud, Azure, AWS) 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!
