Role Description The Community You Will Join: - Dev Tools’ mission is to help Airbnb engineers and AI agents build, validate, review, and ship high-quality software quickly, reliably, and safely. - AI-assisted development is rapidly increasing the speed, volume, and concurrency of software delivery. - Our team is building the infrastructure needed to support that growth - from cloud development environments and agent execution platforms to source control, code review, validation, and polyglot monorepo tooling. The Difference You Will Make: - As a Software Engineer on Dev Tools, you will design, build, and operate foundational systems used across Airbnb engineering. - You will work on technically challenging infrastructure problems involving distributed systems, Kubernetes, developer workflows, scalability, reliability, and cost efficiency. - Partner closely with teams across Developer Platform, DevAI, CI/CD, Cloud Infrastructure, and Security. - You won't just build - you'll shape the technical direction and set the bar for craft on a small, high-impact team. High leverage: - Every improvement you make is felt by every engineer at Airbnb — plus the AI agents running on behalf of those engineers. Greenfield platform work: - The async agent execution platform is nascent. You'll be making foundational decisions about how it scales, not inheriting someone else's choices. Clear business stakes: - Our cloud workspace costs nearly doubled in Q1 as agentic usage surged. - The tradeoff between developer productivity and infrastructure spend is real, visible, and yours to influence. Small team, big scope: - This is not a large-org role where your contribution gets diffused. - The team is intentionally lean - your work ships and your decisions matter. A Typical Day: - Build and operate cloud development environments and execution platforms for engineers and AI agents. - Scale Kubernetes-based worker pools, control planes, and APIs for parallel and asynchronous workloads. - Improve AirDev validation so engineers and agents can test changes quickly before CI. - Strengthen source-control and code-review systems as PR volume, automation, and concurrency grow. - Improve developer workflows across build, test, dependency management, and polyglot monorepo tooling. - Diagnose production issues across distributed systems, networking, storage, and orchestration. - Setting technical direction and making high-stakes architectural decisions with significant ambiguity. - Mentoring engineers on the team and raising the quality bar through code review and design feedback. Qualifications - 2-4+ years of industry experience with bachelor’s and/or Master’s degree, preferably in CS, or equivalent experience. - Experience leading and shipping large scope technical projects in collaboration with multiple experienced engineers. - You are a full-cycle developer: strong ownership and experience building and operating high-scale, distributed systems across the full software life cycle. - Familiarity with container and orchestration technologies such as Docker and Kubernetes. - Excellent communication skills - you can explain complex infrastructure tradeoffs to engineers at all levels and drive cross-team alignment without formal authority. - Strong problem solver with solid debugging skills. - Passionate about developer productivity and making developer lives better. - Cloud infrastructure and Kubernetes: You've built systems that run reliably at scale on AWS. - Platform thinking: You've built infrastructure that other teams build products on top of. - Cost and efficiency: You treat infrastructure spending as a first-class concern. - Agent or async workloads (a plus): You've thought about the operational characteristics of async, autonomous, or long-running compute workloads. - Developer tooling (a plus): You care about the end-to-end developer experience. - Go, Python, or similar server-side languages. Requirements - Experience in one or more of the following areas is especially valuable: - Developer environments, remote development platforms, or sandboxed workload execution. - Infrastructure for AI agents or asynchronous compute workloads. - CI/CD, integration testing, build systems, or pre-submit validation. - Git, GitHub Enterprise, source-control infrastructure, or large-scale repository hosting. - Code-review systems, policy enforcement, code ownership, or automated review tooling. - Kubernetes operators, workload scheduling, autoscaling, resource isolation, or capacity management. - Bazel, monorepo tooling, dependency management, or polyglot build infrastructure. - Platform APIs, control planes, worker pools, caching systems, or distributed queues. - Authentication, authorization, secrets management, or secure workload execution. - Infrastructure cost optimization and capacity planning. Location This position is US - Remote Eligible. The role may include occasional work at an Airbnb office or attendance at offsites, as agreed to with your manager.
