Software Engineer, Platform

About the role

We are looking for software engineers to join our Platform organisation. We build the foundational primitives that accelerate product development across Anthropic, and own infrastructure and systems that teams depend on to ship reliably and at scale.

Responsibilities

• Architect and optimise the critical development infrastructure that powers our AI product development, including dev environments, observability, and CI/CD pipelines.
• Partner closely with product teams to understand their development workflow and eliminate friction points.
• Work on problems where reliability and enterprise trust are the bar: token refresh at scale, admin controls that let IT govern what agents can do, proxy infrastructure that stays up when partner servers don't.

Platforms

• Platform Acceleration: We work on maximising the developer productivity of product engineers at Anthropic.
• Service Infra: We build and maintain the core infrastructure that powers Anthropic's engineering organisation, from service mesh and observability systems to deployment pipelines and shared libraries.
• Multicloud: We build and maintain the infrastructure that enables Anthropic to operate across multiple cloud providers.
• Auth & Identity: We build and maintain the critical infrastructure that powers identity and authentication across Anthropic's product suite.
• Connectivity: Our mission is to make Claude the most connected AI.
• API Distributability: The Claude API today is a rapidly growing platform serving developers and enterprises at scale.
• Platform Intelligence: We build the training systems that adapt Claude to specific customer workloads.

Requirements

• Have a minimum of 5 years of practical experience building backend product or platform systems,distributed systems, cloud-native products, developer tools, or external developer facing products.
• Have strong fundamentals in service-oriented architectures, networking, and systems design.
• Are proficient in Python, Go, Rust, or similar systems languages.
• Have experience with cloud infrastructure (GCP, AWS, or Azure), container orchestration (Kubernetes), and/or multi-cloud networking.

Benefits

• Annual compensation range: $320,000-\$320,000 USD.
• Visa sponsorship available.
• Flexible work arrangements, including remote work options.
