Staff+ Software Engineer, Platform Portability

📋 Job Overview

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

🏢 About Anthropic

Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

🎯 The Role

Anthropic trains and serves Claude across multiple cloud providers and accelerator platforms. The Platform Portability team owns the abstractions, tooling, and deployment infrastructure that make this possible without every engineering and research team needing to become experts in different clouds.

As an engineer on Platform Portability, you'll design and build the systems that let us bring up new capacity, ship our platform to cloud provider platforms & marketplaces, and move workloads between providers with confidence. You'll work closely with our cloud partners on capabilities we need that don't exist yet, and with internal Compute, Inference, and Security teams to make "which cloud is this running on?" a question most engineers at Anthropic never have to ask. Your work directly determines how quickly and reliably we can put safe, frontier AI in front of users — wherever they are.

✅ Key Responsibilities

• Design and build the systems that let us bring up new capacity, ship our platform to cloud provider platforms & marketplaces, and move workloads between providers with confidence.
• Work closely with our cloud partners on capabilities we need that don't exist yet.
• Collaborate with internal Compute, Inference, and Security teams to make "which cloud is this running on?" a question most engineers at Anthropic never have to ask.
• Own the delivery of Claude onto third-party cloud platforms, including the build, release, and validation pipelines behind it.
• Work directly with engineering teams at our cloud partners and internal infrastructure stakeholders to land the features we need, debug platform issues, and influence their roadmaps.
• Shape how the rest of Anthropic builds for multiple clouds by reviewing designs with cloud-portability implications, mentoring engineers across the org on multi-cloud patterns, and bringing internal stakeholders into alignment through clear writing and conversation.
• Take your turn in the on-call rotation, and design the postmortems, runbooks, and incident response that help us never fail the same way twice.

📌 Required Qualifications

• Have a minimum of 8 years of practical experience building and operating production distributed systems
• Own large-scale infrastructure systems and lead ambiguous, cross-team technical projects from design through production
• Run the same production workload across multiple cloud providers, including the migration or abstraction work that made it possible
• Understand how cloud IAM models and networking primitives (VPC peering, private connectivity, service mesh) differ across providers
• Write production code in at least one general-purpose programming language (e.g., Python, Go, or Rust)
• Work confidently with Kubernetes and Infrastructure as Code (e.g., Terraform, Pulumi)
• Understand ML infrastructure and supporting interconnects
• Ship software through hyperscaler marketplaces or managed-model platforms
• Bring a background in security, compliance, or data residency for regulated or sovereign cloud environments
• Care about the societal impacts of your work and Anthropic's mission to build safe, beneficial AI
