Job summary

Anthropic is seeking an engineer for the Platform Portability team to design and build provider-agnostic cloud abstractions and tooling. You will own end-to-end delivery across cloud platforms, collaborating with external partners and internal teams to enable portable, scalable AI infrastructure.

You will mentor engineers on multi-cloud patterns, participate in on-call rotations, and drive portability across clouds while ensuring safe, reliable frontier AI deployment.

Qualifications

• 8+ years of practical experience building and operating production distributed systems.
• Experience with multi-cloud platforms and cloud-provider integrations.
• Proficiency in at least one general-purpose language (Python/Go/Rust).

Responsibilities

• Design and build provider-agnostic abstractions for cloud platforms and their storage, messaging, and connectivity.
• Own end-to-end delivery of build, release, and validation pipelines behind cloud integrations.
• Collaborate with cloud partners and internal Compute, Inference, and Security teams to enable multi-cloud deployments.
• Lead cross-team technical projects from design through production and review architectures for portability implications.
• Mentor engineers across the org on multi-cloud patterns and incident response.
• Participate in on-call rotations and design postmortems, runbooks, and incident response processes.

Job description

• 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
• Portable infrastructure. We build the provider-agnostic abstractions for storage, messaging, and connectivity that let Anthropic’s systems run on any cloud, and they have to hold up at the scale of frontier model inference. You’ll design and build those abstractions, plus the tooling that lets internal teams provision, configure, and operate services across clouds through one consistent interface
• You’ll also hunt down the provider-specific assumptions hiding in our codebase and set the patterns that keep new ones from creeping in
• Claude on partner clouds. We ship Claude onto third-party cloud platforms, and every launch has to be repeatable
• You’ll own that delivery end to end, including the build, release, and validation pipelines behind it. You’ll 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. Expect to go deep on native integrations with each provider, and to do the cross-cutting work that keeps our platform consistent across all of them
• Across both, you’ll shape how the rest of Anthropic builds for multiple clouds. You’ll review designs with cloud-portability implications, mentor engineers across the org on multi-cloud patterns, and bring internal stakeholders into alignment through clear writing and conversation. You’ll also take your turn in the on-call rotation, and you’ll design the postmortems, runbooks, and incident response that help us never fail the same way twice
• 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

Benefits

• Comprehensive health, dental, and vision insurance for you and your dependents
• Inclusive fertility benefits via Carrot Fertility
• 22 weeks of paid parental leave
• Flexible paid time off and absence policies
• Mental health support for you and your dependents
• Competitive salary and equity packages
• Optional equity donation matching at a 1:1 ratio, up to 25% of your equity grant
• Retirement plans with competitive matching
• Life and income protection plans
• $500/month flexible wellness and time saver stipend
• Commuter benefits
• Annual education stipend
• Home office stipends
• Relocation support for those moving for Anthropic
• Daily meals and snacks in the office
