Member of Technical Staff, Enterprise Foundations

The role

You will own foundational capabilities end to end, from data models and APIs to the control plane, runtime, SDK/CLI, and console. You will design primitives for large customers, including identity, authorization, billing, and data isolation.

What you will do

• Own foundational capabilities end to end and migrate live systems onto them
• Design primitives like organizations, sub-accounts, groups, roles, and service identities
• Connect systems to enterprise directories through federation and provisioning
• Design multi-tenant authorization, policy enforcement, and audit systems
• Make usage metering, spend controls, and billing correct and legible at scale
• Own data isolation and key management across AWS, GCP, and Azure
• Deploy and operate Fireworks inside a customer's own cloud
• Solve data residency and regional isolation for customers
• Use AI tooling aggressively to automate yourself

Required qualifications

• 4+ years building and operating production backend or distributed systems at scale
• Strong server-side engineering skills in Go, Python, C++, TypeScript, or similar
• Experience designing APIs and data models that other teams build on
• Hands-on depth in at least one major cloud (AWS, GCP, or Azure): IAM and workload identity, KMS, object storage, and VPC networking
• A track record of owning an ambiguous, cross-team workstream from requirement through production
• Willingness to work directly with customers

Nice to have

• Enterprise identity and tenancy: SSO, SCIM provisioning, RBAC/ABAC, audit logging, and org modeling
• Metering, quotas, or billing systems where correctness is customer-visible
• Applied cryptography and key management: envelope encryption, KMS, and threat modeling
• Kubernetes depth and infrastructure-as-code fluency (Terraform, GitOps)
• Familiarity with LLM inference and fine-tuning

Benefits

• Solve Hard Problems: Tackle challenges at the forefront of AI infrastructure
• Build What’s Next: Work with bleeding-edge technology
• Ownership & Impact: Join a fast-growing, passionate team
• Learn from the Best: Collaborate with world-class engineers and AI researchers
