About the role
The AI Platform team owns Affirm's paved path for building, running, evaluating, and governing AI systems. Our customers are not only Affirm users, but also every engineer and a growing set of production workloads at Affirm.

Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Plan, execute, and own technical decisions and projects within the AI Platform team, from design through launch and on-call
- Design and build the gateway, runtime, and evaluation services that take AI workloads at Affirm from pilot to production, securely scaling across millions of users and their transactions
- Make AI spend attributable and governable: build the identity, quota, routing, caching, and failover controls that let teams adopt new models and tools without re-solving the same platform problems
- Partner with security, infrastructure, and product engineering teams to set the guardrails for agentic workloads and the on-behalf-of identity model for tool access
- Create and monitor metrics for your team's systems, and own the operational health of what you ship: monitoring, alerting, runbooks, and on-call
- Set and improve code review and design standards, and advocate for them beyond your team through writing and tech talks
