Build Affirm's AI-assisted reliability command center for production systems

This is a hands-on backend engineer role building a next-gen reliability platform at Affirm — a centralized command center plus AI agents for incident triage and root-cause exploration. Expect questions on Python API/data-system design, fast iterative 'vibe coding' with AI tools, and where LLM automation needs guardrails.
