Software Architect  🌟 

You'll architect a sophisticated, multi-tenant AI security platform —a 7-stage LLM-powered control-generation pipeline that generates right-sized cybersecurity controls with full bidirectional traceability. This is not a proof-of-concept; it's a production system where reproducibility, security, and audit-ability are foundational.

You own the high-level design decisions: where the deterministic/AI boundary lives, how to enforce multi-tenant isolation at the database layer, how to defend against prompt injection, how to validate LLM outputs at scale. You'll guide a small team of AI engineers, baseline architectural decisions early, and remain the escalation point for ambiguous calls.
