Source description
About the role
Act as the architecture authority – own the deterministic/AI boundary design, multi-tenant data isolation model, and LLM security posture; baseline architectural decisions in week 1 that lock the team's constraints
Technical owner from design to delivery – tailor solutions to Alpine's stated requirements (FastAPI + PostgreSQL + AWS Bedrock + ECS Fargate) while defending against scope creep and technical debt
Partner with stakeholders to capture requirements – work with client leadership to translate business and compliance needs into architectural constraints (e.g., multi-tenant isolation, run-to-run consistency guarantees, audit trails)
Assess and plan for technology insertion – evaluate architectural trade-offs (e.g., why a single bounded AI step beats two, why RLS + FORCE ROW LEVEL SECURITY beats application-layer filtering, why Pydantic schema validation is the output gate)
Manage risk identification and mitigation – surface and mitigate delivery risks (e.g., CISO golden-set availability, prompt-injection surface area, cross-tenant isolation defects) with concrete mitigation strategies
Influence and communicate vision – define the long-term product roadmap (Tools 1–5), technical vision (the 5-section Source of Truth structure, the 7-stage pipeline design), and development strategy (agentic-orchestration approach, vertical slices, always-functional milestones)
Contribute to code reviews and architectural artifacts – review critical paths (Bedrock adapter, RLS policies, Stage 4 calibration logic); document architectural decision records (ADRs) that capture the why, not just the what
Lead and mentor the team – guide the AI/LLM Lead and Backend engineers on AI reliability, security patterns, and multi-tenant design; escalate ambiguity upward rather than letting it flow down to individual engineers
