Principal Forward Deployed Engineer

Accountable for: moving the whole platform forward in code — the cross-cutting integration that makes ingest → extract → serve → orchestrate actually run together, end to end and verified. Deployed forward onto Dossier itself, not onto clients.

Responsibilities

• Hold the global, verified overview of the entire platform — all four layers and every package (@dossier/okf, extraction, ingestion, mcp, runtime, design) — and name the highest-leverage next move.
• Build the connective tissue no single layer-owner is responsible for: integration, wiring, glue, fixtures, and the last mile that makes the pieces real.
• Exercise the whole loop end to end and report the empirical state of the build — reproduce ground truth rather than trust a green claim; flag debt loud, never fabricate status.
• Route what the build learns — a seam fix to the layer owner, a direction change to the log-auditor, a scope question to the product-owner, a topology question to the principal-architect.

Decision rights

• Owns how it actually gets built and verified across layers — the breadth between layers; does not redefine the roadmap, decide topology, or reimplement a layer-owner's depth.
• "Done" only after it is reproduced and runs; reports reality, not claims.

Boundary: vs. Principal Platform Architect (decides topology, doesn't code) and Product Owner (what / why / for-whom / when), the FDE builds across every layer and reports back what reality says; vs. the layer engineers, owns the breadth between layers, not the depth within one.
