Principal Full-Stack AI Engineer - Platform Architect

Full-time
On-site
Level: Principal / Staff (individual contributor)
The most senior engineer on the team and the technical anchor for the platform. You design the reference architecture and personally build the hardest pieces - the lifecycle registries, the AI control-plane services that plug into the enterprise gateway, and the harness/memory services - setting the patterns the rest of the pod extends.
What You Will Do • Own the paved road - the reference architecture and the reusable registration pattern behind every asset (registration schema, semantic metadata, I/O contract, execution binding, governance constraints) so the agent, model, tool, workflow and skill registries all share one shape. • Personally build the hardest pieces - the lifecycle registries; the AI control-plane services that plug into the enterprise gateway (registries, PII/PHI and prompt-injection scanning as a gateway policy, token-aware metering and multi-vendor cost attribution, AI trace/observability, and the multi-provider model-abstraction layer behind its fail-over); and the harness/memory & skills services. • Build the agent-building paved road - the scaffolds, patterns and sub-agent topologies the team uses to stand up new agents fast, including the end-to-end builder agent (architect $B"*(B provision $B"*(B implement $B"*(B test sub-agent $B"*(B deploy $B"*(B post-process $B"*(B log). • Deliver platform features as agents where it fits (e.g. a lifecycle-management agent, a skills-planning agent) - so the platform builds and operates itself, not just exposes CRUD APIs. • Enforce portability in code - containerize everything; standardize lineage on MLflow + metadata, telemetry on OpenTelemetry, table formats on Delta UniForm / Iceberg, and open-weight serving on vLLM/Ray/DeepSpeed. • Set the engineering bar - testing, CI/CD, IaC and security-by-default standards; review the team's hardest designs and pull requests; mentor the senior engineers. • Build with AI and build agents end to end - like everyone on the team.
What We're Looking For - Required Qualifications • Principal-level full-stack - you build production services end to end (backend, APIs, and enough frontend to ship the registry and dev UIs) and you own systems in production. • Distributed systems & platform engineering - Kubernetes, containers, IaC (Terraform), CI/CD, secrets/RBAC, and multi-tenant service design. • Cloud depth with a portable mindset - strong on GCP (GKE, Vertex AI, IAM, VPC Service Controls, BigQuery), but standards-first by instinct. • Hands-on GenAI / agentic engineering - LLM and agent runtimes, multi-agent and sub-agent orchestration, A2A and MCP/tool integration, retrieval/RAG, memory systems, and end-to-end builder agents. • Security & governance by design - identity-aware access, PII/PHI handling, runtime guardrails, gateway/policy-as-code, and audit/observability. • AI-assisted engineering - fluent and effective with AI coding tools (Cursor, Claude Code, Copilot, Windsurf or equivalent), and able to define the patterns and review discipline the team uses with them. • Strong software engineering background - strong Python (and typically one of Go / Java / TypeScript).
