| name | ml-infrastructure-engineer-safeguards |
| description | Guides ML infrastructure for safeguards—inference gateways, model serving (GPU/CPU), guardrail and
moderation pipelines in the request path, policy enforcement hooks, safety observability, rollout
of filter/model versions, and reliability of the protected inference plane.
Use when designing or operating safeguard layers on LLM/ML endpoints, deploying classifiers or
moderation services, wiring pre/post-filters, scaling safety microservices, or debugging
block-rate/latency regressions on the safety path—not for corporate AI policy (ai-risk-governance),
building RAG/agents (ai-engineer), adversarial test campaigns (ai-redteam), general CI/CD
(devops), app perf profiling (performance-engineer), or DC facility compute programs
(data-center-compute-supply-efficiency). Safeguard R&D: ml-research-engineer-safeguards;
privacy research: privacy-research-engineer-safeguards.

ML Infrastructure Engineer, Safeguards
When to Use
- Design inference gateway with safeguard stages (auth, rate limit, pre-filter, model, post-filter)
- Deploy model servers — GPU pools, replicas, autoscaling, health checks
- Operate moderation/classifier services (hosted or self-hosted) in production
- Configure policy runtime — thresholds, categories, block vs rewrite vs escalate
- Instrument safety metrics — block rate, false positive sampling, safety-path latency
- Roll out safeguard model versions — canary, rollback, config flags
- Plan capacity for safety + main model (queueing, shedding, degradation modes)
- Integrate human review queues and appeal flows at infrastructure boundary
- Debug production incidents — safety service down, filter bypass, p99 on guard path

Core Workflows
1. Inference and serving platform
Gateways, model servers, scaling.
See references/inference_serving_platform.md.
2. Safeguards request path
Pre/post filters, ordering, failure modes.
See references/safeguards_request_path.md.
3. Policy runtime enforcement
Thresholds, actions, human loop hooks.
See references/policy_runtime_enforcement.md.
4. Safety observability
Metrics, logs, sampling, privacy.
See references/safety_observability.md.
5. Model and config rollout
Versions, canaries, kill switches.
See references/model_version_rollout.md.
6. Capacity and reliability
GPU, degradation, DR.
See references/capacity_reliability.md.
Outputs
- Architecture diagram — request path with safeguard stages and dependencies
- Runbook — deploy, rollback, scale, incident playbooks for safety services
- Config spec — policy thresholds, model IDs, feature flags per environment
- SLO sheet — availability and p99 for gateway + each safety stage
- Capacity plan — GPU/CPU headroom, QPS limits, degradation matrix
- Rollout plan — canary criteria tied to block-rate and error budgets
Principles
- Fail closed for high-risk tiers — when safety path unavailable, default deny or safe response per policy
- Latency budgeted — safety is part of user-facing SLO, not best-effort
- Observable decisions — log decision codes, not raw harmful content in clear text
- Version everything — policy config, classifier weights, and gateway routing independently
- Test in prod-like path — staging must run full safeguard chain, not model-only
