Principal AI Architect​/Engineer

Overview

The AI Platform/Observability Architect is an execution-focused engineer who designs, builds, and operates observability capabilities within a defined domain of the enterprise AI observability platform. Working under the strategic direction of the Senior AI Observability Architect (L11), this role translates architecture blueprints into production-grade instrumentation, telemetry pipelines, dashboards, quality gates, and safety signals across agentic AI systems.

The junior architect is a hands-on engineer who codes, integrates, tests, and iterates - owning feature-level delivery within one or more specialization tracks while developing a growing understanding of the full observability platform. They are a technical practitioner first, with an emerging architect mindset.

Responsibilities

Observability Platform Engineering & OTEL Integration (25%):

• Implement Open Telemetry (OTEL) instrumentation within assigned agent frameworks or platforms - including custom exporters, span enrichers, semantic conventions, and context propagation hooks.
• Build and maintain telemetry pipeline components (collectors, processors, exporters) that route metrics, logs, traces, and semantic signals to central observability backends.
• Integrate OTEL with enterprise agentic platforms as assigned - which may include Salesforce Agent Force, Service Now, Microsoft Agent 365, or internal frameworks - following architecture blueprints set by the L11.
• Develop and maintain observability dashboards, alerting rules, and SLO/SLA definitions for the assigned sub-domain, ensuring signal quality and low false-positive rates.
• Participate in on-call rotations and incident response for the observability platform - contributing to RCA documentation and runbook improvement.
• Write unit, integration, and end-to-end tests for all telemetry components; maintain >80% test coverage across owned services.

Safety, Security & Red Teaming Support (15%):

• Instrument safety-critical signal capture within assigned pipelines - including guardrail trigger rates, policy violation events, prompt injection detections, and hallucination flags.
• Support red team exercises by building observability hooks that capture adversarial test results, attack surface telemetry, and behavioral deviation signals in real time.
• Implement secure trace handling for sensitive AI decision events - applying data masking, PII redaction, and audit-log retention policies as defined by the security architecture.
• Assist in maintaining the Security Observability Playbook - documenting findings, updating escalation paths, and contributing to incident classification procedures.
• Monitor agent-to-agent protocol traffic (A2A, UCP, AP2) for anomalous communication patterns and flag deviations for review by the L11 architect and security team.

Responsible AI (RAI) & Governance Signal Instrumentation (10%):

• Implement RAI signal collectors within assigned agent workflows - capturing fairness indicators, bias detection outputs, explainability scores, and content safety classifications.
• Maintain RAI telemetry pipelines and ensure data quality, completeness, and timeliness of governance signals feeding into compliance dashboards.
• Contribute to audit-readiness work by ensuring all AI decision traces within the assigned domain include required governance metadata and are retained per policy.
• Support gap analyses by comparing current RAI signal coverage against governance framework requirements and flagging coverage gaps to the L11.

Quality Engineering for Agentic Solutions - Post Go-Live & Continuous QE (15%):

• Build and maintain quality gate components within CI/CD pipelines - using observability data to detect performance regressions, behavioral drift, and SLA breaches before they reach production.
• Instrument and monitor Skill Evaluations (evals) across the Memory, Skills, and MCP harness stack - collecting eval results, tracking pass/fail trends, and alerting on regression thresholds.
• Implement continuous quality monitoring for post-go-live agentic solutions - tracking agent success rate, tool-call fidelity, latency distributions, and user outcome proxies.
• Conduct structured testing of new agent capabilities…
