Overview
The Junior AI 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 , 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 OpenTelemetry (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 AgentForce, ServiceNow, 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 using standardized eval harnesses — documenting results and feeding findings into quality improvement cycles.
- Develop automated quality reports and quality metric dashboards for stakeholder review, surfacing trends and anomalies in agent behavior over time.
- Memory, Skills, MCP & Harness Engineering Observability (10%)
- Instrument agent memory operations (read/write latency, cache hit rates, memory drift) across episodic, semantic, and working memory backends within the assigned scope.
- Add trace instrumentation to MCP server interactions — tagging tool registrations, skill invocations, context injections, and result returns with semantic OTEL attributes.
- Capture harness execution telemetry for self-evolving and RL systems — logging reward signals, policy update events, environment transitions, and convergence indicators.
- Monitor skill eval harness execution pipelines — detecting flaky evals, environment setup failures, and result inconsistencies that could mask real capability regressions.
- Data Science & Python Engineering (10%)
- Write production-grade Python for observability tooling — custom OTEL exporters, signal aggregators, anomaly detectors, and data transformation pipelines — adhering to team engineering standards.
- Apply basic statistical and data science methods to telemetry data — time-series analysis, threshold tuning, distribution characterization — to improve signal quality and alerting precision.
- Contribute to Python SDK and library development that simplifies OTEL onboarding for agent developers across the organization.
- Participate in code reviews, apply test-driven development practices, and continuously improve the quality and maintainability of the observability codebase.
- Agent Fleet, Physical AI & Multi-Modal Observability (5%)
- Implement telemetry for agent fleet coordination — capturing spawn/termination events, inter-agent communication traces, load distribution metrics, and fleet health indicators.
- Contribute to observability instrumentation for physical AI pipelines (edge inference, sensor fusion, robotics control loops) as directed — focusing on latency, reliability, and data quality signals.
- Add OTEL instrumentation to multi-modal model pipelines — tracing vision, audio, and text input processing stages and capturing cross-modal alignment quality signals.
- Agentic Marketplace, Registry & A2A / UCP / AP2 Observability (5%)
- Instrument the Agentic Marketplace and Agent Registry with usage telemetry — tracking agent invocations, capability health scores, adoption trends, and dependency relationships.
- Implement protocol-level observability for A2A (Agent-to-Agent), UCP, and AP2 communication flows — capturing message latency, error rates, retry patterns, and trust boundary crossings.
- Contribute to Marketplace Observability Dashboard development — building data connectors, metric calculations, and visualization components.
- Collaboration, Integration & Continuous Learning (5%)
- Collaborate closely with AI platform engineers, data scientists, SRE, and product teams to gather requirements, align on telemetry standards, and resolve integration friction.
- Participate in agile ceremonies — sprint planning, stand-ups, retrospectives — contributing to estimation, dependency identification, and delivery transparency.
- Stay current with emerging observability frameworks, OTEL specifications, agent communication protocols, and AI safety research — sharing learnings with the team regularly.
- Contribute to internal documentation, engineering wikis, and onboarding guides for the observability platform.
