• Implement and operate observability tooling using:

• • OpenTelemetry for distributed tracing

  • Metrics and dashboards (Prometheus, Grafana)

  • Logs and analytics (ELK or equivalent)

• Define and track ML-specific reliability signals, such as:

  • Model performance degradation

  • Data drift and feature anomalies

  • Prediction latency and failure rates

• Establish SLOs and alerting strategies for ML services in production.

Testing, Validation & Responsible AI Enablement

• Ensure testing and validation are embedded throughout the ML lifecycle, including:

  • Model validation and regression testing

  • Data and feature consistency checks

  • Deployment verification and rollback testing

• Integrate automated ML testing and quality gates into CI/CD pipelines.

• Support non-functional testing for ML systems, including:

  • Performance and scalability testing

  • Reliability and resilience testing

  • Security and access validation

• Partner with AI, data, and compliance teams to support responsible and compliant AI operations, including auditability, traceability, and explainability hooks (where required).

AI Platform Enablement & Cross‑Team Collaboration

• Enable data scientists and ML engineers to move models from experimentation to production efficiently and safely.

• Provide reusable tooling, templates, and paved paths for:

  • Experiment tracking

  • Model registry usage

  • Deployment and monitoring patterns

• Collaborate closely with:

  • Infrastructure Engineering (runtime, scaling, security)

  • DataOps Engineering (data pipelines, feature stores, data quality)

  • Product and analytics leaders to align ML capabilities to business outcomes.

Reliability, Incident Management & Continuous Improvement

• Own operational reliability for ML platforms and services.

• Lead response to ML-related production incidents, including:

  • Model failures or degradations

  • Data drift–driven issues

  • Pipeline or inference outages

• Conduct post-incident reviews and drive systemic improvements.

• Continuously improve MLOps maturity using SRE-inspired practices and metrics.

People Leadership & Engineering Ways of Working

• Set clear expectations for operational ownership, quality, and delivery.

• Coach engineers on:

  • MLOps best practices

  • Observability and reliability mindset

  • Secure and compliant AI operations

• Establish strong engineering discipline through design reviews, runbooks, documentation, and continuous learning.

• Act as the primary execution partner to the Director-level Commercial AI Analytics Solutions & Engineering Lead for ML operations and observability.

Here Is What You Need (Minimum Requirements)

• 8+ years of experience in ML engineering, MLOps, platform engineering, or related roles, with 3+ years of people leadership.

• Strong hands-on experience operationalizing ML systems in AWS or Azure environments.

• Proven expertise in:

  • MLOps pipelines and tooling (experiment tracking, model registry, deployment, monitoring)

  • CI/CD for ML workloads (e.g., GitHub Actions or equivalent)

  • Containerized and cloud-native ML runtimes

• Solid understanding of testing and validation for ML systems, including:

  • Model regression and performance testing

  • Data and feature validation

  • Deployment and rollback verification

• Strong experience implementing observability and reliability practices using tools such as OpenTelemetry, Prometheus, Grafana, and ELK.

• Demonstrated experience with DevSecOps and secure SDLC for AI/ML systems, including secrets management and access controls.

• Proficiency in programming and scripting (e.g., Python, Bash, SQL; familiarity with ML frameworks).

• Strong communication and collaboration skills; ability to deliver outcomes through teams and influence cross-functionally.

Bonus Points If You Have (Preferred Requirements)

• Master's degree in Computer Science, Data Science, AI/ML, or related field.

• Experience with MLOps platforms and tools (e.g., MLflow, Kubeflow, feature stores).

• Background in data drift detection, model monitoring, and ML reliability engineering.

• Familiarity with responsible AI, governance, or regulated environments.

• Relevant certifications:
