Job Title: Lead Machine Learning Engineer
Experience: 5 or more years of core machine learning engineering experience

About the Job:
We are looking for a Lead Machine Learning Engineer to improve the reliability of Tonik's ML deployment and operations. You will remain a hands-on senior individual contributor, own MLOps project or topic areas, and review others' work.

Your priority is to reduce deployment mistakes and establish engineering practices that make frequent scorecard safe and repeatable. You will support real-time and batch inference, including underwriting and offer-generation workflows, while building reusable controls that can be adopted across the ML estate.

Job Responsibilities:
• Assess the current ML delivery process, identify recurring failure modes and own a practical MLOps improvement roadmap. Personally implement priority changes and demonstrate their effect on release quality, recovery time and delivery effort.

• Design and build reliable real-time and batch inference workflows using Python, SQL, APIs and cloud services.



Work within Tonik's GCP and BigQuery workplace and API-based model serving architecture, including FastAPI, Docker and Kubernetes.

• Introduce repeatable release controls: versioned model artifacts, feature schemas and configuration; separate environments; automated tests; peer review; approval evidence; deployment checks; and rollback procedures.

• Prevent training-serving inconsistencies through explicit feature contracts, dependency pinning and version alignment. Reconcile production scores against approved reference outputs, including missing-data handling, score ranges, stacked models and segment routing.

• Build CI/CD pipelines for ML that test feature transformations, inference logic, APIs and integrations. Add regression datasets, schema checks and release validation so changes cannot silently alter approved scoring behaviour.

• Establish model registries, experiment and artifact traceability, reproducible pac
