Position Overview:

As a Senior Machine Learning Engineer at Fractal Analytics, you will be at the forefront of building and deploying AI-driven solutions that address critical business challenges across industries. You will work with cutting-edge AI platforms to develop both custom and pre-built enterprise applications. These applications include use cases such as demand forecasting, asset reliability, predictive maintenance, inventory optimization, supply chain planning, anomaly detection, operational intelligence, and other applied AI solutions.

This is a senior delivery and ownership role where you will be responsible for leading machine learning and data science workstreams from business problem definition through model development, production deployment, and client adoption. The right candidate can operate independently, guide technical decisions, work directly with stakeholders, and ensure AI solutions are practical, scalable, and valuable in real business environments.

Responsibilities Include:

• Own end-to-end machine learning delivery for proprietary AI platform-based solutions, from problem framing through production implementation.
• Partner with internal and vendor AI teams along with client stakeholders to translate business needs into analytical approaches, model requirements, and measurable success criteria.
• Lead the development of machine learning, statistical, forecasting, optimization, and AI models for enterprise-scale applications.
• Evaluate data readiness, define feature strategies, identify data quality risks, and recommend practical paths to production.
• Design modeling approaches that balance accuracy, explainability, reliability, scalability, and business usability.
• Collaborate with engineering, product, and platform teams to integrate models into various client AI applications and operational workflows.
• Establish and follow best practices for experimentation, validation, documentation, reproducibility, monitoring, and model governance.
• Support deployed solutions by monitoring performance, diagnosing issues, and driving continuous improvement.
• Communicate technical findings, assumptions, tradeoffs, and recommendations to both technical and non-technical audiences.
• Provide senior-level guidance to junior data scientists, engineers, and analysts contributing to project delivery.
• Stay current with developments in machine learning, Generative AI, time series modeling, optimization, and enterprise AI platforms, applying new methods where they improve outcomes.

Qualifications:

• MS or PhD in Computer Science, Data Science, Statistics, Mathematics, Engineering, Operations Research, or a related quantitative field.
• 5+ years of applied machine learning, data science, or AI experience in a professional setting.
• Demonstrated experience owning projects or major workstreams from initial problem definition through delivery.
• Excellent programming skills in Python to include strong overall OOP experience.
• Strong proficiency with machine learning and data science tools such as Scikit-learn, PyTorch, TensorFlow, pandas, NumPy, XGBoost, or similar frameworks.
• Broad knowledge of machine learning and AI methods, including when to apply different approaches and what tradeoffs to consider.
• Project experience in several of the following areas: supervised learning, unsupervised learning, time series forecasting, deep learning, operations research, optimization, anomaly detection, or Generative AI.
• Familiarity with the machine learning lifecycle, including experimentation, versioning, deployment, monitoring, governance, and retraining.
• Experience with production-oriented ML tools or workflow platforms such as MLflow, Airflow, Kubeflow, Databricks, or similar.
• Familiarity with scalable data and AI technologies such as Spark, distributed processing, streaming systems, or cloud-based ML services.
• Prior exposure to AWS, Azure, or Google Cloud, especially AI/ML services, is advantageous.
• Ability to lead independently while collaborating effectively with client, product, engineering, and delivery teams.
• Strong communication skills, including the ability to explain complex analytical work clearly to business stakeholders.
• High ownership mindset, strong judgment, practical problem-solving ability, and a desire to create measurable business impact.

Preferred Qualifications:

• Hands-on experience with the C3 AI platform.
• Experience working in an embedded client environment, partner delivery model, enterprise SaaS implementation, or AI platform delivery role.
• Experience delivering AI solutions for large enterprises or Fortune 500 clients.
• Domain experience in manufacturing, energy, utilities, supply chain, aerospace, telecommunications, financial services, or other operationally complex industries.
• Experience with demand forecasting, asset reliability planning, predictive maintenance, inventory optimization, or supply chain optimization.
• Experience mentoring junior team members or leading small technical teams.
