Job Description

We're looking for a highly motivated Applied Machine Learning Scientist I to join our TDI AI/ML team. This role is primarily focused on Generative AI, including LLM-based and agentic solutions, while also offering opportunities to work on predictive machine learning use cases. You'll contribute across the end-to-end AI and machine learning lifecycle, including solution design, model development, evaluation, testing, validation, deployment, monitoring, and continuous improvement. You'll collaborate with business, technology, risk, governance, and implementation partners to help bring AI capabilities to life with measurable business impact.

This role offers an excellent opportunity to build hands-on machine learning expertise while gaining exposure to AI solution assessment, vendor model evaluation, implementation, and governance. You will work with business partners and experienced colleagues to advance the use of AI and Machine Learning at TDI while supporting the responsible adoption of both internally developed and third-party AI solutions.

Key Accountabilities

• Contribute to the development, deployment, and maintenance of Generative AI and predictive machine learning solutions for use cases such as customer and employee assistance, claims and underwriting support, operational automation, and risk assessment.
• Support the evaluation, implementation, testing, monitoring, and ongoing lifecycle management of both internally developed and third-party AI/ML solutions.
• Assist in assessing vendor-provided and out-of-the-box AI models, including their capabilities, limitations, performance characteristics, implementation considerations, and governance implications.
• Help translate well-defined business problems into analytical frameworks and collaborate with cross-functional teams to define success metrics, testing methodologies, and solution approaches.
• Contribute to model evaluation, documentation, A/B testing, validation support, and monitoring to help ensure model performance, fairness, stability, and compliance with Responsible AI principles.
• Communicate technical results clearly to technical and non-technical stakeholders and contribute to recommendations regarding model performance, implementation, and risk.

Strategic Thinking & Judgment

• Creative, out-of-the-box thinker with strong conceptual and problem-solving skills.
• Motivated to constantly identify innovative ways to enhance analytical solutions and AI implementation practices.
• Ability to investigate drivers of model performance variation and identify potential implementation or monitoring concerns with guidance.
• Interest in evaluating internally developed and vendor-provided AI solutions while considering business value, performance, and governance requirements.

Technical Competencies

• Proficiency in Python and modern machine learning frameworks and tools.
• Practical experience developing or evaluating machine learning or Generative AI solutions through professional work, internships, research, or substantial academic or personal projects.
• Understanding of model evaluation methodologies, experimentation, statistical testing, and performance monitoring.
• Familiarity with structured and unstructured data, feature engineering, and model interpretabi
