The **Senior Synthetic Data Specialist** designs, builds, and governs synthetic data capabilities that enable machine learning development, testing, analytics, and product experimentation when real data is limited, sensitive, biased, or operationally difficult to access. This role blends applied ML, data engineering, privacy engineering, and data quality practices to produce synthetic datasets that are **useful, safe, explainable, and reproducible**.

The **Senior Model Evaluation Specialist** designs, executes, and operationalizes rigorous evaluation of machine learning (ML) and generative AI models to ensure they are accurate, reliable, safe, and fit for production use. This role turns ambiguous product and risk questions (“Is the model good enough?”, “Is it safe?”, “Will it regress?”) into measurable criteria, repeatable test suites, and decision-ready insights.

The **Senior LLM Trainer** is a senior individual contributor in the **AI & ML** organization responsible for improving large language model (LLM) behavior through high-quality training data, preference signals, evaluation design, and alignment techniques (e.g., instruction tuning and RLHF-style workflows). This role sits at the intersection of product intent, linguistic/semantic quality, and ML training operations—turning ambiguous user needs and policy constraints into measurable model improvements.

The Model Evaluation Specialist designs, executes, and operationalizes rigorous evaluation of machine learning (ML) and increasingly large language models (LLMs) across offline benchmarks, pre-production testing, and post-deployment monitoring. The role exists to ensure models are **measurably effective, safe, reliable, and aligned with product intent**, and that model quality is assessed consistently over time as data, prompts, and user behavior evolve.

The **LLM Trainer** is a specialist individual contributor responsible for improving the usefulness, safety, and reliability of large language model (LLM) behavior through high-quality training data creation, annotation, preference/ranking workflows (e.g., RLHF-style data), evaluation design, and systematic error reduction. The role sits at the intersection of **applied AI**, **data operations**, and **model quality**, turning ambiguous product expectations (“be helpful and safe”) into measurable training signals and repeatable processes.

The **LLM Evaluation Specialist** designs, runs, and operationalizes evaluation systems that measure the quality, safety, and business fitness of Large Language Model (LLM) capabilities used in products and internal platforms. The role exists to ensure that LLM-powered features are **measurable, comparable, reliable in production**, and aligned with user needs and organizational risk posture—especially as models, prompts, tools, and data change rapidly.

The **Lead Machine Learning Specialist** is a senior individual contributor who designs, delivers, and operationalizes machine learning solutions that materially improve product capabilities and internal decision-making. The role combines advanced applied ML expertise with technical leadership across the full lifecycle—problem framing, data and feature strategy, model development, evaluation, deployment, monitoring, and iteration—while ensuring solutions are reliable, scalable, and responsibly governed.

The Lead LLM Trainer is a senior specialist responsible for improving the quality, safety, and task performance of large language models (LLMs) through systematic training data strategy, human feedback programs, evaluation design, and iterative model improvement cycles. The role bridges applied ML engineering and human-in-the-loop operations, turning ambiguous product needs (e.g., “make the assistant more helpful and less risky”) into measurable training objectives, datasets, and acceptance criteria.

The **Lead AI Governance Specialist** designs, operationalizes, and continuously improves the company’s governance system for AI/ML—ensuring models and AI-enabled features are **safe, compliant, auditable, and aligned with internal standards** from ideation through retirement. This role translates external expectations (regulation, customer requirements, industry frameworks) into **practical, engineering-friendly controls** that can be embedded into product development and MLOps.

The **Associate Search Relevance Specialist** improves the quality of on-site or in-product search results by analyzing user behavior, evaluating ranking outcomes, curating relevance signals (e.g., synonyms, boosts, rules), and supporting ML-driven search optimization. This role sits at the intersection of information retrieval (IR), analytics, and product operations—turning search data into practical improvements that increase user satisfaction and business conversion.

The **Associate Robotics Specialist** is an early-career, hands-on specialist who supports the development, testing, integration, and reliable operation of robotics software components within an **AI & ML** organization. The role focuses on building and validating robotics capabilities (e.g., perception, navigation, sensor integration, simulation-to-real workflows, and fleet telemetry) under the guidance of senior robotics engineers and applied ML leaders.

The **Associate Responsible AI Specialist** supports the safe, ethical, and compliant design, development, deployment, and monitoring of AI/ML systems in a software or IT organization. This role translates Responsible AI (RAI) principles into practical checks, documentation, testing, and operational controls that product and engineering teams can adopt without slowing delivery.

The Associate LLM Trainer is an early-career specialist role responsible for improving the quality, safety, and usefulness of large language model (LLM) outputs through structured data annotation, response evaluation, prompt set development, and feedback-driven iteration. The role focuses on executing well-defined training and evaluation workflows (e.g., preference ranking, instruction-following checks, factuality validation, safety tagging), producing high-quality labeled datasets and insights that directly influence model behavior.

The **Associate AI Governance Specialist** supports the company’s responsible AI and AI risk management program by helping teams operationalize governance controls across the AI/ML lifecycle— from data intake and model development through deployment and monitoring. The role focuses on **execution, evidence collection, documentation quality, control testing support, and stakeholder coordination** to ensure AI systems meet internal standards and external expectations for safety, privacy, security, transparency, and regulatory readiness.

The **AI Trainer** is a specialist individual contributor responsible for improving AI model behavior through high-quality human feedback, structured data labeling, evaluation design, and iterative refinement of training datasets and guidelines. This role sits at the intersection of product intent, user experience, and model performance—translating ambiguous real-world inputs into consistent training signals that materially improve accuracy, safety, and usefulness.

The **AI Governance Specialist** designs, operationalizes, and continuously improves the policies, controls, and workflows that ensure AI systems are **safe, compliant, auditable, and aligned to company risk appetite**. The role partners with engineering, data science, security, legal, privacy, and product teams to embed governance into the AI/ML lifecycle—from idea intake and data sourcing through model deployment, monitoring, and retirement.
