Formación

• 2+ years of industry experience in machine learning, applied AI, or software engineering with significant ML ownership.
• Strong hands-on coding ability and a track record of shipping production systems, not just prototypes or research projects.
• Experience in one or more of the following areas: LLM applications, NLP, search, retrieval, recommendations, evaluation frameworks, agent systems, or personalization.
• Comfort working across both modeling and product engineering details, including experimentation, quality measurement, and production iteration.
• Proficiency in common ML tooling and strong software engineering fundamentals in languages such as Python, Go, Java, or C++.
• A pragmatic, product-minded approach. You know when to use sophisticated ML techniques and when simple, reliable systems are the better answer.

Responsabilidades

• Build and improve ML and LLM-powered systems that raise the quality of Glean’s AI Assistant and autonomous agents across real user workflows.
• Design evaluation, benchmarking, and monitoring loops to measure assistant quality, model quality, and end-to-end system performance.
• Develop and iterate on signals, prompts, workflows, and model-driven logic that improve reasoning, planning, personalization, and task completion quality.
• Work across areas such as RAG, semantic search, recommendation-style systems, post-training or reinforcement learning, and agent orchestration where they materially improve product outcomes.
• Partner closely with product, design, and engineering teammates to understand customer pain points and ship high-quality production systems quickly.
• Contribute to the data and ML infrastructure needed to support robust experimentation, offline and online evaluation, and continuous model improvement.
