Descripción del empleo

About Glean: Glean is the Work AI platform that helps everyone work smarter with AI. What began as the industry’s most advanced enterprise search has evolved into a full-scale Work AI ecosystem, powering intelligent Search, an AI Assistant, and scalable AI agents on one secure, open platform. With over 100 enterprise SaaS connectors, flexible LLM choice, and robust APIs, Glean gives organizations the infrastructure to govern, scale, and customize AI across their entire business - without vendor lock-in or costly implementation cycles.At its core, Glean is redefining how enterprises find, use, and act on knowledge. Its Enterprise Graph and Personal Knowledge Graph map the relationships between people, content, and activity, delivering deeply personalized, context‑aware responses for every employee. This foundation powers Glean’s agentic capabilities - AI agents that automate real work across teams by accessing the industry’s broadest range of data: enterprise and world, structured and unstructured, historical and real‑time. The result: measurable business impact through faster onboarding, hours of productivity gained each week, and smarter, safer decisions at every level.Recognized by Fast Company as one of the World’s Most Innovative Companies (Top 10, 2025), by CNBC’s Disruptor 50, Bloomberg’s AI Startups to Watch (2026), Forbes AI 50, and Gartner’s Tech Innovators in Agentic AI, Glean continues to accelerate its global impact. With customers across 50+ industries and 1,000+ employees in more than 25 countries, we’re helping the world’s largest organizations make every employee AI‑fluent, and turning the superintelligent enterprise from concept into reality.If you’re excited to shape how the world works, you’ll help build systems used daily across Microsoft Teams, Zoom, ServiceNow, Zendesk, GitHub, and many more. You'll be deeply embedded where people get things done. You'll ship agentic capabilities on an open, extensible stack, with the craft and care required for enterprise trust, as we bring Work AI to every employee, in every company.

About the Role:

The bottleneck in building reliable and useful AI systems isn’t writing code anymore. It’s knowing what good looks like, applying that knowledge and experience from production usage into building rigorous evals, and using those evals to guide continuous product self‑improvement loops.

As the Tech Lead Manager of AI Evaluations, you will lead a team of applied AI scientists and engineers and build the evaluation strategy and platform that helps Glean ship delightful and reliable AI experiences. You will make evaluation a continuous part of how we develop and operate models, harnesses, assistants, agents, and other AI products at Glean.

You’ll guide the team in translating emerging AI/ML research into reliable evaluation systems, build scalable, efficient and reusable eval infrastructure and trusted quality signals, and work across R&D, product, and marketing teams to turn evaluation results into better products and customer outcomes.

You will:

• Own the AI evaluation eng roadmap and technical direction end to end: from defining what success means and building the evaluation platform to integrating results into release and product decisions.
• Build scalable, reusable evaluation infrastructure for datasets, experiments, graders, trace capture and replay, result analysis, and dashboards. Make evaluations reproducible, versioned, cost‑aware, and easy for product and engineering teams to use.
• Create and maintain representative evaluation sets from expert‑curated examples, appropriately governed production signals, synthetic cases, and historical failures. Cover common workflows, edge cases, long‑tail requests, adversarial inputs, and important user and domain slices; protect held‑out acceptance sets from tuning leakage.
• Define a balanced quality measurement system for AI products, including correctness, groundedness, retrieval and context relevance, completeness, instruction following, citation quality, user preference, and task success. For agents, evaluate tool selection and arguments, multi‑step trajectories, policy compliance, recovery, and final task state, not just the final response.
• Develop a fit‑for‑purpose mix of deterministic checks, model‑based graders (including LLM‑based autograders), and human evaluation. Establish clear rubrics; validate and calibrate automated judges against human judgments; and measure evaluator reliability and limitations so teams can trust and interpret scores.
• Integrate evaluation into development and operations: fast CI regression checks, broader pre‑release suites, model and prompt comparisons, and sampled production evaluation. Build feedback loops from user feedback and production traces into new test cases, and use monitoring, canaries, and experiments to detect regressions and drift.
• Make quality tradeoffs measurable by connecting evaluation outcomes to latency, reliability, and cost. Help teams diagnose failures by slice and trace, prioritize improvements, and make evidence‑based decisions about models, routing, prompts, and system changes.
• Build and lead a high‑performing team of applied AI scientists and engineers; coach and develop team members. Partner closely with product, infrastructure, security, and application teams to align evaluation standards and deliver the highest‑impact work.

About you:

• 10+ years of experience in software engineering, ML infrastructure, data systems, or a related technical field. Experience must include building and operating production systems.
• 5+ years of engineering or applied AI team management experience, with a track record of technical leadership, developing engineers and scientists, and delivering cross‑functional projects.
• Hands‑on experience designing, building, or operating evaluation systems for LLM/GenAI products, including model‑based evaluators or autograders; practical understanding of how to assess model, retrieval/RAG, assistant, or agent behavior.
• Familiarity with evaluation methods and tradeoffs: curated and production‑derived datasets, benchmark creation, deterministic metrics, rubric‑based and pairwise judgments, human review, judge validation and calibration, human‑model alignment, and statistical analysis of results.
• Understanding of agent evaluation, including tool calling, multi‑turn behavior, trajectory quality, task completion, and recovery from errors; experience with safety testing or red teaming is a plus.
• Strong coding ability in Python or another production language, with sound engineering fundamentals in testing, APIs, data modeling, and reliable distributed systems.
• Experience building scalable data and developer platforms, experiment pipelines, or CI/CD integrations; familiarity with cloud infrastructure, Kubernetes, data stores, and observability is beneficial.
• Strong judgment about measurement quality, including dataset representativeness, judge calibration, reproducibility, uncertainty, and the risk of optimizing to a narrow metric.
• Knowledge of public benchmarks across domains and capabilities is a plus.
• Product‑mindful and collaborative: able to translate ambiguous quality goals into clear measures, communicate findings to technical and non‑technical audiences, and influence roadmaps across teams.
• MS/PhD in Computer Science, AI or a related field.
