About the Role

As a Research Scientist, Human–AI Interaction, you will play a pivotal role in defining how AI systems support real human work by leading research at the intersection of Human–Computer Interaction (HCI), Large Language Models (LLMs), and task-level benchmarking.

You will operate at the frontier of human-centered AI evaluation, with a focus on understanding what people actually do to accomplish meaningful work—and how AI systems change, accelerate, or reshape that activity. Your research will define jobs-to-be-done benchmarks, comparative evaluation frameworks, and empirical methods for measuring human effort, time, quality, and outcomes when working with AI copilots. Additionally, the Handshake AI platform is an interface used by thousands of the top subject matter experts in the world to evaluate AI systems, and offers numerous interesting HCI / HITL-AI research questions that will drive large business impact.

You’ll set research direction, establish standards for measuring human activity in AI-mediated workflows, publish papers and open-source code, and lead the development of rigorous, scalable benchmarks that connect human work, AI assistance, and real economic value.

You will:

• Lead high-impact research on jobs-to-be-done benchmarks for AI systems, including:

  • Defining task taxonomies grounded in real professional and economic activities

  • Identifying what constitutes meaningful task completion, quality, and success

  • Translating qualitative work understanding into measurable, repeatable benchmarks

• Develop methods to measure human activity in AI-mediated workflows

• Design benchmarks to assess AI-as-a-collaborator/copilot, rather than autonomous agents / basic Q&A

• Design and run empirical studies of how people use AI to solve tasks, including:

  • Controlled experiments and field studies measuring task performance

  • Instrumentation for capturing fine-grained interaction traces and outcomes

• Drive strategy for professional-domain AI benchmarks, focusing on:

  • Understanding domain-specific workflows (e.g., analysis, writing, planning, coordination)

  • Grounding benchmark design in how work is actually performed, not idealized tasks

• Build and prototype AI systems and evaluation infrastructure to support research and Data production, including:

  • LLM-powered copilots and experimental tools used for task-level measurement

  • Benchmark harnesses that evaluate both model behavior and human outcomes

  • Data pipelines for analyzing human–AI interaction at scale

  • The human-in-the-loop experience for Handshake fellows to produce effective evaluations and training data for frontier models, through structured UI/UX interactions with these models.

• Collaborate closely with User Experience Research (UXR) to:

  • Leverage deep qualitative insights into real user behavior and workflows

  • Translate ethnographic and observational findings into formal research constructs

(This role is distinct from UXR and focuses on measurement, modeling, and evaluation.)

• Publish and present research that advances the field of human-centered AI benchmarking, with an expectation of regular contributions to top-tier venues such as CHI (Conference on Human Factors in Computing Systems), and related HCI and AI conferences.

Desired Capabilities

• PhD or equivalent experience in Human–Computer Interaction, Computer Science, Cognitive Science, or a related field, with a strong emphasis on empirical evaluation of interactive AI/LLM systems.

• 3+ years of academic or industry research experience post-PhD, including leadership on complex research initiatives and analyzing data from a real AI product.

• Strong publication record, with demonstrated impact in top-tier HCI venues — CHI experience required.

• Deep expertise in experimental design and measurement, particularly for:

  • Task performance and human activity

  • Comparative evaluation frameworks

  • Mixed-methods research grounded in real-world behavior

• Strong technical and coding skills, including:

  • Python and data analysis / ML tooling

  • Experience building experimental systems and benchmark infrastructure

  • Familiarity working with LLM APIs, agent frameworks, or AI-assisted tooling

• Proven ability to define and lead research agendas that connect human work, AI capability, and business or economic impact.

• Strong collaboration skills, especially working across research, engineering, product, and UXR teams.

Extra Credit

Experience developing benchmarks or evaluation frameworks for human–AI systems or AI-assisted productivity tools.

• Prior work on copilot-style systems, agentic workflows, or automation of professional tasks.

• Familiarity with workplace studies, CSCW, or socio-technical systems research.

• Contributions to open-source tools, datasets, or benchmarks related to task-level evaluation.

• Interest in how AI reshapes labor, productivity, and the future of work.
