Analyst – Applied Validations
Simile
Enterprise AI platform simulating human behavior
Pilots don't train with real passengers. Actors don't rehearse with real audiences. Yet, the most consequential decisions in society are often pushed straight to production.
Simile is changing that. We have built the first AI simulation of society, populated by generative agents based on real humans. Our research pioneered the field of AI-based simulation, proving it is possible to model human behavior with high accuracy. Today, we are developing a Foundation Model to predict human behavior in any situation, at any scale.
We have raised $300M in total funding, with a $2B post-money valuation in our latest round. Our investors include Greenoaks, Index Ventures, Hanabi, A*, Bain Capital Ventures, Factory, CVS Health Ventures, and Definition.
At Simile, accuracy is the product. Enterprise buyers want proof that Simile matches what their customers actually say and do, and as an Applied Validations Analyst, you will own that proof. You'll design and run customer validations and backtests that compare Simile's simulated results against real-world ground truth, then diagnose gaps, explain what the evidence supports, and identify opportunities to improve performance.
You'll work alongside Solutions Consultants and Deployments, and be deeply embedded with our Modeling, Evals, and Data teams. You'll turn one-off studies into repeatable, scalable workflows that build customer trust in a new category of AI. You'll identify patterns across customer validations and work with Modeling, Evals, Data, and Product to turn those findings into improvements, and test whether those improvements address the gaps.
This is a hands-on individual contributor role for someone who enjoys writing code, investigating data, and learning new methods while working at the pace of customer engagements.
Study Scoping: Scope validation and backtest studies with Solutions Consultants, Deployments, and customers. Pick the right use case, agree on metrics and success criteria up front, and flag studies that won't produce a meaningful comparison. Guide teams on which validation approaches are appropriate given current model and product capabilities.
Simulation & Comparison: Run simulations and compare them against human ground truth using industry standard evaluation metrics.
Diagnosing Misses: Break down gaps by segment and population to determine drivers of differences around methodology, model, data, or sampling. Identify recurring patterns across validations to distinguish isolated gaps from systematic gaps.
Closing the Loop: Translate validation gaps into reproducible examples and concrete recommendations for Modeling, Evals, Data, and Product. Partner with these teams on follow-up experiments, evaluation coverage, and data, and retest whether changes address the gaps.
Reusable Tooling: Build Python pipelines, API-driven experiments, and LLM skills for repeatable validation loops. .
Customer Readouts: Write clear readouts showing where the model is strongly aligned and where it is more directional, and present them to technical and business stakeholders.
Statistics & Analytical Judgment: A solid foundation in statistics, including sampling, variability, correlation, and bias. You can question data quality, recognize misleading comparisons, investigate differences across populations and segments, and assess whether conclusions are supported by the evidence.
Learning & Iteration: Demonstrated ability to learn unfamiliar methods and tools quickly, investigate unexpected results, and improve an approach through structured experimentation. You are motivated to build expertise in customer validations and backtesting.
Technical & AI-Native Workflow: Ability to use Python and APIs to analyze data and run reproducible experiments, including using Claude Code, Codex, or similar coding agents to accelerate the work. You can review and validate the outputs these tools produce.
Communication & Commercial Judgment: You can turn analysis into a clear narrative, explain results and limitations to technical and business audiences, and connect findings to customer decisions and priorities.
Collaboration & Follow-Through: You can translate findings into actionable recommendations, work with Modeling, Evals, Data, and Product teams to address gaps, and document lessons that help others move faster.
Validation & Model Improvement: Experience running backtests and evaluating predictive models.
Evaluation Methods: Familiarity with holdout datasets, data leakage, and testing whether improvements generalize to unseen examples.
Human Study & Measurement Methods: Familiarity with survey & human study design, panel sampling, distributional comparisons such as TVD, choice-based methods, or differences between stated intent and observed behavior.
Research Background: Experience in behavioral research, market research, consumer insights, survey science, or a research-agency analytics team.
Survey Platforms: Experience with Qualtrics or similar survey platforms and panel providers.
Customer-Facing Technical Work: Experience in applied data science, technical consulting, or presenting analytical findings to customers.

Simile builds AI models that simulate human behavior to forecast how individuals and groups will respond to scenarios using generative agents grounded in real data. The platform runs simulations of events like product launches, policy changes, or earnings calls to support decision-making. It differentiates itself by grounding agents in hundreds of interviews and behavioral science, combining Stanford-backed research with enterprise-focused decision intelligence. Its goal is to help organizations test decisions and forecast outcomes before acting, reducing uncertainty in strategic planning.
