Member of Technical Staff (Model Behavior Architect)

$180k - $260k

Perplexity

Perplexity is looking for a Model Behavior Architect to help shape our answer engine. This role collaborates with our research, design, and engineering teams to align model behavior with product goals. Responsibilities Design, refine, and implement context engineering strategies to guide model behavior across use cases. Identify inconsistencies in model outputs through well-designed research and evaluation projects. These projects may be either for internal or production-facing systems. Develop automated and semi-automated pipelines for evaluating agent effectiveness at scale. Stay current with the latest alignment and evaluation techniques from both industry and academia. Qualifications Demonstrated passion for AI and can share specific, related projects you're proud of. Familiar with Python. While this is not strictly a production engineering role, you will need to be able to prototype and debug systems at scale and quickly understand the various components that go into answer generation. Candidates should have high-level understanding of LLMs, training, RL. We’ve seen excellent candidates who background in philosophy, psychology, linguistics, data science, or related fields. Excellent communication skills, particularly in teaching complex concepts. Creative problem-solving abilities with a "hacker spirit" for solving puzzles. Compensation Range: $180K - $260K #J-18808-Ljbffr Perplexity
