Role
Who you are
- Strong foundational familiarity with the full AI product stack

You will work across applied research and engineering to solve many open problems in AI, including:
- Designing AI agents to navigate the digital world and perform increasingly valuable units of work for our users
- Training action and decision models that determine, based on complex multimodal states, how to accomplish user-specified objectives
- Providing consistently excellent experiences across desktop, mobile, headless cloud, and other environments through flexible abstractions and frictionless backgrounding
- Developing permission architectures, payload classifiers, and other methods to implement secure-by-design agentic capabilities
- Designing optimal data representations and modes of interaction between agents and their environments
- And much, much more
- Drive cutting-edge AI capabilities across multiple layers of a rapidly growing product in the AI agents space
- Develop and leverage cutting-edge AI models, infrastructure, and browser technologies to advance the capability frontier and scale those capabilities for a rapidly growing userbase
- Ensure a high craft and quality bar, in both AI agent performance and user experience
- Collaborate with fellow engineers, designers, product managers, data scientists, and others across the company to integrate core Perplexity functionality into our frontier agentic products and vice-versa
- Contribute to product reliability, code quality, AI evaluation, testing, and maintenance across the broader team
Our take
As AI continues to drive changes in both business operations and day-to-day lives, Perplexity delivers an intelligent search engine powered by conversational AI, to improve search outcomes and "unlock the power of knowledge" for all.
Reaching impressive heights of 22M monthly visits, Perplexity's "ask anything" method of search is clearly a popular one. And what sets it apart from other search engines is in its answers, which are concise and fully cited, responding to the user query rather than simply providing a place in which they can scroll to find it themselves.
The company has raised substantial funding, with contributions from former execs at companies like OpenAI, Meta, and Quora, demonstrating the interest that it has drummed up in the space. Having doubled its annual recurring revenue between 2023 and 24, this investment has allowed Perplexity to continue building out its product, and accelerate growth into the future.
