Perplexity is seeking an energetic engineer to join our highly driven Agents engineering team. The Agents team consists of AI/ML, backend, and full-stack engineers who collaborate to build delightful agentic experiences within our Comet ecosystem and Perplexity Computer, our platform for generalized frontier intelligence.
What you'll do
As an engineer on our Agents team, you will bring AI expertise, sharp product intuition, and a tinkerer's mindset to advance the frontier of what agents can accomplish for our millions of devoted users. 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.
What you need
-
Strong foundational familiarity with the full AI product stack;
-
Proficiency in Python (bonus points for TypeScript, Go, and/or Rust);
-
Significant experience in at least one of the following areas:
-
Context engineering and tool interfaces for frontier AI models
-
Post-training and reinforcement learning (particularly for multimodal models)
-
Browser technologies (CDP, Playwright, extension development, etc.)
-
