Details
Perplexity is seeking energetic engineers to join its highly driven Agents engineering team. The team consists of backend, full-stack, and AI/ML engineers who collaborate to build harnesses and AI systems powering agentic experiences, including Perplexity Computer, the Comet ecosystem, the Agent API, and more.
The vision is to empower users with agents that can faithfully actualize their intent through open-ended interactions with the world. Engineers on the Agents team bring AI expertise, product intuition, and a tinker's mindset to advance what agents can accomplish.
The work spans applied research and engineering, including designing AI agents to navigate the digital world, training action and decision models based on complex multimodal states, supporting desktop, mobile, and headless cloud environments, developing permission architectures and payload classifiers, and designing data representations and interaction modes between agents and their environments.
Responsibilities
- Engineer agent harnesses that connect powerful models with the environments and tools required to perform economically valuable work for users.
- Drive cutting-edge AI capabilities across multiple layers of a rapidly growing AI agents product.
- Develop and leverage AI models, infrastructure, and browser technologies to advance the capability frontier and scale those capabilities for a rapidly growing user base.
- Ensure a high craft and quality bar for both AI agent performance and user experience.
- Collaborate with engineers, designers, product managers, data scientists, and others across the company to integrate core Perplexity functionality into frontier agentic products and vice versa.
- Contribute to product reliability, code quality, AI evaluation, testing, and maintenance across the broader team.
Requirements
- Strong foundational familiarity with the full AI product stack.
- Proficiency in Python; TypeScript, Go, and/or Rust are a bonus.
- 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, including CDP, Playwright, and extension development.
- Strong product intuition and a taste for user experience excellence.
- Comfort working with a small, fast-moving team, with a willingness to dive in and take ownership.
- Passion for shipping products that surprise and delight.
