Teams Currently Hiring

File Platform

The File Platform team builds and owns the unified, scalable, and secure file layer that powers attachments, syncing file drives, and generated file assets across all Perplexity products. They provide end‑to‑end capabilities for parsing, indexing, content moderation, connectors to cloud/local storage, file search APIs/tools, and user file management. This team defines clear platform abstractions and a generic extensible API, and is responsible for high quality, performance, reliability, and cost efficiency as the single source of truth for all file-related functionality at Perplexity.

Enterprise Growth

The Enterprise Growth team builds the core platform capabilities that make Perplexity a secure, reliable, and adoption-driving product for enterprise customers, owning end-to-end experiences across enterprise authentication (SSO, SCIM, RBAC), org creation and onboarding (white-glove and self-serve flows, invitations, discovery of existing orgs), and admin control and visibility (feature/model/connector controls, Comet controls, audit logs, usage analytics, and growth-related upsell surfaces) to ensure enterprises can confidently deploy Perplexity at scale and realize measurable business impact.

Connectors

The Connectors team builds the platform that links Perplexity to users’ external apps and data sources (e.g. MCP servers and API providers such as Gmail, Slack, Notion, and more), enabling secure auth, fast and reliable tool calls, automatic connector selection based on the user’s query, and rich, correctly cited answer rendering, while also powering Spaces/Agents that orchestrate multi-step workflows over those connectors for true end‑to‑end automation across Perplexity’s products.

Growth

The Growth team shapes how millions of people experience Perplexity. We rapidly experiment and launch new ideas across all user-facing surfaces at Perplexity including onboarding, verticals like Students, and premium Max Tier. We build AI-powered features such as personalized prompts, auto-generated study guides, and contextual upsell nudges, driving user activation, retention, and revenue across all platforms. We own Perplexity’s growth platform, including experimentation framework, feature flagging, and notifications, to mobilize impactful feature development across the company. Engineers have outsized impact, building both the product and the platform that power our company’s growth.

Commerce

The Commerce team owns the full commerce stack: payments infrastructure, agentic commerce capabilities, and emerging monetization opportunities as we explore what's possible. The team builds and scales billing infrastructure across consumer subscriptions, enterprise plans, API usage (Sonar), and premium features. We also develop and maintain secure, scalable systems—including agentic payments that autonomously interact with payment platforms—ensuring reliable financial transactions for millions of users worldwide. By shaping both user experience and revenue infrastructure, the Commerce team sits at the core of Perplexity’s growth and sustainability.

Core Experience

The Core Experience team designs and builds the refined human‑machine interface at the heart of Perplexity: the core asking experience across web, mobile, and Comet. We own the cross-platform foundations that make querying feel effortless—expressive UX patterns, tight frontend interactions, and clear information hierarchy—while maintaining the clean abstractions and performant APIs that client platform teams rely on. This team is engineering-led and highly technical, working closely with platform owners to solve hard cross-cutting problems and uphold uncompromising standards for design, architecture, and craft. We obsess over core quality—latency, reliability, and extensibility—so Perplexity stays fast, consistent, and scalable as LLMs and agents evolve.

Live Events

With AI-powered exploration and browsing, personalization and memory, live data visualization, comparison, and checkout, Perplexity is reimagining the consumer experience across verticals such as travel, shopping, health, real estate, finance, sports, live events and ticketing, and more. Each of these verticals represents an opportunity for Perplexity to disrupt massive markets dominated by slower-moving incumbents. Agentic actions powered by Comet unlock novel consumer experiences such as automated shopping and travel purchases, restaurant reservations, complete travel itineraries planned and booked from scratch, automated investing and financial analysis, and more.
