Perplexity is looking for experienced Backend Engineers to build the foundational systems behind our core products. As we move toward agentic products that can reason, delegate, use tools, and execute complex workflows, backend engineering is one of the most important parts of making that experience reliable at scale. You’ll help design and operate the systems that connect models, data, product surfaces, and infrastructure into a platform millions of people and companies can depend on.
We’re hiring across several backend teams, and we’ll match you with a specific group after you complete the interview process, factoring in both your background and what you’re excited to work on. This lets us place engineers where their skills and interests line up with the highest-impact backend product work and the strongest opportunities for growth.
Teams Hiring
- Cloud Infrastructure: The Cloud Infrastructure team owns the foundational cloud primitives and deployment models that power Perplexity's products, from multi-tenant public cloud to single-tenant and on-premises solutions for enterprise customers. As Perplexity expands into Computer and Enterprise offerings, this team is critical to delivering the security, isolation, and compliance controls that enterprise companies require, while maintaining the reliability and efficiency engineers depend on across all environments. By architecting flexible deployment topologies, multi-region support, and robust low-level infrastructure, the Cloud Infrastructure team enables Perplexity to scale from millions of consumer users to the world's largest organizations with confidence.

This foundational, high-impact group is responsible for the full spectrum of storage technologies – relational databases, vector databases, custom storage implementations, and the tooling to provision, monitor, and optimize them at scale. By building robust abstractions and operational excellence around storage, the team enables engineers across Perplexity to focus on product innovation while trusting that data is fast, reliable, and always accessible.
- Backend Platform: The Backend Platform team is the backbone of Perplexity’s product reliability, scalability, and performance, enabling every product and AI team to build with confidence. This small, high-impact group builds and maintains critical infrastructure, including backend systems for authentication, authorization, real-time data flows, service orchestration, and sandboxing, to ensure fast, reliable, and secure user experiences. By setting rigorous standards for code quality, uptime, and developer productivity, the Platform team ensures everyone at Perplexity can innovate at speed on top of a robust, well-architected foundation.
