Perplexity

Build user-facing AI products end to end as an early-career full-stack engineer, shipping quickly across frontend, backend, data, and search or model integrations. You’ll turn ambiguous ideas into production experiences used at significant scale.

Build foundational search-engine infrastructure at Perplexity, focusing on indexing pipelines, data processing, storage formats, and retrieval systems operating at the scale of billions of pages. This systems-focused role combines low-level performance optimization with distributed, high-load production engineering.

Join Perplexity’s Agents engineering team to build AI agents that navigate digital environments, use tools, and accomplish valuable work for users. This role combines AI engineering, applied research, product development, and agent reliability across desktop, mobile, and cloud environments.

Build the next generation of agent capabilities that turn frontier AI model advances into reliable, scalable product experiences. This high-ownership role spans agent systems, applied AI, backend services, evaluation, and user-facing product innovation.

Join Perplexity’s Infrastructure team to build and operate distributed systems powering real-time search, retrieval, model serving, and agent workloads. This cross-cutting role combines hands-on infrastructure engineering with technical direction across platform boundaries.

Join a full-time, in-person Berlin internship focused on advancing search quality through deep learning, retrieval, ranking, and representation-learning research. You will train large-scale models and build optimized RAG pipelines for search and answer generation.

Build and scale the distributed backend systems powering Perplexity’s realtime voice and multimodal AI experiences. You’ll own session infrastructure, streaming protocols, orchestration, and new products from design through launch.

Forward Deployed Engineers embed with strategic customers to scope, build, deploy, and harden AI-powered enterprise workflows using Perplexity Computer. This hands-on role combines engineering, solutions architecture, and technical program management to deliver measurable customer outcomes.
