Perplexity; San Francisco, Northern (CA, KY); Hybrid; USD 180,000 - 240,000; Full time

Job summary

Perplexity is seeking an Infrastructure engineer to own cross-cutting infrastructure problems spanning compute, storage, networking, data, deployment, and reliability, and to design, build, and operate distributed infrastructure across consumer, AI, and enterprise workloads.

You will lead complex programs, establish durable technical standards, and collaborate with partners in security, product, and AI to improve performance, availability, and cost-efficiency.

Qualifications

• 4+ years of professional software engineering experience building and operating production backend, platform, or distributed systems.
• Owns complex production systems end to end and delivers sustained technical impact across teams.
• Able to set technical direction, lead through influence, and raise the engineering bar through architecture, design reviews, and mentorship.
• Strong software engineering skills in Python or other backend languages such as Go, Rust, C++, or Java.
• Meaningful experience across at least two infrastructure domains, such as cloud platforms, distributed systems, Kubernetes, storage, databases, networking, data systems, developer infrastructure, or production reliability.
• Ability to develop depth quickly in unfamiliar systems, reason across software and infrastructure layers, and drive production incidents from diagnosis through durable resolution.

Responsibilities

• Own cross-cutting infrastructure problems that span compute, storage, networking, data, deployment, and reliability, including eliminating bottlenecks across retrieval and serving paths, building shared abstractions across deployment environments, and resolving failure modes that cross platform boundaries.
• Design, build, and operate distributed infrastructure supporting Perplexity’s consumer, AI, and enterprise workloads, owning systems from architecture through production operation.
• Identify gaps between existing platforms and build shared abstractions, automation, and tooling that make infrastructure easier and safer to use.
• Improve system performance, availability, scalability, and cost-efficiency across online request traffic and background workloads.
• Debug complex production issues across service and infrastructure boundaries, then turn the findings into durable architectural improvements.
• Set technical direction for complex infrastructure systems, lead high-impact programs across teams, and establish durable technical standards through collaboration with infrastructure, product, AI, and security partners.
