Member of Technical Staff (TPM, Inference)

Job summary

Responsibilities

Perplexity's mission is to power curiosity. Curious people are the people who drive change in the world. Driving change is a continuous cycle of learning, building, and integrating.

• Execute the roadmap for the inference platform request handling, rate limits and quotas, usage controls, and the reliability and observability surface engineering and product…
• Be the connective tissue between model providers and Perplexity's engineering and product teams coordinating onboarding, launch readiness, and rollout for new models and capacity
• Drive latency, throughput, uptime, and cost-efficiency as core execution metrics, surfacing tradeoffs between them rather than letting them become side effects
• Run the operating model for model-release and optimization programs, including day-zero launches, across performance engineering, infrastructure, and product teams
• Lead cross-functional delivery for inference-stack changes, from planning through launch and post-launch validation

What they're looking for

• Strong experience with technical program management or product management in infrastructure, distributed systems, or ML/model-serving products
• Direct experience with production LLM or ML inference understanding what makes serving fast, reliable, and cheap rather than just what a roadmap slide says about it
• Comfort orchestrating across external partners and internal engineering teams with competing priorities and timelines
• Experience with data and metrics, and the judgment to surface difficult tradeoffs between latency, throughput, uptime, and cost
• Thrives in a small, agile team; has initiative and desire for ownership without much precedent to lean on
