技术成员（通用软件工程师，基础设施）
Member of Technical Staff (General Software Engineer, Infrastructure)
关于该职位
基础设施团队构建并运营支撑Perplexity产品基础系统。在Perplexity，基础设施是每个答案的关键路径，支持实时搜索、检索、模型服务和代理工作负载，其中延迟、可靠性和快速迭代直接影响用户体验。该职位面向具备多领域经验的基础设施工程师，他们热衷于解决跨平台的复杂问题，这些问题往往无法简单地归入单一平台团队。
你不需要在每个领域都是专家。职责范围从负责主要生产系统到为多个团队设定技术方向，领导复杂的基础设施项目，并塑造整个组织的基础设施战略。如果你的专业领域是云基础设施、存储平台、后端平台、数据平台、连接器平台或AI加速，且这些职位与你的技能和兴趣高度匹配，请直接申请相应职位。如果你的经验涵盖多个基础设施领域，或者你最热衷于解决跨系统的复杂问题，请申请此职位。提交一份申请，我们将考虑你在整个基础设施团队中的机会。
关键职责
- 负责跨领域的基础设施问题，涉及计算、存储、网络、数据、部署和可靠性，包括消除检索和服务路径中的瓶颈，构建跨部署环境的共享抽象，解决跨平台边界的故障模式。
- 设计、构建和运维支持Perplexity消费者、AI和企业工作负载的分布式基础设施，从架构到生产运维全程负责系统。
- 识别现有平台之间的差距，构建共享抽象、自动化和工具，使基础设施更易于使用且更安全。
- 提升在线请求流量和后台工作负载的系统性能、可用性、可扩展性和成本效率。
- 调试跨服务和基础设施边界的复杂生产问题，然后将发现转化为持久的架构改进。
- 为复杂的基础设施系统设定技术方向，领导跨团队的高影响力项目，并通过与基础设施、产品、AI和安全合作伙伴的协作建立持久的技术标准。
任职要求
- 4年以上专业软件工程经验，构建和运维生产系统

ABOUT THE ROLE
The Infrastructure team builds and operates the foundational systems behind Perplexity’s products. At Perplexity, infrastructure sits on the critical path of every answer, supporting real-time search, retrieval, model serving, and agent workloads where latency, reliability, and rapid iteration directly shape the user experience. This role is for strong infrastructure engineers whose experience spans multiple domains and who are energized by cross-cutting problems that do not fit neatly within a single platform team.
You do not need to be a specialist in every area. Scope ranges from owning major production systems to setting technical direction across teams, leading complex infrastructure programs, and shaping infrastructure strategy across the organization. If a specialized Cloud Infrastructure, Storage Platform, Backend Platform, Data Platform, Connector Platform, or AI Acceleration role clearly matches your expertise and interests, apply directly to it. If your experience spans several infrastructure domains or you are most energized by cross-cutting systems problems, apply here. Submit one application, and we will consider you across the Infrastructure organization.
KEY 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.
QUALIFICATIONS
- 4+ years of professional software engineering experience building and operating production backend, platform, or distributed systems.
- A track record of owning complex production systems end to end and delivering sustained technical impact across teams.
- Demonstrated ability 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 systems or 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.
If you’re excited about this role, we encourage you to apply even if your experience doesn’t match every qualification listed above.
