首席软件工程师，基础设施安全
Principal Software Engineer, Infrastructure Security
关于团队
安全是OpenAI使命的基石，旨在确保人工通用智能造福全人类。
安全团队保护OpenAI的技术、人员和产品。我们在构建时是技术性的，但在执行时是运营性的，并支持OpenAI的每一个产品和研究项目。我们的原则包括优先考虑影响力，赋能研究人员和开发者，为未来变革性技术做好准备，并培养强大、协作的安全文化。
关于职位
OpenAI正在寻找一位高级软件工程师加入基础设施安全（InfraSec）团队。InfraSec保护OpenAI研究和生产环境的核心部分：GPU超级计算集群、多云基础设施、数据中心、网络、存储以及支撑我们前沿AI模型的关键服务。我们的职责范围涵盖从裸机硬件和固件到Kubernetes集群、服务网格，以及承载高度敏感模型权重和用户数据的数据路径。
作为高级软件工程师，您将设定关键基础服务的技术方向并推动其执行，例如身份验证系统、出站/入站代理、访问代理和密钥管理平台，这些服务需要高标准的可靠性、可扩展性和软件工程工艺。这些系统构成了OpenAI客户和超级计算环境的安全核心，必须在高强度规模和对抗压力下保持稳健。
在此职位中，您将：
- 负责一个或多个核心安全服务（例如身份验证/授权、策略执行、安全代理、密钥管理）的架构和路线图，从设计到部署再到长期运维。
- 设计和实现覆盖硬件、操作系统、Kubernetes、网络和CI/CD的全球规模安全系统：在安全性、可靠性、延迟和开发者易用性之间取得平衡。
- 领导与基础设施和研究工程团队的跨职能发布，塑造接口、迁移计划和在大规模车队和关键工作流中的安全发布策略。
- 构建或演进安全原语（身份、认证、授权、加密密钥生命周期、访问中介），成为OpenAI平台的构建模块。
- 利用前沿模型和代理开发自动化和检测工具，持续识别和缓解大规模环境中的风险。

About the Team
Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.
The Security team protects OpenAI’s technology, people, and products. We are technical in what we build but operational in how we execute, and we support every product and research effort at OpenAI. Our tenets include prioritizing for impact, enabling researchers and developers, preparing for future transformative technologies, and fostering a strong, collaborative security culture.
About the Role
OpenAI is seeking a Principal Software Engineer to join the Infrastructure Security (InfraSec) team. InfraSec safeguards the core of OpenAI’s research and production environments: GPU supercomputing clusters, multi-cloud infrastructure, datacenters, networking, storage, and the critical services that power our frontier AI models. Our charter spans everything from bare-metal hardware and firmware to Kubernetes clusters, service meshes, and the data pathways that carry highly sensitive model weights and user data.
As a Principal Software Engineer, you will set technical direction and drive execution of critical foundational services, such as authentication systems, egress/ingress proxies, access brokers, and key management platforms, that demand high standards of reliability, scalability, and software craftsmanship. These systems form the security backbone of OpenAI’s customer and supercomputing environment and must remain robust under intense scale and adversarial pressure.
In this role, you will:
- Own the architecture and roadmap for one or more core security services (e.g., authN/Z, policy enforcement, secure proxies, key management), taking them from design to rollout to long-term operation.
- Design and implement planet-scale security systems that provide strong guarantees across hardware, operating systems, Kubernetes, networks, and CI/CD: balancing security, reliability, latency, and developer ergonomics.
- Lead cross-functional launches with infrastructure and research engineering teams, shaping interfaces, migration plans, and safe rollout strategies across large fleets and critical workflows.
- Build or evolve security primitives (identity, attestation, authorization, encryption key lifecycle, access mediation) that become platform building blocks for OpenAI.
- Leverage frontier models and agents to develop automation and detection tooling to continuously identify and mitigate risks in large-scale cloud and on-prem environments.
- Lead design reviews and threat models for major initiatives, and drive closure on systemic issues.
- Mentor engineers across InfraSec and partner teams, raising the bar on engineering quality, operational readiness, and secure-by-default practices.
You will thrive in this role if you have:
- Strong software engineering skills with a track record of shipping and operating reliable distributed systems in production.
- Experience building or operating critical infrastructure, especially security infrastructure, at planet scale (e.g., auth services, service-to-service proxies, certificate or key-management systems).
- Deep understanding of security principles, best practices, and common vulnerabilities.
- Demonstrated ability to lead cross-team technical initiatives: setting direction, aligning stakeholders, driving execution, and delivering measurable outcomes.
- Expertise and curiosity about using frontier models and agents to effectively solve security challenges.
- Expertise in securing large-scale cloud platforms (e.g., Azure, AWS, GCP), including multi-cloud networks and cloud-agnostic system design.
- A proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
- Strong analytical and problem-solving skills, with an ability to think critically and objectively assess risks.
- Excellent communication skills, with the ability to convey complex security concepts to executive, technical, and non-technical stakeholders.
