About the role
- As an Operating Systems Engineer focused on connectivity and networking, you will design, develop, and maintain the OS capabilities that enable reliable, secure, and efficient communication across OpenAI products and systems.
- Your work will span Wi-Fi and Bluetooth frameworks, IP networking, and advanced network services and policy.
- You'll develop OS services, libraries, and interfaces for a broad range of connectivity needs, make design decisions across software boundaries, and carry solutions through development, integration, and production.
Responsibilities
- Design, implement, and maintain OS services, frameworks, and APIs for Wi-Fi, Bluetooth, and IP networking.
- Build connection management, network configuration and selection, service discovery, and routing capabilities.
- Develop network services and policies for secure communication, traffic management, and isolation across varied network environments.
- Investigate correctness, concurrency, interoperability, and reliability issues across OS components, protocol stacks, and application interfaces.
- Use tracing, profiling, and repeatable measurements to improve latency, throughput, resource use, and power efficiency.
- Build diagnostic tools, representative workloads, and automated tests to validate interoperability and failure recovery across changing network and operating conditions.
- Partner with hardware, firmware, security, platform, and application engineers to translate system requirements into shipped capabilities and clear, maintainable interfaces.
Requirements
- Substantial hands-on experience developing Wi-Fi and Bluetooth functionality in operating-system frameworks, system services, or connectivity middleware.
- Strong understanding of IP networking, including IPv4/IPv6, TCP/UDP, DNS, DHCP, routing, and socket behavior, with practical experience implementing and debugging networked systems.
- Experience implementing advanced networking capabilities in one or more areas such as routing and network policy, VPNs and tunneling, traffic management, or network isolation.
- Experience designing and maintaining platform APIs and the services behind them, including connection lifecycle management and integration with other OS components.
- Proficiency in C++ for systems development, including concurrent programming, memory ownership, and resource lifetime management.
- Strong understanding of asynchronous systems, interprocess communication, and failure handling.
- Experience diagnosing complex connectivity issues using system traces, protocol captures, logs, and structured debugging.
- Ability to work across disciplines, make sound technical tradeoffs, and carry solutions from investigation through implementation and validation.
