Software Engineer, Productivity - Networking

OpenAI’s networking teams design and manage high-performance systems that support the company’s training and inference infrastructure. As a Software Engineer focused on productivity, this position centers on making those teams more effective by improving the developer experience and streamlining complex workflows. Role overview This role supports engineers working on intricate infrastructure, with a focus on build systems, testing architecture, release pipelines, and overall development efficiency. The work involves optimizing how engineers build, test, validate, and deploy changes in environments that span multiple servers and interact closely with hardware. What you will do Improve development workflows for engineers building and operating networking systems at OpenAI. Design and refine pipelines for continuous deployment, release, and validation. Create and maintain test harnesses for multi-server, networked, and hardware-backed environments. Increase iteration speed across codebases, particularly in C++, Python, and environments centered on build systems. Work with engineers to identify and resolve pain points in CI, testing, debugging, and deployment processes. Lead testing and reliability strategies for infrastructure components that support large-scale training and inference workloads. Collaborate with both centralized developer experience teams and networking engineers who work directly with these systems.

Role overview Meter Inc. is developing tools to capture and preserve the expertise of network engineers. The team’s goal is to build systems that document how experts diagnose network issues, making it possible for future models to manage networks with less manual effort. This work will help Meter support many customer networks while reducing the need for direct engineer intervention. What makes this work unique Network engineering lacks the structured archives found in software development. While Git and GitHub record software decisions, the reasoning behind network troubleshooting often disappears once a problem is fixed. This role centers on building a structured, searchable system for network operations, a kind of GitHub for network engineering. The system will capture network state, expert observations, and the logic behind key decisions. Your first 90 days First 30 days: Meet with network engineers to learn their workflows. Study what effective diagnostic documentation looks like and identify the necessary data. Review telemetry (ClickHouse), configurations (Postgres), and support history (Salesforce). By 60 days: Deliver a working annotation interface. Network engineers should be able to review past support tickets, view the network’s state during incidents, and record their reasoning. The tool should be practical and encourage regular use. By 90 days: Network engineers will be able to create training data independently. Initial model benchmarks from your pipeline will be live, showing how your work improves the process. Technical stack TypeScript React Go GraphQL Kafka Postgres Collaboration This role works closely with Meter’s co-founder and CEO, who will help guide the product roadmap and set priorities. Location This position is based in San Francisco.

Join us at sfcompute as we revolutionize the landscape of infrastructure development, addressing the complexities of the largest infrastructure build-out ever undertaken.In the realm of GPU financing, where massive data centers and their supporting infrastructure are involved, the concept of 'offtake' is crucial—this means securing lease contracts before the clusters are even constructed.The risk associated with financing GPU clusters is significant, given the slim margins and vast volumes involved. Lenders seek assurance that developers can meet their financial obligations, while developers are keen to avoid the pitfalls of unsold clusters. Consequently, this risk is often transferred to customers through fixed-price long-term contracts.Without effective risk mitigation for customers, the industry faces potential collapse. Unlike traditional SaaS models, application companies are tied into long-term contracts for computational resources but operate under monthly billing to end-users. A small misstep in sales can lead to dire financial consequences. Imagine if companies had the option to exit their contracts by reselling them in a liquid market.As AI technology advances, access to compute power may increasingly be restricted to those who can shoulder substantial financial risks. A small startup in San Francisco shouldn't have to commit to a lengthy, high-value contract for supercomputers; instead, they might benefit from flexible liquidity options provided by the market.This is precisely what we are creating: a vibrant, liquid market for GPU offtake.About the RoleAs a Product Software Engineer at sfcompute, you will play a pivotal role in developing products that mitigate risks associated with this monumental infrastructure buildout.Your work will involve collaborating across teams to design and implement sophisticated yet user-friendly interfaces for:Public cloud services that provide access to billion-dollar supercomputers.Innovative computing markets and their associated financial products.Cost-effective trillion-token inference capabilities.ResponsibilitiesLead the development of new user-facing features for our public cloud platform, marketplace, and other products.Deliver outstanding user experiences through meticulous UI/UX design, utilizing frameworks like React and Next.js.Collaborate with developers from leading AI startups and research labs to transition features from concept to production, directly addressing their demands.... (additional responsibilities to be detailed).
