Software Engineer, Implicit Signals

OpenAI; United States; Remote; USD 140,000 - 180,000; Full time

Job summary

OpenAI is seeking a software engineer to build and evolve our classification and evaluation platform. You’ll develop services, online and offline pipelines, and tools that help researchers turn an idea into a working measurement and iterate quickly.

This role blends software and data engineering with hands-on production ownership. You’ll shape the architecture, deliver new capabilities, improve inference efficiency, and keep the system dependable as workloads evolve.

Responsibilities

• Design and build software services and APIs for configuring, running, and managing classifiers and evaluations.
• Build and operate online and offline classification pipelines that support reliable, efficient execution at scale.
• Improve model‑serving performance, including throughput, latency, concurrency, and compute utilization.
• Build tools that make experimentation, debugging, and iteration straightforward for researchers and data scientists.
• Own production reliability, observability, and incident response, and reduce the operational burden of running the platform.
• Partner with machine learning engineers to bring new classification capabilities
