Frontend Developer

OpenAI

<div>
 
 About The Team
 
 
 
 The Codex App team builds and maintains the Codex desktop app and IDE extension &mdash; the primary ways developers interact with Codex. Our goal is to make AI feel like a real software engineering teammate inside real workflows: editing code, running tasks, reviewing changes, and coordinating long-running work.
 
 
 We sit at the intersection of research, product, and design. We ship quickly, learn from real usage, and continuously refine both the experience and the harness that connects users to the model.
 
 
 
 About The Role
 
 
 
 We&rsquo;re hiring a Frontend Software Engineer to build a top-tier desktop experience and push forward the interface for working with agents. This is a craft-heavy role: you&rsquo;ll partner closely with design to prototype, iterate, and polish new interaction models &mdash; then turn them into reliable, high-performance product.
 
 
 You&rsquo;ll help define what great looks like for &ldquo;human &harr; agent&rdquo; collaboration: what belongs in the UI, how state is represented, how progress and uncertainty are communicated, and how users stay oriented across long-running and multi-step work.
 
 
 
 What You&rsquo;ll Do
 
 
 
 <ul>
 <li>
 Build and ship polished, high-performance UI across the Codex desktop app and IDE extension.
 </li>
 <li>
 Partner tightly with design to turn prototypes into production-quality experiences (layout, motion, typography, interaction details).
 </li>
 <li>
 Iterate on future interfaces for interacting with agents: delegation, task timelines, status/progress, handoffs, review, and control surfaces.
 </li>
 <li>
 Own frontend architecture decisions (component systems, state management, navigation, rendering performance).
 </li>
 <li>
 Improve quality and reliability through testing, instrumentation, and thoughtful UX for failure modes.
 </li>
 <li>
 Collaborate with platform/model/backend partners to integrate new capabilities into cohesive product flows.
 
 
 </li>
 </ul>
 
 You Might Thrive Here If You
 
 
 
 <ul>
 <li>
 Have strong experience with modern frontend stacks (React, TypeScript) and a high bar for UI craft.
 </li>
 <li>
 Love design engineering: sweating the details while keeping velocity.
 </li>
 <li>
 Have built desktop-caliber product experiences (Electron or similar), and care about performance, responsiveness, and &ldquo;it just feels right.&rdquo;
 </li>
 <li>
 Enjoy exploring ambiguous problems and iterating rapidly with design and product.
 </li>
 <li>
 Think in end-to-end workflows, not isolated screens.
 </li>
 <li>
 Have experience with developer tools or IDE extensions (nice-to-have).
 
 
 </li>
 </ul>

 About The Team
 
 
 
 OpenAI&rsquo;s mission is to ensure AGI benefits all of humanity. The API organization is one of the highest-leverage ways we do that: we put frontier intelligence in the hands of builders who turn it into products, businesses, and services that reach people everywhere.
 
 
 We build the infrastructure and developer platform that makes that possible&mdash;so developers can reliably bring powerful AI into the real world, operate it safely at scale, and keep pushing what&rsquo;s possible. When we do our job well, we don&rsquo;t just ship an API. We enable thousands of teams to create new capabilities for millions of end users, accelerating progress across industries and communities.
 
 
 
 About The Role
 
 
 
 As a Data Scientist on the API team, you&rsquo;ll build the measurement systems that make our platform legible and improveable. You&rsquo;ll define the metrics that matter, identify and quantify developer friction, evaluate launches and platform changes, and translate data into product decisions that improve reliability and developer outcomes at scale.
 
 
 You&rsquo;ll partner closely with Product, Engineering, Research, and Finance to ensure our metrics are trusted, our experimentation is rigorous, and our insights turn into shipped improvements.
 
 
 This role is based in San Francisco. We use a hybrid work model of three days in the office per week and offer relocation assistance to new employees.
 
 
 
 In This Role, You Will
 
 
 
 <ul>
 <li>
 Own the core KPI framework for the API platform, spanning developer adoption, engagement, retention, and platform health.
 </li>
 <li>
 Build end-to-end funnels that identify where developers succeed or get stuck&mdash;from first integration through scaling to production.
 </li>
 <li>
 Define and operationalize platform guardrails (e.g., reliability, latency, error rates, cost/efficiency) and connect them to user outcomes.
 </li>
 <li>
 Design and evaluate experiments and rollouts to quantify the impact of platform and product changes.
 </li>
 <li>
 Partner with product and engineering teams to improve instrumentation, data quality, and metric definitions so decisions are fast and correct.
 </li>
 <li>
 Translate complex analysis into clear, actionable insights for leadership and cross-functional stakeholders.
 </li>
 <li>
 Develop and socialize dashboards, tools, and self-serve data products that help teams answer product questions quickly.
 </li>
 <li>
 Help establish data science standards and best practices for measuring AI platform performance and developer success.
 </li>
 <li>
 Partner with other data scientists across the company to share learnings and raise the bar on measurement and decision-making.
 
 
 </li>
 </ul>
 
 You Might Thrive In This Role If You Have
 
 
 
 <ul>
 <li>
 10+ years of experience in data science roles within product or technology organizations (platform or developer-facing experience is a plus).
 </li>
 <li>
 Expertise in statistics and causal inference, applied in both experimentation and observational studies.
 </li>
 <li>
 Expert-level SQL and proficiency in Python for analytics, modeling, and experimentation.
 </li>
 <li>
 Proven experience designing and interpreting experiments and making statistically sound recommendations.
 </li>
 <li>
 Experience building datasets, metrics, and data pipelines that power production decision-making.
 </li>
 <li>
 Experience developing and extracting insights from business intelligence tools (e.g., Tableau) and building self-serve solutions.
 </li>
 <li>
 Strong product sense and an impact-driven mindset: you turn ambiguity into crisp frameworks that drive roadmap decisions.
 </li>
 <li>
 Ability to build relationships with diverse stakeholders and cultivate strong partnerships across Product, Engineering, Research, and GTM teams.
 </li>
 <li>
 Strong communication skills, including the ability to bridge technical and non-technical audiences.
 </li>
 <li>
 Ability to operate effectively in a fast-moving, ambiguous environment with limited structure.
 </li>
 <li>
 Are consistently among the first to adopt the latest AI tools, you use them daily to increase your own throughput, and you proactively turn them into durable workflows that change how your team and org operate.
 
 
 </li>
 </ul>
 
 Nice-to-haves
 
 
 
 <ul>
 <li>
 Experience with developer platforms, APIs/SDKs, or usage-based products.
 </li>
 <li>
 Experience with platform reliability analytics, incident impact measurement, or performance/cost optimization.
 </li>
 <li>
 Familiarity with AI evaluation and quality measurement systems (online/offline evals, human-in-the-loop, safety/quality guardrails).
 
 
 </li>
 </ul>
 
 Why it matters
 
 
 
 When developers build on OpenAI, they put our platform into products that touch millions of people. API Data Science ensures we make the right bets, operate with rigor, and continuously raise reliability and usability as the platform scales. This is a unique opportunity to shape how frontier AI is measured, improved, and delivered through a platform that powers the next generation of AI products.
