## Role details

## About the Team

The Applied AI Engineering team works closely with frontier startups. We serve as trusted advisors and thought partners, ensuring that OpenAI’s technology is deployed safely and effectively. We also partner with engineering, research, and product teams to translate these insights into evaluation systems, product improvements, and better model behavior.

This team sits at the intersection of customer reality and model quality. We combine deep technical expertise with strong product judgment to translate complex, high-value use cases into clear signals that improve both the customer experience and the underlying systems.

## About the Role

As an Applied AI Engineer focused on Codex for startups, you will help developers and founders transform how they build and ship software. You will combine hands-on engineering, startup experience, and compelling technical communication to help teams turn the potential of AI coding tools into practical, effective workflows.

Presentations and community engagement are central to this role. You will engage developers and founders through technical talks, live demos, workshops, and various programs across the startup ecosystem, in addition to targeted work with individual customers. You will build reusable tools and resources to extend your impact and bring insights from developers back to OpenAI’s Product, Research, and Engineering teams.

This role is ideal for someone who enjoys both hands-on building and sharing what they learn. You should be as enthusiastic about leading a room of developers, delivering an engaging presentation, and building relationships in the startup community as you are about tackling a technical problem in code, with a focus on sustained adoption and meaningful improvements in how startups operate.

## Responsibilities

    
- Partner with top startups to identify key areas where Codex can most significantly impact how their teams build and ship software.
    
- Design and lead technical talks, live demos, workshops, hackathons, and repeatable hands-on programs designed to convert initial interest into sustained adoption.
    
- Work directly with selected customers to build Codex workflows, integrations, and automations, resolving technical blockers while evaluating effectiveness and reliability.
    
- Convert successful implementation approaches into reusable code examples, guides, and tools to help more startups succeed with Codex and OpenAI’s broader platform.
    
- Collaborate with account teams, developer experience, and ecosystem partners to reach developers and founders, prioritize opportunities, and drive measurable customer value.
    
- Translate customer experiences and developer feedback into actionable insights for OpenAI’s Product, Research, and Engineering teams.

## Qualifications

You will thrive in this role if you:

    
- Have experience building at, founding, or working closely with early-stage startups, demonstrating an understanding of the associated pace, ambiguity, and practical trade-offs.
    
- Possess strong software engineering fundamentals and enjoy building practical AI applications, integrations, and developer tools.
    
- Are an active user of Codex or other AI coding tools, possessing a thoughtful perspective on how these tools can advance software development.
    
- Are a compelling communicator who enjoys presenting, delivering live demos, and leading hands-on workshops for developers and founders.
    
- Have a talent for translating complex technical ideas into clear explanations, engaging examples, and reusable resources that help others succeed.
    
- Combine developer empathy with sound technical judgment: the ability to discover team needs, troubleshoot issues, and guide them toward adopting effective, reliable workflows.
    
- Exhibit high agency, curiosity, and end-to-end ownership, capable of working independently while collaborating closely with colleagues and ecosystem partners.
