OpenAI's Applied AI Engineering (Codex) team is seeking a technically deep, creativity-driven Applied AI Engineer to help customers adopt OpenAI's coding tools throughout their software development lifecycle. You will act as a trusted technical partner, guiding engineering teams as they integrate Codex into their projects and workflows, working with customers ranging from digital-native companies to global enterprises.
In this role, you will serve as the primary technical subject matter expert on OpenAI Codex for a portfolio of customers, embedding deeply with them to enable their engineering teams and build coding workflows. You'll partner directly with customers to design and implement AI-enhanced development workflows, from rapid prototyping through scalable production rollout. You will build high-quality demos, reference implementations, and workflow automations, using Codex itself as part of your development process.
You'll lead large-format workshops, technical deep dives, and hands-on enablement sessions that help engineering organizations adopt AI coding tools effectively and safely. You'll contribute technical content including examples, guides, patterns, and best practices to the OpenAI Cookbook to help the broader developer community accelerate their work with Codex. You'll gather high-fidelity product insights from real customer deployments and translate them into clear product proposals and model feedback for internal teams.
This is a highly cross-functional role that blends technical architecture, product strategy, and customer-facing leadership. You'll work closely with Sales, Solutions Engineering, Product, Applied Engineering, and the broader Codex organization to advocate for customer needs, shape product direction, and accelerate the successful deployment of intelligent coding systems across some of the world's most influential companies. You'll influence customer strategy and decision-making by framing how AI coding tools fit into their SDLC, technical roadmap, and organizational workflows, and serve as a trusted advisor on solution architecture, operational readiness, model configuration, security considerations, and best-practice adoption.
The role is based in Singapore with a hybrid work model of 3 days in office per week. Relocation assistance is offered to new employees.
REQUIREMENTS:
- Ability to speak Mandarin (required, as you will work with Mandarin-speaking customers and/or vendors)
- 5+ years of technical consulting, post-sales engineering, solutions architecture, or similar experience working directly with customers
- Active power user of AI coding tools with deeply customized developer workflow; demonstrated point of view on what makes engineers more productive
- Experience building scrappy, high-signal demos, integrations, and prototypes that clearly articulate what Codex can enable, often using Codex to accelerate your own development process
- Experience delivering large, high-impact workshops or technical training to engineering teams; ability to craft engaging, hands-on, outcomes-driven sessions
- Track record of contributing technical guides, patterns, or examples publicly with focus on clarity, pedagogy, and community impact
- Ability to communicate complex technical concepts in clear, persuasive written and verbal form, especially when helping customers make strategic decisions about AI application
- Comfort with ambiguous, rapidly evolving problem spaces; ability to iterate toward novel solutions hand-in-hand with customers
- Strong commitment to customer success, reliability, safety, and operational excellence alongside technical ingenuity
