About the Team

OpenAI’s Applied AI Engineering team helps organizations turn frontier AI capabilities into safe, reliable, and high-impact production systems. For software engineering organizations, this means helping customers adopt Codex and other OpenAI capabilities across the software development lifecycle—transforming how teams plan, build, test, review, and deliver software.

We work directly with engineering leaders and hands-on developers to identify high-value opportunities, design and implement AI-powered development workflows, and scale what works across engineering organizations. We turn lessons from these deployments into better products, reusable architectures, and technical patterns that help developers everywhere get more value from Codex.

About the Role

As an Applied AI Engineer focused on Codex, you will partner directly with leading engineering organizations to design, build, and deploy AI systems that transform how software is developed. You will combine deep technical judgment, hands-on engineering, and customer leadership to take ambitious ideas from workflow and use-case selection through prototyping, evaluation, production rollout, and scaled adoption.

You will work alongside engineering teams to build advanced AI coding workflows, integrations, automations, and evaluation systems—often using Codex itself as part of your development process. You will help customers make technical decisions involving model behavior, agentic workflows, developer environments, security, reliability, evaluation, and operational readiness, while ensuring deployments translate into measurable improvements in engineering productivity and software delivery.

You will work closely with OpenAI Product, Research, Engineering, Security, Sales, and the broader Codex organization, translating real-world deployment experience into high-signal product and model feedback. Success is measured by production systems, sustained developer adoption, and meaningful improvements to how engineering organizations build software—not simply successful demonstrations or enablement activity.

This role is based in our London office. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

  • Partner directly with engineering leaders and hands-on developers to identify high-value opportunities for Codex and translate them into technical architectures, implementation plans, evaluation strategies, and measurable success criteria.

  • Design, build, and deploy AI-powered software development workflows that improve how engineering teams plan, write, test, review, debug, and deliver software.

  • Work hands-on in code to build prototypes, evaluation harnesses, reference implementations, integrations, workflow automations, and production accelerators—often using Codex as part of your own development process.

  • Help customers progress from promising experiments to reliable production workflows, sustained developer adoption, and scaled impact across engineering organizations.

  • Design systematic approaches for evaluating AI coding systems using representative software engineering tasks, automated graders, production signals, and developer feedback.

  • Make sound technical decisions across models, agents, tools, developer environments, integrations, reliability, observability, latency, cost, safety, security, and operational readiness.

  • Diagnose complex implementation challenges, reproduce failures, test hypotheses, and drive technical blockers toward resolution.

  • Lead technical deep dives, workshops, and hands-on enablement that help engineering teams understand and adopt advanced AI coding workflows effectively and safely.

  • Gather high-fidelity insights from real-world Codex deployments and translate them into clear product proposals, model feedback, and technical requirements for OpenAI Product, Research, and Engineering teams.

  • Create reusable architectures, tooling, examples, guides, and technical patterns—including contributions to resources such as the OpenAI Cookbook—that accelerate future Codex deployments.

  • Influence customer engineering strategy by helping technical leaders understand how AI coding systems can reshape their software development lifecycle, engineering practices, and organizational workflows.

You’ll thrive in this role if you:

  • Have a demonstrated track record of designing, building, and delivering software or AI systems in enterprise environments, including taking systems from prototype to production. Relevant backgrounds may include applied AI or ML engineering, forward-deployed engineering, software engineering, developer tooling, customer engineering, solutions architecture, or technical consulting.

  • Can point to substantial personal contributions in code, architecture, evaluation, debugging, integrations, or production engineering—not only program, enablement, or stakeholder management.

  • Are highly proficient in Python and comfortable working across modern software development environments; experience with JavaScript, TypeScript, or another relevant language is valuable.

  • Are an active user of AI coding tools and have developed a strong point of view on how AI can improve developer productivity and software engineering workflows.

  • Enjoy building high-signal prototypes, integrations, automations, and production solutions that demonstrate and deliver what AI coding systems can enable.

  • Understand how to evaluate AI coding systems systematically, including designing representative tasks, automated evaluations, production signals, and mechanisms for incorporating developer feedback.

  • Have navigated enterprise production requirements such as developer tooling integrations, reliability, observability, security, privacy, data governance, performance, and cost.

  • Can connect technical decisions to developer workflows, adoption, engineering productivity, and measurable business outcomes.

  • Communicate with clarity and credibility across hands-on engineers, engineering leaders, security teams, product leaders, and executives.

  • Are comfortable leading technical workshops and hands-on sessions that help engineering organizations adopt new development workflows and technologies.

  • Bring high agency, strong technical judgment, and end-to-end ownership in ambiguous and rapidly evolving environments.

  • Learn quickly, challenge assumptions constructively, and collaborate with humility; deep prior experience with OpenAI products is not required.

  • Are able to speak English and French fluently.

Tech & Remote Glossary

Stop getting lost in interviews and job descriptions

The job market, especially within tech and global companies, has developed its own dialect. Not understanding these acronyms can make you lose valuable opportunities or poorly negotiate your contract. To end this problem, we created the Definitive Glossary for the Remote Professional.

🏢 Work Models & Routine

Async (Asynchronous Work)
A communication model where responses don't need to be immediate. Instead of back-to-back meetings, the team relies on well-structured documents, threads, and messages. It's the gold standard for global companies spanning multiple time zones.
Sync (Synchronous Work)
The opposite of Async. It requires the team to be online and available at the same time for meetings, live chats, and real-time collaboration.
Daily / Stand-up
A quick daily meeting (usually 15 minutes) common in Agile (Scrum) methodologies. The team answers three questions: What did I do yesterday? What will I do today? Are there any blockers?
All-Hands / Town Hall
A company-wide meeting involving all employees. Usually led by the founders (C-Levels) to present results, new goals, and answer team questions.
1:1 (One-on-One)
A recurring individual meeting between a professional and their direct manager. It is used for career alignment, feedback, and problem-solving, not just for project status updates.

💰 Contracts, Benefits & Compensation

PTO (Paid Time Off)
Instead of strict, categorized leave policies, modern US companies usually offer a flexible pool of days (e.g., 20 days of PTO, or even "Unlimited PTO") that you can use for vacations, sick days, or personal matters, while receiving your regular compensation.
Equity / Stock Options
Company ownership. The startup offers you the right to buy shares at a heavily discounted strike price in the future. If the company grows, goes public, or is acquired, these shares can be highly lucrative.
Vesting (Vesting Schedule)
The rule that controls your Equity. It usually lasts 4 years. You don't get all the shares on day one; you "earn" them gradually as you stay with the company. A "1-year Cliff" means you must stay for at least one year to receive your first batch of shares.
RSUs (Restricted Stock Units)
Unlike Stock Options (where you have the right to buy the stock), RSUs are actual shares the company grants you as a bonus or part of your compensation package, following a strict Vesting schedule.
Independent Contractor (1099 / B2B)
The most common international hiring model for global talent working for US companies. You act as a service provider (business-to-business), receiving the gross salary (often six-figure compensation) without standard local payroll tax deductions at the source.

🤖 Recruitment & Hiring Process

ATS (Applicant Tracking System)
The "robot" that reads your resume. Software like Greenhouse, Ashby, and Workday are used to filter candidates by keywords before a human even looks at the document. (Pro tip: this is why your resume must be clean, semantic, and have the right keywords).
JD (Job Description)
The document that lists the responsibilities, technical requirements, and benefits of the open position.
Cultural Fit
The interview stage that evaluates if your core values, communication style, and worldview align with the company's culture. This is the ultimate test of your Soft Skills.
Onboarding
The integration process. It's the period of your first few weeks at the company, where you get your access credentials, learn about the culture, study the internal documentation, and understand how the product works.

🚀 How to use this to your advantage?

The secret isn't just knowing what these acronyms mean, but using them actively. If during an interview for a premium tech role you ask, "How does your PTO policy and Vesting schedule work?", the recruiter will immediately perceive you as a high-level professional, familiar with the global market standards.

The remote job market requires preparation. And having the right vocabulary is the first big step to securing six-figure proposals and standing out among thousands of applicants.

Expert Tip

The Audiovisual Revolution in the Digital Age

Discover the skills, cloud tools, and strategic mindsets that tech giants, global agencies, and startups demand from video professionals in 2026.

The audiovisual market has undergone a radical transformation. The era when the best opportunities were restricted solely to traditional film studios or television networks is over. Today, the massive volume of premium hiring—including 100% remote positions and six-figure compensation packages—comes from tech companies, digital product startups, Growth Marketing agencies, and streaming-focused production houses.

To stand out in this new landscape, it is no longer enough to just "know how to cut video." The modern professional must be a visual problem solver, possessing a deep understanding of audience retention, cross-platform formats, and cloud-based workflows.

1. Master Cloud Workflows and Collaboration

If you are looking for a global remote position, the first barrier you will face is infrastructure. International production companies and tech startups no longer ship external hard drives via mail. They require candidates who know how to operate seamlessly within real-time review and collaboration ecosystems.

  • Frame.io: It has become the industry standard (now natively integrated into Adobe). Knowing how to manage real-time feedback and version control using Frame.io is an absolute prerequisite for senior editors.
  • Proxy Workflows: Mastering the creation and editing of proxies in Premiere Pro or DaVinci Resolve is non-negotiable for anyone editing 4K/6K footage remotely on standard internet connections.
"The ability to collaborate asynchronously and manage media in the cloud is no longer a perk, but the backbone of modern post-production teams." — Frame.io Insider

2. Embrace Integrated Artificial Intelligence

The fear of being replaced by AI is common, but corporate reality tells a different story: companies are actively hiring professionals who leverage AI to multiply their productivity. Tech recruiters are looking for talent who can automate tedious tasks and focus on high-level art direction.

  • Generative AI: Tools like Runway Gen-2, Midjourney, and Adobe Firefly are being used to create storyboards, expand backgrounds (Generative Fill), and generate auxiliary assets for Motion Graphics on the fly.
  • Audio and Roto AI: Using tools like Adobe Podcast AI for one-click audio cleanup and DaVinci Resolve's Magic Mask for automatic rotoscoping reduces hours of manual labor to mere minutes. Highlight these efficiency gains on your resume.

3. Your Portfolio is Your Ultimate Currency

In the audiovisual universe, your text-based resume matters far less than your Showreel. However, the most common mistake is creating a Reel filled only with pretty pictures and upbeat music, devoid of context.

According to hiring guidelines from top agencies listed on Motionographer, a top-tier portfolio must feature:

  1. The "Breakdown": Don't just show the final render. Show the layers, the color correction (before/after), or the raw shapes in After Effects. Prove that you are the architect behind the work.
  2. Focus on Results: If a video you edited for a TikTok Ads campaign increased conversion rates by 30%, state that clearly in the project description. Data-driven results secure B2B contracts.
  3. The Right Platforms: Forget Google Drive links. Host your work on Vimeo (for high-quality playback without ads) or Behance (for detailed project case studies). Even better: have your own dedicated website.

4. Soft Skills and B2B Dynamics

Video editors and motion designers often work in silos, but in modern tech companies, they are fully immersed in agile methodologies (Scrum/Kanban). You will need to interact daily with Copywriters, Product Managers, and Growth Analysts.

Knowing how to receive critical feedback without taking it personally, understanding the difference between a "technical revision" and a "strategic revision," and communicating rendering deadlines clearly are the soft skills that guarantee your retention in high-paying remote roles.
