About the Team

OpenAI’s User Operations team shepherds our customers’ adoption of AI and ensures that our customers' product experience is nothing short of exceptional. We are building the very first post-AGI support team. We resolve complex issues, provide technical guidance, and support customers in maximizing value and adoption from deploying our products. We work closely with Sales, Technical Success, Product, Engineering and others, to deliver the best possible experience to our customers at scale.

About the Role

We’re looking for dedicated, experienced, and deeply curious individuals to help solve some of the most complex challenges faced by our customers while building the future of post-AGI support alongside us. In this role, you’ll work directly with customers through support tickets and live calls, troubleshooting high-impact issues and resolving novel, often ambiguous technical problems in one of the fastest-moving environments in technology.

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

How n8n and Automation Open Doors to Premium Jobs

The Paradigm Shift in Web Development

The web development market has matured. A few years ago, mastering a traditional stack (like MERN or LAMP) was enough to secure a highly sought-after role. Today, the corporate landscape — especially in US startups hiring globally and offering six-figure compensation — demands speed and operational efficiency. It's no longer just about building from scratch, but knowing how to integrate complex ecosystems rapidly.

According to Gartner, hyperautomation is one of the top strategic technology trends of the decade. The modern developer must be an integration architect, capable of connecting CRMs, databases, AI APIs, and payment gateways in a matter of hours, not weeks. This is exactly where n8n becomes an indispensable tool in your portfolio.

Why n8n? The Power of "Fair-Code"

n8n is a node-based workflow automation tool. Unlike competitors aimed at non-technical users (such as Zapier or Make), n8n was designed with the developer in mind first. It allows raw JavaScript injection for complex data manipulation, custom HTTP requests, and, most importantly, features a fair-code licensing model that allows it to be self-hosted on a company's own infrastructure.

For technical recruiters and CTOs, a candidate who masters n8n demonstrates maturity. It proves that you understand SaaS cost reduction and value the security and sovereignty of the company's data.

Practical Tips to Land Your Next Role

If you want your resume to pass rigorous ATS (Applicant Tracking System) screening — like Greenhouse or Ashby — and reach the hands of Tech Leads, here are the core skills you should highlight when associating Web Development with n8n:

  • Mastery of Webhooks and RESTful APIs: The foundation of automation is system communication. Demonstrate your ability to create n8n workflows that listen to native Webhooks from your application (e.g., a checkout event in a Next.js e-commerce app) and trigger subsequent actions with low latency.
  • Hosting and Docker: n8n's biggest differentiator is self-hosting. In your resume, mention your ability to package and orchestrate n8n instances using Docker and Docker Compose. Familiarity with Cloud providers (AWS, GCP, or DigitalOcean) to deploy these instances is a massive bonus.
  • Advanced JSON and JavaScript Manipulation: Show that you don't rely solely on pre-built integrations. Using the "Code" node in n8n to transform large JSON payloads using raw JavaScript or TypeScript is what separates a regular user from an automation engineer.
  • Error Handling and Resilience: Systems fail. APIs go down. An amateur automation will break a company's process. In your portfolio, document how you use Error Trigger nodes to build automated retries and send alerts to Slack/Discord when an integration fails.

Your Portfolio is the Ultimate Proof

Just listing "n8n" in the skills section of your resume isn't enough. Create a repository on GitHub containing a real-world use case. For example: export the JSON file of an n8n workflow that reads new leads from a PostgreSQL database, enriches the data using the OpenAI API, and sends them to a CRM. Add a detailed README.md explaining the architecture. This is the ultimate bait for Senior roles.
