Remote AI Trainer (Finance/Coding/Medicine) Worldwide — Columbus
Traveler-Friendly Insight
This role is about as nomad-friendly as it gets. TrainBrain's AI Trainer position is fully async, location-independent, and self-scheduled — there are no fixed hours, no time zone requirements, and no client calls to coordinate. You pick your projects and set your own pace, making it ideal for anyone juggling travel with professional income.
At $45–$100/hr, even modest hours can generate strong income relative to popular nomad bases:
- Lisbon, Portugal: A comfortable monthly budget of ~$2,500–$3,000 means just 30–40 hours/month at mid-range rates covers living costs, leaving plenty of exploration time.
- Bangkok, Thailand: With a budget around $1,500–$2,000/month, 20–30 hours covers expenses comfortably — one of the best income-to-cost ratios available.
- Medellín, Colombia: At ~$1,800–$2,500/month, a light 25–40 hour workload is sufficient, with strong coworking infrastructure to match.
Since this is a 1099 independent contractor arrangement accepted globally (local equivalent outside the US), it pairs well with digital nomad visas in countries like Portugal, Spain, Costa Rica, or Georgia. No benefits are provided, so budget for private health insurance. The writing-focused, asynchronous nature means a stable internet connection is your only logistical requirement.
Headquarters: Atlanta, AZ.

TrainBrain builds expert-authored training data and evaluations for AI labs. We're hiring practising professionals in three domains to write, solve, and grade the problems frontier models are measured against.
We're hiring domain specialists in:
- Finance & Accounting — accountants, financial analysts, controllers, auditors
- Software Engineering — working engineers across languages and problem domains
- Medicine & Healthcare — physicians, pharmacists, nurses, and clinical researchers
No AI background required. We train you on the tooling.
What you'd actually do
Every model that returns a broken function, a wrong reconciliation, or an unsafe clinical suggestion got there because no expert caught it during training. You'd be that expert.
- Write hard, realistic problems from your domain — the kind that sit right at the edge of what current models can handle
- Solve them yourself, so there's a verifiable correct answer
- Grade model attempts and explain precisely where the reasoning breaks down
- Refine tasks until both the difficulty and the gradability are right
This isn't your day job in a new wrapper. No clients, no month-end close, no tickets, no on-call. It's written work, on your own schedule.
What we look for
Deep hands-on experience in your field, excellent written English, and sharp attention to detail. Credentials help — CPA, CA, ACCA, CFA, MD, MBBS, PharmD, RN, a CS degree — but demonstrated expertise counts more than any specific letters. Above all, we want people who show their work and are comfortable saying "I'm not sure, and here's why."
Terms
- Pay: $45–$100/hr, set by domain, seniority, and assessment performance. Specialised and hard-to-source expertise sits at the top of the band. Paid on a regular cadence.
- Schedule: You choose your projects, hours, and volume. Scale up in quiet weeks, scale down when your day job gets busy.
- Growth: Strong contributors move into higher-rate specialist projects and review roles.
- Structure: 1099 independent contractor (or the local equivalent outside the US), not W-2 employment. You handle your own taxes; company benefits don't apply.
