About this role

From the Mercor listing

Mercor is partnering with a leading legal AI company to benchmark how well AI systems answer real questions of Spanish law. We are hiring experienced in-house counsel to serve as expert reviewers — running the same prompts through two AI platforms, comparing the answers, and scoring them against a standardized rubric.

What you'll do

  • Run the same set of prompts across two AI (LLM) platforms
  • Compare the outputs from both platforms side by side
  • Score each response against a standardized rubric we provide
  • Submit concise written feedback for every evaluation

Requirements

  • 5+ years as in-house legal counsel practising in Spain
  • Strong command of Spanish law, especially commercial and contract matters
  • Sharp attention to detail and precise written communication
  • Able to work independently to a rubric and to deadlines

Logistics

  • Initial commitment: ~10 hours, with strong potential for more
  • Confidentiality: all work is covered by NDA

Why this role

Common questions

Is Mercor for freelancers or full-time contractors?

Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.

Does Mercor's application require an on-camera interview?

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

Why do these AI training roles pay so much?

Because general knowledge isn't what's being tested. The model already knows the basics; what it needs is expertise on edge cases, the rare, difficult, highly technical judgment calls only a senior professional in the field would make correctly.

What does the day-to-day workload look like for elite-expert AI training roles?

Slow and deep, not fast and repetitive. A single task can take 45-60 minutes of researching citations or verifying complex calculations. Quality is what's being measured here, not throughput.

What does Languages work look like for an In-House Counsel (Spain)?

Tasks here are scoped to Languages, not generic labeling. As an In-House Counsel (Spain), expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Languages) rather than following a one-size-fits-all rubric. If you don't have hands-on Languages background, this is likely not the right listing to start with.

What specific skills does this listing call for?

Spanish and Expert are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.

How much does this specific role pay?

This listing is posted at $140–$150/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

Do I need to be fluent in Spanish?

Yes. This role specifically requires Spanish proficiency, on top of the English most AI training work assumes by default. If Spanish is not a language you're fluent in, this is not the right role. Filter for your native language to find better-matched listings.

What happens when I click Apply on this listing?

You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

Can I apply from outside Spain?

This specific role is open only to people based in Spain. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.

How soon will I start working after applying to Mercor?

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
