Voice response instructions

Responses may be up to one minute long. A few sentences are sufficient if that feels natural.

Good to know if you are moving

All Spain-based roles are fully remote, offering flexibility for international professionals.
The company hires domain experts (e.g., mathematics, physics, biology) to train AI models, making it a unique opportunity for academics and specialists.
As a US-based company, salaries and contracts may be structured under Spanish employment laws, but specifics should be confirmed during the hiring process.
The company is small, so employees may have a direct impact on AI training processes and product development.
Working with a US-based company from Spain may require managing time zone differences, though remote work mitigates this.
