Problem-Solving & Autonomy: Proven ability to resolve complex technical issues on-site without heavy reliance on escalation channels.
Language Proficiency:
Fluent in Spanish (for daily collaboration with local operational teams).
Professional working proficiency in English (for reporting to Infarsight and partner leadership).
Location & Mobility: Based in or willing to relocate to Santiago, Dominican Republic. Full availability for daily on-site presence at Arena during Phase-1, with flexibility to visit additional facility locations as the project scales.
