Depends on the layer. RLHF and SFT specialists produce the training signal — preference rankings, instruction-response pairs, rubric scores. Prompt engineers and evaluators shape and measure model behavior with golden datasets and regression suites. Red teamers attack the system to find jailbreaks and injection paths. RL environment engineers build the containerized tasks and verifiable rewards that agentic training runs on. Most teams need two or three of these profiles, not one generalist. ### ### How much do LATAM LLM specialists cost? Data annotation and collection start at $18/hr, prompt engineering around $22/hr, SFT $23/hr, RLHF $26/hr, model evaluation $25/hr, red teaming $28/hr, RL environment engineering $32/hr, and credentialed domain experts $35–70/hr depending on the field. That is typically 50–70% below equivalent US rates for the same seniority bar. ### ### Are your LLM specialists bilingual? Yes. B2+ English is the floor for every profile and C1+ is required for evaluation, red teaming and domain-expert work where nuance decides the label. Native Spanish and Portuguese is the reason many clients hire here in the first place: multilingual safety and quality data written by native speakers, not translated from English. ### ### Can I start with a small pilot before committing to a pod? Yes. The usual path is a 3–10 person pilot for four to six weeks: week one to align rubrics and build the golden set, week two to calibrate until agreement clears the threshold, then production throughput. If the quality bar is met you convert to a dedicated pod; if not, you stop. ### ### How do you guarantee annotation quality? Golden sets seeded into the live queue, inter-annotator agreement tracked continuously (κ ≥ 0.80 on most task types), dual review on high-stakes labels, and weekly quality reports you can audit. Contributors below threshold are recalibrated or replaced at our cost. ### ### How fast is the shortlist? A vetted shortlist in 5 business days after the role brief. No upfront fee; staffing includes unlimited replacements during the engagement and direct hire a 90-day replacement guarantee. ## Ready to Accelerate Your LLM Career?
