About the Role

A startup generalist is the Swiss Army knife of an early-stage team, building the glue between product, growth, support, and operations while processes are still forming. In Brazil, remote-ready talent in hubs like Sao Paulo, Florianopolis, and Recife supports globally distributed, AI-first startups.

Key Responsibilities

Create SOPs from scratch, triage across functions, and ship whatever the week demands—onboarding flows, data cleanup, growth experiments, or labeling and QA support. Translate founder priorities into concrete execution and keep information and processes clean as the team scales.

Required Skills

Comfort with ambiguity, structured thinking, and fast, clear communication are core. Bilingual pt-BR/English fluency helps with coordination and multilingual annotation. Resourcefulness with lightweight tools and a documentation habit complete the profile.

Preferred Experience

Early-stage, operations, or high-growth experience helps, as does any hands-on labeling, annotation, or evaluation work. A record of building something from zero signals the range these roles reward.

Domains & Project Types

Work spans operations and coordination, data labeling and QA, RLHF and prompt design, NER, and computer vision annotation—often close to a startup's own data pipelines. Generalists sample domains fast before specializing.
