hn · Hybrid ONSIDE 1-2 days/wk Bay Area · $200k-$250k
Jose is a strong generalist engineer with proven full-stack expertise across frontend, backend, infrastructure, and AI/ML systems. His experience building production AI products (real-time voice, LLM agents) and working with frontier AI models demonstrates the exact technical depth and product sense Prolific needs. The main gap is direct experience with human data infrastructure, quality assurance systems, or research data pipelines, which are core to Prolific's mission.
Hook: Your founding engineer experience shipping production AI systems at scale directly translates to architecting reliable infrastructure for frontier AI companies—exactly what Prolific needs to revolutionize human data collection.
Missing: human data labeling/annotation systems, research data quality assurance pipelines, crowdsourcing platforms, survey/research methodology expertise
