Co budeš dělat
- Build production augmentation and profile models: Design, train, evaluate, and deploy models against real survey data, owning the full path from experiment to production.
- Innovate on solutions: We aim to build the best simulation of survey responses in the industry. You'll design the experiments, baselines, and models to get us there.
- Use the latest technology: Build on the best open-weights LLMs with fine-tuning, build new ones from scratch with custom architectures or use third party models through an API; whatever gets us the best result.
- Partner with Data Science: Work with the data science team to ensure integrity of our statistical testing and experiment framework.
- Leverage AI tooling: Use Claude Code and agentic programming tools where appropriate.
