- Translate exploratory R&D concepts (mental health screeners, GLP-1 integrations, clinical adjacencies) into production-quality experiments.
- Serve as the day-to-day technical interface with the client's team, coordinating work with the client PM and ensuring Senior team members are productive.
- Lead technical design, planning, mentoring, and delivery of complex initiatives across the three workstreams.
