Role Overview
We are seeking a hands-on Senior Engineer to build new critical systems and scale our clinical trial recruitment platform.

- Small team comfort: excited to wear many hats and thrive without rigid role boundaries
- High autonomy: as the second backend engineer, work directly with a Staff Engineer and influence technical direction
- Hands-on mentality: engineer-first who writes code daily
- 0-1 building experience: taken something from idea to production
- Systems thinking: strong understanding of backend architecture, APIs, databases, and scalability
- Communication skills: able to explain technical tradeoffs and work cross-functionally
- Healthcare alignment: genuinely interested in improving clinical trial access and health equity
