The Role
As part of NewtonX's growing Medellín engineering hub, you'll design and build the fast, reliable, modular user interfaces that power our research platform — sophisticated web applications, reusable component systems, and data-rich experiences built on top of our APIs. You'll work on a small, fast-growing engineering team (under 40 engineers) where individual contributors get in early and help shape the direction of our technology.




This role partners closely with US-based engineering leadership and cross-functional teams. Fluency and confidence in English, written and verbal, is essential — you'll participate in technical reviews, planning, and design discussions with colleagues across time zones.
