NewtonX, Medellín, Colombia
About the job
NewtonX (600+ clients like TikTok, Microsoft, Salesforce, Bain, Figma and many more) is a research intelligence company helping organizations make better business decisions and train better AI models through verified human intelligence.
We turn specialized human expertise into reliable business decisions (e.g., product launches, marketing strategy, brand reputation tracking, M&A due diligence) and AI training data (frontier model improvements and evals).
We have several million domain experts that we have sourced over the last few years (150+ industries including finance, legal, coding, tax & accounting, healthcare, semiconductors, cybersecurity, STEM and more).
We have worked with AI Labs and Enterprises on topics ranging from sourcing senior electrical and SW engineers for a chip design benchmark to pediatricians and psychiatrists for clinical data to ML engineers and PhD-level statisticians proficient in 3D modeling.
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.
