Machine Learning Engineer

Superhuman offers a dynamic hybrid working model for this role. This flexible approach gives team members the best of both worlds: plenty of focus time along with in-person collaboration that helps foster trust, innovation, and a strong team culture.

We’re looking for a foundational Machine Learning Engineer to join our team in Porto and build the evaluation foundation behind the next generation of AI-native productivity at Superhuman, specifically our agent platform, where multiple AI agents collaborate to solve complex user problems. You’ll own how we define, measure, and improve quality. You’ll build the eval datasets, the infrastructure around them, and the metrics that tell us whether our models and agents are actually getting better for users.
