What is a Machine Learning Engineer at Superhuman?
At Superhuman, the Machine Learning Engineer role is at the absolute center of our mission to build the fastest, most delightful, and most intelligent email experience in the world. Email is the nervous system of modern business, and our users expect an inbox that doesn't just display messages, but actively helps them fly through their work. As an MLE, you will build the intelligent systems that power features like Superhuman AI, auto-summarization, instant draft generation, semantic search, and highly accurate spam and triage classification.
This is not a role where you will build models in isolation. At Superhuman, machine learning is deeply integrated into the core product, meaning your work directly impacts user experience, latency, and day-to-day productivity for tens of thousands of professionals. You will tackle complex challenges at the intersection of natural language processing (NLP), large language models (LLMs), and high-throughput backend systems. Because speed is our primary value proposition, you will constantly design solutions where model performance and sub-100ms latency must coexist.
To succeed in this role, you need a rare combination of strong software engineering fundamentals, deep machine learning expertise, and a passionate product-focused mindset. You will design, train, deploy, and monitor models that operate on highly sensitive, real-world communication data. It is a highly collaborative role where you will partner closely with product managers, frontend engineers, and security teams to deliver AI features that feel like magic.
