Summary
🤩
Rockstar🎓
Top SchoolSimone Primarosa is a machine-learning-focused software engineer with 11 years of experience building scalable systems across startups and large tech companies, currently a founding member of the technical staff at Boltz after several senior engineering roles at Google. He has deep expertise in search ranking, distributed data processing (contributions to Apache Beam’s Go SDK), and practical ML tooling (improvements to the widely used Hugging Face transformers examples). A First Class BSc from Sapienza and an MPhil in Advanced Computer Science from Cambridge underline a strong research foundation that complements hands-on product delivery—from launching features in Google Maps to architecting Busrapido’s platform that served tens of thousands of users. Comfortable across languages and stacks (Go, Java, JavaScript, PyTorch), he combines production-grade engineering with a researcher's attention to model and system correctness. Less obvious: he has repeatedly bridged research and production, fixing bugs in major embedding frameworks and shipping instrumentation and logging improvements that make ML experiments and pipelines more reliable.
