Software Engineer, Model Lifecycle and Signals
Cursor, New York, NY +1
The role
As a Software Engineer on the Model Lifecycle and Signals team at SpaceXSI, you'll own the bridge between frontier models and every user-facing Cursor product, used at a scale few teams ever see. You'll decide when we use which model, spot where models go off track and build the guardrails to keep them on it, and shape what the next generation of models should learn. This role sits at the intersection of infrastructure, data, and product: you'll bring models from preview to production, dig into real-world data to find out what's actually working, and partner with research, inference, product, and data science teams to turn that evidence into better products and better models.
Every improvement you make compounds across our products and every model we ship.
What you will do
- Get new frontier models into users' hands the day they're ready, and retire old ones without anyone noticing
