Model Lifecycle & Signals Engineer | Scale Frontier AI

Cursor; New York, San Francisco (NY, CA); In loco; USD 180.000 - 240.000; Tempo pieno

Descrizione del lavoro

SpaceXAI in the United States seeks a Software Engineer for the Model Lifecycle and Signals team to bridge frontier models with Cursor products at scale. You’ll decide model usage, detect drift, and shape the next generation of models.

This role sits at the intersection of infrastructure, data, and product, turning evidence into better products and models. You’ll work with research, inference, product, and data science teams to bring models from preview to production, build guardrails, and ship

Competenze

• You're an exceptional engineer with a track record of shipping production systems people rely on.
• You've built and operated evaluation, measurement, or model serving systems and can turn ambiguous quality questions into metrics, pipelines, and decisions.
• You're fluent with data and can collaborate effectively with data scientists and researchers.
• You have strong taste and real curiosity about model and agent behavior.

Mansioni

• Get frontier models into users' hands the day they're ready and retire old ones without being noticed.
• Evaluate internal and external preview models before launch and give meaningful feedback to the teams building them.
• Build Cursor Router to decide which model handles each request, balancing quality, speed and cost at massive scale.
• Build the eyes and ears of the product and the experimentation platform that shows where each model shines and where it goes off track.
