Data Scientist II

The Data Scientist II

Analyze data to support (or disprove) a thesis – You'll dig into data, form hypotheses, and let evidence guide your conclusions. We value intellectual honesty over confirmation bias.

Select and implement the right tools for the job – Not every problem needs a transformer. Some problems just need a well-tuned gradient boosting model. You'll know the difference.

Build, train, s, and validate models – From algorithm selection to hyperparameter tuning to rigorous evaluation. You'll need solid grounding in math and statistics to evaluate model performance and defend your choices.

Engineer models into production – This isn't research for research's sake. Your models need to run reliably in the real world, on real infrastructure, serving real customers.

Document your work – Future you (and your teammates) will thank you. We maintain clear documentation for models, sing protocols, and decision rationale.

Monitor and improve models in production – Models drift. Data changes. You'll keep watch and know when it's time to retrain, rebuild, or rethink.

Explore agentic and reasoning systems – We're investing in semi-autonomous systems that can plan and act. You'll help us figure out what's hype and what's actually useful.
