This is a unique, entrepreneurial role where you will drive real value by combining scientific rigor with a business-focused approach to advance our AI Agent and Decision Hub capabilities
What you'll be doing:
Designing and building agents in high-consequence environments, where outputs need to be validated to a high standard
Performing exploratory data analysis, model building, validation, and performance monitoring.
Leading data science efforts within cross-functional delivery teams—partnering with engineers, designers, and product leads for successful outcomes.
Understanding deeply core customer problems to ensure technical solutions drive real value
Translating real-world problems into technical strategies and measuring model impact with scientific rigor
Who we're looking for:
You have senior-level experience in data science or quantitative research
You’re proficient in Python and essential libraries (NumPy, Pandas, scikit-learn), plus familiarity with a deep-learning framework (e.g., TensorFlow, PyTorch)
You possess a strong foundation in statistics and mathematics
You’re experienced across the full data science toolkit—including supervised/unsupervised learning, time-series, Bayesian methods, and model validation—and can develop new algorithms when needed
You bring a leadership mindset centred on technical excellence, team growth, and a collaborative culture
You exhibit scientific rigor and a business-focused approach: translating problems into technical strategies and measuring model impact.
You’re product-oriented, deeply understanding user needs and how Frontier can deliver value to them
It would be great if you had experience building and evaluating agents using eval-driven development (although not a must-have)
