Senior Applied Scientist - Behavior AI

Job summary

Responsibilities

We are hiring a Senior Applied Scientist to build these models from start to finish. You will contribute to designing the architecture, training at scale, and the optimization work that takes a model from training to running efficiently on production traffic.

• Design and build custom mid-size models for high-throughput stream processing, and train them at scale.
• Optimize these models from start to finish, working across both the mathematics and the systems, often by finding mathematical reformulations that fit the hardware and software…
• Build the training data pipelines the work depends on when they do not already exist, from the raw stream to a training-ready dataset.
• Work with engineering to integrate models into production, with a clear focus on GPU utilization, latency, and cost per record on live traffic.
• Plan the roadmap of model and system improvements, based on a solid understanding of the product and of what matters most to users.

What they're looking for

• You have a BS/MS/PhD in Computer Science, Engineering, Machine Learning, Applied Mathematics, or a related scientific field, or equivalent experience.
• You have hands-on experience training and fine-tuning models at scale, and deploying them into production systems with real throughput and cost constraints.
• You have a working knowledge of how GPUs work, and a track record of making models run efficiently within real hardware constraints.
• You have strong applied-mathematics fundamentals and reach for them naturally when designing and optimizing models.
• You have a real passion for applied mathematics, software design, and implementation. This role sits at the intersection of the three, and it is a requirement for the position.
