We are looking for a Research Scientist to help build next-generation foundation models for tabular data, time series, and ultimately the broader world of structured data.

\n

Our goal is to make powerful machine learning dramatically easier to use, customize, and deploy across real-world applications and enterprise environments.

\n

This is a high-ownership, high-freedom research role. You'll drive your own research agenda across model architecture, pretraining, synthetic data, and evaluation. You'll own training runs end to end—from the initial idea and ablation studies to analysis and technical writeups. Just as importantly, you'll learn alongside your colleagues: a negative result is information, not a failure.

Responsibilities

\n

\n

• \n
• Design and run experiments on model architecture, including attention mechanisms, normalization, positional schemes, optimizers, and the in-context learning machinery that makes tabular foundation models work.
• \n
• Own pretraining runs end to end—launch them, profile them, debug loss curves, and understand why the model behaved the way it did.
• \n
• Design synthetic data generation strategies, including priors, sampling, and reweighting choices that determine what the model can and cannot generalize to.
• \n
• Build evaluation systems that measure meaningful performance. Design benchmarks, select appropriate scoring rules, run statistical analyses rigorously, and identify when a result is unexpectedly strong or potentially misleading.
• \n
• Extend models to new modalities.
• \n
• Stay closely engaged with current research and translate it into concrete decisions: determine which recent techniques are worth testing in our environment and which results may not translate beyond the original paper.
• \n
• Write up research findings through internal reports, white papers, and technical blog posts, communicating clearly with engineers, customers, and reviewers.
• \n
• Help define the research roadmap and make foundational modeling decisions.

Qualifications

\n

\n

• \n
• A strong publication record in machine learning or an equivalent public body of work, such as open-source models, technical reports, or reproducible results that have gained recognition. A PhD is preferred but not required.
• \n
• Hands-on experience training large-scale models. You have owned multi-GPU or multi-node pretraining runs and understand the stability, throughput, and data-pipeline challenges involved.
• \n
• Comfortable reading and modifying attention kernels, developing custom modules, and profiling systems to identify performance bottlenecks.
• \n
• Deep familiarity with transformer internals and the trade-offs associated with different architectural choices.
• \n
• Strong written and verbal communication skills. You can explain technical mechanisms precisely without relying on vague explanations and can communicate effectively with both technical and cross-functional colleagues.
• \n
• Comfortable working in an early-stage environment where priorities evolve and requirements are not always fully defined.

• \n
• Experience with tabular foundation models or in-context learning.
• \n

• \n
• Experience with synthetic data generation for pretraining.
• \n
• A track record of open-source contributions or maintaining research code.
• \n
• Previous experience at an early-stage startup or as part of a founding team.
