## Job Description
## What You’ll Do

- Own research initiatives end-to-end, including problem formulation, experimental design, modeling, and evaluation
- Develop novel architectures, training methods, and objectives leveraging longitudinal patient data
- Work on verifiable reinforcement learning, mid-training, and post-training of foundation models
- Design rigorous evaluation methodologies to assess model reasoning, correctness, and clinical relevance
- Make and own tradeoffs between model capability, interpretability, and verifiability in high-stakes settings
- Collaborate with clinicians and engineers to define meaningful problem formulations grounded in real-world workflows
- Partner with ML engineers to ensure research translates into deployable systems

## What We’re Looking For

- Strong foundation in machine learning, deep learning, or a related technical field
- Track record of driving ML research or novel modeling work from idea to validated results
- Experience working on ambiguous research problems with limited prior art
- Hands-on experience with **PyTorch** or similar frameworks
- Ability to operate independently in high-ambiguity environments with minimal guidance
- Strong technical judgment — you can identify meaningful problems, design appropriate approaches, and evaluate results rigorously
- Comfort working in a fast-moving, early-stage environment
- Experience working on systems where decisions have real-world consequences (e.g., healthcare, finance, infrastructure)

## Nice to Have

- Publications at top-tier ML venues (e.g., NeurIPS, ICML, ICLR)
- Experience with **LLMs**, **NLP**, or sequence modeling
- Experience with **reinforcement learning** or alignment methods
- Experience working with longitudinal or structured data at scale
- Experience working with clinical, biomedical, or scientific domains

## Compensation

**Base salary**: $225,000 – $300,000+
Meaningful equity in an early-stage, Series A company
