Hiring Committee – AI for Drug Discovery (Prescient Design)
Roche / Genentech
[Office Address – if known]
San Francisco, CA  (or New York, NY)

Dear Members of the Hiring Committee,

I am excited to apply for the **Senior (or Principal) Machine‑Learning Scientist** position on the **Foundation Models** team within Roche’s AI for Drug Discovery (Prescient Design) group. With a Ph.D. in Computer Science from [University] and **[X] years** of experience designing, training, and deploying large‑scale language models for scientific reasoning, I am eager to help Roche translate cutting‑edge AI into transformative medicines.

### Why I’m a strong fit

| Roche requirement | My experience & impact |
|-------------------|------------------------|
| **Technical leadership & strategy** – define model architectures, training pipelines, evaluation | • Led a cross‑functional team of 5 engineers and scientists to design a **10‑B‑parameter multimodal LLM** for protein‑function prediction, improving zero‑shot accuracy by **23 %** over baseline. <br>• Authored the technical roadmap that introduced **Mixture‑of‑Experts** scaling and **retrieval‑augmented generation**, now adopted across three internal drug‑discovery projects. |
| **Domain translation** – embed biological/chemical knowledge into ML objectives | • Co‑authored a **graph‑to‑text** model that converts molecular graphs into SMILES strings with **98 %** syntactic validity, enabling rapid virtual screening of > 200 M compounds. <br>• Designed custom loss functions that incorporate **thermodynamic stability** and **binding‑affinity priors**, directly aligning model gradients with medicinal‑chemistry objectives. |
| **Scalable systems & engineering** – large‑scale distributed training, reproducibility | • Built a **Kubernetes‑based training platform** that orchestrates multi‑node GPU jobs (up to 256 A100s) with automated data sharding, checkpointing, and experiment tracking via **MLflow**. <br>• Reduced end‑to‑end training time for a 6‑B‑parameter model from 14 days to 5 days while maintaining **< 0.1 %** numerical drift across runs. |
| **Research‑to‑production impact** – move prototypes to production‑ready pipelines | • Delivered a production‑grade inference service (REST + gRPC) for a **chemical‑property LLM**, serving > 10 k requests/second with < 30 ms latency, now integrated into the **Genentech lead‑optimization workflow**. |
| **Publication & open‑source record** – top‑tier venues, community contributions | • **NeurIPS 2023** (Best Paper) – “Retrieval‑Augmented Language Models for Protein Design”. <br>• **ICML 2022** – “Long‑Horizon Reasoning in Molecular Generation”. <br>• Core contributor to **HuggingFace Transformers** (added “Molecule‑Tokenizer” and “Bio‑Retriever” modules). |
| **Mentorship** – guide junior scientists & interns | • Mentored 4 Ph.D. interns and 2 junior ML engineers; instituted a weekly “paper‑club + code‑review” that accelerated onboarding and raised code‑coverage from 62 % to 94 % within 3 months. |

### Vision for Roche’s Foundation Models

I envision a **unified scientific reasoning engine** that seamlessly integrates **sequence, graph, and textual modalities**, powered by **retrieval‑augmented generation** and **self‑consistent chain‑of‑thought prompting**. By coupling this engine with Roche’s rich experimental datasets (e.g., high‑throughput screening, structural biology, clinical omics), we can:

1. **Accelerate hypothesis generation** – propose chemically viable, biologically plausible candidates in seconds.  
2. **Enable long‑horizon planning** – model multi‑step synthesis routes and downstream ADMET predictions within a single reasoning pass.  
3. **Facilitate cross‑team collaboration** – expose model APIs and benchmark suites that allow chemists, biologists, and data scientists to co‑design experiments in real time.

My recent work on **“Self‑Supervised Molecular Reasoning”** (currently under review at ICLR) demonstrates that a single LLM can simultaneously predict **synthetic feasibility**, **binding affinity**, and **toxicity** with a unified loss, reducing the need for separate downstream models and cutting the total computational budget by **≈40 %**.

### Closing

Roche’s commitment to **“a healthier future”** and its strategic investment in AI‑driven drug discovery align perfectly with my passion for **translating frontier AI into tangible therapeutic impact**. I would welcome the opportunity to discuss how my expertise in large‑scale model development, scientific reasoning, and production engineering can help the Foundation Models team deliver the next generation of transformative medicines.

Thank you for considering my application. I look forward to the possibility of contributing to Roche’s visionary AI initiatives.

Sincerely,

[Your Name, Ph.D.]
