This is an early, high-impact role. You’ll work directly with the CEO and help build the company from the inside.
Job Overview
What you’ll do:
- Partner closely (on a daily basis) with the CEO on all aspects of running the business.
- Support the CEO in prioritization, communications, and time allocation to ensure focus on the most critical initiatives.
- Run weekly exec cadences, project trackers, and help prep internal and external communications.
- Support go-to-market execution: sales ops, outbound campaigns, deal support.
- Manage and maintain relationships with hospital customers and partners.
- Support fundraising: investor pipeline, updates, and diligence prep.
- Keep visibility on company finances: expenses, vendors, basic accounting.
- Support regulatory execution (FDA / CE): timelines, documentation, coordination
What You’ll Gain
- Front-row seat to building a YC-backed deep-tech company from zero to scale
- Daily exposure to high-stakes decisions: hospitals, regulators, investors, and product all at once.
- The chance to become one of the core operators of the company, not a support role.
- Ownership that compounds: the more you deliver, the bigger your scope becomes.
- A trajectory toward senior leadership as we scale.
About You
- Proven track record of building/scaling a business/project. We don’t care whether your background is business, technical, or something else.
- You are based in SF or willing to relocate within this year (we can support O-1).
- You’re willing to work in person and travel when needed.
- Proven ability to manage multiple priorities in a fast-paced, dynamic environment. Instinct for early-stage scrappiness & hustle.
- Strong work ethic & execution velocity.
Nice to have (not required)
- Experience with hospitals, healthcare procurement, or medical sales.
- Background in, or passion for, SaaS, AI, or technology companies.
- Medical training (MD, med student, or formal education in medicine / biomedical sciences).

Nucleo is an AI-first medtech startup building the first agentic platform for oncology CT scans.
Our mission is simple and ambitious: reduce the time from cancer diagnosis to treatment from ~10 weeks to ~10 days by automating the most time-consuming, manual steps in the clinical workflow.
Today, hospitals still rely on radiologists and oncologists to manually extract critical information from CT scans - body composition, sarcopenia, tumor measurements, RECIST classification. This is slow, expensive, and error-prone. We replace these steps with AI agents that read CT scans end-to-end and generate structured, clinically useful outputs in seconds.
We work with top-tier hospitals in the US and Europe (including Stanford, Cedars-Sinai, UCI Health, and Weill Cornell) and are building toward FDA-cleared clinical software used directly in real oncology workflows.
We operate in a high-ownership, early-stage environment focused on shipping reliable AI into real clinical practice.
