CTO​/Co-founder; Digital Health, Ambient AI​/ML, Mobile

Alloy Partners is a venture builder with a radical thesis: that we can build and scale advantaged companies in partnership with corporations and entrepreneurs.

Alloy Partners and the University of Notre Dame partnered to establish a first-of-its-kind venture studio (the 1842 Studio) and venture fund (the 1842 Fund) that aligns with Notre Dame’s mission of serving as a “Force for Good” in the world. In close partnership with the University and its vast “ND Family” of alumni, corporate, community, and academic leaders, the 1842 Studio aims to co-create startups that address important societal challenges, such as improving health access and outcomes for our most vulnerable populations.

We are seeking a CTO & Co-Founder to own Stealth Co’s technical vision, architecture, and execution from MVP through scale. This is a rare opportunity to build a category-defining healthcare AI platform from the ground up, working closely with a world-class clinical partner and shaping the long-term product, data, and AI strategy of the company.

Stealth Co is an AI-powered recovery and discharge platform addressing the hospital capacity crisis by helping patients recover faster and care teams work more efficiently. Using ambient listening and AI, Stealth Co captures patient - care team conversations and translates them into personalized recovery tasks, goals, and guidance for patients and caregivers, while giving care teams real-time visibility without adding work.

Stealth Co is building its MVP in partnership with a top medical academic center, with the goal of validating measurable reductions in length of stay, improved patient experience, and reduced care team burden.

As CTO & Co-Founder, you will be responsible for designing, building, and scaling Stealth Co’s technology platform, while serving as a strategic partner to the CEO. You will lead all technical decisions across application architecture, AI/ML systems, integrations, security, and compliance, initially as a hands‑on builder, and over time as a technical leader who hires and mentors a world‑class team

This role is ideal for a builder who thrives at the intersection of AI/ML, healthcare systems, and real‑world product delivery, and who wants true co‑founder ownership.

• Define and own Stealth Co’s end‑to‑end technical architecture, including:
  Patient and care team applications (likely PWA‑first)
• Ambient listening and speech‑to‑text pipelines
• AI/ML systems for task extraction, summarization, and conversational AI
• Data storage, deployment, and retention strategies aligned with health system requirements
• Make pragmatic build vs. buy decisions (e.g., Whisper/Azure, LLMs, NLP tooling, vendors).
• Design for device‑agnostic use across smartphones, tablets, and in‑room hospital displays.
  Establish a scalable foundation that can evolve from MVP to enterprise deployments across health systems.

• Personally build and ship large portions of the MVP during the Design Partnership Build phase.
• Implement real‑time or near‑real‑time ambient audio capture, transcription, and summarization.
• Build text‑to‑text pipelines that convert transcripts into patient recovery tasks and insights.
• Support early integrations with Design Partner’s infrastructure and EHR (e.g., in‑room displays, Epic, ambient listening hardware like Hellocare).
  Ensure the MVP can reliably measure product and outcome metrics (e.g., LOS reduction, activation rates).

• Architect the AI stack, including:
• Speech‑to‑text ingestion
• Task extraction and goal linkage using LLMs and medical NLP
• Retrieval‑augmented generation (RAG) grounded in health‑system‑approved content
• Design guardrails, prompt strategies, and evaluation frameworks to ensure safe, reliable, patient‑facing AI.
• Plan for future AI capabilities such as predictive discharge readiness, readmission risk, and care team AI agents.

• Own HIPAA‑compliant system design across data collection, storage, transmission, and access.
• Implement patient consent flows for ambient listening and AI use.
• Define data de‑identification, access controls, audit logging, and…
