[Hiring] Founding CTO @Red Cell Partners

Role Description

MyPattern's beta is live. Real users are in the product. Now we need the hands-on engineering leader who will take it from here.

As Founding CTO, you'll partner directly with our founder to scale and deepen the platform that's already in users' hands. This is a high-impact, founder-level role — you're not starting from zero, but you're shaping everything that comes next. You'll inherit and evolve a live codebase, accelerate feature development, and harden the infrastructure as we grow from beta into our full product launch.

Expect to wear many hats, move fast, and have significant influence over our product, team, and company as we scale. The technical decisions you make now will define MyPattern for years.

What You'll Do

• Take Ownership of a Live Product: Inherit a working beta with real users and make it better — faster, more reliable, and more capable. Assess the existing architecture, close gaps, and build on a foundation that's already delivering value.
• Architect the Health Intelligence Engine: Evolve and deepen the backend infrastructure, APIs, and data models that power personalized health insights. Design systems that synthesize lab results, wearable data, symptoms, and medical history into actionable intelligence at scale.
• Develop and Extend Data Integration Pipelines: Build on and expand robust ETL pipelines ingesting data from diverse sources: lab providers (Quest, LabCorp), wearables (Oura, Apple Health, Whoop, Garmin), medical records, and user-entered data. Ensure data integrity, security, and HIPAA compliance.
• Build AI-Powered Features: Implement and refine the conversational AI health check-ins, treatment recommendation engine, and predictive models that surface insights and guide users through their health journey. Work with Claude and other AI tools to accelerate development.
• Own Security and Compliance: Build with HIPAA compliance as a first-class concern. Implement and maintain encryption, access controls, audit logging, and security best practices for handling sensitive health data.
• Leverage AI-Native Development Tools: Use Claude, Claude Code, Cursor, and other AI-assisted development tools to accelerate building. Embrace vibe coding and rapid prototyping to move quickly from concept to working product.
• Technical Leadership: As we scale, mentor and guide additional engineers. Help establish engineering culture, practices, and standards. This role has a clear path to engineering leadership.

Qualifications

• 10+ years of software engineering experience, with a track record of building and shipping complex products.
• Strong backend and infrastructure expertise. Deep experience with system architecture, APIs, databases, and building scalable, reliable systems. Comfortable with Python, Node.js, or similar.
• Experience with health data and integrations. Worked with lab data, EHR systems, wearable APIs, or healthcare interoperability standards (HL7, FHIR).
• Data pipeline and ETL experience. Built pipelines that ingest, transform, and normalize data from multiple sources.
• Cloud infrastructure proficiency. Hands-on experience with AWS, GCP, or Azure.
• AI/ML implementation experience. Built products that leverage AI—whether recommendation systems, NLP, conversational AI, or predictive models.
• Security and compliance mindset. Understand HIPAA requirements and can build systems that protect sensitive health data from the start.
• Comfortable with AI-native development workflows. Use Claude Code, Cursor, GitHub, or similar tools to accelerate your work.
• Startup mentality. Thrived in early-stage environments where you wear many hats, move fast, and take ownership.
• Passion for the mission. Care about building technology that improves women's health outcomes.

Benefits

• Career track opportunity with potential for rapid advancement with strong performance as the firm grows.
