Founding Engineer (potential CTO)

Meo Health is hiring a Founding Engineer (potential CTO) to be the second technical voice and turn our product vision into a production-quality AI mobile experience; this role is early-stage, in-person in Montreal, SF, or NYC, and central to how we build for the next decade. You’ll ship the first Meo AI end-to-end experience, design the model and feedback loop for a nervous system training coach, and define the engineering culture and stack.

What you'll do

• Serve as the Founding Engineer and potential CTO, owning technical direction and execution.
• Ship Meo AI v1 end-to-end, from React Native app to Claude-backed inference and wearable integrations.
• Architect and build the nervous system training AI coach, including model design, prompt engineering, and evaluation.
• Translate biosignals (HRV, breath, motion, PPG) into a real-time coaching layer that meets users where they are.
• Build and maintain AI-powered QA and testing pipelines to enable safe daily shipping.
• Own the full stack decisions across frontend, backend, infra, and AI-native layers.
• Integrate iOS/HealthKit and wearable platforms (Apple Watch, Oura, Whoop, EEG headbands).
• Work on-site in Montreal, San Francisco, or New York to collaborate closely with the founding team.

What Meo Health is looking for

• Proven experience shipping a 0→1 consumer mobile app that served real users.
• Deep fluency in React Native and ownership of the full mobile lifecycle (build, release, debug, monitor).
• Production experience building with Claude or other frontier models, including prompts, tool use, and evals.
• Comfortable moving across frontend, backend, infra, and AI infrastructure without hesitation.
• Experience with or strong ability to learn HealthKit, wearable APIs, and handling noisy biosignal data.
• Founder mindset with prior first-engineer or early-stage startup experience and the ability to make hard tradeoffs.
• Ability to be in-person in Montreal, SF, or NYC.
• Background or strong interest in nervous system science, somatics, neuroscience, or trauma research.
