Technical Co-Founder/CTO in Plymouth

Technical Co-Founder / CTO – Health-Tech & Sports Performance

I’m looking to bring on a Technical Co-Founder / CTO to help build EXRT, a health & sports-tech startup focused on ECG-driven physiological and performance analytics for athletes and teams.

EXRT’s direction is now clearly defined following practitioner-led validation and recent angel funding, with a larger upcoming raise planned once key technical milestones are delivered. This next phase requires a committed technical partner to own the architecture, data pipeline, and technical roadmap alongside me.

About EXRT

EXRT is a sports performance technology company using health-grade ECG data and AI to deliver actionable physiological insight for athletes, practitioners, and teams. The platform focuses on understanding internal response to training – performance, recovery, and adaptation, rather than diagnostics or consumer wellness metrics.

The Opportunity

EXRT is not building another activity tracker or generic dashboard. The focus is on:

• Continuous ECG-derived insight
• AI-driven interpretation of physiological response (performance & recovery, not diagnostics)
• Decision-support for athletes, practitioners, and teams
• Integration with existing performance ecosystems rather than replacement

Commitment & Compensation (important)

This is an early-stage co-founder role.

• Cash compensation is limited at this stage
• Equity is meaningful and co-founder level
• Recent angel funding provides runway
• Further funding is actively planned following delivery of the next technical milestones

This role is suited to someone motivated by ownership, impact, and long-term value creation rather than short-term salary.

Technical Profile

You don’t need to cover everything, but strong experience in several of the following is expected:

• Backend engineering (Python preferred)
• Data engineering and time-series / biosignal processing (ECG experience highly advantageous)
• Applied ML / AI (classification, scoring, pattern detection)
• Cloud infrastructure (AWS, GCP, or Azure)
• API design and system architecture
• Experience working with complex, imperfect datasets

Experience in health-tech, sports-tech, or regulated environments is a plus, but not a requirement.

What\’s Offered

• Co-founder-level equity and long-term ownership
• Responsibility for technical strategy and execution
• Existing angel backing and active fundraising plans
• Direct collaboration with practitioners and end users shaping the product
