Product development:
Lead the development of the MVP, ensuring timely delivery of core features that address user needs.
Oversee the full-stack development, from front-end to back-end, ensuring a seamless and efficient product experience.
Integrate AI-powered features, such as chatbots, personalised mental health recommendations, and data analysis tools.
AI/ML implementation:
Lead the AI/ML development efforts, selecting the right tools and technologies for the product.
Oversee the training and integration of AI models, ensuring the algorithms are personalised, ethical, and effective for users.
Continuously monitor and improve AI performance, leveraging data insights to optimise user experience.
Mobile App development:
Oversee the development of the mobile app (iOS/Android), ensuring it’s optimised for user experience and functionality.
Ensure the app is scalable and able to handle increased traffic as the user base grows.
DevOps & infrastructure:
Manage the app’s infrastructure, including hosting, security, and data storage, ensuring high availability, scalability, and compliance.
Set up and manage CI/CD pipelines, and ensure automated testing and deployment processes.
Collaboration & stakeholder management:

Ensure the app complies with relevant health data regulations (e.g., HIPAA, GDPR) and best practices in user data security and privacy.
Oversee ethical considerations for AI models, ensuring they are transparent, non-biased, and sensitive to mental health contexts.
Experience
5+ years in technical leadership roles (e.g. CTO, Head of Engineering) at a startup or growth-stage tech company.
Strong hands-on experience in full-stack software development, AI/ML technologies, and mobile app development.
Proven track record of delivering scalable, secure, and high-performance software products.
Experience in building or scaling consumer-facing mobile applications (iOS/Android).
