CTO & Co-founder Maia Care

Backed by GCO Ventures and Byld, we are building Maia Care, a digital platform aiming to transform how millions of women experience menopause.

Maia brings together science, human support, and technology to offer personalized plans, access to certified professionals, and a safe, warm, and scalable digital experience. Our goal is to help every woman navigate this stage with clarity, support, and confidence, through an evidence-based proposition, personalization, and continuous accompaniment.

We have strong early validation, active acquisition campaigns, a first product version that is evolving, and the momentum of two experienced venture builders who actively support the vision and growth of the project. After the CEO joined, the next step is to strengthen the core team with someone who can turn the product and technology vision into a robust, distinctive platform built to scale.

We are looking for an entrepreneurial, strategic, and deeply hands-on person to lead Maia’s technology as CTO. You will be responsible for defining the architecture, making key stack and infrastructure decisions, bringing AI in pragmatically, and building the technical foundation on which Maia will grow over the coming years.

• Demonstrated ability to build digital products from early stages, ideally in startups, scaleups, or 0→1 environments.

• Experience or practical judgment in using AI applied to product, automation, personalization, agents, models, or developer tools.

• Hands-on mindset: comfort going deep into technical detail, coding, reviewing solutions, or unblocking problems when needed.

• Ability to work very closely with business and product, translating strategic goals into clear technical decisions.

• Judgment to decide when to build, buy, integrate, or lean on external partners.

• Sensitivity to security, privacy, data protection, and responsible handling of sensitive information.
