CTO & Co-Founder - EdTech AI
🌍 About Antai Ventures
Antai Ventures is a leading venture studio headquartered in Barcelona, with a strong presence across Southern Europe and Latin America. We team up with exceptional entrepreneurs to build disruptive, scalable companies from scratch. Since 2012, we've co-founded 30+ ventures, including Glovo, Wallapop, PlatanoMelon, and PiperAI. Collectively, our startups have raised over $1.5B in funding, generated $3B+ in shareholder value, and created 5,000+ jobs.
💡 The Opportunity
We’re building Selvia, an AI-powered EdTech platform revolutionizing how people prepare for official exams — and we’re looking for a Co-Founder & Chief Technology Officer (CTO) to lead Product and Tech from day one.
Selvia combines educational science, data, and adaptive learning to create hyper-personalized study experiences. By understanding each student’s personality, learning style, and lifestyle, it builds customized study plans, simulations, and resources that maximize the return on study time — much like having a private tutor for everyone.
We’re starting with a massive challenge — competitive exam preparation — but our long-term vision is to become the lifelong learning companion for millions, supporting both personal and professional growth. We already have a live MVP with paying customers, validating our hypothesis and giving very positive signs of early traction.
You’ll join Anna Vique, Selvia’s CEO and co-founder, who brings over a decade of strategic and leadership experience as CRO at CTAIMA (where she led international expansion into 3 LatAm markets in under a year) and as Senior Manager at Accenture Strategy.
This is a unique opportunity to co-build a company from the ground up, backed by Antai’s resources, expertise, and operational network.
🛠️ What You’ll Do
Collaborate with the co-founders and executive team to define the product’s technical vision and roadmap, ensuring alignment with business strategy.
Build and lead a world-class engineering team across backend, frontend, and data—fostering a cloud-native, continuous delivery mindset and ensuring professional growth.
Architect a scalable, resilient, and secure technology platform with freedom to choose between monolith, microservices, serverless, and other modern patterns.
Select the right technology stack for both backend and frontend applications, optimizing for speed, reliability, and scalability.
Lead development with strong knowledge of software design principles, particularly Domain-Driven Design (DDD) and SOLID principles.
Oversee the design and deployment of a robust data processing pipeline, managing ingestion, transformation, and storage for high-volume use cases.
Champion engineering excellence, continuous improvement, and agile methodologies across the product lifecycle.
Act as a tech-business bridge, communicating complex ideas clearly to non-technical stakeholders and collaborating closely with the CEO and executive team.
Foster a culture of curiosity, ownership, and proactive problem-solving across the tech team.
🔍 What We’re Looking For
8+ years of experience as a Software Engineer, ideally in backend technologies (Java/Spring or PHP/Symfony preferred).
Proven leadership experience as a Tech Lead or CTO in a startup or fast-growing digital company.
Strong grasp of Cloud Native environments: Docker, Kubernetes, microservices, service mesh, infrastructure-as-code.
Expertise in designing and scaling data architectures, including pipelines for stream/batch processing and data warehousing.
Deep understanding of software architecture, testing, design patterns, and team workflows in agile development environments.
Track record of hiring, mentoring, and scaling high-performing engineering teams.
Entrepreneurial mindset and hands-on, get-it-done approach.
Excellent communication and interpersonal skills—able to translate tech into business.
Fluency in both English and Spanish.
Bonus: Experience in EdTech or similar consumer products and building AI-first digital products.
🤝 What We Offer
The chance to co-found a company with Antai Ventures, one of Europe’s leading venture studios, with a proven model for turning bold ideas into successful businesses.
A founder-first structure — Founders keep majority ownership and control of the company, with Antai as a Founding Partner and Board Member.
Initial funding and hands-on support from Antai’s in-house operator team across Product, Tech, Design, Growth, Legal, Talent, Fundraising, and Finance — so you can focus on building, testing, and scaling.
Access to Antai’s ecosystem of serial entrepreneurs, mentors, and top-tier investors.
The opportunity to earn equity in Antai’s wider portfolio as part of our founder network.
