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 are launching a new venture in the FinTech space, and we're looking for a Co-Founder & Chief Technology Officer (CTO) to lead product strategy and development from day one. This is a unique opportunity to co-build a company with us from the ground up, backed by the resources, expertise, and network of Antai Ventures.

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 FinTech or similar regulated markets and building AI-first digital products.
  • What We Offer

  • A unique opportunity to co-found a startup with a de-risked path and the backing of a successful venture studio.
  • Access to Antai’s full operator team across Product, Engineering, Design, Legal, Talent, GTM, Fundraising, and more.
  • Strong equity stake in the company and the opportunity to get equity in other start-ups in our portfolio.
  • Being part of Antai’s ecosystem of serial entrepreneurs and top-tier investors.
  • Office space in Barcelona, Madrid, and Mexico City.
  • Ready to Build?
