Do you want to build the core platform that enables early-stage building design to be optimized through simulation and AI?

At vyzn, an ETH spin-off, we’re building a data- and AI-driven SaaS platform that shapes the future of construction planning. In just a few clicks, developers, planners, and architects receive precise insights on emissions, energy, comfort, and costs - based on automatically refined 3D building models - along with AI-powered recommendations to support well-informed decisions.

As a Engineering Lead (80–100%), you’ll take ownership of the technical foundation of our platform and lead a small, high-caliber engineering team (3–6 people), with the opportunity to expand and shape the team as we grow. You’ll be deeply hands-on in the codebase while shaping architecture, scaling systems, and helping steer how our product evolves. You enjoy balancing speed, pragmatism, and engineering quality. This role includes significant technical ownership and long-term upside through our ESOP program.

Tasks

• Lead the technical development of our SaaS platform - from concept to deployment. Our stack is a modern Angular frontend paired with a scalable Nx-powered NestJS microservices backend, running on TypeScript end-to-end, with MySQL, Redis/BullMQ for async workloads, and fully containerized via Docker.
• Shape and evolve the software architecture to ensure scalability, performance, and maintainability as we grow the company and enter new markets.
• Build and inspire a world-class engineering culture. Mentor the development team (3–6 developers), fostering clean code, knowledge sharing, and best practices
• Collaborate closely with product and design to translate user needs into technical solutions
• Coordinate technical priorities with the CTO and founders
• Oversee code reviews, testing, and deployment pipelines

Requirements

• 5+ years of experience in software development, ideally in SaaS, data, or AI-driven platforms
• Strong skills in TypeScript/Angular, Node.js, and cloud-based architectures (Azure or AWS)
• Proven experience in leading small engineering teams or mentoring developers
• A structured, pragmatic mindset — you know when to build fast and when to build for the long term
• Excellent communication skills in English; German is a plus
• Based in Europe (hybrid or remote with occasional workshops)

Bonus

• Interest in architecture, BIM, and sustainability in the built environment
• Several members of our tech team are based in Egypt. Experience collaborating with teams across the MENA region, or familiarity with the culture is a plus

Benefits

• Flexibility: Hybrid and remote work options to fit your lifestyle.
• Growth: Work on ambitious technical challenges that accelerate your professional and personal growth as we roll-out our platform in new markets.
• A-Player Team: Work alongside researchers, founders, and industry experts.
• Impact: Redefine how buildings are planned and optimized, enabling a more sustainable, affordable and livable future
• Builder Culture: High autonomy, low bureaucracy, fast decisions.
• Innovation at the Intersection of AI and Construction: Be part of groundbreaking platform innovation that combines cutting-edge technology with sustainable building solutions.
• Long-Term Potential: Join a dynamic, growing startup with flat hierarchies, high ownership, and the opportunity for long-term collaboration, including participation in our ESOP program.
