Engineering Lead, Full Stack Developer, Software Engineer

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 an 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.

• 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 Type Script 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.

• 5+ years of experience in software development, ideally in SaaS, data, or AI-driven platforms.
• Strong skills in Type Script/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).

• 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.

• 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.
