Do you want to rethink how building projects are planned – not from the sidelines, but right at the heart of it?
At vyzn, we’re shaping the future of construction planning with a data- and AI-driven SaaS platform. 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 Lead Developer (80–100%), you’ll be part of a team that doesn’t just think big, but also makes things happen. If you’re motivated to help shape an ambitious ETH spin-off that combines sustainability and AI, then you’re exactly who we’re looking for.
Tasks
You’ll take ownership of our technical foundation and guide a small but highly skilled development team (3–6 people). You’ll combine hands-on full-stack coding with technical leadership, ensuring that our platform remains scalable, robust, and future-ready as we expand into new markets.
* Lead the technical development of our SaaS platform - from concept to deployment
* Shape and evolve the software architecture to ensure scalability, performance, and maintainability
* Mentor the development team, 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
* Preferably based in Switzerland or Germany (hybrid or remote with occasional workshops), or in Egypt, where part of our engineering team works (remote-friendly, on-site workshops with the Egypt team).
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: Learn every day and develop both professionally and personally through challenging development tasks.
* A-Player Team: Collaborate with passionate doers who drive impact and innovation forward.
* Impact: Contribute to a more sustainable, livable future with solutions that benefit both people and the planet.
* Direct Collaboration: Work closely with the founding team and actively shape key projects.
* 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.
