We at Holycode are currently looking for a Full Stack (JavaScript + Python/Go/Rust) Engineer with strong skills and proven experience to join our Scalera AI team here in our Belgrade office.
Scalera AI is an ETH spinout that develops an AI-powered SaaS platform designed to automate tendering and supplier selection in the construction industry. The company has already processed more than CHF 3 billion in tender volume and has secured strong traction in Switzerland and Austria. With a clear vision to reduce 30-40% of material costs per project, the team of twenty people (composed of research-driven engineers from ETH and EPFL) works from the Zurich headquarters in a dynamic and fast-paced startup environment.

What you’ll need:
- Over 4 years of experience working with React, Next.js, and TypeScript, as well as the knowledge of Python and FastAPI on the backend.
- Previous exposure to SaaS product development is highly valuable, while familiarity with AI tools such as Lovable, Cursor, or Claude would be an advantage.
- You should thrive in fast-moving environments, bring a strong problem-solving mindset, and enjoy contributing across the stack.
- A startup mentality, curiosity, and the ability to interact directly with users and customers are essential qualities for success in this role.
- You are fluent in English.
