We at Holycode are currently looking for a Full Stack (React/Python) 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.

Joining Scalera AI means becoming part of a highly collaborative and research-driven team that is shaping a product with significant impact in the construction industry. You will have the opportunity to work on a platform that is scaling rapidly and to influence its direction from an early stage.

About the Role:

The position is designed to strengthen Scalera’s frontend capabilities within a backend-heavy engineering team. Around 70% of the work will focus on frontend development while the remaining 30% will involve backend contributions.
You will work closely with the CEO, CTO, and Head of Engineering and use a modern stack that includes React, Next.js, TypeScript, Python with FastAPI, and Google Cloud Platform.

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.

Benefits:

Private health insurance
Flexible work model – full remote or hybrid
Equipment of your choice (laptop, monitor, accessories)
High-growth company with innovative products
