Senior Software Engineer - Algorithms

All3 is transforming how buildings are conceived, developed, and delivered. We combine AI-powered design with robotic prefabrication and on-site assembly to build custom architecture at the cost and speed of mass production - unlocking even the most complex sites.

We’re currently seeking a Software Engineer to design and implement distributed systems that power our construction platform. You’ll work at the intersection of software engineering and structural design - building tools that connect computational logic with real-world construction data and enable automation at scale.

• Develop services for automating structural calculations and model generation;
• Work side to side with structural engineers to integrate domain knowledge into software solutions;
• Deep dive into construction requirements, standards, building physics, and much more;
• Create optimization algorithms and validating hypotheses on real construction data;
• Enhance system infrastructure, including optimisation for performance and scalability;

• Strong knowledge of Python;
• Solid understanding of algorithms and data structures;
• Experience with frontend technologies (JavaScript, TypeScript, React) is a plus;
• Interest or experience in construction engineering domains (structural mechanics, FEA, BIM);
• Analytical mindset and ability to work autonomously on complex, open-ended problems.

• Chance to be a part of a large-scale project;
• Team driven by impactful cause;
• Hybrid format of work with spacious office in New Belgrade;
• Private health insurance including dental;
• Language courses;
• Flexible working schedule;
• 20 days of annual leave.
