Lead Full Stack Engineer (Sofia, BG)

This is your chance to lead the charge in building high-impact, enterprise-grade applications that scale - fast. We're looking for a hands-on technical leader who thrives in the full-stack world of Java (Spring Boot) and Angular, and can drive a modern, cloud-native architecture using microservices, containerization, and DevOps automation. From designing robust APIs to embedding AI-assisted development, this role is built for someone who can think strategically and code tactically.

You won’t just be building apps , you'll be shaping how custom software is delivered across the organisation. This means championing full continuous delivery in the cloud, driving performance, security, and observability standards, and leading by example in test-driven development and CI/CD best practices. You'll mentor developers, influence architectural direction, and help define a culture of technical excellence that accelerates innovation and scales with the business.
