Software Engineer (Agentic) Full Remote · European Timezone · Professional English Required About the Role We're looking for a Software Engineer with an Agentic mindset — someone who doesn't just write code, but builds systems that think, act, and adapt. You'll work on a production AdTech platform with real business impact, and you'll increasingly work alongside AI agents and design agentic workflows as part of your daily engineering practice. This is not a ticket-execution role. We expect you to bring judgment, ask the hard questions, design thoughtfully, and genuinely care about the quality of what you ship — whether that code was written by you, assisted by AI, or executed autonomously by an agent you designed. Responsibilities - Design, develop, and maintain robust, scalable backend services following Domain-Driven Design (DDD) principles. - Take full technical ownership of features — from design through deployment and monitoring. - Build and orchestrate agentic workflows: autonomous pipelines where AI models (Claude, LLMs) take actions, call tools,



and solve tasks with minimal human intervention. - Actively participate in architecture decisions with strong analytical thinking and technical depth. - Ensure code quality through SDD, TDD, and BDD methodologies, with sharp attention to detail. - Collaborate on code reviews, refinements, and technical planning. - Proactively identify and address technical debt, performance bottlenecks, and security risks (OWASP, SOLID). - Build and maintain CI/CD pipelines across Bitbucket, GitLab, or GitHub. - Produce well-reasoned technical designs before writing the first line of code.
