As a B2B company, we power the retail technology behind digital receipts and secure, legally compliant transactions. By making receipts tamper-proof through digital signatures, we help fight tax fraud. And with our paperless receipt solution, we offer consumers a modern alternative while helping merchants streamline their operations. Sure, our solutions sound complex but our mission is simple: make receipts easy for everyone . 🎯 The Role In this role, you aren’t just a "Senior Dev." You are an Agentic Architect . You will design the frameworks that allow AI agents to write, test, and deploy our microservices. The 90/10 Rule: We want you to spend 90% of your time designing the agents, the prompts, the feedback loops, and the system architecture. You should only be "hands-on-keyboard" for the final 10%, the precision tuning, the complex edge cases, and the creative perfection that AI cannot reach. 🛠️ What You’ll Do Agentic Orchestration: Design and implement multi-agent workflows to automate the full software development lifecycle. Build the "Machine": Create autonomous systems that take high-level requirements and output production-ready applications. Architect for Autonomy: Design system boundaries, clear separation of concerns, well designed API interfaces and find ways to provide context to agents. Reliability Engineering: Implement robust verification loops. You will build the "Judge" agents that audit the "Coder" agents to ensure our fiscal signatures remain tamper-proof and legally compliant. Human-in-the-Loop Design: Define the touchpoints where human expertise is most impactful, ensuring our transition to agentic engineering is seamless and safe. ✨ What You Bring The "Force-Multiplier" Mindset: You find writing boilerplate physically painful. You have a proven track record of using AI to do the work of five engineers. Golang Mastery (5+ Years): You know Go well enough to know exactly when an agent has produced "hallucinated garbage" vs. "idiomatic excellence." Systems Thinking: Deep experience in modern system architecture and API design. You understand how to manage service communication and wrap AI agents securely around complex infrastructure. Agentic Experience: You have experimented with or deployed multi-agent setups. You understand the difference between a simple "prompt" and a "recursive autonomous loop." Quality Focus: You know how an architecture or design will evolve and plan for evolvability. You write code that is readable and well maintainable without needing a single code comment. 💡 What We Offer A culture that encourages you to use the latest tech. If an AI tool helps you code 20% faster, we want you to use it A supportive environment where you can try new things, fail safely, and learn constantly Flexible working hours and a hybrid work arrangement (Office in Vienna/Berlin/Madrid/Milan or Remote) Work permit sponsorship for qualified candidates A dedicated budget for personal and professional development and regular 1:1 career planning Company hardware of your choice (Windows, Linux, or Mac) A vibrant, inclusive company culture that values your well-being and personal growth 💡 Why fiskaly Joining fiskaly means contributing to a mission-driven company that is redefining how compliance is done in Europe and beyond.
