🚀 Who We Are

Millions of people interact with fiskaly every day, even if they don’t realize it. 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.
