Who We Are

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

Our mission is simple: make receipts easy for everyone.

The Role

You are a Senior Backend Engineer with the mindset of a system architect. You will join a high-performing squad responsible for our API‑first SaaS solutions. Your work goes beyond writing code – you focus on complex distributed system problems, architecture, and reliability, while automating repetitive parts with AI coding assistants.

What You’ll Do

• Design and build resilient, high‑performance microservices in Golang, owning them from architecture to deployment.
• Use a Continuous Everything (GitOps) approach, deploying code multiple times a day with confidence via automated testing and monitoring pipelines.
• Leverage AI‑assisted development tools to accelerate boilerplate, unit tests, and documentation.
• Design and evolve our unified service interface, ensuring APIs are intuitive, strictly typed, and self‑documenting.
• Integrate AI/ML capabilities where they add value, such as anomaly detection in transaction logs or automated error classification.
• Maintain high‑quality documentation for internal teams and external developers, keeping it in sync with code.
• Mentor junior developers in Go, modern cloud practices, and AI‑augmented engineering.

What You Bring

• 5+ years of full‑time backend development experience, with a strong preference for Golang and deep understanding of OOP/SOLID principles.
• Mastery of distributed systems—knowledge of consistency models and fault‑tolerant architecture.
• “Force‑Multiplier” mindset: experience or strong interest in using AI tools to accelerate quality and velocity.
• Practical experience with Docker and Kubernetes; understanding of container lifecycle.
• Deep knowledge of RESTful and RPC‑based APIs; treat API design as a first‑class citizen.
• Familiarity with asynchronous messaging systems (RabbitMQ, Kafka, PubSub) and appropriate use cases.
• Experience with GCP (preferred) and modern database strategies (relational vs NoSQL).
• Clear communication skills for both technical and non‑technical stakeholders.

What We Offer

• A culture that encourages cutting‑edge technology adoption and AI tooling.
• A supportive environment that allows experimentation, safe failure, and continuous learning.
• Flexible working hours and a hybrid arrangement (Office in Vienna/Berlin/Madrid/Milan or Remote).
• Work permit sponsorship for qualified candidates.
• 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 culture that values well‑being and personal growth.
