Jobbeschreibung

Job Details

• Location: Preferably in / near Vienna, or within a 2h time zone difference
• Languages: English (must) & German (nice to have)
• Experience: 8+ years (Strategic / System Level)
• Salary: 80K - 85K (If you're based in Vienna)
• Contract: All-in

Role and Responsibilities

• Drive the technical vision and architectural strategy for our backend services, writing and reviewing RFCs (Request for Comments) for major system changes
• Design complex, high-scale distributed systems using Golang, ensuring they are resilient, consistent, and observable by default
• Act as a "Force Multiplier" by building shared libraries, internal tools, and frameworks that make every other developer at fiskaly faster and safer
• Mentor Senior Engineers, helping them grow from "Service Owners" to "System Thinkers"
• Evaluate and implement new technologies (including AI coding agents and architectural analysis tools) to keep our tech stack modern and efficient
• Solve the hardest technical problems in the company—the ones that span multiple teams, involve complex race conditions, or require deep optimization of the Go runtime or database locks
• Bridge the gap between Product Strategy and Engineering Reality, helping leadership understand technical trade-offs and risk

What You Bring (Qualifications)

• Deep, battle-tested experience (8+ years) in Backend Engineering with a focus on System Architecture, and with previous Golang experience being a strong plus
• A track record of "Technical Leadership without Authority"—you can influence other engineers to follow your architectural advice through writing and persuasion, not just rank
• Experience designing systems that handle high throughput and high availability
• A pragmatic approach to AI: you understand how to use LLMs to simulate architectural stress tests, generate documentation from code, or automate migration scripts
• Experience with Event-Driven Architectures (Kafka/RabbitMQ) and understanding of eventual consistency pitfalls
• A history of improving developer experience—you hate bad tooling and fix it for everyone
• Excellent writing skills (English C1+). At the Staff level, the ability to write clear design docs is as important as your code
• Experience with cloud providers (GCP/AWS/Azure or similar) is a plus

What We Offer

• Influence: You will sit at the table where technical strategy is decided
• A culture that encourages you to use the latest tech and AI tools to accelerate coding
• 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 well-being and personal growth
