Senior IT Business Analyst (f/m/d)

Your mission

JTL is one of the leading providers of e-commerce software in the German-speaking region — with around 450 employees across the group and more than 50,000 customers across a wide range of industries. We develop scalable, flexible solutions for the online retail of the future, from ERP systems to shop and marketplace integrations.
You'll join our IT team as the bridge between the business and engineering. We translate what the business needs into things our IT team can actually build — and we push back when something doesn't add up technically. You'll thrive here if you enjoy getting into how systems really work and bringing people into alignment without leaning on a title to do it.

About the role

This role sits in IT — not in a business department. You bring genuine IT engineering knowledge into the conversation with the business: a real understanding of how systems work, how architectures and data flows are structured, and what the technical consequences of a requirement actually are.
That foundation is what makes the role work. It lets you challenge both what the business is asking for and what the IT team proposes as a solution — and assess feasibility yourself instead of routing every question to engineering.
Delivery ownership and SLA accountability sit with the IT Manager / IT Leiter. Your job is to make sure that on the way there, the right things get built — grounded in business need and technically sound.

Your responsibilities

• Capture requirements from business stakeholders, challenge them technically, and turn them into clear specs, epics, and acceptance criteria with real technical depth
• Assess feasibility and technical impact yourself — without looping in engineering for every question
• Structure and prioritize the functional backlog, and bring requirements to a clear, testable, build-ready state
• Drive adoption of what ships: spot change impact early, create clear rollout materials, and gather feedback to fine-tune
• Prepare business cases and option comparisons that ground decisions in business value, technical effort, and risk

Your profile

• You have a background in IT engineering, software development, or technical systems — and you've worked closely with business stakeholders
• You understand APIs, data flows, system architecture, and integration patterns well enough to judge technical proposals on your own
• You know your way around Microsoft 365 in a hybrid setup (cloud + on-premise) — including administration and configuration, not just using it
• You bring proven requirements engineering practice: epics, user stories, and acceptance criteria
• You manage stakeholders well even without formal authority, and you frame decisions using data and metrics
• You have a working knowledge of IT security and compliance basics
• You're fluent in German and English, written and spoken

Nice to have

• SQL or data querying skills for independent analysis
• Experience evaluating or selecting SaaS tools and IT solutions
• Comfortable using AI tools to support data-driven decisions
• Experience with agile ways of working (Scrum, Kanban)
• Scripting or automation skills (e.g., Power Automate, Python)
