At Stackgini we are building the AI operating system for Autonomous Enterprise IT. IT landscapes of large enterprises have never been under more pressure. Thousands of applications to govern. Major transformations to manage. Growing regulatory complexity on one side, business units shipping AI prototypes in days on the other. And in the middle: enterprise IT teams still managing and collecting tech demands manually, managing the complexity of highly integrated processes and systems. Stackgini changes this fundamentally.
Stackgini's system understands its customers' enterprise tech landscape from the ground up, from technical configuration to application documentation, from individual IT demands to dependencies across the entire tech portfolio, with the depth of knowledge of a senior IT expert and the speed of a machine. Some of the largest organizations in this world trust Stackgini including DAX-40 and Fortune-500 customers like Siemens Healthineers or REWE. We're a small, talent-dense team of >10, building what we believe will change how the world's largest companies operate.
A Product Engineer at Stackgini owns features end to end. You take a customer problem, scope it with Product & CSM, design the solution, build it across the stack, ship it, and stay close to it after release. You are close to users. You join customer calls, run user tests, read support context, and you use that input to decide what should exist and how it should behave.
AI is core to our product, but we don't run agents for everything. We use them where they create real value. For that we built our own LLM harness from hard-earned production experience: maximum freedom for the model, without compromising on enterprise control, governance or EU data residency. If you are obsessed with how AI systems behave, fail and improve, this is the place for you.
Small teams of 2 to 3 engineers around a topic. We deploy continuously to production. We use AI tools heavily, and you have freedom in which ones (e.g. Cursor, Claude, Codex). The engineer who ships a change owns it in production. If something breaks, you lead the fix.
We work from our office in Berlin (hybrid, but most engineering happens in-person).
