Senior Product Designer

Senior Product Designer
About the Job
Neptune Software is the AI execution layer for SAP. Enterprises are moving from software that records, to software that acts — AI agents running routine work while people govern the exceptions. What stands in the way isn't the models; it's that the logic agents need to act on is locked inside SAP.
Neptune runs inside the customer's own landscape and makes that logic executable by AI: agent-ready context, governed tools, and applications where agents act under the customer's own authorizations, with guardrails enforced by the platform — not by the prompt.
With Naia, our AI layer, teams build from natural language and deploy agents on ECC today that carry to S/4HANA unchanged, always at Clean Core. SAP-certified, 500+ enterprises, fifteen years in production: we are where core business systems learn to act.
As a Senior Product Designer at Neptune Software, you will play a central role in shaping the user experience of the Neptune DX Platform - the tool trusted by enterprises worldwide to build powerful business applications. You'll bridge the gap between complex technical capabilities and intuitive, elegant interfaces, working hand-in-hand with product managers and engineers to craft experiences that genuinely delight our customers. This is a hands-on role: you will be in the design files and in the code, building working prototypes yourself rather than handing off static specs.
