Job description

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.

• Conduct user interviews, usability tests, and competitor analyses to inform design decisions
• Maintain and evolve Neptune's design system, ensuring consistency across the platform

• Advocate for the end user throughout the product development lifecycle

Your profile

Minimum Qualifications

• 5+ years of experience in product design or UI/UX design, ideally in a B2B or enterprise software environment
• Strong portfolio demonstrating end-to-end product design work across web or desktop applications
