Sezzle is looking for a UX Designer focused on Platform Experience to design scalable user experiences across our entire ecosystem, including hardware, software, APIs, and internal tools. This role sits at the intersection of product, engineering, operations, and safety, designing the systems that power our platform end-to-end.

What You'll Do

Design user experiences that span hardware, software, APIs, and operational workflows.
Translate complex technical systems into intuitive, usable interfaces.
Map end-to-end platform journeys across multiple user types (operators, engineers, customers, internal teams).
Design configuration flows, monitoring dashboards, alert systems, and control interfaces.
Design for high-stakes environments where usability impacts safety and performance.
Partner closely with Product, Firmware, Software, Hardware, and Operations teams.
Participate in technical discussions and translate constraints into thoughtful UX solutions.
Contribute to or build scalable design systems for platform components.
Conduct user research with operators, engineers, and customers.
Rapidly prototype and test complex flows.

What We're Looking For

4+ years of UX or Product Design experience.
Experience designing platform tools, enterprise software, technical dashboards, or complex systems.
Strong systems thinking — able to design beyond single screens.
Experience working in cross-functional technical environments.
Comfort reading technical documentation or collaborating deeply with engineering.

Nice to Have

Experience in robotics, hardware-enabled products, mobility, IoT, or industrial systems.
Experience designing for operational tools or safety-critical workflows.
