Location: Jakarta, Indonesia

Job Type: Full-Time

Category: UX/Product Design - Developer Experience

Date Posted: August 10, 2026

Experience Level: Mid-Level (2-5 years)

Remote Status: On-site

🚀 Role Summary

• Lead product design initiatives for Xendit's developer-facing platforms, including the developer dashboard, API reference, and integration surfaces, focusing on enhancing the overall Developer Experience (DevEx).

• Translate complex technical requirements and user needs into intuitive, efficient, and trustworthy design solutions for a highly technical audience.

• Collaborate closely with Product Management, Engineering, and Content teams to ensure seamless integration of design elements, information architecture, and user flows.

• Spearhead user research and discovery efforts directly with developers to validate design assumptions and drive product improvements based on data-driven insights.

📝 Enhancement Note: This role is specifically focused on designing for developers, a niche within UX. The emphasis on "information-dense UI," "dashboards," "API reference," and "error states" highlights the need for a designer comfortable with complex technical interfaces, rather than typical consumer-facing applications. The "DevEx" specialization indicates a deep understanding of developer workflows and pain points.

📈 Primary Responsibilities

• Own the end-to-end product design process for the developer dashboard, ensuring clarity, speed, and trustworthiness in user interactions.

• Develop and refine information architecture for technical documentation and API references, working in close partnership with Engineering and Content teams.

• Design effective error states, empty states, and sandbox/testing flows to minimize developer friction and provide clear guidance when issues arise.

• Conduct user research and discovery sessions with developers to gather qualitative and quantitative feedback, informing design decisions and product strategy.

• Collaborate daily with the Developer Experience Product Manager and Engineering teams, acting as the primary design owner for developer-facing surfaces.

• Adopt and extend the existing domain design system, partnering with the senior design-system lead to ensure consistency and efficiency in design patterns.

• Champion a data-driven approach to design, ensuring all decisions are validated by user research and performance metrics.

📝 Enhancement Note: The responsibilities emphasize a hands-on approach to product design for a technical audience. The role requires not just visual design but also a strong understanding of information architecture, user flows within complex systems, and direct engagement with the target user group (developers). Partnership with engineering and adherence to a design system are key operational aspects.
