#136008 - 产品设计师 - 身份验证与账户安全

We are seeking a hands-on Product Designer to create and ship authentication, account-management, and account-security experiences across web and mobile surfaces. This role owns small-to-mid scoped initiatives from problem framing and exploration through validation, engineering-ready specifications, implementation quality assurance, and launch, while partnering with senior designers on larger efforts.
Enterprise experience strongly preferred.

• Own end-to-end product design for defined authentication and account-management initiatives.
• Frame problems, explore concepts, iterate with partners, and deliver engineering-ready specifications.
• Audit and map current sign-up, sign-in, routing, account, and security-settings experiences.
• Identify inconsistencies and seams across related identity and account flows.
• Design complex, multi-path experiences that respond to user and account conditions.
• Produce rapid MVP explorations for experimental work.
• Deliver responsive web and mobile-web designs with complete empty, loading, error, edge-case, and recovery states.
• Create redlines, interaction details, and clear implementation documentation for engineering.
• Conduct lightweight usability validation and draft interface copy for content review.
• Provide design quality assurance through implementation and launch.
• Participate in engineering scoping and refinement, reasoning about authentication, verification, session states, routing logic, and system dependencies.
• Work within an established design system and extend it responsibly when new patterns are needed.

Must-Have Skills
· A portfolio demonstrating strong product and visual design craft, including end-to-end web and mobile application flows. Applications without a portfolio will be considered incomplete.
· Product-design experience shipping production software, ideally involving account, onboarding, or other flow-based product experiences.
· Experience designing, shipping, and iterating in close partnership with product management and engineering.
· Proven ability to design complex, multi-path flows that branch according to user or account conditions.
· Thoughtful handling of edge cases, error and recovery states, accessibility, and user control across connected surfaces.
· Strong UX principles and the ability to translate business and technical requirements into clear design direction.
· Experience working within and responsibly extending an established design system.
· Mastery of Figma, solid prototyping skills, and experience producing clear engineering-handoff documentation.
· Clear communication and a collaborative, low-ego approach to cross-functional work.
· Balanced strength in systems thinking and visual execution.
· Technical literacy to reason directly with engineers about authentication flows, verification and session states, routing logic, system dependencies, and error handling. Coding is not required.
· 3-5 years of UX design experience. Portfolio evidence and case-study depth matter more than tenure; candidates must show shipped, engineering-implemented work on complex multi-path flows and the ability to operate independently on defined initiatives.
Nice-to-Have Skills
· Experience with authentication, identity, account security, or other trust-related product experiences.
· Experience designing sign-up, sign-in, onboarding, settings, or preferences interfaces.
· A data-informed approach using research, experimentation, and product metrics.
· Experience running lightweight usability testing and drafting interface copy with research and content partners.
· Experience designing for international audiences or regulated requirements.
· A portfolio case study showing an authentication, verification, or account-lifecycle flow redesigned end to end with measurable friction or conversion outcomes, or comparable workflow mapping and systems reasoning.
· Prior contractor experience with a record of quickly learning complex product areas and operating independently.
· Experience identifying inconsistencies across identity or account surfaces and driving cross-flow alignment.
· Thoughtful use of AI for exploration, prototyping, research synthesis, or documentation while preserving human judgment.
· A bias toward operationally useful artifacts that engineers can build from.
Required Tools & Platforms
· Figma.
· An established or enterprise-scale design system.
· Prototyping and engineering-handoff workflows.
· Jira, Confluence, Slack, or equivalent collaboration tools.
Location, Time & Engagement
· Candidates must be based in the United States.
· US Central Time working-hour coverage is required.
· This is a remote contract engagement at 40 hours per week.
· The anticipated engagement runs through March 31, 2027.
· This is not currently a contract-to-hire opportunity.
