As a UX/UI Designer at Mochi Health, your day-to-day work is fast-paced and deeply collaborative. You will be responsible for:

• Designing end-to-end user experiences for patient-facing web and mobile applications, focusing on onboarding, clinical tracking, and subscription management.
• Creating intuitive user interfaces for internal clinical tools, provider dashboards, and administrative portals to optimize healthcare delivery workflows.
• Collaborating daily with product managers, engineers, and clinical stakeholders to translate product requirements into high-fidelity wireframes, mockups, and interactive prototypes.
• Maintaining, scaling, and contributing to the internal design system in Figma, ensuring visual consistency across all digital touchpoints.
• Participating in rapid design reviews, incorporating feedback from leadership, and iterating on designs based on user testing and performance data.
• Working on-site at the San Francisco headquarters, participating in daily standups, and collaborating in real-time with cross-functional teams.

To be competitive for this position, candidates must demonstrate a strong balance of technical design mastery, analytical capability, and startup culture alignment.

• Experience Level – Typically requires 3 to 5+ years of professional experience as a UX/UI Designer, Product Designer, or similar role, preferably within a fast-paced startup or a consumer-facing healthcare company.
• Technical Mastery – Expert-level proficiency in Figma, including advanced prototyping, auto-layout, component libraries, and design system management.
• Analytical Mindset – Strong problem-solving skills, with the ability to pass basic quantitative screening questions and apply data-driven insights to design decisions.
• Communication Skills – Ability to articulate design decisions clearly and concisely to executive leadership, product managers, and engineering teams.

Must-have skills:

• A strong portfolio showcasing end-to-end product design work, high-fidelity UI design, and clear user flows.
• Experience designing for responsive web and mobile platforms.
• Comfort working in a high-intensity, structured in-office environment.

Nice-to-have skills:

• Experience conducting rapid, lightweight user research and usability testing.

Q: What is the typical work schedule and environment like for this role? A: The position is fully in-person at the San Francisco, CA office. The company operates on a structured, high-intensity schedule from 9:00 AM to 7:00 PM, Monday through Friday. This model is designed to foster rapid, real-time collaboration and fast product iterations.

Q: Why does a design interview loop include a math or probability question? A: The company values analytical reasoning and quantitative problem-solving across all roles. They use these questions during the initial screen to ensure designers can think logically, analyze product metrics, and approach complex user experience challenges systematically.

Q: How extensive is the take-home design challenge? A: The take-home challenge is a comprehensive exercise that typically requires designing multiple flows or a complete feature related to the product. Candidates are usually given a 3-day turnaround. It is highly recommended to set clear assumptions and focus on delivering polished, high-fidelity visual assets.

Q: How quickly does the hiring team make decisions between rounds? A: The process is designed to move very fast, sometimes concluding within a couple of weeks. However, because of the high volume of applicants, communication gaps can occasionally occur. Following up promptly after completing stages is highly recommended.

• Brush up on basic probability: Spend 15 minutes reviewing basic probability concepts (such as dice rolls, coin flips, and independent events) before your initial recruiter screen. Being able to solve these calmly and explain your logic out loud is a major differentiator.
• Document your assumptions clearly: When completing the take-home design challenge, you may receive brief or ambiguous instructions. Do not let this stall your progress. Create a dedicated slide or section in your presentation detailing the user, business, and technical assumptions you made to guide your design.
• Keep your presentations highly concise: When presenting your portfolio or design challenge to the hiring manager or executive team, focus on the core user problem, your design decisions, and the resulting impact. Keep your walkthroughs punchy and leave ample time for questions.

• Prepare for rapid scheduling changes: Because the company operates at a very fast startup pace, interviews may occasionally be rescheduled or adjusted on short notice. Maintain a flexible, adaptable attitude throughout the coordination process.
