User Experience User Interface Design Jobs in Santa Rosa, CA

HiJenny is the AI assistant homeowners have always needed. We help people manage everything about their home, from keeping track of what they own to scheduling and managing services to navigating renovations without the fear, chaos, and budget surprises that have plagued the industry for decades.

Your home is likely your biggest asset, yet most homeowners have no real system for managing it. HiJenny changes that. She maintains your home inventory, coordinates services, connects you with vetted contractors, and keeps every project, big or small, on track and on budget. She works for you, not the contractor, not the platform.

Led by repeat founders and backed by top investors including HF0 Residency, Long Journey Ventures, MSAD, Walter Ventures and StoryHouse, HiJenny is building the home operating system that every homeowner deserves.

HiJenny is looking for a Senior UI/UX Designer with deep consumer mobile and web expertise,  someone who obsesses over interaction design, visual craft, and the small details that make an app feel effortless on iOS, Android, and the web.

This is a high-impact role at the intersection of design craft and product thinking. You'll own end-to-end design across three interconnected pillars: helping homeowners build and maintain a living inventory of their home, seamlessly scheduling and tracking services, and managing projects from first quote to final walkthrough, with full visibility into cost, timeline, and progress.

You'll bring clarity to complexity, making something that touches permits, invoices, contractors, appliances, and maintenance schedules feel like second nature to everyday consumers. You'll design with the conventions of iOS and Android in mind, know when to break them, and apply that same instinct to responsive web.

This is a rare opportunity to work on a product with genuine emotional stakes: people's homes, their savings, and their peace of mind.

UI/UX Design Leadership

• Own the design vision and execution for the full homeowner experience across all three core pillars: home inventory, services, and projects, ensuring each feels cohesive, intuitive, and distinctly HiJenny across iOS, Android, and responsive web.
• Define information architecture, interaction models, and visual design systems that work beautifully across platforms, including the micro-interactions and motion design that give consumer apps their feel.

Consumer-Centered Design

• Translate complex end-user workflows into experiences that feel simple, trustworthy, and genuinely useful.
• Design and optimize onboarding flows that activate new users quickly, and retention surfaces that keep them engaged over time.
• Apply iOS Human Interface Guidelines and Material Design principles fluently, knowing when platform conventions serve the user and when HiJenny's experience should diverge from them.

Design Systems & Crafts

• Build and maintain a scalable design system, including component libraries, design tokens, motion guidelines, and handoff specs, that works across mobile-first and responsive web contexts.
• Champion accessibility from the start: WCAG compliance, dynamic type support, color contrast, and screen reader compatibility are part of your design process, not an afterthought.

Research & Insights

• Lead user research initiatives: interviews, usability tests, prototype testing, and in-app behavioral analysis to generate insights that sharpen each product pillar.
• You're as curious about why a homeowner forgets to log a service as you are about why they abandon a contractor bid.

Cross-Functional Collaboration: 

• Partner daily with the product team and engineering teams to ship high-quality features on schedule. 
• Present design decisions and rationale clearly to founders, product, and engineering. Advocate for the end-users when business pressure is high, and trade-offs need to be made.

Metrics & Iteration

• Define and track experience quality metrics: task completion, drop-off, CSAT, activation, retention across each product surface. Use data to iterate relentlessly on what's shipped and inform what's next.

Stakeholder Communication

• Present design decisions and rationale clearly to founders, product, and engineering. Advocate for the homeowner when business pressure is high and trade-offs need to be made.

• 8+ years of UX/UI design experience, with at least 3+ years focused on B2C consumer mobile and web products (degree in Design, HCI, or equivalent experience).
• A strong portfolio demonstrating end-to-end design work across iOS, Android, and responsive web, including evidence of visual design craft, not just wireframes. Please include in your application.
• Shipped consumer apps on both iOS and Android. You understand mobile-native patterns, gesture navigation, bottom sheets, tab bars, haptic feedback, and know when to apply them.
• Deep proficiency in Figma: component libraries, auto layout, variables/tokens, prototyping, and developer handoff. Experience maintaining design systems at scale.
• Strong user research skills: you know how to ask the right questions and synthesize findings into clear design direction.
• Data literacy: comfortable reading analytics dashboards and connecting design decisions to measurable outcomes.
• Working knowledge of accessibility standards: WCAG guidelines, dynamic type, color contrast, and screen reader behavior on iOS and Android.
• Comfortable working with distributed, cross-timezone teams.
• Experience in consumer lifestyle, home services, productivity, marketplace, or fintech apps is a strong plus. If you've designed for high-trust, high-stakes consumer moments, we want to hear about it.

• You've thought hard about how to make a complex, high-stakes experience feel approachable to someone who just wants their dishwasher fixed, and you've shipped that thinking.
• You're as comfortable presenting to founders and leadership as you are pairing with engineers in a Figma handoff.
• You bring strong opinions, loosely held. You can defend your choices and change your mind gracefully.
• You thrive in ambiguity and can move fast without sacrificing craft.
• You're energized by working on something with real emotional stakes for real people.
• If based in the Bay Area, you're excited to be in-person with the team regularly. If remote, you're a strong async communicator who keeps collaboration tight across time zones.

We're a small, focused team that moves fast and cares about quality. You'll have meaningful ownership from day one, direct access to founders, and the chance to define design culture at a company that's still early enough for your decisions to matter for years.

We offer competitive compensation, flexible work arrangements, and a mission that makes you want to open your laptop in the morning.

HiJenny is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
