Design Engineer

InstaLILY AI builds vertical AI Teammates (InstaWorkers™)—autonomous, role-based AI workers that execute revenue-critical work end-to-end inside a company's existing systems. Coordinated by InstaBrain™, our shared company intelligence layer, InstaLILY transforms fragmented data, inboxes, ERPs, and CRMs into reliable execution.

Design engineers bring “taste” into engineering. They ship high-craft UI while building the systems, tooling, and workflows that help teams move faster and build better products in an AI-native environment. At InstaLILY, design engineers own production UI quality, design systems as infrastructure, and prototyping workflows that turn emerging ideas into shipped experiences.

Shape AI-native product experiences

• Design and build customer-facing experiences across chat, voice, copilots, and agentic workflows.
• Turn concepts, prototypes, and product ideas into polished, production-ready interfaces.
• Bring strong front-end craft to interaction design, responsiveness, and implementation detail.

Build design systems as infrastructure

• Build and evolve a design system in code as shared product infrastructure, across core components, tokens, patterns, and documentation.
• Help make the system machine-consumable, so both humans and AI-assisted tools can generate consistent interfaces from shared foundations.

Bring taste to what ships

• Bring strong judgment to UI craft and implementation quality, making thoughtful decisions around interaction design, accessibility, performance, and maintainability.
• Help ensure what ships feels clear, cohesive, and intentional, with the discernment to refine details, uphold standards, and know what elevates the product experience.

Improve tooling and team workflows

• Build internal tools that support teams across engineering, design, and functions like sales, operations, marketing, and recruiting.
• Evaluate and integrate modern AI tools, then turn those learnings into secure, repeatable workflows the broader team can build on.

• 1+ years of experience in front-end engineering, design engineering, or product design with code.
• Strong foundation in React, TypeScript, HTML, and CSS.
• Sharp eye for visual quality, interaction detail, and product craft.
• Experience building with design systems, reusable UI, and modern prototyping workflows.
• Interest in AI-native product experiences and how AI tools are changing the way products are built.
• Strong collaboration skills across design and engineering.
• Builder mindset: proactive, thoughtful, and excited to learn by making.
• A portfolio that demonstrates strong UI craft, prototyping ability, and thoughtful implementation in code.

• Salary Range : $100,000 - $120,000 per year, commensurate with experience
