Design Engineer (NYC)

About Us

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.

What’s Design Engineering?

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.

What You'll Be Doing

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.

Qualification

  • 1+ years of experience in front-end engineering, design engineering, product design with code, or similar work.
  • 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 curiosity about 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.

Benefits

  • Generous PTO plus paid company holidays
  • Comprehensive medical, dental, and vision plans
  • Access to healthcare and wellness programs
  • 401(k), commuter benefits, and HSA/FSA plans
  • NYC office located in the heart of SoHo, Manhattan
