Iru•Miami, FL

About The Position

Iru is the AI-powered security & IT platform used by the world’s fastest-growing companies to secure their users, apps, and devices. Built for the AI era, Iru unifies identity & access, endpoint security & management, and compliance automation—collapsing the stack and giving IT & security time and control back. Iru is backed by some of the smartest investors in tech—General Catalyst, Tiger Global, Felicis, Greycroft, and First Round Capital. In July 2024, Iru raised $100 million from General Catalyst, valuing the company at $850 million. Customers include Cursor, Vercel, Lovable, Replit, and Mercor, and Iru partners with industry leaders such as ServiceNow and AWS. Iru was named to Forbes’ America’s Best Startup Employers 2025 list for employee engagement and satisfaction. The Opportunity: We’re looking for a craftsperson, a maker. You will own the visual and experiential quality of our most important surfaces, translating genuinely complex security and compliance concepts into interfaces that feel clear, confident, and effortless. We’re looking for someone obsessed with the craft. Optical alignment, type and color rhythm, motion easing, the weight of a border, the exact gray of a disabled state; these are not afterthoughts here, they're the job. You’re the kind of designer who sweats ascenders, descenders and x-height of any typeface we’d use for UI.

Requirements

8 to 12+ years designing and shipping high-quality product UI with a portfolio that clearly demonstrates exceptional craft.
Strong visual design fundamentals, including typography, color theory, hierarchy, composition , and attention to detail.
Strong interaction design instincts, including comfort with motion and micro-interactions (not necessarily motion graphics).
Expertise in Figma.
Proven ability to partner closely with engineers and maintain quality through implementation.
Clear, direct communicator with strong taste and the ability to explain decisions and tradeoffs.

Nice To Haves

Background in craft-heavy environments, including teams or companies known for world class design quality (consumer or B2B).
Experience that bridges product design with graphic design, art direction, or agency work.
Design system experience is a plus, but not required if your craft level is exceptional.
Familiarity working with component libraries and design systems implementations (for example Storybook) is helpful.
Comfort using AI tools to iterate is a plus, but this role is not centered on being “AI-first.”

Responsibilities

Lead the visual redesign of our entire product: Define a new visual language, then drive it across core surfaces.
Set and raise the craft bar across UI quality, typography, color, layout, visual hierarchy, spacing, and polish.
Push interaction patterns and motion: you do not need to be a motion specialist, but you should have strong instincts for animation and micro-interactions.
Make opinionated, high quality UI decisions: elevation, shadow, materials, and what trends to adopt lightly versus avoid.
Use UI kits as a baseline, not the finish line: extend and refine patterns rather than defaulting to generic components.
Partner tightly with Engineering and the Design Systems team to ensure what we design is buildable, consistent, and shipped with quality.
Collaborate with the UX team to translate product needs into a “kick ass” experience.
Contribute to system evolution: help establish principles and direction that the design systems team turns into scalable components and patterns.
Be hands-on: this role is about doing the work at a very high level of craft, not only reviewing or directing.
