Justin Van Slembrouck

I’m a product designer and leader based in Brooklyn Ann Arbor, with deep experience building digital products. I’ve worked across tech companies, startups, and hardware projects, creating solutions for small businesses at Square and Meta, and media platforms for Adobe and The New York Times. As the founder of Modern Sounds, I also design synthesizers, combining my product expertise with a passion for creative tools.

Square for Retail

Square for Retail

At Square, I led the Retail design team through a full redesign of the point-of-sale (POS) app, building on the company’s original vision while meeting the evolving needs of established retailers. As Square and its customers matured beyond the initial card reader, we recognized the need for a solution tailored to complex retail operations, including inventory management and multi-channel sales. Our redesign achieved product-market fit, laying a solid foundation to address the increasingly sophisticated demands of Square's retail merchants.

“Stealth startup”

“Stealth startup”

At a large stealth startup, I led a global team of six designers in creating innovative tools for the restaurant industry, including a next-gen POS system, cross-platform kiosks, web ordering solutions, and marketing tools. I focused on cultivating team growth through mentorship, enhancing hiring and career development processes, and fostering a collaborative, high-impact design culture that elevated the product team as a whole. I can share more details about this role in person.

Meta

Meta

As a product designer on Facebook's Local team, I helped bridge local businesses and their customers, designing intuitive experiences that drove real-world engagement and meaningful value for both sides of the community. My work spanned local search, an integrated ordering platform, and the creation of a unified discovery experience for nearby events and places.

Modern Sounds

Modern Sounds

I started a hardware-focused company called Modern Sounds where I developed Pluto, a portable modular synthesizer now sold at retailers around the globe. I combined my product expertise with new skills in PCB design, electrical engineering, and C programming to bring it to market. It’s been a rewarding journey, and I have a few product concepts in development for future release.

Instapaper

Instapaper

As soon as I got word that Instapaper was acquired by betaworks, I insisted on leading the design. We took this already well-loved mobile app from a swiss-army-knife utility to a beautiful, cross-platform reading experience. I commissioned Klim Type to create a logotype, curated the type choices, and redesigned the app from top to bottom, all with the aim of creating a transparent and timeless design. After the redesign, I helped hire and mentor a team to continue the work.

Digg

Digg

When betaworks acquired Digg, I led the design transformation of the once-great community website into a curated media company (in just six weeks!) that delivered the best content from across the web. We built a team of editors and armed them with smart curation tools powered by data from across the web. We went on to expand from a lean, curated experience with millions of daily users to a media company that included a live AMA product, video curation, multiple emails, an RSS reader, and a native advertising platform. I wrote a post about our approach to curation, which I think is still relevant.

Type Sample

Type Sample

I created Type Sample as a tool for identifying and sampling webfonts. If you're a designer, think of it as a personalized type specimen book for all the fonts on the web. The project started as a simple tool I made for myself with the help of some friends to a resource that designers around the world use every day. Type Sample is now part of Typewolf, an independent typography resource.

The New York Times

The New York Times

At Adobe, I focused on working with publishers to explore new publishing platforms. Working with The New York Times R&D team, I led the product design for Times Reader. The Times was just starting to reinvent itself as the digital news standard bearers they are today. The app brought a number of important firsts (and some patents) for both The Times and Adobe, including, innovations like webfonts and responsive layouts.

Adobe Digital Publishing

Adobe Digital Publishing

At Adobe, I worked with top publication design teams at a moment when digital publishing was coming into its own. With the iPad launch approaching, I embedded with Scott Dadich and his team at Wired and Wyatt Mitchell at The New Yorker to envision how to bring the magazine experience to this new device.
