The Warby Parker Data Book

At Warby Parker, our data dictionary is hugely valuable. Prior to its existence, we had no assurance that analysts on different teams were using the same definitions to define metrics and, even when metrics were defined, we had nowhere to document them. Now, everybody speaks the same language. Developing this source of truth was a … Read More >

Systems Development Gamified!

We had an issue: Our Engineering team expressed concerns about “Initiatives”, a process Warby Parker developed to request, prioritize, and assign development work—called into question were flexibility, empowerment, and effectiveness. As done with all processes, we looked to improve and iterate. This came in the form of selecting a cross-functional group of stakeholders to participate … Read More >

Serving a Single Master

As our organization evolves, the static nature of some of our tried and trusted processes can result in conflict between where we are as a company and how productive our processes enable us to be. One area that our Tech team recently decided to reexamine was our process for deploys. Our Systems Development team is … Read More >

We Can See Clearly Now

Once upon a time at Warby Parker, our process for requesting and verifying transfer orders was extremely manual. Our Supply Chain team would communicate with our warehouses and labs to verify everything was where it needed to be. While this process worked, it was incredibly time-consuming for our internal team—and we knew we could do … Read More >

Finding the Right Words

At Warby Parker, we get a lot of tweets. Our social media team does a great job of responding to each one and recording various metadata that the team uses for reporting purposes. One type of post that we often see from our Home Try-On customers is an informal poll to Warby Parker, friends, and … Read More >

A Better Build

Back when we designed our retail networks, we realized that we had to also create a scalable and robust WAN architecture for our retail expansion. With this, came the tough decision of which technologies to use: basic IPSEC tunnels, dynamic VPN protocols, or a managed MPLS network—to top it off, we had limited experience with all … Read More >

Emails: Communication Breakdown

We had a conversation problem. We at Warby Parker think of the Home Try-On email series as a conversation between our customers and us. Although, when we recently took a step back and examined how we were doing, we realized our conversation wasn’t going so well. We weren’t listening. By filling up a Home Try-On box, each customer … Read More >


  Like all good Tech Ops teams, we at Warby Parker are fanatical about monitoring. We utilize a number of tools to monitor the full stack; from Nagios for our server infrastructure to Keynote for real user perspective on our page load speeds (and lots more in between)—all integrated with PagerDuty and our on-call rotation. … Read More >

The First Annual Annual Report Report

The Annual Report is one of the most visible projects we produce at Warby Parker. There are months of work, dozens of people involved, and technical challenges from start to finish. The launch is also historically our highest-traffic day of the year and drives the desire to deliver something even better the following year. That’s … Read More >

One Store, Four Networks

Our move into brick-and-mortar stores brought many challenges, including creating a retail experience that is on brand and leveraging technology to create this experience. In pursuit of this goal, we had numerous, seemingly disparate network needs: those of employees, POS systems, vendor equipment, and public guest access. Each one of these also had separate requirements to … Read More >
