About the Team

Delivery Engine (The Print & Mail Team) is one of the core engineering teams at Lob. This team owns and maintains the Print & Mail pipeline which is the core of our business. We are responsible for fulfillment of millions of mail orders created by our customers every month. In 2017, we fulfilled 25M mail pieces and nearly tripled it by fulfilling about 70M in 2018. In 2019, we fulfilled over 75M mail pieces. We scaled our end-to-end mail processing pipeline by over 10x over the past year in order to meet our ever-growing business. We helped unlock a new revenue stream by building an international print and mail delivery network capable of supporting both US and international originating mail. We partner with our Operations team to build our global print and mail delivery network, the backbone of our business. While we scaled our end-to-end mail processing pipeline over 10x in the past year, some of the challenges we're currently working on revolve around reliability, automations and optimizations to help us operate at scale and scale further seamlessly to support an ever-growing business.

As a Software Engineer at Lob, you’ll...

  • Research, design, and build solutions to original problems pertaining to existing and new APIs. Everyone on our team gets to take ownership of problems—not just the most senior or tenured engineers.
  • Contribute to codebases in Node and Go in a hybrid microservices and serverless ecosystem.
  • Collaborate with Lob’s Operations team and external print partners to grow our global Print & mail Delivery Network.
  • Ingest and process reporting for millions of mail orders every day to give a mail piece by mail piece status to our customers.
  • Build tooling for Lob’s Operations team to help them manage our entire Print & Mail delivery network.
  • Work on exciting problems that revolve around safe & secure rendering of mail pieces, intelligent routing mechanisms, to name a few. 
  • Collaborate with stakeholders throughout Lob to troubleshoot business challenges, remove bottlenecks, and identify new opportunities for growth.
  • Measure the effectiveness of our engineering work, and use data to drive decisions to help our customers.
  • Coach and mentor other engineers.

For this role, we're looking for...

  • 6+ years of full-stack (backend, frontend, and database) experience in a modern web framework. Show us how you’ve used technology to solve problems.
  • Exceptional collaborators and communicators. At Lob, you win by helping others succeed. You have concrete examples of ways you’ve gone above and beyond to help the people around you meet their goals.
  • Experience building or working with APIs. It turns out that they’re are a lot harder to design and change than they are to consume. You have Strong Opinions about what good API design looks like, informed by real-world experience.
