Senior Data Engineer

Engineering | San Francisco, CA

Lob is building a suite of APIs to simplify and automate enterprise workflows. Our most popular product is our print and mail API that enables companies to send physical mail as effortlessly as sending emails. Our first API helps you programmatically send physical mail at scale. Our second is address verification—officially CASS-certified by the USPS. But our long-term goal is to provide the building blocks for developers to automate the offline world through APIs. We’re looking for great problem-solvers to help us figure out how.

As an early member of our data team, you will help lay the foundation for a trusted and performant data platform that enables the entire company to make rapid data-driven decisions and ship scalable data-driven features. You will work with stakeholders across the company such as Sales, Finance, Marketing, Operations in addition to Data Science and Product/Engineering.

The role includes significant autonomy towards defining problem spaces and a mandate to build viable systems that are both internally- and externally-facing. This is a great opportunity for someone who wants to have a large sense of ownership, grow extraordinarily in their career, and develop cross-functional skills to maximize impact in a fast-moving hypergrowth startup.

Our engineering team values agility, collaboration, and autonomy. We’re building a team of not just strong problem-solvers, but great collaborators—engineers who are excited to teach and learn from each other, share decisions and information freely, and work together on new problems that no other companies have solved before. Come join the best people in the business.
