Software Engineer Intern, Summer 2020

Engineering | San Francisco, CA

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 intern on our software engineering team, you’ll have a rare chance to create a direct impact on our products, while working on a modern infrastructure and receiving extensive training. You will be mentored and trained by senior engineers and Lob's founders to foster personal growth and a challenging but rewarding work environment.

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.

As an intern at Lob, you will:

  • Build new API product offerings from the ground up.
  • Improve upon existing API offerings to offer the best possible services and experience to users.
  • Develop systems that are scalable, maintainable, and secure.
  • Take on challenging problems in distributed systems, cloud computing, API design, and more.

For this role we’re looking for:

  • Experience working on the front or back end of web applications or APIs.
  • Experience working with web technologies, for example:
    • Relational databases
    • Modern languages like: JavaScript, Python, Ruby
    • Front end frameworks like React or Redux
  • Completion of your junior year of BS/BA (or first year of MS) in Computer Science or a related field by the start of Summer 2020 OR the completion of a coding bootcamp.
  • Hands on. Passionate. Persistent. Creative.
  • Strong communication, problem solving, and analytical skills.
  • Someone able to work full-time for the duration of the 12 week internship.
