OfferUp is looking for a Tools developer to join our Operations Team.  We provide tools and services to all teams in OfferUp for managing an increasingly complex production infrastructure in AWS.  Our success is measured by our ability to allow everyone to build, test and deploy services and mobile applications quickly and safely. In this role you will work with the Engineering organization to improve developer productivity while reducing risk and removing friction.


  • Create and improve tools for continuous build and automated testing for backend services and mobile applications
  • Manage our source code repository and external software dependencies

  • Experience selecting, configuring and extending build tools (Pants), continuous integration tools (Jenkins) and test environments
  • Strong familiarity with Linux and internet technologies
  • Proficiency in one or more scripting languages more advanced than Bash
  • Configuration management tools like Ansible or Puppet

  • Experience working with cloud platforms, especially AWS
  • Knowledge of mobile application build and testing technologies, both iOS and Android
  • Experience deploying and operating production services
  • Experience with container technology, specifically Docker and Kubernetes
  • Slight obsession with metrics

Our team:

  • Acts like a team
  • Avoids doing things twice

  • Investigates, considers and adopts new technology where it makes sense
  • Takes risks and makes mistakes
  • Doesn’t tolerate brilliant jerks
