Software Engineering Intern – Summer

Responsibilities

• Ship real code:
  Design, build, and ship features that run in production and reach real users, not throwaway prototypes.
• Own a meaningful problem:
  Take a defined piece of work from design through delivery, with the support of your engineering manager and teammates.
• Build across the system:
  Develop and improve the services, APIs, and experiences that power Offer Up, and learn how the pieces fit together end to end.
• Move fast and do spike work:
  Investigate open-ended problems, prototype solutions, and turn technical spikes into clear recommendations the team can act on.
• Leverage AI tools:
  Use tools like Claude and Gemini to ramp up faster, navigate the codebase, accelerate spike work, and raise the quality of what you ship.
• Collaborate across the team:
  Work closely with engineers, product managers, and designers to turn ambiguous requirements into shipped, well-tested features.
• Care about quality:
  Write tests, participate in code reviews, and help keep our systems observable, reliable, and maintainable.
• Present your work:
  Share what you built and what you learned with the broader engineering and product teams at the end of your internship.

• Currently enrolled in an undergraduate or graduate (or equivalent) program, returning to school after the internship.
• Prior internship or project experience building software in a team setting.
• Familiarity with Java or a similar programming language.
• Exposure to cloud platforms, databases, APIs, or distributed systems.
• Experience with two-sided marketplaces, mobile apps, or large-scale consumer products.
• Comfort using AI coding assistants as part of your day-to-day workflow.
