About the role:

OfferUp is looking for an experienced developer to lead efforts for the Identity team. The team is responsible for building services that manage authentication, authorization, profile, ratings, and reputation of all customers in our marketplace. These services are critical for securing requests on our platform, handling user logins, customer sign-ups & registrations, and serving profile information for millions of buyers and sellers. They are also important for supporting our user growth across markets and delivering a trustworthy experience for OfferUp’s users. In many organizations, your role begins and ends with the code. On our team, we’re different. You own a feature from concept to fruition. Your responsibilities will include everything from writing well-architected and thoroughly tested code to rolling out the feature by analyzing metrics. You also get to take ownership beyond your technical area by working with cross-functional team members. 

Here’s more of what you will get to do:

  • Work collaboratively with cross-functional teams (Catalog, Billing, Integrity, Data Science) to design and implement new features
  • Drive engineering and operational excellence across OfferUp-wide Backend teams
  • Collaborate with OfferUp-wide engineering teams to improve processes, surface common pain points, develop solutions and evangelize best practices
  • Identify when to replace and when to rebuild legacy systems
  • Support, mentor, and help other engineers in the team
  • Participate in a reasonable on-call rotation with the rest of the team

You’ll thrive in this role if you have:

  • 8+ years of professional software engineering experience
  • 3+ years of experience developing web services
  • Experience performing data analysis and translating the results into business recommendations
  • Experience in working with data-driven applications at scale
  • Strong coding skills in Java, Python, Scala, Golang, or any other modern programming language coupled with strong knowledge in object-oriented design and microservices architecture
  • BS or MS in Computer Science, Computer/Software Engineering, Information Systems/Technology, Information Science, or a related discipline
  • Must be eligible to work in the United States
  • All OfferUp employees are required to receive Covid-19 vaccinations unless an employee requires an exemption from this policy due to a medical reason or a sincerely held religious belief.

Helpful, but not required:

  • Experience designing and delivering highly available, large scale distributed systems
  • Experience with security methods and communication transports (OAuth/OIDC, SSL/TLS, etc)
  • Experience building online user profiles, reviews, and rating services or algorithms
  • Experience writing code in Java or Python
