About the role:

OfferUp is looking for an experienced developer to lead efforts for the Communications team. The Communications team builds systems that enable a real-time conversation between Sellers & Buyers. These systems are one of the highest queries per second (QPS) service at OfferUp. The main challenges are: building a platform that can scale with our growing user engagements (millions per day) with optimal latency and creating an OMNI-channel messaging platform to enable OfferUp to communicate with our users.

At 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. 

As an experienced developer in our team, you will set the technical strategy for our team, build highly scalable real-time messaging systems and continuously improve our engineering/operational excellence.

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

  • Develop a technical strategy for our team
  • Develop highly scalable real-time messaging pipelines without compromising on reliability, latency, and monitoring
  • Build OMNI-channel messaging platform to enable OfferUp to communicate with its users (Email, Push notifications, Web-hooks)
  • Work collaboratively with cross-functional teams (Marketing, Commerce, Integrity) to design and implement new features
  • Drive engineering and operational excellence across Communications team and OfferUp-wide Backend team
  • Collaborate with OfferUp wide engineering teams to 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 rotations with the rest of the team

You’ll thrive in this role if you have:

  • 5+ years of professional software engineering experience, of which at least 3 were devoted to web services
  • 2+ years of experience in real-time messaging systems
  • 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

Helpful, but not required:

  • Experience with load balancing, and handling massive data traffic
  • Experience writing code in Python or Java
  • Experience in building microservices
  • Experience with cloud infrastructure AWS

An Insider's view of OfferUp

What's something quirky about your company?

This may seem silly, but we have a 90lb MMA dummy our CEO bought and named Pat. On a daily basis, someone will take Pat and figure out creative ways to scare some folks in the office. How do I know? I am Pat.

What does your typical day look like?

One of the great things about OfferUp is that no two days look the same. The only thing you will see me do every day at the same time is plank at 3 p.m. with my team. Otherwise, who knows?

Julien

Software Development Engineer

What makes someone successful on your team?

Like many engineers, one of my favorite parts of being in tech is using my creativity and logic to create something new, especially here at OfferUp where what we create has the ability to help the environment and enable people to support their own businesses.

What is your vision for the company?

OfferUp will continue to be the premier local mobile marketplace for buying and selling, but there will likely be more and better e-commerce opportunities with the onset of new delivery technologies. OfferUp has such unique purpose and is leading the transformation of how consumers buy and sell locally. I'm delighted to be a part of the team.

How would you describe the company’s work-life balance?

Work/life balance is fantastic at OfferUp, especially for a startup! Sure, there are some days you may need to stay late- but everyone is pitching in here and understands the importance of recharging and resetting.
