Job Description

Love cutting-edge tech? We do too.

Our mission is to personalize every digital display and video ad, on both mobile and desktop, by informing it with anonymous user data. Keyword: anonymous. Ad tech has a privacy problem and at Epsilon, we’re here to fix it.

We’re looking for a dedicated and passionate Software Engineer to help us transform the way marketers connect and interact with their consumers. When you join us, you’ll develop powerful systems and write effective tests across every layer of our primary ad tech CORE platform. From processing petabytes of data to making bid decisions in under 10 ms over 5 million times per second, you’ll help us do some truly astounding things.

Better yet, we’re growing fast, which means you can too. From learning new technologies to collaborating with some of the brightest—and kindest—people in the world, there’s a lot to love about a career with us. Join a team where you’re empowered to do epic things and unleash your full potential.

What you’ll do:

  • Build high-performance, low-latency software at scale that supports our ad delivery platform.
  • Write performant, efficient and maintainable code based on requirements.
  • Locate performance bottlenecks and troubleshoot critical production issues.
  • Recommend new technologies to enhance the existing platform.
  • Learn from some the best and brightest in the industry while using modern technology and techniques.

About you:

  • You thrive on new and interesting challenges
  • You focus on the customer, not just the code
  • You like to brainstorm multiple solution but quickly land on the best solution
  • You want to grow your career with a great organization

What you’ll bring:

  • B.S. in Computer Science, Computer Engineering, or related field.
  • Strong development practices with experience writing and testing code.
  • 2+ years of experience.
  • Applied experience programming using modern object-oriented and functional languages such as Java, JavaScript, Scala, Python, C/C++, or similar.
  • Proficient in at least one modern programming language, preferably Java or client-side JavaScript.
