Senior API Engineer, Campaign Management Services

Quantcast is programmatic advertising that works, because it's powered by our massive data set and strong predictive models. You're a driven, pragmatic, goal-oriented innovator, who is going to push the boundaries of advertising technology.

You are an authority on API development who is excited to open our real-time advertising infrastructure to our customers. These systems drive our entire advertising business and you'd love to make a significant impact on our bottom line.

You’ll develop these projects on an eclectic mix of Python, Go, Java, Scala, and JavaScript, all on top of Amazon Web Services. But you might suggest some new ideas?

You will:

  • Design and implement APIs that expose our technology to internal and external customers.
  • Split our monolithic systems into sensible, modular services.
  • Build internal tools to monitor and repair our API infrastructure.

You have:

  • Bachelor’s degree in Computer Science, Electrical or Computer or Software Engineering, Pure or Applied Mathematics, or equivalent degree. Master’s or Ph.D preferred.
  • 5+ years of professional software engineering experience.
  • 2+ years designing or developing real-world Application Programming Interfaces (APIs).
  • Proficient in: Java, C++, Python, Ruby, or another object-oriented programming language
  • Experience with Linux or UNIX production environments, with AWS experience preferred.

Bonus traits:

  • Mentored junior developers to grow their careers and deliver outstanding results.
  • Strong experience (and strong opinions about) crafting production services.
  • Polite but assertive personality, thanks. You criticize work, but never people. :)
  • Open-source contributions and/or projects. GitHub, please?
  • Experience deprecating and replacing legacy systems, without breaking everything.

Campaign Management Services is:

  • Developer driven: your pick your own technology stack, but you share our infrastructure.
  • Friendly and professional: you're positive, a great teammate, and respect diverse voices.
  • Nerdy at heart: both our founders were engineers and you love Hackathons.
  • Employee supported: you’ll enjoy full medical, dental, vision benefits; 401(k) plans; free meals; commuter benefits; and more.
