Job Reference: 470cc80e37c9

Job Description:

We're on a mission to build the best platform in the world for engineers to understand and scale their systems, applications, and teams. We build highly scalable systems that process trillions of data points every day to provide
- time alerts, visualizations, log aggregations, and application traces for tens of thousands of companies. Our engineering culture values pragmatism, honesty, and simplicity to solve hard problems the right way.

The Team:

The APM Team at Datadog provides
- critical application health and performance monitoring for customers of all sizes and industries. We’re taking a new approach to APM with distributed tracing, profiling, dynamic instrumentation, and seamless integration with Datadog’s Infrastructure and Logs products.

We are looking for an expert Ruby engineer experienced with Ruby language internals who can help push our tracing tools to the next level. Come and join us to build amazing
- source software!

What You’ll Do:

• You will build
  - source code that instruments thousands of Ruby applications around the world.
• You’ll help drive our
  - source Ruby projects and engage with the community to find and address the most important challenges.
• You’ll contribute to our distributed tracing libraries – adding
  - edge functionality and debugging tricky problems.
• You’ll be part of the Ruby guild at Datadog, interacting with engineers building profiling and security products.

Who You Are:

• You’re a master Ruby programmer. You think in blocks, faced the GIL limitations many times and you know there is more to Ruby than Rails. You have solid experience with widely used frameworks and libraries like Rails, Sinatra, Grape, Sidekiq, or Active
  Record.
• Hands-on experience in software design and leading refactoring initiatives to improve the architecture of complex software libraries.
• You want to work in a fast,
  - growth startup environment.
• You’re attentive to details and can build software with very low defect rates. You appreciate simplicity as a tool to accomplish this.
• You’re interested in an environment that values shipping early and iterating, and keeping processes to the minimum needed to ensure safety. You enjoy owning projects and can keep moving forward despite the occasional ambiguity or blocker.
• Bonus Points: You have experience with JRuby and how it works in the JVM or/and you’ve used/looked into eventmachine.

Datadog values people from all walks of life. We understand not everyone will meet all the above qualifications on day one. That's okay. If you’re passionate about technology and want to grow your skills, we encourage you to apply.

Benefits and Growth:

• Skilled, knowledgeable, and kind teammates to work with and learn from.
• Interesting challenges of all sorts. You’ll gain experience with runtime internals,
  - level OS details, and how to safely ship software that runs within customer processes at scale.
• Opportunities to contribute to
  - source software.
• You’ll have a lot of influence on product direction and impact on the business, especially since we continue to grow quickly.
