Library Software Engineer - APM Ruby Tracer

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 real 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.

At Datadog, we place value in our office culture - the relationships and collaboration it builds and the creativity it brings to the table. We operate as a hybrid workplace to ensure our Datadogs can create a work-life harmony that best fits them.

The Team:

The APM Team at Datadog provides mission 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 open source software!

What You’ll Do:

• You will build open-source code that instruments thousands of Ruby applications around the world.

• You’ll help drive our open 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 cutting-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 ActiveRecord.

• 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, high 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, low level OS details, and how to safely ship software that runs within customer processes at scale.

• Opportunities to contribute to open source software.

• You’ll have a lot of influence on product direction and impact on the business, especially since we continue to grow quickly.

• Competitive global benefits.

• Continuous professional development.

Benefits and Growth listed above may vary based on the country of your employment and the nature of your employment with Datadog.
