Twitter is one of the largest and most popular platforms in the world. Our code operates at massive scale and speed, serving billions of requests per day, connecting hundreds of millions of active Twitter users to real-time information about their lives and the world we live in.

Twitter is what's happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation

Our team is responsible for providing Twitter Engineering with a scalable, reliable and performant compute platform. Our infrastructure powers most of the services behind Twitter.com, Twitter’s revenue-generating businesses, and a variety of internal infrastructure. Twitter’s 1,000+ engineers use our compute platform to launch and operate their services on a fleet of over 100,000 physical and virtual machines.

Our primary focus is scaling and operating the company's largest compute clusters, which are managed using Apache Aurora and Apache Mesos. This includes providing lower-level interoperation between Mesos and the datacenter stack together with the user-facing aspects of the Aurora/Mesos compute platform. Our systems drive availability and infrastructure efficiency for the Twitter platform. We need to expand Aurora and Mesos capabilities beyond the industry standards to meet the growing scale at Twitter.  

In this role, you’ll:

• Build the tooling and processes that Twitter engineers use to develop, deploy, and operate their services.

• Optimize Aurora/Mesos cluster scheduling in the thousands of nodes.

• Be an active participant in our systems design and review processes.

• Scope out, participate in, and lead cross-functional projects.

• Develop our team through mentorship and knowledge sharing.

• Influence the team’s roadmap based on feedback from our internal customers.

Who you are:

• You draw motivation from building systems that help others be more productive.

• You are curious and driven to understand the needs of your customers.

• You are an engaged and thoughtful collaborator, ready to solve challenging problems with your peers and our customers.

• Simplicity and approachability are top of mind concerns when designing systems and tooling.

• Quality and reliability are key pillars in your software engineering philosophy. 

• You see mentorship and knowledge transfer as essential prerequisites for a healthy team.

• BA/BSc degree in Computer Science or equivalent practical experience.

• Strong development skills in at least one programming language.

• Hands-on experience designing, developing, operating, and debugging distributed systems.

• 5+ years of experience in Infrastructure or Backend development.

While not required, experience with any of the following is a plus!

• Production experience with Python, Java, or C++.

• Experience developing, operating, and debugging high traffic production systems.

• Experience building scalable distributed systems.

• Familiarity with Apache Mesos and Aurora internals (architecture and/or codebase).

• Experience with container-centric orchestration systems (Mesos, Nomad, etc).

• Experience working with physical infrastructure (bare metal in data centers).

• Familiarity with Linux or similar operating systems.
