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 feel 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.

What You’ll Do

Our core infrastructure receives hundreds of millions of tweets per day and serves tens of billions of API requests. We also serve over 2+ billion search queries per day, render hundreds of millions of ad impressions, and process hundreds of terabytes of log and interaction data daily.

As a member of the organization you will be dedicated to improving the reliability of our end-to-end platform.  Your work will integrate directly with Twitter's products. You will dive deep into gnarly operational issues; from the software, systems, automation, and process perspectives. You will understand the challenges around integrating disparate infrastructures into a new facility, processes and procedures. You will work with open-source technologies and the wider SRE community, and actively participate in the vision to move away from high operational cost tasks such as break/fix, cluster migrations, new service buildouts, abuse, etc.  You will contribute to services that can shrink and expand based on demand, self heal, automatically rollout, etc.

Your responsibilities include but are not limited to:

• You will perform deep dives into both systemic and latent reliability issues; partner with software and systems engineers across the organization to produce and roll out fixes.
• You will troubleshoot issues across the entire stack: hardware, software, application and network,
• You will drive standardization efforts across multiple disciplines and services in conjunction with embedded SREs throughout the organization.
• You will mentor SREs on standard methodology for everything from monitoring to troubleshooting complex code issues.
• You will identify and drive opportunities to improve automation for the company; scope and create automation for deployment, management and visibility of our services.
• You will participate in code reviews for projects primarily written in Java and Scala, built on open source libraries such as Finagle, and running on both physical and virtualized platforms.
• You will represent the SRE organization in design reviews and operational readiness exercises for new and existing services.

• Ability to prioritize tasks and work independently.
• Be adaptable and able to focus on the simplest, most efficient & reliable solutions.
• Track record of successful practical problem solving, excellent written and social communication, and documentation skills.
• B.S. in computer science or similar field or equivalent experience.

Desired Skills

• Ability to mentor on technical teams through design and implementation across an organization.
• Experience with existing open source projects such as Scribe, ZooKeeper and Apache Mesos.

One of the biggest challenges in open source is long-term sustainability. As a result, we are not just looking for quick fixes to the challenges that face Twitter; we're in it for the long haul. So that means building a diverse team that will bring different perspectives and ideas. It means having a healthy team that works hard, but that can also take time to recharge and enjoy life away from work. It means a team that is respectful of each other, of the work we are doing, and of the importance of enabling the public conversation. That's the team we're trying to build. Let us know if you want to join us.
