Software Engineer (Systems) - Health Core Infrastructure

San Francisco, CA

Health is Twitter’s top priority and we need your help.


We build and maintain the large-scale, low latency distributed systems that power Twitter’s real-time feature computation, rule engine, and data exploration tools that keep spam, abuse, and adversarial accounts off of Twitter.


If you want to work on a team that does some of the most interesting technical work at Twitter, protects people from real harm, and has executive-level visibility, then this is the team for you.

Who We Are

We’re a team of systems engineers that builds and maintains the core infrastructure helping to protect the health of the public conversation. We’re motivated by interesting technical challenges -- our real-time feature computation and rules engine runs thousands of rules on half a million events per second -- as well as internal and external customer impact. We work closely with our customers in Trust and Safety, User Services and Data Science to provide a platform for technical and nontechnical customers to deploy new features and rules at scale in seconds.


Our work sits at the intersection of a number of interesting disciplines. We do large-scale real-time event processing that needs to catch some of the smartest adversaries. Our flexible platform serves numerous important internal customers. And we build and maintain a grammar, compiler, and tooling for a Turing-complete rules and feature computation language.


We deploy continuously, write unit tests, and do code review.

What You’ll Do

Here are some of the daily duties of the role:

  • Extend the functionality of the platform, including new language features and new integrations with other systems, to serve our customers’ needs.
  • Profile and stress test to surface inefficiencies in our system.
  • Tune cache and storage to optimize our runtime performance.
  • Diagnose issues and debug across the entire stack.
  • Work with platform services we depend on, including storage, messaging and data platform teams.
  • Give conference talks, write blog posts, and otherwise evangelize Twitter health engineering internally and externally.
  • Lead small, hungry project teams to impactful infrastructure wins.
  • Communicate with stakeholders and build consensus around the technical roadmap.

Who You Are

  • You’ve built and maintained a large-scale distributed system before and have the scars to prove it.
  • You value deleted code -- and code never written -- just as much as the code that you do write.
  • You’re willing to be coached and to coach others.
  • You know when it’s okay to take on technical debt and you eventually pay it down.
  • You can balance quality work vs customer requests vs new features.
  • You can make the right product and technical decisions independently.
