We own Sidekiq at Braze—processing more than a trillion jobs daily across Kubernetes clusters worldwide. Our work spans autoscaling systems, metrics pipelines, reliable job execution, and internal frameworks that make distributed processing safe for application teams.</p> <p>Braze operates at a massive scale: 3.3 billion monthly active users, hundreds of billions of data points collected each month, and billions of messages sent daily. Our tech stack is rooted in Ruby on Rails, Go, MongoDB, Redis, and Kafka. As a PSWE, you'll collaborate with application teams to evolve the Sidekiq platform they depend on and improve the reliability, performance, and developer experience.</p> <p>Main responsibilities:</p> <ul> <li>Develop Braze’s embedded frameworks that enable large-scale distributed processing</li> <ul> <li>Design, build, and operate internal software frameworks that power Braze’s asynchronous and background processing systems at massive scale</li> <li>Evolve and extend frameworks built on technologies such as Sidekiq to reliably execute over a trillion jobs per day across a globally distributed platform</li> <li>Own scaling behavior, reliability guarantees, failure modes, and operational safety of these systems</li> <li>Provide opinionated abstractions, tooling, and guardrails that allow application teams to use distributed processing safely without needing to manage underlying complexity</li> <li>Improve observability, debuggability, and operational ergonomics for large-scale job-processing systems</li> </ul> <li>Manage incidents:</li> <ul> <li>Be on a PagerDuty rotation to respond to availability incidents and provide support for other engineers</li> <li>Use your on-call shift to prevent incidents from ever happening</li> <li>Retrospect everything that happens to turn lessons into system improvements/changes, automation, etc.</li> </ul> </ul> <h4><strong>WHO YOU ARE</strong></h4> <ul> <li>5+ years of distributed systems development or platform/infrastructure experience</li> <li>You think about systems - interfaces, boundaries, edge cases, failure modes, behaviors, and specific implementations</li> <li>Have an urge to collaborate, document, and deliver quickly <ul> <li>Collaborating across the global remote teams, often working asynchronously</li> <li>Document everything so you don't need to learn the same thing (or plan the same work) twice</li> <li>Delivering fast to delight our customers–<em>even internal ones</em></li> </ul> </li> <li>Have an enthusiastic, go-for-it attitude. When you see something broken, you can't help but fix it</li> <li>Have a desire to solve everyday challenges facing software engineers and automate their toil ...
