Platform Engineer II

<p>Our mission at Duolingo is to develop the best education in the world and make it universally available. It’s a big mission, and that’s where you come in!</p> <p>At Duolingo, you’ll join a team that cares about finding <a href="https://blog.duolingo.com/tag/engineering/?utm_source=greenhouse.com&amp;utm_medium=referral&amp;utm_campaign=engblog_gh_091224">innovative solutions to complex technical problems</a>, running countless experiments (300+ at a time!) with our massive user base to make data-driven decisions, and educating our users and employees alike. You’ll have limitless learning opportunities, mentorship and collaboration with world-class minds, and a variety of projects with large scopes — while doing work that’s both fun and meaningful.&nbsp;</p> <p>Join our life-changing mission to develop education for our half a billion (and growing!) learners around the world.</p> <hr> <p style="text-align: left;"><strong>About the role...</strong></p> <p>As a Platform Engineer on the Compute team, you’ll improve how engineers build and run services, helping ensure our compute platform is reliable at scale for our learners and fellow Duo engineers.</p> <p>The Compute team builds and operates the core compute platform that powers our applications. We build paved roads (self-service platform primitives, templates, and tooling) and we operate them so product engineers can focus on shipping features with confidence.</p> <p><strong>🧠&nbsp; You will...</strong></p> <ul> <li>Build and operate core compute primitives that power production workloads based on Kubernetes, across different regions and cloud providers.&nbsp;</li> <li>Improve the delivery pipeline from commit to production by evolving our GitOps and deployment patterns, making rollouts safer and faster.</li> <li>Raise the operational bar: define SLOs, build dashboards/alerts, write runbooks, and participate in on-call/incident response to keep the platform dependable.</li> <li>Enable effective self-service by turning platform capabilities into reusable abstractions.</li> </ul> <p><strong>✅&nbsp; You have...</strong></p> <ul> <li>Strong problem-solving skills and experience delivering and shipping pragmatic solutions in production environments.</li> <li>Experience with distributed systems fundamentals (networking, service-to-service communication, failure modes, caching/storage concepts).</li> <li>Experience working on production systems (through industry roles, internships, or substantial open-source work).</li> <li>Experience with one or more CI/CD tools (Jenkins, Argo CD, GitHub Actions) and infrastructure management tools (Terraform, CloudFormation)</li> <li>Clear written and verb
