Sr Staff Backend Engineer - ShiftLeft (Cortex Cloud)

ShiftLeft is building the cloud security platform for developers (CAS). Our platform empowers teams to find, fix, and prevent security risks in application code and infrastructure as code through automation and security-as-code principles. We're looking for a skilled Senior Backend Engineer to join our team and contribute to our Cortex Cloud platform.
As a Senior Backend Engineer, you'll have a high-impact role in shaping the future of our code security products. Beyond building robust and scalable backend features, you'll help drive performance, reliability, and innovation across our systems. Our team leads the way in owning both the departments core infrastructure and Developer Experience (DevEx), empowering the entire engineering organization with powerful internal platforms and tooling. If you're excited by technical challenges, meaningful ownership, and making life easier for developers this is the place for you.
Your Impact
Feature Development: Design, build, and maintain robust backend services using TypeScript/Node.js. Take full ownership of complex, cross-system features from initial requirements through architecture, implementation, and deployment.
Build and Optimize Scalable Systems: Ensure performance, reliability, and cost-efficiency across distributed systems through thoughtful design, deep observability, and continuous optimization.
Platform Engineering & DevEx: Drive platform engineering initiatives by developing the department infrastructure and shared tooling that boost scalability, reliability, and the developer experience across the department.
Own Core Infrastructure: Design, operate, and evolve the departments infrastructure stack including BigQuery, MongoDB, Redis, and Argo Workflows using cloud-native technologies like Terraform, Kubernetes, and Helm.
