Fliff is seeking a Staff Platform Engineer to own and evolve the company's CI/CD and infrastructure platform. This is a high-impact individual contributor role focused on building secure, scalable, and maintainable systems that enable the entire engineering organization. Key Responsibilities: - Own and evolve the CI/CD platform, including GitHub Actions with self-hosted runners (RunsOn) and an in-progress migration/refactor of Jenkins setup ("Jenkins Next"). - Build and maintain Infrastructure as Code across AWS using Terraform, Terragrunt, and Terramate, following reusable component patterns (CloudPosse-style). - Design secure-by-default delivery pipelines with branch protection, PR approval rulesets, secrets management (SOPS), and production-approval flows for critical paths. - Drive migration from IAM users and long-lived access keys toward IAM roles, and help close foundational security gaps including open ports, unmanaged credentials, and missing guardrails. - Work with Kubernetes (EKS), Helm, and ArgoCD to support the observability stack (Grafana, Prometheus) and developer platform (Backstage). - Review and improve existing components—Terraform, pipelines, AWS infrastructure—not only build new ones, and raise the bar on how the team delivers. - Share the support/triage load and help reduce it through better automation and tooling. This role is ideal for a senior engineer who thrives on platform work, security-first thinking, and mentoring through example. You'll have significant autonomy to shape infrastructure strategy and drive technical excellence across the organization. Requirements: - Strong AWS experience and deep hands-on CI/CD expertise (GitHub Actions and/or Jenkins). - Solid Infrastructure as Code background with Terraform; Terragrunt/Terramate experience is a plus. - Real Kubernetes/EKS experience, including Helm and GitOps (ArgoCD). - Security-conscious mindset; comfortable reasoning about IAM, secrets, network exposure, and least-privilege access. DevSecOps experience is a strong plus. - Ability to design solutions and adapt gracefully when constraints change (scaling globally, cost optimization, etc.), with strong problem-solving and context-gathering skills. - Sound judgment on edge cases and incidents: ability to approach major incidents (10x traffic spikes, regional outages) methodically and handle outages effectively. - Effective and deliberate use of AI tooling, with genuine understanding of what it produces and the ability to explain trade-offs.
