Discover Platform Engineer III jobs and advance your career at the intersection of infrastructure, automation, and developer enablement. A Platform Engineer III is a senior-level professional responsible for designing, building, and maintaining the foundational internal platforms that power an organization's software development and delivery lifecycle. This critical role focuses on creating scalable, reliable, and efficient systems that allow product development teams to deploy applications faster and with greater confidence, abstracting away infrastructure complexity. Professionals in these jobs typically own the end-to-end health of the platform. Common responsibilities include architectural design and implementation of core platform services, such as CI/CD pipelines, container orchestration (e.g., Kubernetes), infrastructure as code (IaC) frameworks, monitoring and observability stacks, and cloud resource management. They ensure the platform's compliance with security policies and governance standards through rigorous auditing, policy enforcement, and the implementation of robust security controls. A key duty is managing the platform's lifecycle, including planning and executing software upgrades, security patching, and capacity scaling to meet evolving demands.

To excel in Platform Engineer III jobs, a specific blend of advanced technical and collaborative skills is required. Typically, employers seek candidates with a bachelor's degree in computer science or a related field, coupled with several years of hands-on experience in DevOps, site reliability engineering (SRE), or cloud infrastructure. Advanced proficiency in modern programming and scripting languages (like Python, Go, or Java), along with deep expertise in cloud providers (AWS, Azure, GCP) and IaC tools (Terraform, CloudFormation), is fundamental. A strong understanding of containerization, orchestration, networking, and security principles is essential. Beyond technical acumen, successful Platform Engineers III possess excellent problem-solving abilities to troubleshoot complex system-wide issues. They demonstrate leadership by mentoring junior engineers, leading medium-scale projects, and collaborating effectively with cross-functional teams. Experience with Agile and DevOps methodologies, along with strong technical writing skills for documentation, rounds out the profile for these high-impact jobs. If you are passionate about building the robust foundations that enable engineering innovation, exploring Platform Engineer III jobs is your next strategic career move.
