THE ROLE

As a Platform Engineer you will work in Certinia's Platform Engineering team, building and operating the platform on which Certinia's AI agents and services run. The platform is Kubernetes on AWS with a service mesh for zero-trust networking, and provides the runtime, identity, AI-gateway, cost-governance and audit layers that let AI workloads operate safely against customer Salesforce data.

You will work across the stack, from the Helm charts and Terraform that provision infrastructure, to the services that make up the platform's authentication and gateway layers, to the CI/CD pipelines and tooling that application teams rely on. Application teams are your primary users; you will help them ship features safely and efficiently.

You will deliver small to medium platform changes with general direction from more senior colleagues. You will work alongside peers of different competencies, contribute to reviews and retros, and share on-call responsibility for the platform.

WHAT YOU WILL DO IN THIS ROLE

• Contribute to the complete development cycle of platform changes: Helm charts, infrastructure-as-code, services, CI/CD jobs and supporting tooling.
• Add functionality to the platform through new code, configuration and infrastructure, or by changing what already exists.
• Write and maintain automated tests. Perform manual verification of changes in lower environments.
• Identify bugs and fix them. Address feedback from code reviews.
• Monitor platform components and participate in incident response and disaster-recovery exercises with support from senior colleagues.
• Demonstrate completed work to the team and the wider product group.
• Keep up with changes to the team's tech stack and to tools and techniques used by the team.

WHAT YOU NEED TO BE SUCCESSFUL IN THIS ROLE

• A development background in a meaningful programming language, we write Go, but are happy with experience in Java, Scala, Rust, Kotlin, C# or another systems-or-services language.
• Working knowledge of Kubernetes, deploying and debugging workloads, reading manifests, understanding services, ingress and basic RBAC.
• Working knowledge of a major public cloud, AWS preferred, but solid experience in GCP or Azure is fine.
• Experience with infrastructure-as-code, Terraform preferred, but any mainstream IaC tool is acceptable.
• Comfort on the command line and a solid grasp of Linux fundamentals.
• Networking fundamentals: TCP/HTTP, DNS, TLS.
• Git proficiency and experience with code review.
• Familiarity with CI/CD pipelines, Jenkins, GitHub Actions, GitLab CI or similar.
• A clear bias for automation and for fixing the cause rather than the symptom.

WHAT ELSE WOULD BE GREAT

• Hands-on experience with EKS or another managed Kubernetes service.
• Exposure to a service mesh (Istio, Linkerd).
• Experience with Helm.
• Familiarity with the Atlassian suite (Bitbucket, Jira, Confluence).
• Foundational cloud or Kubernetes certification (AWS Cloud Practitioner, KCNA, CKAD), passed or in progress.
• Any prior experience working in a team that owned a developer platform, shared infrastructure or developer tooling.
