Your Task

This infrastructure and operations role focuses on establishing and operating the build, release, and observability backbone required for Meridian technical due diligence, code quarantine, reproducible software validation, controlled deployment preparation, and reliable engineering handover across cloud platform components. The role emphasizes CI/CD pipelines, artefact flows, release evidence, build reproducibility, observability, and operational controls. The candidate should make complex engineering environments measurable, supportable, and auditable while enabling AI-assisted code validation and documentation workflows.

Responsibilities

• Design and operate CI/CD pipelines for repository intake, build execution, image creation, artefact promotion, environment deployment, and evidence generation
• Implement release controls for private registries, package sources, signing, SBOM generation, vulnerability scanning, dependency provenance, and approval workflows
• Create observability across build systems, workflow services, repositories, test environments, model endpoints, and platform components using logs, metrics, traces, and dashboards
• Support troubleshooting of build failures, flaky pipelines, missing dependencies, environment drift, performance bottlenecks, and handover-readiness gaps
• Partner with software, SRE, testing, and security teams to define runbooks, operational KPIs, risk indicators, and audit-ready evidence packs for release decisions
• Work with CI/CD and release tools such as GitLab CI, Jenkins, ArgoCD, Tekton, GitHub Enterprise, Helm, Docker, Kubernetes, Kaniko, BuildKit, Nexus, Harbor, or Artifactory
• Utilize security and supply-chain tooling such as Trivy, Grype, Syft, Cosign, SLSA-oriented controls, SBOM workflows, dependency scanning, secrets detection, and policy gates
• Implement observability stacks such as Prometheus, Grafana, Loki, OpenTelemetry, ELK/OpenSearch, Alertmanager, log aggregation, dashboarding, and automated health checks
• Integrate AI engineering workflows such as code-scanning workflows, model-backed log analysis helpers, documentation generators, internal model gateways, and workflow execution services
• Manage infrastructure automation using Terraform, Ansible, Helm, Python, Bash, GitOps patterns, private networks, controlled proxies, package mirrors, and secure secrets management
