Senior Platform/DevOps Architect - Sydney

AYAN InfoTech is looking for Senior Platform/DevOps Architect to join an exciting project based in Sydney. The role offers you the opportunity to contribute towards an extremely well structured and mature environment, working on sophisticated enhancement projects.

Role: Senior Platform/DevOps Architect

Location: Sydney

Contract Duration: 6 Months with high possible extensions

Experience: 7+ Years

Role Overview: Technical owner of the target platform. Designs and builds the GitHub Enterprise Cloud landing zone and the golden-path reusable workflow library that every migrated repository consumes - the standardization layer the whole migration lands on.

Key responsibilities:

• Design the GHEC foundation: org/repo topology, SSO/SCIM identity integration, Rulesets, branch protection, CODEOWNERS strategy, and marketplace/actions allowlist governance.
• Author and version the golden-path reusable GitHub Actions workflows per archetype (Java/Maven, Node/TS, Python, container, Terraform, etc.), consumed by reference (uses: - never copied - with drift detection.
• Design the self-hosted runner topology (residency-aware, Azure/AWS network routes) and integrate enterprise tooling: GHAS (secret/code scanning), Snyk/Sonar-class scanners, Vault/CyberArk, Artifactory.
• Define the Jenkins?Actions conversion standards the AI agents implement: secrets re-binding, shared-library equivalence, trigger mapping, artefact handling (including Git LFS / artefact-store strategy for large in-repo binaries).
• Act as design authority on the bespoke long-tail - the complex pipelines agents can't fully convert - and review agent-generated for architectural soundness.

Required skills & experience:

• 12+ years platform/DevOps engineering; 4+ years deep GitHub Actions (reusable workflows, composite actions, self-hosted runners at scale).
• Expert Jenkins internals: declarative and scripted pipelines, shared libraries, multibranch, trigger graphs - and Bitbucket Server administration.
• Enterprise CI/CD architecture: promotion models, environment strategy, secrets management, policy-as-code.
• GHAS or equivalent AppSec tooling integration; IaC (Terraform) for platform provisioning.
• Strong written design skills - ADRs, standards, runbooks that survive handover.
