Job description: Senior Platform/DevOps Architect

Role
summary: 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 standardisation 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: org/repo@version) — 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 PRs for architectural
soundness.

- Partner with client platform/security teams; prepare the platform handover to client BAU.

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, setting 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.

Desirable: GEI migration
experience; Kubernetes; APRA-regulated environment exposure; contribution to
internal developer platforms / golden-path programmes.
