- 8 to 14+ years of overall experience in Infrastructure and Cloud services
- 8+ years of DevOps and CI/CD experience
- 1+ years of Harness tool experience
Harness CI/CD DevOps Engineer (Migration Factory) executes wave-based, repeatable Jenkins → Harness migrations using a factory operating model: Intake → Convert → Remediate → Validate → Cutover → Stabilize, while driving standardization through golden templates, enterprise integrations (SCM/artifacts/secrets), and controlled legacy CI/CD decommissioning.
Core Mission
• Industrialize CI/CD migration using waves, playbooks, reusable templates, and validation gates to reduce delivery risk and improve consistency.
• Leverage Harness Jenkins Migrator to scan/analyze pipelines, convert Jenkins pipelines to Harness format, and consolidate into reusable templates (where applicable), reducing manual effort and operational risk.
• Deliver controlled cutovers and stabilization while enabling governance elements (approvals, evidence capture) and controlled Jenkins decommission actions.
Key Responsibilities (Migration Factory Scope)
1) Migration Intake, Inventory & Segmentation
• Perform Jenkins estate discovery: inventory pipelines/jobs, Jenkins files, shared libraries, credentials usage, build agents, plugins; map dependencies and owners.
• Classify pipelines into complexity buckets (e.g., Quick Win/Simple, Standard/Medium, Complex) and build wave backlogs for migration execution.
• Run migrator assessment to produce a conversion readiness report and list of unsupported patterns (to drive remediation plan).
2) Platform Foundation for Migration
• Implement hands-on readiness required for factory execution: validate network allowlists/proxy/firewall, and ensure delegates/runners are deployed and healthy in target environments.
• Configure and validate connectors for SCM, artifact repositories/registries, cloud/K8s targets, and secret stores (Vault / secrets integration where applicable).
• Establish/maintain operational runbooks for delegate installation, access troubleshooting, and credential rotation.
3) Convert + Standardize via Golden Templates
• Use Harness Jenkins Migrator for bulk conversion and initial YAML generation where applicable.
• Refactor conversions to adopt golden templates (build/test/package/scan/deploy/notify patterns) and replace ad hoc logic with reusable templates/modules.
• Translate Jenkins constructs into Harness equivalents:
o shared libraries → templates/steps/stage templates
o Jenkins agents → delegates + build infrastructure model
o credentials → connectors + secrets manager
4) Remediate Gaps
• Replace unsupported Jenkins plugins / Groovy patterns with Harness-native steps or agreed scripts, and convert shared-library logic into reusable templates/modules.
• Integrate required enterprise toolchain hooks (e.g., artifact management, code quality gates, smoke tests), aligned to app team inputs.
5) Validate Shadow Mode & Parity Checks
• Execute parallel runs (Jenkins + Harness) for validation; compare outputs (artifacts, test reports, scan outputs) and complete acceptance testing checkpoints.
• Produce a validation evidence package (shadow run results + parity checks) to support cutover readiness and audit needs.
6) Cutover & Stabilize (Hypercare within the factory cycle)
• Execute cutover by switching triggers/webhooks/notifications to Harness and keeping Jenkins as rollback for a defined period when required by the plan.
• Stabilize builds by monitoring failures, tuning caching, adjusting runner sizing, and addressing recurring pipeline issues; capture improvements back into templates/playbooks.
• Run wave retrospectives to update templates, playbooks, and known-issues guidance for the next wave.
7) Controlled Jenkins Decommission (Factory Exit)
• Support controlled Jenkins reduction activities as defined by the migration plan:
o Freeze new pipeline creation in Jenkins (new work lands in Harness)
o Progressive shutdown (disable triggers → jobs → agents; keep read-only for audit retention)
o Plugin & credential cleanup (remove unused creds, rotate secrets, lock down access)
o Archive evidence (export build history/logs as required)
o Terminate Jenkins infrastructure and reclaim resources
Factory Delivery Model Alignment (Pods & Interfaces)
• Work within a pod-based migration factory model that includes:
o Platform Pod: templates, delegate strategy/connectors, enterprise integration, org/account governance, policy enforcement, service catalog enablement
o Migration Pod: Jenkins inventory & dependency analysis, wave planning, pipeline migration/validation, cutover support, runbooks/handover, hypercare, and decommission support
Required Skills
Harness CI/CD Execution
• Hands-on ability to build and migrate CI/CD pipelines and enforce reuse through templates and versioning.
• Experience deploying and operating delegates/runners, and troubleshooting connectivity/toolchain access.
Migration Engineering (Jenkins → Harness)
• Strong experience analyzing Jenkins pipelines (Jenkins-files, shared libraries, agents, plugins, credentials) and translating them to Harness equivalents.
• Familiarity with AI-assisted conversion using Harness Jenkins Migrator and handling unsupported patterns through remediation/refactoring.
Validation & Cutover Discipline
• Experience with parallel/shadow runs, artifact/output comparison, readiness checkpoints, and cutover + stabilization practices.
Enterprise Integrations & Secrets
