Role Summary :
We are looking for a highly experienced Solaris Migration Engineer to support the transformation of large, complex legacy Solaris environments into modern cloud-based platforms using AWS and Stromasys (CHARON) SPARC emulation. This role is remote-first but requires on-site presence during major cutovers, migration weekends and outage windows.
You will lead discovery, remediation, tooling development, migration execution and post-migration validation for mission-critical workloads. The ideal engineer has deep Solaris knowledge, proven migration delivery experience, and the discipline required to execute high-risk go-live events.
Key Responsibilities :
Migration Leadership & Execution
Lead end-to-end Solaris migration activities from physical SPARC hardware to AWS-backed Stromasys CHARON environments.
Perform on-site activities only when required for physical validation, data sync, cutover, or hardware assessments.
Execute migrations during weekend schedules, planned outages and critical change windows.
Runbooks, Tooling & Documentation
Create, maintain and own highly detailed migration runbooks, including:
Pre-migration checks
Data sync procedures
Cutover steps
Back-out/rollback plans
Validation & smoke testing
Develop and refine migration tooling, automation scripts and utilities to streamline repetitive tasks.
Technical Delivery
Conduct deep-dive discovery and assessment of legacy Solaris workloads.
Identify and remediate blockers such as OS constraints, obsolete libraries, storage differences and compatibility issues.
Work with cloud, network, storage and architecture teams to design end-to-end target-state solutions.
Validate performance and behaviour of workloads inside Stromasys CHARON emulation on AWS.
Ensure security, resilience, compliance and operational readiness for all migrated services.
Experience Required :
Solaris Expertise
Strong Solaris 10/11 administration, tuning, troubleshooting and legacy hardware knowledge (SPARC, storage subsystems, networking).
Experience supporting large-scale or business-critical Solaris estates.
Migration Delivery
Mandatory experience delivering Solaris migrations in structured, controlled change environments.
Proven track record executing migrations in weekend/outage windows, following strict runbooks.
Experience writing and owning end-to-end migration runbooks.
Cloud & Emulation
Experience migrating workloads into AWS (EC2, EBS, networking, security groups, IAM, landing zones).
Knowledge of or exposure to Stromasys CHARON SPARC emulation (highly desirable).
Understanding of cloud-hosted legacy system behaviour, performance baselining and risk mitigation.
Tooling & Automation
Strong scripting and automation experience (Bash/KSH, Python, Perl or similar).
Familiarity with migration frameworks, assessment tooling, and automation pipelines.
Soft Skills & Delivery
Ability to perform under pressure during high-risk cutovers.
Clear communicator who can explain issues to engineering, architecture and leadership teams.
Excellent documentation skills and disciplined approach to change control.
Additional Desirable Skills :
Experience with Oracle DB, Veritas, ZFS, Zones/LDOMs.
Familiarity with hybrid or multi-cloud migrations.
Experience working within MSP or enterprise environments.
