Solaris OS Application Expert (AWS Certified, Solaris to AWS Migration)

*Title - Solaris OS Application Expert (AWS Certified, Solaris to AWS Migration)*
*Client – Verizon, Irving TX*

*Role Summary*
We are seeking a Solaris OS Application Expert with active AWS certification and proven hands-on experience migrating Oracle Solaris environments to AWS. This specialist sits at the intersection of deep Unix systems engineering and cloud migration delivery — someone who understands Solaris architecture from Zones and LDOMs to SPARC-era application patterns, and knows how to translate those workloads into AWS-native equivalents. At 90 days, the expectation is a completed Solaris estate inventory, a validated migration wave plan, and at least one non-production Solaris workload running successfully in AWS.

*Key Responsibilities*
- Assess and document the existing Solaris estate — including Zones, Logical Domains (LDOMs), ZFS storage, and SPARC-dependent applications — to identify migration candidates and map technical dependencies.
- Design and execute Solaris-to-AWS migration strategies, selecting the appropriate path (rehost, re-platform, refactor) per workload based on application architecture and business SLAs.
- Configure and manage *AWS Application Migration Service (MGN)* and *AWS Database Migration Service (DMS)* to migrate Solaris-based workloads to Linux/AWS target environments.
- Collaborate with application owners to validate workload compatibility post-migration, resolve OS-level dependencies, and confirm functional parity on AWS.
- Develop *Ansible* and *shell scripting* automation for provisioning, patching, and configuration management of migrated workloads in AWS.
- Implement and enforce security baselines, host-level firewall rules, IAM policies, and compliance controls across migrated Linux/AWS environments.
- Troubleshoot complex Solaris and Linux system issues — performance, storage, networking, and application stability — during migration cutover and post-migration steady state.
- Produce detailed migration runbooks, test plans, and cutover procedures, and communicate wave-by-wave progress to technical leads and project stakeholders.

*Required Qualifications*
- *Hands-on Oracle Solaris administration experience in production environments, including Solaris 10/11, Zones, LDOMs, ZFS, and Oracle SPARC hardware.*
- *Demonstrated experience leading or substantially contributing to at least one Solaris-to-Linux or Solaris-to-AWS migration, including workload assessment, dependency mapping, and cutover execution.*
- *Active AWS certification required — AWS Certified Solutions Architect (Associate or Professional) or AWS Certified SysOps Administrator; Professional level strongly preferred.*
- *Proficiency with AWS migration services: AWS Application Migration Service (MGN), AWS Migration Hub, AWS DMS, EC2, VPC, S3, and IAM.*
- *Strong scripting skills in Bash, KSH, or Python; hands-on experience with Ansible and/or Puppet for OS automation at enterprise scale.*
- *Solid Red Hat Enterprise Linux (RHEL) administration skills — the common target OS in Solaris-to-cloud migrations — including patching, performance tuning, and storage management.*

*Preferred Qualifications*
- Experience with SPARC emulation tools (e.g., Stromasys Charon) for Solaris workloads that cannot be immediately re-platformed.
- Familiarity with Oracle Database or Oracle Middleware running on Solaris, and strategies for migrating those stacks to AWS RDS or EC2.
- Working knowledge of Terraform or AWS CloudFormation for infrastructure-as-code provisioning of target AWS environments.
- Experience with security and monitoring tooling in migration contexts: Tenable, Splunk, Tripwire, or equivalent.
- Background in large telecom or enterprise environments with strict uptime SLAs, ITIL change management, and ServiceNow-based governance workflows.
