Gcc Engineer Jobs in California (NOW HIRING)

Position Type: Full-Time, Exempt
Work Location: Oxnard, CA
Pay Info: $95,000 - $120,000 (DOE)
Systems Application & Technologies, Inc. (SA-TECH) is a progressive and well-established Department of Defense (DoD) contractor specializing in Range operations and maintenance (O&M); weapons testing; facilities management; aerial, ground and seaborne targets O&M; technical, logistics and other engineering support; systems integration; electronics and communications maintenance services; and a growing cybersecurity business. We are highly focused and, among other efforts, currently operate a dozen active test and/or training ranges for the Army, Air Force and Navy. Our 36-year heritage is founded on supporting complex and diverse DoD programs and we've developed a standout reputation for providing the highest quality services, superior workmanship and cost-effective results while achieving complete customer satisfaction.
As a U.S. defense contractor providing operations & maintenance, engineering, IT, and logistics services to DoD customers, we operate a modern, cloud-first Microsoft environment built on Microsoft 365 GCC and GCC High, backed by an established, well-documented cybersecurity program aligned to NIST SP 800-171 and CMMC Level 2.
We are currently looking to hire a Systems Administrator II to serve as the hands-on operational administrator of our two Microsoft government cloud tenants: an enterprise Microsoft 365 GCC tenant supporting corporate operations, and a Microsoft 365 GCC High enclave where Controlled Unclassified Information (CUI) is processed under NIST SP 800-171 and DFARS requirements. This is a full-time, on-site position at SA-TECH's Oxnard, CA Operations office.
This Level II role reports directly to the Director of IT. You enter as the Tier 2 technical escalation point, with an expected progression to Tier 3 within your first 12-18 months while you master the environment, including mentoring junior IT staff. You will execute administrative work under a mature governance model: changes go through change control, privileged access is just-in-time and audited, and the work you do is captured as assessment-ready evidence. If you take pride in doing systems administration the right way - documented, least-privilege, repeatable - you will recognize this environment as one built for you.
What you'll do (other duties may be added as needed):

• Microsoft 365 tenant administration (GCC and GCC High)
  • Administer core workloads across both tenants - Entra ID, Exchange Online, SharePoint Online, OneDrive, and Teams - including user and group lifecycle, licensing, and tenant configuration.
  • Maintain the separation between the enterprise GCC tenant and the GCC High CUI enclave, following SA-TECH's adopted boundary model and data-handling rules.
  • Support information-protection configurations (sensitivity labeling, DLP, sharing restrictions) in coordination with the Director of IT and the security operations function.
• Identity, access, and privileged administration
  • Operate a just-in-time, least-privilege administrative model with modern, phishing-resistant authentication - privileged work is time-bound, justified, and audited.
  • Administer identity and access management across both tenants: authentication policy, conditional access, and the credential lifecycle for users and administrators.
  • Manage service and special-purpose accounts according to documented configuration baselines and procedures.
  • Perform account provisioning, deprovisioning, and access changes tied to personnel actions, and support recurring account reconciliation reviews.
• Endpoint and device management
  • Administer Microsoft Intune for company devices - enrollment, configuration baselines, update regimens, and device lifecycle workflows across desktop and mobile platforms.
  • Follow SA-TECH's dedicated administrative workstation practices for privileged work, and help maintain the supporting configuration baselines.
  • Coordinate with the security operations function on endpoint protection; monitoring and independent review remain separated from this role by design.
• Automation, evidence, and operational discipline
  • Script and automate administrative work with PowerShell and Microsoft Graph, including against government cloud endpoints.
  • Execute changes through SA-TECH's change-control process: submit and implement approved change requests, keep configuration baselines current, and document what was done.
  • Capture and file evidence of administrative work (configuration exports, transcripts, screenshots) to support CMMC Level 2 assessment readiness - evidence capture is built into our procedures, not an afterthought.
  • Follow, improve, and help author standard operating procedures; propose better ways of doing things through the governance process rather than around it.
• Team support
  • Serve as the Tier 2 escalation point for junior IT staff and provide day-to-day mentoring, progressing to Tier 3 escalation authority.
  • Support Azure Government services connected to the enclave as the environment evolves.
  • Mentor more junior IT staff.

SA-TECH maintains deliberate separation of duties: governance and approvals, independent security oversight, and operational execution are distinct functions. This role owns execution - performing the administrative and configuration work in both tenants under that governance and oversight. You will have real responsibility and real authority to do the work - with clear limits, clear approvals, and an audit trail that protects you as much as the company.
This position is based full-time, on-site at SA-TECH's Oxnard, CA Operations office. Privileged administration and CUI-related work are performed on-site on SA-TECH-managed equipment in accordance with our data-handling and dedicated administrative workstation practices.
The annual base salary range for this position is $95,000 - $120,000. Actual base pay within this range is determined by job-related factors including relevant experience, skills, certifications, education, and internal equity, consistent with California pay-transparency requirements. SA-TECH also offers a comprehensive benefits package.
Work Conditions:

• Work will be performed in climate-controlled enclosed buildings.
• Work will include sitting, standing, walking, lifting and reaching.
• The typical work schedule is Monday - Friday, 7am - 4pm, with occasional planned after-hours maintenance windows scheduled through change control.
• You will be working in front of computer screens for most of the day.

Requirements
Required Education/Experience/Skills:

• High School Diploma or equivalent.
• Three years or more (3+) of hands-on systems administration experience in a Microsoft 365 / Entra ID environment.
• Working proficiency with Entra ID (users, groups, roles, Conditional Access), Exchange Online, SharePoint Online/OneDrive, Teams, and Intune.
• PowerShell scripting experience, including Microsoft Graph PowerShell or equivalent administrative automation.
• Understanding of multi-factor authentication, least-privilege administration, and role-based access control concepts.
• Strong documentation habits and the discipline to work within change control and standard operating procedures.
• Clear written and verbal communication, including the ability to explain technical work to non-technical stakeholders and, when needed, to assessors.
• Must possess valid US Drivers' license; must be able to be insured through SA-TECH's vehicle insurance policy while driving work/government/rental vehicles during working hours, and for the duration of your work employment.
• U.S. Citizenship required and you must be able to obtain a U.S. DoD Secret Security Clearance prior to start date and maintain a Secret clearance throughout employment.
• All candidates will be required to pass background screening to include SSN, Driver Record, and Criminal Background Investigation.

Preferred Qualifications:

• Experience administering Microsoft 365 GCC High and/or GCC, including familiarity with U.S. government cloud endpoints and their differences from commercial M365 would be very beneficial.
• Familiarity with NIST SP 800-171, CMMC Level 2, and DFARS 252.204-7012 obligations in a defense-contractor setting is a plus.
• Experience implementing privileged-access management, phishing-resistant MFA, or dedicated administrative workstation patterns in Microsoft environments would be very helpful.
• Experience supporting compliance assessments or audits (evidence gathering, walkthroughs, interviews) would be beneficial.
• Relevant certifications such as CompTIA Security+, MD-102, MS-102, SC-300, or AZ-104 are preferred.
• Experience with Azure (Azure Government preferred), Microsoft Purview, or Defender-family security tooling is a big plus.
• Prior DoD or federal IT experience - hands-on IT or technical work performed for, or in direct support of, DoD or other federal components (uniformed service, government civilian, or contractor) is an added advantage.
• Formal education - an associate's or bachelor's degree in information technology, computer science, cybersecurity, or a related field, or equivalent professional experience or military technical training is preferred.
• Clearance eligibility - the ability to obtain and maintain a U.S. security clearance should future contract requirements direct it; an active or previously held DoD security clearance is a plus.
