Cyber Security Administrator

Location: Denver, Colorado Compensation: Competitive base salary + package Environment: Smallsat Design and Manufacturing EVONA is working with a fast-growing space technology company that is building the next generation of satellite systems and expanding its operations across the United States. As the business scales its US footprint, its technology infrastructure needs to scale with it. That’s where you come in. We’re looking for a Cyber Security Administrator to take ownership of the secure IT and cyber environment supporting the company’s growing Denver operation. This isn’t a role where you’ll simply inherit a mature corporate environment and keep the lights on. You’ll be hands-on across infrastructure, cybersecurity, government cloud platforms and compliance, helping build and strengthen the systems that allow a rapidly growing space company to operate securely within highly regulated US government and aerospace environments. The opportunity You’ll become one of the key people responsible for the security and reliability of the US technology environment. Your world will span Microsoft GCC High, Azure Government and AWS GovCloud, alongside local infrastructure, networks, endpoints, identity and access management. One day you might be strengthening Conditional Access and privileged access controls. The next, you could be investigating suspicious activity, hardening infrastructure, preparing evidence for a compliance audit or improving the security architecture supporting the company’s continued US expansion. You’ll have genuine ownership and the opportunity to influence how the environment develops rather than simply following processes designed somewhere else. What You’ll Be Responsible For You’ll take ownership across: Microsoft GCC High, including Exchange Online, Teams, SharePoint, OneDrive, Intune and Entra IDAzure Government infrastructure, networking, storage, monitoring and securityAWS GovCloud, including IAM, networking, logging and security controlsWindows Server and Microsoft 365 environmentsFirewalls, VPNs, switches, routers, wireless networks and connectivityIdentity and access management, MFA, RBAC and privileged accessEndpoint security, EDR, encryption, patching and vulnerability managementSecurity monitoring, incident investigation, containment and remediationSystem hardening and security configurationBackup, disaster recovery and business continuityEmployee onboarding, offboarding, hardware and asset managementInfrastructure and security documentationAudit evidence, access reviews, inventories, logs and compliance records You’ll also help evaluate encryption technologies and protocols including AES, RSA, ECC and TLS/SSL, ensuring data-at-rest and data-in-transit is appropriately protected and aligned with FIPS 140-2/140-3 requirements. What We’re Looking For You’ll probably have 5+ years of experience across systems administration, infrastructure, IT operations or cybersecurity, ideally within an aerospace, defence, government or similarly regulated environment. You should be comfortable getting hands-on rather than operating purely at policy level. Experience across several of the following would be particularly valuable: Microsoft GCC High | Azure Government | AWS GovCloud | Entra ID | Active Directory | Intune | Microsoft Defender | Sentinel | EDR | IAM | Windows Server | Networking | Firewalls | VPNs | Vulnerability Management Exposure to CMMC, NIST 800-171, FedRAMP, ITAR, DFARS or comparable regulated environments would also be highly advantageous. Most importantly, we’re looking for someone who can solve problems, take ownership and operate effectively in a company moving quickly. Why apply? Because this is an opportunity to join during the build, not after everything has already been built. You’ll be working inside a fast-growing space company developing advanced satellite technology for commercial, scientific and government missions. You’ll have the autonomy to improve systems, strengthen security controls and influence how the US technology environment evolves as the organisation continues to scale. And because the company operates internationally, you’ll also collaborate with experienced engineering and technology teams across its global operations, with opportunities for occasional international travel. What's on offer? $120,000–$150,000 base salary, depending on experience Health insurance 401(k) matching Team performance-based bonus Professional development and progression opportunities International collaboration and occasional travel If you’re a Cyber Security Administrator who enjoys building, improving and securing complex environments — and you’d like to apply that experience to technology that ultimately operates in space — we’d like to hear from you.
