Working in our Chief Operating Office (COO)
Our COO Teams are the engine that powers Open Cosmos’ operations. This division brings together mission management, supply chain, and quality & product assurance to make sure every mission is delivered smoothly, reliably, and to the highest standards. They turn plans into action, keeping us efficient and mission-ready at all times.
We're looking for a 2nd Line IT Support Engineer to strengthen our IT operations and ensure our systems, offices, and people are supported with reliable, secure, high-performing technology.
What will you be doing?
This is a hands-on technical role — combining escalated user support, deeper infrastructure work, and continuous improvement. You’ll be the go-to point for complex issues across devices, networks, identity, and SaaS services, helping keep Open Cosmos running smoothly as we grow.
You will:
Own and resolve escalated issues across Windows, Linux, macOS, iOS/Android, networks, identity, and collaboration tools.
Troubleshoot, perform root-cause analysis, and implement corrective and preventative actions.
Meet SLAs and communicate clearly with users and stakeholders.
Administer Google Workspace, SSO/IAM, MFA and support our migration to M365 and Entra ID.
Manage endpoints using Intune/Jamf/MDM, including software packaging and secure baselines.
Support LAN/WLAN/VPN/DNS/DHCP/firewall changes and monitoring; liaise with providers as needed.
Manage the full device lifecycle — builds, replacements, RMAs and onboarding/offboarding.
Contribute to deployments and upgrades (office builds, Wi-Fi refresh, EDR rollouts, migrations).
Improve automation, self-service, reporting and monitoring through scripting and tooling.
Champion security best practice across patching, hardening, device compliance, and access controls.
What You’ll bring
Strong troubleshooting skills across Windows, Linux, macOS, mobile OS and SaaS platforms.
Demonstrable ability in administering M365, Entra ID, IAM, MFA/SSO, device compliance, EDR/AV and patching.
Comfortable with ITSM/ticketing, change control and documentation.
Familiarity with scripting/automation (PowerShell/Bash) is a plus.
Clear, confident communication skills — translating technical concepts for non-technical users.
