IT System Administrator (1099 Contract)
Red Cell Partners is seeking an experienced IT System Administrator to support and maintain the infrastructure that keeps our cloud environments, identity systems, and end-user services running reliably and securely. This is a 1099 independent contractor engagement supporting a fast-moving team operating across commercial and government cloud environments.
As the IT System Administrator, you will own day-to-day administration across our multi-cloud footprint—spanning AWS and Microsoft Azure—as well as our Microsoft 365 collaboration and identity stack. You will be the hands-on technical resource responsible for provisioning, monitoring, hardening, and troubleshooting the systems our workforce depends on, while helping ensure our environment meets the security and compliance expectations of a company operating in Department of War (DoW) mission spaces.
This role is well suited to a self-directed contractor who is comfortable working independently, documenting their work clearly, and balancing routine operational tasks with project-based infrastructure improvements. This is a 1099 contract opportunity, with full-time hours.
Responsibilities include administering, monitoring, and maintaining workloads across AWS and Microsoft Azure, managing resource provisioning, cost visibility, tagging, and baseline security configuration across both cloud platforms. The role also involves supporting hybrid and cloud-native architectures, troubleshooting connectivity, performance, and availability issues, and integrating with an interdisciplinary team of experts in optimization and simulation to design, build, and optimize models that deliver high-quality, real-world insights.
Additionally, the IT System Administrator will administer the Microsoft 365 tenant, including Entra ID (Azure AD), Exchange Online, SharePoint, Teams, and related services. They will manage user lifecycle (provisioning/deprovisioning), licensing, group and role assignments, and conditional access policies, as well as support mail flow, security baselines, and collaboration platform configuration. The role also includes performing routine system administration, patching, monitoring, and maintenance across endpoints and cloud-hosted systems, responding to and resolving escalated infrastructure and end-user support issues, and maintaining accurate documentation, runbooks, and configuration records.
Required qualifications include 2–5 years of experience in IT support, IT engineering, or a similar role, with strong hands-on experience with end-user hardware and software support, Windows and/or macOS environments, SaaS and cloud-based tools, and experience working with ticketing systems and/or external IT vendors or MSPs. Strong organizational skills and attention to detail, clear communication skills, and a customer service mindset are essential. The candidate should be self-motivated and adaptable in a fast-paced startup environment, willing to take the initiative to learn new systems or technologies as needed, and reliable and trustworthy, especially when handling sensitive data or system access.
Preferred qualifications include experience supporting remote or hybrid teams, familiarity with identity, device, or license management tools (MDM, SSO, endpoint management), exposure to regulated or security-conscious environments (government, defense, healthcare, finance), and an interest in growing into more advanced IT operations or security responsibilities over time.
