About us

Action1 is an autonomous patch management platform trusted by many Fortune 500 companies. Cloud-native, infinitely scalable, highly secure, and configurable in 5 minutes, it just works and is always free for the first 200 endpoints, with no functional limits.

Action1 is led by industry veterans Alex Vovk and Mike Walters, American entrepreneurs who founded Netwrix, which has grown into an industry-leading, multibillion-dollar cybersecurity company.

The Role

• Location: United States · Remote
• Working hours: U.S. Central Time (CT) business hours, starting at 8 or 9 a.m. CT, with after-hours support for critical incidents as needed.

We are hiring a Senior IT Engineer to strengthen our corporate IT systems and security. You will work directly with the Head of IT, share daily operations with our EU-based Systems Administrator, and take primary ownership of security operations and technical security controls across the organization.

In this small IT team, your ideas and technical judgment will help shape how we work. You will turn recurring problems into lasting improvements, build automation that the team relies on, and work with peers to share knowledge and learn from one another. You will own implementation, with the Head of IT providing direction and retaining program governance, policy approval, risk acceptance, and major incident oversight.

What you’ll do

• Manage Microsoft 365, Entra ID, Intune, and business applications, providing U.S. hours support and coordinating handoffs with our EU-based Systems Administrator.
• Resolve device compliance issues, restore employee access, and strengthen identity and endpoint security through hardening, access controls, and vulnerability remediation.
• Own infrastructure and security projects, turning recurring problems into lasting improvements.
• Build reliable automation and API integrations using Git and approved AI tools, with testing and independent validation.
• Triage security alerts, investigate and document incidents, and coordinate response and recovery with the Head of IT.
• Assess new and existing vendors and technology changes, review access requirements, and recommend safeguards for the Head of IT’s approval.
• Implement practical compliance controls, maintain audit evidence in Vanta, and resolve failed checks and technical findings.
• Maintain incident playbooks, test recovery procedures, and share knowledge across the IT team.

What we’re looking for

• 5+ years in systems administration, IT engineering, infrastructure, or a related role, with demonstrated ownership of complex technical work.
• Strong hands‑on experience with Microsoft 365, Entra ID, Intune, and Windows endpoints, supported by sound networking, DNS, and VPN fundamentals.
• Experience in a security operations center, either in‑house or with a managed security provider.
• Experience building and maintaining IT automation with tools such as PowerShell, Python, or Ansible, including API integrations.
• Experience using Git, branching, and pull requests to maintain scripts and automation.
• Hands‑on security operations experience, including alert triage, incident investigation, and response, using Microsoft Defender or comparable tools.
• Experience implementing security controls and supporting audits or evidence collection, with working knowledge of ISO 27001, SOC 2, or a comparable framework.
• Strong analytical and critical‑thinking skills: gather evidence, test assumptions, identify root causes, weigh security and operational trade‑offs, and verify results.
• Ability to balance employee support, incidents, and projects; communicate clearly; document decisions; and recognize when to escalate or seek approval.

Nice to have

• Infrastructure as code experience with Terraform.
• Experience with Vanta (or other GRC platforms), Microsoft Purview, and Datadog or Arctic Wolf (or SIEM tools.)
• AWS experience, particularly with VPN or backup services.
• Familiarity with GovRAMP or FedRAMP (NIST SP 800-53), CIS Benchmarks, and technical data protection requirements.

Benefits

• Fully remote work with flexibility to support your work-life balance.

• A collaborative environment that empowers you to own your domain and implement best practices.

• Stable income, benefits, flexible working hours, and opportunities for career advancement.

• Friendly, professional colleagues who are eager to support you and help you grow.
• Engaging challenges and opportunities to make a meaningful impact.
