Build, support, and improve the security platforms that protect our clients.

Tusker is seeking a hands-on engineer with at least three years of technical experience who can independently troubleshoot complex issues, safely administer production platforms, and recognize when escalation is needed. In this role, you will help keep our customer-facing security technologies reliable, secure, and ready to scale—while continuing to expand your engineering and cybersecurity expertise.

What You’ll Do

• Administer, monitor, maintain, and support customer-facing security platforms and operational technologies.
• Handle Tier 3 escalations by analyzing logs, configurations, connectivity, integrations, and system behavior to identify root causes and restore service.
• Independently resolve technical issues within established procedures and escalate architectural, unfamiliar, or business-critical matters appropriately.
• Assist with planning and testing platform upgrades, patches, and releases while executing and validating approved production changes and scheduled maintenance.
• Support new-client onboarding by configuring and validating platform components, agents, policies, connectivity, and integrations.
• Identify opportunities to improve reliability, scalability, efficiency, and supportability through better processes, scripts, tools, and automation.
• Assist with investigating and resolving platform outages and service-impacting incidents, working with internal teams and vendors to restore service.
• Maintain accurate runbooks, technical procedures, troubleshooting notes, standards, and platform documentation.
• Collaborate with the SOC, Service Desk, Client Experience Managers, IT Operations, vendors, senior engineers, and architects.
• Apply a security-first mindset and follow change management, access control, and operational governance requirements.

What You Bring

• 3+ years of professional experience in IT, cybersecurity, systems administration, platform engineering, technical support, or a related discipline.
• Experience troubleshooting and supporting enterprise technology environments beyond traditional Tier 1 or Tier 2 responsibilities.
• Strong Windows knowledge and a solid understanding of TCP/IP, DNS, DHCP, firewalls, routing, and network troubleshooting.
• Familiarity with Microsoft 365, Azure/Entra ID, Active Directory, endpoint security, identity, access controls, and security best practices.
• A methodical, analytical approach to complex technical problems.
• The ability to work independently, manage competing priorities, and exercise sound judgment about when to seek guidance.
• Strong attention to detail when making production changes or performing platform maintenance.
• Clear written and verbal communication, including the ability to explain technical findings to technical and non-technical audiences.
• A commitment to continuous learning, accountability, and developing deeper ownership of assigned technologies.

Preferred Qualifications

• Experience in an MSSP, MSP, cybersecurity organization, or enterprise technology environment
• Experience with EDR/XDR, SIEM, RMM, vulnerability management, email security, backup, or disaster recovery platforms
• Knowledge of Windows Server, Active Directory, Microsoft 365, Entra ID, and cloud or hybrid environments
• Experience with PowerShell, automation, APIs, platform integrations, or enterprise monitoring tools
• An associate or bachelor’s degree in IT, Cybersecurity, Computer Science, or a related field; equivalent professional experience is accepted
• Relevant Microsoft, CompTIA Network+, Security+, CySA+, or vendor-specific certifications
• Why This Role Matters
• You will play a key role in maintaining the reliability, security, and operational readiness of the technologies behind Tusker’s managed security services. You will have meaningful ownership, direct impact on client service, and a defined path to deepen your platform expertise and engineering responsibilities with support from senior engineers and architects.
• Ready to Make an Impact?
• If you are a curious, accountable engineer who enjoys solving complex problems and is ready to take ownership beyond traditional support work, we encourage you to apply.
