Apollo's primary markets include state and local government, K-12 and higher education, and mid-market enterprises, with deep specialization in election security.

- Design secure solutions across cybersecurity, networking, and cloud technologies, balancing client business needs with sound security architecture.

- Perform configuration, installation, enablement, and maintenance of security products and services.

- Research and implement solutions to technical problems, including design changes to client environments.

- Maintain deployed security, network, and cloud environments to ensure continued operational performance.

- Perform network administration tasks, including client trouble tickets and design changes.

- Monitor security events and investigate suspicious activities.

- Partner with SOC Analysts to develop and refine SIEM correlation rules and custom detection methods.

- Leverage platforms and services to gather data, generate reports, and support clients and other departments with analysis.

- Participate in the successful completion of small to medium-sized projects.

- Prepare and document standard operating procedures and protocols for security operations.

- Collaborate across teams and departments to address security concerns.

Qualifications

- Required - Experience in cybersecurity, network administration, or systems administration, with at least some of that time in a hands-on engineering capacity. - Demonstrated experience implementing, and managing security and/or network technologies in production - Experience with common security tools and technologies (e.g., firewalls, IPS/IDS, SIEM, EDR/MDR). - Scripting or automation experience (e.g., PowerShell, Bash, Python). - Strong analytical and troubleshooting skills, with the ability to manage multiple client priorities in a fast-paced managed services environment. - Clear written and verbal communication skills, including the ability to document designs and explain technical concepts to clients

- Preferred - Experience in security engineering or architecture - Product expertise with network security providers such as Fortinet or Sophos (and exposure to Palo Alto, Cisco). - Proficiency with cloud platforms M365, Azure, GCP, or AWS, including cloud-native security services. - Identity and access management best-practice expertise. - Experience with one or more SIEM platforms (e.g., Stellar Cyber, Splunk, LogRhythm, Elastic, or Azure Sentinel). - Experience with vulnerability management and asset visibility tooling (e.g., Tenable, Sevco, or similar). - Familiarity with cloud identity and access management across platforms such as Microsoft Entra ID and Google Workspace, including SSO and MFA configuration. - Exposure to managed services or MSSP delivery models, including multi-tenant operations and client facing engagement.

Expectations:

- At 30 days: - Complete onboarding to Apollo's core tool stack, internal systems, and the Aegis platform - Shadow at least two active client environments to build context on Apollo's customer base, deployment patterns, and the practical realities of what you'll be supporting and building - Meet every member of the engineering and SOC teams; understand who owns what and how work flows between functions

- Within 90 days: - Own at least one scoped technical workstream independently with minimal hand-holding - Demonstrate working knowledge of the threat landscape relevant to Apollo's SLED and SMB clients; be able to speak to common attack surfaces and how Aegis addresses them - Actively contribute to peer reviews, architecture discussions, or post-incident reviews - Identify one process, gap, or tooling opportunity worth improving and bring a recommendation to your manager

- By 180 days: - Serve client-facing work without requiring senior oversight on standard complexity - Build and maintain relationships with at least two cross-functional peers (SOC, Sales Engineering, or PM)
