Senior Network Engineer

Department: Service Delivery
Role Type: Remote with client-site support as needed
Reports To: Service Delivery Manager

Black Mountain Dynamics secures, deploys, and supports IT infrastructure for startups, venture-backed companies, and growing organizations. We partner with innovative clients to design, deploy, and operate reliable network, security, identity, and endpoint environments that support critical business systems.

Our approach emphasizes security, performance, documentation, operational resilience, and high-touch service delivery. As our client base grows, we are expanding our engineering team to support increasingly complex customer environments across multiple locations, platforms, and technical stacks.

We are seeking a Senior Network Engineer who is passionate about networking, cybersecurity, infrastructure, and solving complex technical problems. This role serves as the senior escalation point for the Service Delivery team and owns the most complex issues across network, security, identity, endpoint, SaaS, monitoring, and client infrastructure environments.

This role combines hands-on technical engineering with service leadership. You will lead advanced troubleshooting, guide major incident response, support project execution, mentor Tier 1 and Tier 2 engineers, improve documentation and standards, and provide trusted technical guidance to clients and internal stakeholders.

The Tier 3 Engineer is expected to raise the technical bar across the team by creating repeatable processes, improving operational visibility, reducing recurring incidents, and ensuring that technical work is completed securely, cleanly, and with strong documentation.

Success in this role requires calm ownership, technical judgment, and cultural leadership. Tier 3 engineers are expected to model blameless problem solving, create leverage through documentation and standards, communicate clearly during pressure, and improve the team’s ability to prevent repeat issues.

Own the hardest problems, lead escalations and security response, and raise the technical standard across the Service Delivery organization.

• Own highest-complexity escalations across network, security, identity, endpoint, SaaS, monitoring, and infrastructure issues.

• Lead troubleshooting for complex, recurring, architectural, or security-sensitive issues, ensuring the team understands the root cause, client impact, resolution path, and prevention opportunity.

• Support Tier 2 engineers when tickets require deeper analysis, senior validation, architectural review, or risk assessment.

• Provide clear escalation guidance, recommended next steps, and technical decision-making under pressure.

• Ensure complex tickets include strong documentation, impact analysis, troubleshooting history, and next-action clarity.

• Design, implement, troubleshoot, and support LAN, WAN, WLAN, firewall, VPN, VLAN, NAT/PAT, and segmentation environments.

• Configure, install, and maintain routers, switches, firewalls, wireless access points, and related network infrastructure.

• Lead network deployments, client buildouts, site changes, and infrastructure modernization efforts.

• Use monitoring platforms such as PRTG, Unimus, and related tools to identify patterns, bottlenecks, outages, false positives, and repeat issues.

• Review firewall policies, logs, routing, wireless health, ISP issues, and client-impacting network events.

• Provide senior review and sign-off for firewall changes, network changes, and higher-risk technical work.
