Senior Network Engineer

About Black Mountain Dynamics
Black Mountain Dynamics secures, deploys, and supports IT infrastructure for startups, venture-backed companies, VIP clients 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.
Role Overview
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.
Primary Mission
Own the hardest problems, lead escalations and security response, and raise the technical standard across the Service Delivery organization.
Core Responsibilities
Advanced Escalations & Technical Ownership
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.
Network Engineering & Infrastructure
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.
Security, Incident Response & Risk Reduction
Coordinate incident response for critical security events, including stabilization, communication, containment, remediation, documentation, and follow-up prevention.
Use tools such as SentinelOne, firewall logs, SIEM/monitoring platforms, and ticket history to investigate security events.
Conduct threat analysis, vulnerability review, and root cause analysis for security-impacting incidents.
Identify systemic risks and recommend preventative controls, process improvements, or architecture changes.
Ensure secure execution through least privilege, documented change plans, rollback paths, and proper stakeholder communication.
Identity, SaaS & Endpoint Escalation
Provide senior support for JumpCloud, Microsoft 365, Google Workspace, MDM, SSO/SAML, SCIM, JIT provisioning, and related identity workflows.
Troubleshoot SAML assertion errors, certificate issues, attribute mapping, provisioning failures, and authentication problems.
Support Apple Business Manager / DEP, device enrollment, encryption enforcement, and endpoint management issues.
Validate and guide Tier 2 work involving identity integrations, policy changes, access control, and endpoint security.
Ensure identity and endpoint standards are documented and repeatable.
NOC Escalation & Operational Response
Serve as a senior escalation point for NOC issues, after-hours escalations, monitoring alerts, and PagerDuty events.
Help distinguish routine alert/maintenance response from true emergency or client-initiated urgent work.
Correlate alerts across monitoring systems, firewalls, switches, endpoints, ISPs, and client impact.
Identify noisy alerts, monitoring gaps, false positives, and recurring operational problems.
Improve alert handling procedures, escalation paths, and NOC documentation.
Documentation, Standards & Process Improvement
Create and maintain technical documentation in Hudu, including network diagrams, troubleshooting guides, escalation procedures, client environment details, and post-incident notes.
Produce RCA summaries, incident reports, technical recommendations, and standards documentation.
Build repeatable SOPs and playbooks for complex issues that should become easier for Tier 1 and Tier 2 over time.
Own continuous improvement across engineering processes, security practices, monitoring standards, documentation maturity, escalation quality, and infrastructure reliability.
Partner with the Service Delivery Manager and Technical Project Manager to ensure project handoffs into operations are clean and supportable.
Mentorship & Technical Leadership
Mentor Tier 1 and Tier 2 engineers through escalation review, troubleshooting approach, documentation quality, client communication, and repeatable technical standards.
Review escalation packets and coach the team on what good technical handoff looks like.
Confirm readiness or proficiency for Tier 2 engineers as they ramp into tools such as HaloPSA, JumpCloud, PRTG, SentinelOne, Hudu, SSO, firewall troubleshooting, and NOC workflows.
Raise the team’s technical skill level through coaching, documentation, shadowing, and standards development.
Model BMX core values and white-glove service in both internal and client-facing work.
Culture & Technical Leadership Expectations
Lead with ownership and blameless problem solving during escalations, incidents, and post-incident reviews.
Stabilize first, then drive root cause, prevention, documentation, and standards improvement.
Communicate clearly before surprises occur, especially during complex incidents, client-impacting changes, or security events.
Make safe, security-first decisions using least privilege, documented plans, peer review where appropriate, and rollback paths.
Coach Tier 1 and Tier 2 engineers through the “why,” not just the fix.
Convert complex or recurring work into SOPs, diagrams, playbooks, automation, or monitoring improvements.
Maintain a high standard of professionalism, urgency, and calm execution during ambiguity or pressure.
Look for service, security, and infrastructure improvement opportunities that create long-term client value.
Accountable For
