About The Position

The Senior Network Engineer is the technical owner for the design, implementation, monitoring, and ongoing support of the company’s hybrid network environment, and leads the network function, including cloud network operations. The role provides secure, reliable connectivity across offices, retail locations, warehouse facilities, AWS and Azure cloud environments, and remote users. It covers Cisco and Meraki switching and wireless infrastructure, Palo Alto firewalls, and VPN services. A key objective is modernizing cloud connectivity by replacing the company’s dependency on Cisco cloud services routers with cloud-native technologies for Azure-to-AWS and cloud-to-site communication. Working independently and with Infrastructure, Security, DevOps, application teams, business stakeholders, and vendors, the engineer establishes standards, leads network projects, resolves complex incidents, and improves network performance, resilience, security, and scalability. The position provides technical guidance and mentoring to other engineers and participates in an on-call rotation for critical network services. The position is primarily performed from a home office or other approved remote work environment. Regular travel to customer sites, meetings, or other business locations is required (10–25%). Duties primarily involve prolonged sitting, computer work, and communication by phone and video conference. Occasional lifting of office materials or equipment up to 15 pounds may be required. The salary range is $115,800 to $130,250 annually, and the position is eligible for an annual discretionary bonus. Benefits include competitive wages; healthcare, including medical, dental, vision, prescription drugs, and FSAs; a 401(k) plan; paid time off and holidays; paid parental leave; life and disability insurance; an Employee Assistance Program; and professional development and tuition assistance.
