Sales Engineer — Network & Security Solutions

New England | Upstate New York | Pennsylvania

FirstLight is seeking a Sales Engineer to support our Enterprise sales teams across New England, Upstate New York, and Pennsylvania. This role sits at the intersection of network infrastructure and cybersecurity, working across FirstLight's owned fiber network — Dark Fiber, Wavelength, Ethernet, SD-WAN — and our managed security services, including Managed Detection & Response (MDR), SOC-as-a-Service, XDR, and SIEM. We are looking for a technically versatile Sales Engineer who can design and position solutions across both domains, and who is looking to build long-term expertise at the convergence of network and security.
Why This Role

+ Work across two of the fastest-growing corners of enterprise tech: network transport (Dark Fiber, Wavelength, Ethernet, DIA) and cybersecurity (MDR, XDR, SIEM, SASE/SSE) — building fluency that's genuinely rare in the market.
