WHO WE ARE
Lockheed Martin is a global leader in aerospace, defense, and technology solutions, dedicated to pushing the boundaries of innovation and shaping the future of the industry. With a rich legacy of excellence and a commitment to delivering advanced capabilities to our customers, we are proud to be at the forefront of cutting-edge technology and engineering.
LM SPACE: WHAT WE'RE DOING
Ready to make a difference? Join a team where your network expertise will keep the sensors that watch the sky running flawlessly, give our warfighters the splitsecond advantage they need, and help keep the world safe. SBIRS and the NextGen GEO OPIR ground stations form the backbone of the UnitedStates missilewarning architecture. By delivering nearrealtime, highconfidence detection of ballistic missile launches and other hostile trajectories, these systems provide lifesaving early warning for the warfighter, enable rapid decisionmaking, and support cueing of defensive interceptors and commandandcontrol assets. Your work will directly protect troops, allies, and critical infrastructure worldwide.
THE WORK
Lockheed Martin is seeking a highly skilled level 4 Network Engineer with an active Secret clearance to work from our Boulder, CO, location.
This is a MID-SR CAREER (level 4) ROLE where candidates typically require 5+ years of professional experience and a BS degree.
The Overhead Persistent Infrared (OPIR) Infrastructure Team is seeking a Network Engineer to design, build, and sustain the groundstation platform that supports both SBIRS and the NextGen GEO OPIR ground stations. In this role you will work closely with software, security, and mission engineers to deliver ultrareliable, secure, and scalable groundsystems that enable continuous infrared surveillance and missilewarning capabilities for legacy and nextgeneration satellite constellations.
As Network Engineer you will:
Design and plan network communications systems.
Provide specifications and detailed schematics for network architecture.
Provide specific detailed information for hardware and software selection, implementation techniques and tools for the most efficient solution to meet business needs, including present and future capacity requirements.
Conduct testing of network design.
Maintain technical expertise in all areas of network and computer hardware and software interconnection and interfacing, such as routers, multiplexers, firewalls, hubs, bridges, gateways, etc. Evaluates and reports on new communications technologies to enhance capabilities of the network.
