Location (mandatory): Redmond, WA Client is seeking a Prototyping Engineer to join our Advanced Development Team. The ideal candidate is a self-starter who thrives in ambiguity, takes initiative to identify gaps in systems and processes, and builds solutions from the ground up. They are naturally curious and fine tinkering with a number of components. This role requires a versatile engineer with a working understanding of mechanical, electrical, and software systems who can smoothly integrate various subsystems into functional prototypes. The position involves hands-on building, working together with AI tools, debugging, and iterating on prototype hardware systems for next-generation AR/VR devices. A portion of the role will also involve developing, maintaining, and refining AI workflows that improve efficiency and increase impact.

Location (mandatory): Pittsburgh, PA Client is seeking a Temporary Systems Engineer to support day-to-day operations for research data collection environments. This person will help maintain, troubleshoot, and improve the hardware, software, and processes used to collect data for internal teams. The role involves working across multiple projects, coordinating with people from various disciplines (electrical, software, research, etc.), and ensuring systems stay running smoothly during active data collection sessions. This is a hands-on operational role — you won't be building systems from scratch, but you'll need to understand how they work well enough to keep them running, fix problems when they break, and improve processes over time. The work is onsite in Pittsburgh research/lab environments and requires strict adherence to data handling and participant privacy protocols.

Location (mandatory): Lexington, MA Group develops application-specific solid-state lasers and beam control and diagnostics for high-energy laser systems. Examples of research activities include creating cryogenic-laser-based illuminators for sensor applications, demonstrating wavelength and coherent laserbeam - combining techniques for scaling fiber amplifier and diode laser arrays to higher brightness, and developing a ground terminal for an advanced NASA laser experiment to a moonorbiting satellite. These activities span the range from demonstrating innovative laser devices in the laboratory to designing and field-testing complete optical systems.

Location (mandatory): Lexington, MA Mid-level Linux Systems Administrator candidate is needed in the Communication Systems to support the development of new technologies that enable worldwide networked operations for the military and other government agencies. The division addresses the needs of next-generation satellite, airborne, and terrestrial networks using its core expertise in radio frequency (RF), fiber and free-space optics, cyber security, network protocols and services, information operations, communications processing, and speech and language technologies. The division is extensively involved in field experimentation and measurement campaigns to verify algorithms and architectural concepts in operational environments.

Location (mandatory): Lexington, MA The Group specializes in advanced network and communications systems development, with a focus on tactical mobile, military airborne networks of the future.
