Top Engineering Jobs

Lead mission integration and test activities: develop and maintain ICDs, mission CONOPS, simulator requirements, and mission-level verification and test plans. Support launch rehearsals, operations, post-launch integration, and cross-functional coordination to ensure end-to-end space-to-ground compatibility and mission readiness.

Early-career systems engineer responsible for developing, maintaining, verifying, and communicating system architecture and requirements for missions, segments, elements, and subsystems. Works with multidisciplinary teams through program lifecycle, supports gate reviews, coordinates verification and I&T, uses MBSE and requirements tools, mentors junior engineers, presents to stakeholders, and must hold an active Top Secret clearance with TS/SCI polygraph eligibility.

Lead design, development, integration, test, and production of high-reliability embedded and mixed-signal CCAs for military avionics. Develop FPGA/processor-based architectures, perform requirements and trade studies, execute test plans, support prototyping and LRIP/FRP, and participate in business capture and production sustainment.

Design, write, integrate, and test prototype and low-volume cutting-edge software (algorithms, platforms, embedded/real-time systems) using C++ on Linux. Collaborate across teams in a fast-paced R&D environment (FAST Labs) supporting defense systems. Requires on-site work in Merrimack, NH and an active Secret DoW clearance with ability to obtain Top Secret.

Lead multi-disciplinary teams to architect high-performance electro-optical space segments. Develop concept designs, lead trade studies, define mission models and performance analyses, engage suppliers, ensure DFx and mission assurance, support capture and transition to program execution, mentor technical leaders, and serve as primary customer technical contact for classified defense/IC space programs.

Perform systems engineering on defense electronic systems across design, modeling, integration, test, fielding, and support. Collaborate with software, hardware, and test teams on SIGINT, radar warning, and electronic attack systems. Requires a bachelor's degree, 2+ years' related experience, and ability to obtain Secret clearance.

Lead systems engineering for safety-critical avionics and electronic control systems: develop and manage system/hardware/software requirements, design architectures, define interfaces, perform system integration, verification and validation, produce technical documentation, and support proposals and program activities.

Implement and activate network services per DISA standards: coordinate customers and vendors, configure devices using configlets, validate DISN/databases, perform IT&A testing, manage TSOs/Service Orders, monitor post-change impacts, troubleshoot issues, and document solutions while liaising with stakeholders and DISA project managers.

Lead development of high-fidelity 6-DOF missile/rocket dynamics simulations for the LGM-35A Sentinel. Design, code, test, and validate MS&A tools, collaborate with cross-functional teams on propulsion and guidance, and produce technical briefings and reports for program leadership.

Develop, test, and integrate cutting-edge software for defense-related systems. Collaborate with cross-functional teams to design applications in C++, Python, and MATLAB; work with cloud-native, containerization, RTOS, FPGA/GPU/embedded SoC hardware, DevSecOps/CI-CD practices, and communication protocols (UART/I2C/SPI/CAN). Participate in agile prototyping and deliver low-latency, real-time software for RF, radar, EO/IR, EW, and software-defined radio systems. Role is full-time onsite in Merrimack, NH.
