Senior Software Engineer

Salary: $116000 - 249000 per year Requirements: We require a bachelors degree in Computer Engineering, Computer Science, Electrical Engineering, or a related discipline with at least 6 years of relevant experience, or a graduate degree with at least 4 years of related experience; in lieu of a degree, we require at least 10 years of relevant experience. We look for experience developing software for aerospace, space, avionics, or similarly complex embedded systems. We look for experience building STE, EGSE, bench, or lab support software that controls hardware, automates engineering work, or interfaces with electronics and instrumentation. We require experience in embedded software development using C/C++ and scripting languages such as Python for integration, control, or automation. We require experience with real-time operating systems such as VxWorks, FreeRTOS, RTLinux, QNX, or similar platforms. We require experience integrating and troubleshooting software at the hardware/software boundary. We require experience with communication and control protocols such as SpaceWire, MIL-STD-1553, RS-422, Ethernet, CAN, UART, SPI, I2C, or equivalent interfaces. We look for experience creating scripted command, control, or checkout sequences for subsystems, support equipment, or integration environments. We require the ability to obtain a U.S. Security Clearance. Preferred: ability to interpret engineering drawings, interface documents, and electrical schematics. Preferred: familiarity with STIG and cyber hardening practices. Preferred: knowledge of the space domain, including payload integration, command and telemetry flows, mission operations concepts, or space vehicle development environments. Preferred: experience with command and control software, embedded controllers, processor-based electronics, or subsystem management applications. Preferred: familiarity with motors, servo controllers, shutters, gimbals, actuators, focus mechanisms, and related electromechanical devices. Preferred: experience with imaging payloads, visible cameras, IR detectors, optical systems, or sensor processing applications. Preferred: experience developing software for microcontrollers, board support packages, device drivers, or low-level hardware interfaces. Preferred: familiarity with MATLAB/Simulink, LabVIEW, COSMOS, or similar engineering and integration toolchains. Preferred: experience with DevOps and configuration management tools such as Git, Bitbucket, Jenkins, Jira, and Confluence. Preferred: experience supporting integration, verification, qualification, or environmental test campaigns in aerospace or defense settings. Preferred: familiarity with open architecture standards, model-based systems engineering tools, or secure software development practices. Responsibilities: We lead the design, development, and implementation of software for STE and EGSE used to command, monitor, configure, and support integration of space-based payloads and embedded subsystems. We develop application software, control software, service utilities, and scripted workflows for lab, integration, and qualification environments. We design and implement embedded real-time software for subsystem control, device interfaces, telemetry processing, command handling, and hardware/software integration. We develop software that interfaces with lab instrumentation, processors, controllers, and custom electronics for checkout, diagnostics, and engineering use cases. We define software architecture, requirements allocation, interface behavior, and design artifacts for both ground-support and embedded software components. We collaborate with systems, electrical, mechanical, and test engineering teams to integrate payloads, controllers, sensors, and support equipment into unified operational workflows. We support software bring-up, hardware integration, low-level debugging, root cause analysis, and issue resolution across embedded and support-equipment environments. We contribute to software documentation, code reviews, development process execution, and technical planning across cost, schedule, and scope. We lead small technical teams and provide guidance on implementation choices, reuse, maintainability, and lifecycle execution. We support the transition from development into integration, verification, and mission or production readiness activities. Technologies: BitBucket Confluence DevOps Embedded Ethernet FreeRTOS Git Hardware Support JIRA Jenkins Matlab Python Security C++ More: We are L3Harris, a Trusted Disruptor in defense technology, delivering end-to-end solutions across the space, air, land, sea, and cyber domains in support of national security. We foster an inclusive, engaging environment that encourages professional growth, employee empowerment, community commitment, and a strong work-life balance. This role is based in Rochester, NY and follows a 9/80 schedule. We offer a competitive compensation package and benefits that may include health and dis
