About The Position

L3Harris Space and Mission Systems are seeking a Space Software Engineer to develop software for Specialized Test Equipment (STE), Electrical Ground Support Equipment (EGSE), and embedded real-time systems supporting complex space-based payloads and subsystem integration. This role is centered on software development for ground and lab environments that interface with flight-like hardware, while also contributing to embedded software design and implementation for real-time control, command and telemetry handling, and subsystem integration.

Requirements

Bachelor's Degree in Computer Engineering, Computer Science, Electrical Engineering, or related field and minimum 6 years of prior relevant experience. Graduate Degree and a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years of prior related experience.
Experience developing software for aerospace, space, avionics, or other complex embedded systems.
Experience developing STE, EGSE, bench, or lab support software used to control hardware, automate engineering tasks, or interface with electronics and instrumentation.
Experience in embedded software development using C/C++ and scripting languages such as Python for integration, control, or automation tasks.
Experience with real-time operating systems such as VxWorks, FreeRTOS, RTLinux, QNX, or similar real-time platforms.
Experience integrating and debugging software at the hardware/software boundary.
Experience with communication and control interfaces such as SpaceWire, MIL-STD-1553, RS-422, Ethernet, CAN, UART, SPI, I2C, or similar protocols.
Experience developing scripted command, control, or checkout sequences for subsystems, support equipment, or integration environments.
Ability to obtain a U.S. Security Clearance.

Nice To Haves

Ability to read and interpret engineering drawings, interface documents, and electrical schematics.
Familiarity with STIG and Cyber hardening procedures.
Knowledge of the space domain, including payload integration, command and telemetry flows, mission operations concepts, or space vehicle development environments.
Experience with command and control software, embedded controllers, processor-based electronics, or subsystem management applications.
Familiarity with motors, servo controllers, shutters, gimbals, actuators, focus mechanisms, and related electromechanical devices.
Experience with imaging payloads, visible cameras, IR detectors, optical systems, or sensor processing applications.
Experience developing software for microcontrollers, board support packages, device drivers, or low-level hardware interfaces.
Familiarity with MATLAB/Simulink, LabVIEW, COSMOS, or similar engineering and integration toolchains.
Experience with DevOps and configuration management tools such as Git, Bitbucket, Jenkins, Jira, and Confluence.
Experience supporting integration, verification, qualification, or environmental test campaigns in aerospace or defense environments.
Familiarity with open architecture standards, model-based systems engineering tools, or secure software development practices.

Responsibilities

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.
Develop application software, control software, service utilities, and scripted workflows used in lab, integration, and qualification environments.
Design and implement embedded real-time software for subsystem control, device interfaces, telemetry processing, command handling, and hardware/software integration.
Develop software that interfaces with lab instrumentation, processors, controllers, and custom electronics in support of checkout, diagnostics, and engineering use cases.
Define software architecture, requirements allocation, interface behavior, and design artifacts for both ground-support and embedded software components.
Collaborate with systems, electrical, mechanical, and test engineers to integrate payloads, controllers, sensors, and support equipment into cohesive operational workflows.
Support software bring-up, hardware integration, low-level debugging, root cause analysis, and issue resolution across embedded and support-equipment environments.
Contribute to software documentation, code reviews, development process execution, and technical planning for cost, schedule, and scope.
Lead small technical teams and provide guidance on software implementation, reuse, maintainability, and lifecycle execution.
Support transition from development through integration, verification, and mission or production readiness activities.
