## Description

The Advanced Programs and Exploitation (APEX) team within Lockheed Martin Space is seeking a skilled software engineer to support space-based mission processing of OPIR data used for missile warning and defense programs.
In this position, you will develop and integrate mission processing applications and flight software that operate on space-based processing systems. You will work at the intersection of mission applications and the underlying flight software environment, developing software that must operate reliably within constrained, real-time, and mission-critical systems.
The selected candidate will be responsible for:

 * Designing, developing, and maintaining C++ software for space-based mission processing
 * Developing applications that interface with flight software and spacecraft processing infrastructure
 * Integrating mission applications with existing flight software frameworks and services
 * Developing and debugging software for embedded Linux and real-time operating systems
 * Working with inter-process communication, messaging, memory, and hardware interfaces
 * Troubleshooting and debugging software on embedded target hardware
 * Developing software that meets real-time, performance, reliability, and resource constraints
 * Participating in software architecture, design, code reviews, and technical documentation
 * Integrating software with other mission processing, payload, and spacecraft subsystems
 * Supporting software verification, qualification, and operational testing

This position is located in our offices in beautiful Boulder, Colorado.
