Unit Test Software Engineer, NASA Orion Spacecraft

CACI is looking for Unit Test Software Engineers to work on the Orion spacecraft’s Flight Software (FSW) used in NASA’s Artemis program to carry astronauts to the Moon and back. This position involves implementing, executing, and evaluating results of the Orion spacecraft FSW unit test cases across various FSW domains.

Orion is NASA’s next generation crewed spacecraft that will rendezvous with the Gateway space station in Lunar orbit. Gateway is intended to serve as a communication hub, science laboratory, and short-term habitation to stage astronauts transferring to or returning from the lunar surface. Gateway will also be used as a testbed to develop technologies needed for crewed missions to Mars.

• Review test plans with the Orion FSW prime contractor FSW Subject Matter Experts (SMEs).
• Create thorough unit tests from test plans using Google Test, Gcov, and gMock that test C/C++ classes both structurally and functionally.
• Evaluate unit test case results including pass/fail results with path coverage, loop boundary limits, and Modified Condition/Decision Coverage (MC/DC).
• Troubleshoot issues with failed test cases.
• Perform C/C++ code reviews to spot errors in the code logic.
• Collaborate with prime contractor SMEs for resolving unit test case issues.

This work takes place at the Orion FSW prime contractor’s facilities in Houston, TX, a highly stimulating and dynamic environment that is critical in human space flight and the space exploration initiative. However, the position can be performed remotely.

• Must be a U.S. Citizen.
• B.S. in Aerospace, Electrical, Computer or Systems Engineering, Computer Science, or related disciplines required.
• Experience programming in C++.
• Experience with C++ software unit testing in Aerospace or other industries, e.g., commercial software, oil and gas, petrochemical, etc. Any related intern or co-op experience is valued.
• Must be flexible, open to new challenges in a dynamic environment, and possess strong technical expertise combined with strong verbal and written communication skills.
• Ability to manage multiple priorities with little supervision.
• Must be a highly responsible, team-oriented individual with strong work ethic.
• Must have highly developed coordination and organization skills.

Desired:

• M.S. in Aerospace, Electrical, Computer, Systems, or Software Engineering, Computer Science, or related disciplines required.
• Experience debugging unit test issues including determining the difference between test framework problems created by the tester and problems with the flight code.
• Experience with Google Test, Gcov, and gMock.
• Experience programming in Python.
• Experience with Agile software development methodology.
• Experience with software configuration management tools such as Git and Subversion.
• Experience in avionics and flight software development and/or testing for human-rated space vehicle or satellites.
• Familiarity with NASA's Orion spacecraft.
• Experience or knowledge of space vehicle systems, e.g., avionics, command and telemetry, command and control, timeline/vehicle management, service module control, systems management, crew life support, displays, power, propulsion, thermal, guidance, navigation and control, communications and tracking, NASA Docking System, etc.
