About the role

CACI is hiring an Embedded Software Development Engineer to design and develop embedded flight software (FSW) for CO2, H2O and gas analyzer sensor controllers supporting the next-generation spacesuit, Human Landing System (lunar lander) and the Artemis Program at NASA Johnson Space Center. The work covers prototyping, requirements, design, development, test, verification, integration and certification, plus unit test execution. The position is full time, based in Houston, with up to 10% continental US travel.

Key responsibilities

• Design and develop embedded flight software to control CO2, H2O and gas analyzer sensors.
• Create unit tests from self-developed test plans using the UT-Assert framework and Gcov, covering C code structurally and functionally.
• Evaluate unit test results (pass/fail, path coverage, loop boundaries, MC/DC) and troubleshoot failed tests.
• Perform C code reviews, collaborate on test issues, and run regression testing.
• Develop and maintain test plans, test cases and scripts, and execute manual and automated tests.
• Track defects with issue tracking tools and work with developers to resolve them.
• Perform systems engineering for requirements, interfaces, design and performance analysis, and integrate and test software/hardware in avionics test beds and flight certification environments.
• Collaborate with engineering teams and contractors across NASA programs and follow JSC standard software process practices.

Required profile

• U.S. citizen or permanent resident.
• B.S. in Aerospace, Electrical, Software, Computer or Systems Engineering, Computer Science, Biomedical Engineering or a related discipline.
• At least three years of embedded software development experience; more is highly valued.
• Significant experience across the entire software life cycle, with strong communication skills and ability to manage multiple priorities with little supervision.
• Desired: M.S. degree, aerospace systems experience, and experience in human-rated space vehicle software.

Required skills

• Strong C programming and Linux development experience.
• C/C++ unit tests with a framework such as Google Test (gTEST), UT-Assert or CppUnit.
• Embedded firmware for microcontrollers.
• Preferred: GitLab and Git, Python, bus protocols (RS-485, RS-422, RS-232, LVDS, 1553, USB, Ethernet), NASA Core Flight Software, Jira, Agile/Scrum, CMMI Level 3, and automated testing.

What we offer

• Proposed pay range of $76,000 - $155,700 USD, depending on experience, skills and contract terms.
• Healthcare, wellness, financial, retirement, family support, continuing education and time off benefits.
