What are some common challenges faced by ECLSS system engineers when integrating life support systems into spacecraft designs?

ECLSS System Engineers often encounter challenges related to balancing strict mass, power, and volume constraints with the need for reliability and redundancy in life support systems. Integrating these complex systems requires close collaboration with propulsion, thermal, and avionics teams to ensure compatibility and overall mission safety. Additionally, engineers must stay updated with evolving NASA and international standards, which can impact design requirements and timelines. Addressing unexpected interactions between subsystems during testing is another frequent hurdle, requiring strong problem-solving skills and adaptability.

What are the key skills and qualifications needed to thrive as an ECLSS system engineer?

To thrive as an ECLSS System Engineer, you need a solid background in mechanical, chemical, or aerospace engineering, often with a relevant degree and experience in life support or spacecraft systems. Familiarity with modeling software (such as MATLAB or Simulink), systems integration tools, and industry standards like NASA's technical requirements is crucial. Strong problem-solving, collaboration, and communication skills help you work effectively within multidisciplinary teams and respond to complex challenges. These competencies ensure the safe, efficient design and operation of life support systems critical to human space missions.

What is an ECLSS system engineer?

An ECLSS System Engineer is a professional who specializes in the design, development, and maintenance of Environmental Control and Life Support Systems (ECLSS) used in spacecraft and space habitats. These systems are responsible for providing and maintaining safe and habitable conditions for astronauts by managing air, water, temperature, and waste. ECLSS System Engineers work on complex engineering challenges to ensure that life support systems function reliably in the harsh environment of space. Their responsibilities often include system integration, testing, troubleshooting, and continuous improvement of life support technologies.

What is the difference between Eclss System Engineer vs Eclss Software Engineer?

AspectEclss System EngineerEclss Software Engineer
CredentialsBachelor's in Engineering, certifications in systems or aerospaceBachelor's in Computer Science or Software Engineering, coding certifications
Work EnvironmentSystems integration, hardware and software coordination in aerospace projectsSoftware development, coding, testing in aerospace or defense sectors
Industry UsageDesigning and managing ECLSS systems in spacecraftDeveloping software components for ECLSS systems

The Eclss System Engineer focuses on integrating and managing environmental control and life support systems hardware and overall system performance. In contrast, the Eclss Software Engineer specializes in developing and testing the software components that control and monitor these systems. Both roles are essential in aerospace projects but differ mainly in their focus on hardware versus software development.

Position Introduction/Key Duties
Cimarron is seeking Software Test Engineers to support the verification, validation, and integration of software for the Axiom Space Commercial Space Station in Houston, TX. In this role, you will focus on software verification testing, hardware/software integration, and system-level test activities to ensure flight-critical software performs reliably in prototype, simulation, and flight environments. The selected candidates will play a key role in supporting commercial human spaceflight modules through rigorous test execution and analysis.
Key Duties:
  • Plan, develop, execute, and document software verification and validation test procedures for flight and ground software systems.
  • Perform hardware/software integration testing across systems such as propulsion, command & data handling (C&DH), environmental control and life support systems (ECLSS), guidance, navigation and control (GN&C), caution and warning (C&W), power, networks, and datalinks.
  • Support software test activities in prototype, simulation, and flight environments, including anomaly identification, troubleshooting, and resolution support.
  • Collaborate closely with software developers, systems engineers, and subject matter experts throughout the software test lifecycle.
  • Support configuration control and disciplined test documentation, reporting, and traceability.

Required/Desired Skills, Experience, and Education
Required Skills, Experience, and Education:
  • Due to facility security requirements, only U.S. citizens or permanent residents are eligible for consideration at this time.
  • Ability to complete a pre-employment background check and drug screening, which will include but is not limited to testing for marijuana use.
  • 5 or more years of related experience in software test, verification, or integration roles.
  • Experience working with software written in languages such as C, C++, Rust, VHDL, and Python in a Linux environment.
  • Good written, verbal, and interpersonal communication skills.
  • Bachelor of Science in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, Computer Engineering, Computer Science, Computer Information Systems, or another related technical discipline.

Desired Skills, Experience, and Education:
  • Flight software experience.
  • Experience with Scrum and the Agile framework using tools such as JIRA
  • Experience with Git, Model Based Systems Engineering (MBSE), JAMA, and Confluence.
  • Comfortable with common embedded communication protocols such as UART, SPI, I2C, USB, RS-232/422/485, and Ethernet.
  • Experience working with networking protocols such as TSN, UDP, and TCP.
