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 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 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 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.

Job description

ECLSS System Engineer
Onsite Kennedy Space Center /  Florida - No hybrid or remote is available.
NASA or AEROSPACE Exp
US Citizens or Perm Residents Only
These are immediate interviews for the right candidates.
We are looking for a ECLSS System Engineer to join our team to support Spacecraft systems
As a ECLSS System Engineer you will:
  • Review system architectures, hardware requirements, designs, assembly procedures, test plans, procedures, and data in support of the Deep Space Logistic Modules Environmental Control and Life Support System (ECLSS) to ensure approaches are sound, component/material selection is appropriate for the intended usage, and suitable for the proposed application. 
  • Provide recommendations for improvements to system architectures, hardware requirements, designs, test plans, and procedures if disparities/deficiencies are identified.
  • Ensure requirements are satisfied by design solutions and support production/control board meetings, design, and system reviews.
  • Track ECLSS verification and safety action items and schedules 
  • Provide engineering insight in support for DSL Logistic Modules providers for their Environmental Control and Life Support System (ECLSS). Review plans and schedules for the manufacturing, fabrication, procurement, assembly, testing and certification of the LM ECLSS
  • Evaluate various options, utilizing matrix organization support as necessary, to offer best technical guidance about various trade-offs (technical, schedule, risk, etc.)
  • Work in a team environment
  • Coordinate with the team on programmatic requirement change requests, design review support, interface definition and control, verification integration, and provide status on high level development progress and issues.
  • Travel as required in support of technical reviews and exchanges. 
  • Work both independently and in a team environment, and report directly and support System Management
  • Select and apply engineering techniques and procedures to analyze and evaluate specific problems, data, or other features of the work which are broad in scope and complexity
  • Provide recommendations for program acceptance of requirements verification, testing, risks and hazards. 
  • Perform other duties as required 
Here’s What You’ll Need:
This position will be targeted as a Junior level engineer 2-5 years experience
  • BS degree in engineering from an accredited engineering school.
  • Experience with one or more of the following:
    • Experience with leak rates, mass flow, chemical analysis and analytics or MATLAB
    • Hands on experience with one or more of the following: fluid systems, pressure vessel/COPVs, valves/solenoids, regulators, fans, commonly used sensors for life support systems (pressure, temperature, CO2/O2, etc.) and their performance signatures, failures/troubleshooting, and monitoring
    • Experience in the design, assembly, testing, certification, and operation of flight hardware 
  • Basic knowledge of commonly used concepts, practices, and procedures in the field, such as mechanical system design, engineering drawings and sketches, material selection, testing, and office software 
  • Highly organized and self-motivated
  • Excellent oral and written communication skills and the ability to coordinate support from a wide range of technical disciplines 
Requisition Preferences:
  • Experience with the Environmental Control and Life Support Systems (ECLSS) which may include but not be limited to carbon dioxide removal systems, oxygen generation systems, and air monitoring systems, waste management systems.
