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.
