ECLSS Hardware Development Engineer

Leidos • Webster, TX

5d • $87,100 - $157,450 • Onsite

About The Position

Leidos is seeking an experienced Environmental Control and Life Support Systems (ECLSS) Hardware Development Engineer to advance life support technologies for NASA and commercial human spaceflight missions. The team is developing a next-generation spacecraft waste management system for NASA and pursuing opportunities to deliver ECLSS technologies and hardware for commercial space stations.

The engineer applies spacecraft systems expertise to complex engineering challenges and supports the design, development, integration, testing, and certification of human spaceflight hardware. The role involves collaboration with NASA technical experts, commercial spaceflight partners, and multidisciplinary engineering teams. The position is based onsite in Webster, Texas, near NASA Johnson Space Center. A temporary remote-work arrangement may be considered to support relocation, with periodic travel to Webster as needed; the selected candidate must transition to onsite work within six months of hire. Travel may also be required as needed.

Requirements

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline with at least 8 years of relevant experience, or a master's degree with at least 6 years of relevant experience.
• Demonstrated experience with spacecraft ECLSS, including hardware development, integration, testing, operations, or troubleshooting.
• Experience evaluating engineering requirements, system performance, and operational constraints to develop technical solutions.
• Demonstrated ability to troubleshoot complex engineering challenges and collaborate across multidisciplinary technical teams.
• Strong analytical, problem-solving, technical documentation, and communication skills.
• Ability to obtain and maintain the required Public Trust designation.
• Must be a U.S. citizen or U.S. permanent resident due to contract requirements.
• Ability to work onsite in Webster, Texas, after any approved temporary remote-work transition, and travel as required.

Nice To Haves

• Direct experience with International Space Station ECLSS or other NASA human spaceflight programs.
• Technical expertise in spacecraft waste management, water recovery, regenerative life support, atmospheric revitalization, or related ECLSS technologies.
• Experience developing, testing, verifying, or certifying human-rated spaceflight hardware.
• Knowledge of NASA engineering standards, safety requirements, and hardware certification processes.
• Experience with spacecraft anomaly resolution, failure investigations, or operational risk mitigation.
• Experience developing engineering requirements, operational concepts, trade studies, or test procedures.
• Experience supporting technical proposals, customer requirements assessments, or new business development.
• Master's degree in a relevant engineering discipline.

Responsibilities

• Support the design, development, integration, testing, verification, and certification of ECLSS hardware for NASA and commercial human spaceflight programs.
• Evaluate technical requirements, operational needs, system interfaces, and performance constraints to develop practical engineering solutions.
• Apply spacecraft ECLSS expertise to hardware design decisions, engineering trade studies, technical risk assessments, and system performance evaluations.
• Collaborate with multidisciplinary engineering teams, NASA technical experts, and commercial partners to resolve engineering challenges and support project execution.
• Support hardware testing, troubleshooting, anomaly investigations, and verification and validation activities.
• Develop and review engineering documentation, including technical requirements, specifications, test procedures, and verification products.
• Participate in technical and design reviews, identifying opportunities to improve system performance, mitigate risks, and leverage common technologies across projects.
• Provide technical expertise for emerging ECLSS opportunities, including customer requirements assessments, RFIs, RFPs, cost estimates, and proposal development.
