What this job asks for AI summary
This is a systems engineering role supporting NASA's Space Launch System (SLS) Core Stage, focused on liquid rocket engine systems — specifically the RS-25 engine. Day-to-day work involves hot-fire test support, pre- and post-test data analysis, anomaly investigations, performance modeling, and preparing technical documentation and presentations for design reviews. It suits an early-career aerospace engineer with some propulsion or test-and-data background.

How this req sits in the market our data
What the occupation pays Median $123,099 (middle half $94,422–$145,807).
Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 29, 2026. It is a model, not a headcount.
Why we read it this way (6)
This role is primarily aerospace/propulsion systems engineering, not a computer or mathematical occupation. It was mapped to 15-1299 (Computer Occupations, All Other) as the closest available code, but the role is fundamentally an aerospace/mechanical systems engineer role — a non-technology classification would arguably be more accurate given the day-to-day work. The computer-programming requirement is a supporting tool skill, not the primary occupation.
The posting prefers 1–5 years of experience and frames the role as entry-to-early-career; seniority is assessed as Junior accordingly.
No specific compensation figures are provided — the posting references an internal grade code ('ES2') and states only that a range exists as a good-faith estimate, without disclosing actual numbers.
US Citizenship and a STAR ID are hard requirements stated in the posting. No formal security clearance is gated, but citizenship is mandatory.
The specific programming languages (Python, FORTRAN, VBA, MATLAB, C++) are listed as 'desirable' in the qualifications. The posting does hard-require 'experience using computer programming to efficiently solve engineering problems' without naming a specific language, so the named languages are captured as preferred. They are listed as alternatives to each other since the posting treats them as a group of options.
Location is not explicitly stated in the posting, but the role involves work at NASA facilities and is consistent with NASA's Marshall Space Flight Center in Huntsville, AL, where SLS Core Stage work is centered. This is an inference — the posting does not name a city.
