Every listing links straight to the employer, so you apply on their own board rather than through an intermediary."},{"title":"What these roles pay","text":"94 of these Backend Developer jobs in El Segundo state pay directly. Across them the middle half of the market sits between $170K and $237K a year, with a median of $190K. By level, the median runs junior at $140K, middle at $144K, senior at $216K, staff at $187K, and lead at $225K. The step from junior to lead is worth about 1.6x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable."},{"title":"Where the work is","text":"The largest concentrations of these roles are United States (10). 12% offer a hybrid arrangement, while the rest expect you on site."},{"title":"Who is hiring","text":"The employers with the most open Backend Developer jobs in El Segundo right now are Boeing (19), RTX (15), CHAOS Industries (10), Freeform (9), Northrop Grumman (7), and The Aerospace Corporation (6). Each company page on Alion carries its size, funding stage, tech stack and every other position it has open, so you can judge the employer before you spend an evening on the application."},{"title":"What employers ask for","text":"Reading across the current listings, the tools that come up most often are Python (64), C++ (53), CI/CD (48), Agile (46), JavaScript (38), Linux (37), Java (35), and Docker (28). The counts are how many of these openings name each one, which is a better guide to what is actually being hired for than a generic skills list."},{"title":"Relocation, visas and equity","text":"Of the current Backend Developer jobs in El Segundo, 69 offer a relocation package and 30 include equity. These are filters on the list above, so you can narrow it to the ones that make a move possible for you."}],"faq":[{"question":"How many Backend Developer jobs in El Segundo are open right now?","answer":"There are 103 open Backend Developer jobs in El Segundo on Alion from 28 companies. The list was last refreshed on October 24, 2026."},{"question":"Are all of these Backend Developer jobs in El Segundo still being filled?","answer":"Probably not all of them. 2 of the 103 show the marks Alion reads as a likely inactive posting: open far longer than employers usually take to fill such a role, reposted several times, or sitting on a board that rarely closes anything. They stay listed with a warning, and the list can hide them with one switch."},{"question":"What do Backend Developer jobs in El Segundo pay?","answer":"The median is $190K a year, and the middle half of the market falls between $170K and $237K. This is based on the 94 listings that state pay."},{"question":"Are any of these roles remote?","answer":"4 of the 103 listings (4%) are fully remote, and you can filter the list down to them in one click."},{"question":"Which companies are hiring?","answer":"The most active employers right now are Boeing, RTX, CHAOS Industries, Freeform, Northrop Grumman, and The Aerospace Corporation. Each has its own page on Alion with the rest of its open roles."},{"question":"Can I get visa sponsorship or relocation?","answer":"Yes - of the current listings, 69 offer a relocation package. Both are filters on the jobs page."},{"question":"How do I apply?","answer":"Open any listing and apply on the employer's own board through the link on the page. No account is required to browse or to apply."}]},"jobs":[{"id":3194520,"url":"https://alion.io/job/varda-space-industries-senior-mission-software-engineer-4","json_url":"https://alion.io/job/varda-space-industries-senior-mission-software-engineer-4.json","title":"Senior
