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":"455 of these Tech jobs in Costa Mesa state pay directly. Across them the middle half of the market sits between $194K and $253K a year, with a median of $220K. By level, the median runs junior at $186K, middle at $220K, senior at $220K, staff at $253K, lead at $253K, and head+ at $295K. The step from junior to head+ 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 (6). Most of these positions are on-site roles tied to a specific office."},{"title":"Who is hiring","text":"The employers with the most open Tech jobs in Costa Mesa right now are Anduril Industries (556), SpaceNexus (4), Fresh Consulting (2), Fisher & Paykel (2), Siemens (1), and Elevance Health (1). 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 Computer Vision (560), Sensor Fusion (560), Python (226), C++ (196), Rust (147), Linux (136), MATLAB (87), and CI/CD (75). 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 Tech jobs in Costa Mesa, 43 offer a relocation package and 561 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 Tech jobs in Costa Mesa are open right now?","answer":"There are 573 open Tech jobs in Costa Mesa on Alion from 13 companies. The list was last refreshed on October 16, 2026."},{"question":"Are all of these Tech jobs in Costa Mesa still being filled?","answer":"Probably not all of them. 1 of the 573 shows 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 Tech jobs in Costa Mesa pay?","answer":"The median is $220K a year, and the middle half of the market falls between $194K and $253K. This is based on the 455 listings that state pay."},{"question":"Are any of these roles remote?","answer":"2 of the 573 listings (0%) 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 Anduril Industries, SpaceNexus, Fresh Consulting, Fisher & Paykel, Siemens, and Elevance Health. 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, 43 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":2747594,"url":"https://alion.io/job/anduril-industries-finance-master-data-management","json_url":"https://alion.io/job/anduril-industries-finance-master-data-management.json","title":"Finance, Master Data Management","company":{"id":14,"name":"Anduril Industries","url":"https://alion.io/company/anduril"},"work_mode":"on_site","salary":{"min":112000,"max":149000,"currency":"USD","period":"year"},"status":"live","updated_at":"2026-10-16T22:44:43+00:00"},{"id":2747596,"url":"https://alion.io/job/anduril-industries-product-manager-erp","json_url":"https://alion.io/job/anduril-industries-product-manager-erp.json","title":"Product Manager, ERP","company":{"id":14,"name":"Anduril Industries","url":"https://alion.io/company/anduril"},"work_mode":"on_site","salary":{"min":146000,"max":194000,"currency":"USD","period":"year"},"status":"live","updated_at":"2026-10-16T22:18:20+00:00"},{"id":2747597,"url":"https://alion.io/job/anduril-industries-classified-platform-engineer","json_url":"https://alion.io/job/anduril-industries-classified-platform-engineer.json","title":"Classified Platform Engineer","company":{"id":14,"name":"Anduril Industries","url":"https://alion.io/company/anduril"},"work_mode":"on_site","salary":{"min":166000,"max":220000,"currency":"USD","period":"year"},"status":"live","updated_at":"2026-10-16T22:10:09+00:00"},{"id":2747225,"url":"https://alion.io/job/siemens-software-engineer-5","json_url":"https://alion.io/job/siemens-software-engineer-5.json","title":"Software Engineer","company":{"id":131,"name":"Siemens","url":"https://alion.io/company/siemens"},"work_mode":"hybrid","salary":null,"status":"live","updated_at":"2026-10-16T22:43:48+00:00"},{"id":2646588,"url":"https://alion.io/job/fresh-consulting-senior-test-automation-engineer-fresh-consulting","json_url":"https://alion.io/job/fresh-consulting-senior-test-automation-engineer-fresh-consulting.json","title":"Senior Test Automation Engineer -
