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":"17 of these GTSAM jobs state pay directly. Across them the middle half of the market sits between $161K and $300K a year, with a median of $240K. 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 China (6), Germany (3), France (2), South Korea (2), and United States (1). 9% of the listings are fully remote and a further 9% are hybrid, so a large part of this market is open to you regardless of where you live."},{"title":"Who is hiring","text":"The employers with the most open GTSAM jobs right now are PaXini (4), FieldAI (3), SinoGNSS (2), Mecka (2), Applied Intuition (2), and AeroVect (2). 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 GTSAM (44), C++ (37), Python (28), SLAM (22), ROS (18), Sensor Fusion (18), Linux (13), and ROS2 (12). 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 GTSAM jobs, 2 offer a relocation package and 8 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 GTSAM jobs are open right now?","answer":"There are 44 open GTSAM jobs on Alion from 34 companies. The list was last refreshed on October 16, 2026."},{"question":"Are all of these GTSAM jobs still being filled?","answer":"Probably not all of them. 4 of the 44 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 GTSAM jobs pay?","answer":"The median is $240K a year, and the middle half of the market falls between $161K and $300K. This is based on the 17 listings that state pay."},{"question":"Are any of these roles remote?","answer":"4 of the 44 listings (9%) 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 PaXini, FieldAI, SinoGNSS, Mecka, Applied Intuition, and AeroVect. 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, 2 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":2598169,"url":"https://alion.io/job/ibee-3dshijuesuanfagongchengshislam-iweizhongjianfangxiang","json_url":"https://alion.io/job/ibee-3dshijuesuanfagongchengshislam-iweizhongjianfangxiang.json","title":"3D视觉算法工程师（SLAM
