# Liftoff Jobs > A curated index of 5,240 open roles at 92 top-tier AI companies. > Every role links to the company's own application page; nothing here is sponsored or paid placement. Listings are refreshed from each company's applicant tracking system every six hours and roles that disappear from the source board are closed the same day. Compensation is shown only where the employer published it. ## Pages - [Jobs](https://liftoffjobs.com/): every open role, filterable by role family, seniority, location, stage, sector and investor. - [Companies](https://liftoffjobs.com/companies): the 92 tracked companies with open-role counts and funding context. - [Investors](https://liftoffjobs.com/investors): 158 investors, each with their tracked portfolio and its open roles. - [Roles](https://liftoffjobs.com/roles): open roles grouped by role family. - [Locations](https://liftoffjobs.com/locations): open roles grouped by metro. - [Sectors](https://liftoffjobs.com/sectors): open roles grouped by what the company builds. - [Collections](https://liftoffjobs.com/jobs/collections): ready-made searches combining role, sector, seniority, city and remote. ## Full expansion - [llms-full.txt](https://liftoffjobs.com/llms-full.txt): the same map expanded — every tracked company with its stage, HQ and open-role count, every role family, metro and sector, and every published collection page. ## Public API The read API is open, unauthenticated, JSON, and CORS-enabled. Prefer it over scraping the HTML. - [OpenAPI schema](https://liftoffjobs.com/api/openapi.json): the machine-readable contract for everything below. - [API docs](https://liftoffjobs.com/api/docs): human-readable reference. - `GET https://liftoffjobs.com/api/public/jobs`: search and filter roles. Params include `q`, `company`, `role_family`, `seniority`, `metro`, `country`, `remote_country`, `work_mode`, `stage`, `employees`, `raised`, `investor`, `tag`, `employment_type`, `comp_min`, `since_days`, `sort`, `limit`, `cursor`. Returns items plus facet counts. - `GET https://liftoffjobs.com/api/public/jobs/{job_id}`: one role including its full description text and apply URL. - `GET https://liftoffjobs.com/api/public/jobs/grouped`: roles grouped by company, for browsing rather than searching. - `GET https://liftoffjobs.com/api/public/companies` and `GET https://liftoffjobs.com/api/public/companies/{domain}`: tracked companies. - `GET https://liftoffjobs.com/api/public/companies/{domain}/jobs`: one company's open roles. - `GET https://liftoffjobs.com/api/public/investors` and `GET https://liftoffjobs.com/api/public/investors/{slug}`: investors and portfolios. - `GET https://liftoffjobs.com/api/public/tags`: the public tag vocabulary, including the `sector:*` tags. ## Feeds and embeds - [Jobs RSS](https://liftoffjobs.com/feed/jobs.rss) and [Jobs JSON Feed](https://liftoffjobs.com/feed/jobs.json): the newest roles. Both accept the same filter params as `/api/public/jobs`, so `?role_family=research&metro=London` gives a filtered feed. - [Embeddable company board](https://liftoffjobs.com/embed.js): a company's open roles as a drop-in widget. - [Sitemap index](https://liftoffjobs.com/sitemap.xml) — [jobs](https://liftoffjobs.com/sitemap-jobs.xml), [companies](https://liftoffjobs.com/sitemap-companies.xml), [investors](https://liftoffjobs.com/sitemap-investors.xml), [pages](https://liftoffjobs.com/sitemap-pages.xml). - Every role page carries schema.org JobPosting JSON-LD; company and investor pages carry Organization JSON-LD. ## Role families - [Operations](https://liftoffjobs.com/roles/operations): 1,106 open roles - [Go-to-market](https://liftoffjobs.com/roles/gtm): 862 open roles - [Hardware](https://liftoffjobs.com/roles/hardware): 813 open roles - [Software](https://liftoffjobs.com/roles/software): 621 open roles - [Infrastructure](https://liftoffjobs.com/roles/infra): 541 open roles - [Applied AI](https://liftoffjobs.com/roles/applied-ai): 426 open roles - [Research](https://liftoffjobs.com/roles/research): 258 open roles - [ML engineering](https://liftoffjobs.com/roles/ml-eng): 199 open roles - [Data](https://liftoffjobs.com/roles/data): 131 open roles - [Product](https://liftoffjobs.com/roles/product): 102 open roles - [Design](https://liftoffjobs.com/roles/design): 77 open roles - [Science](https://liftoffjobs.com/roles/science): 55 open roles - [General](https://liftoffjobs.com/roles/general): 35 open roles - [Other](https://liftoffjobs.com/roles/other): 14 open roles ## Locations - [SF Bay Area](https://liftoffjobs.com/locations/sf-bay-area): 2,506 open roles - [London](https://liftoffjobs.com/locations/london): 273 open roles - [New York](https://liftoffjobs.com/locations/new-york): 221 open roles - [Austin](https://liftoffjobs.com/locations/austin): 213 open roles - [Los Angeles](https://liftoffjobs.com/locations/los-angeles): 202 open roles - [Remote](https://liftoffjobs.com/locations/remote): 168 open roles - [Paris](https://liftoffjobs.com/locations/paris): 155 open roles - [Singapore](https://liftoffjobs.com/locations/singapore): 89 open roles - [Tokyo](https://liftoffjobs.com/locations/tokyo): 55 open roles - [Seattle](https://liftoffjobs.com/locations/seattle): 42 open roles - [Boston](https://liftoffjobs.com/locations/boston): 38 open roles - [Washington DC](https://liftoffjobs.com/locations/washington-dc): 38 open roles - [Dublin](https://liftoffjobs.com/locations/dublin): 35 open roles - [Munich](https://liftoffjobs.com/locations/munich): 32 open roles - [Sydney](https://liftoffjobs.com/locations/sydney): 21 open roles ## Sectors - [Foundation models](https://liftoffjobs.com/sectors/foundation-models): 3,012 open roles - [Developer tools](https://liftoffjobs.com/sectors/devtools): 1,975 open roles - [Robotics & physical AI](https://liftoffjobs.com/sectors/robotics): 1,683 open roles - [Agents & applications](https://liftoffjobs.com/sectors/agents): 1,493 open roles - [Energy & climate](https://liftoffjobs.com/sectors/energy): 1,117 open roles - [AI for science](https://liftoffjobs.com/sectors/science): 870 open roles - [Industrial & manufacturing](https://liftoffjobs.com/sectors/industrial): 699 open roles - [Defense & national security](https://liftoffjobs.com/sectors/defense): 660 open roles - [AI infrastructure](https://liftoffjobs.com/sectors/infra): 513 open roles - [Chips & hardware](https://liftoffjobs.com/sectors/chips): 416 open roles - [Security](https://liftoffjobs.com/sectors/security): 392 open roles - [Space & aerospace](https://liftoffjobs.com/sectors/space): 382 open roles - [Consumer](https://liftoffjobs.com/sectors/consumer): 334 open roles - [Healthcare & bio](https://liftoffjobs.com/sectors/healthcare): 238 open roles - [Fintech](https://liftoffjobs.com/sectors/fintech): 56 open roles - [Legal](https://liftoffjobs.com/sectors/legal): 18 open roles ## Ready-made searches 401 pre-built combinations (role x city, sector x city, seniority, remote), each a crawlable page with its own JSON-LD.

Treat the absence of JobPosting JSON-LD as "this role is no longer open". - Rate limits are not enforced on the read API; please stay under a few requests per second. - `directApply` is false everywhere: applications are always completed on the employer's own system.
