This note captures the state of AI engineering hiring on 2026-06-01, pulled directly from the AI Dev Jobs public API. The numbers are not a survey. They are a live, daily-refreshed index of what companies are actually posting to their own applicant tracking systems right now — scraped continuously from the AI Dev Jobs ATS source feed network, deduplicated, and canonicalized.
Top 10 hiring companies right now
The concentration at the top is striking. OpenAI, Anthropic, and Anduril alone account for 809 open roles — roughly 9% of the entire index. The top 10 companies account for 1,745 roles, or 19.7% of the market. This is a market with a long tail (510 companies below the top 10) but also with serious pockets of single-company acceleration.
| Company | Open roles | Avg salary |
|---|---|---|
| OpenAI | 382 | $302,409 |
| Anthropic | 238 | $384,930 |
| Anduril | 189 | $202,141 |
| Graphcore | 173 | $220,919 |
| Applied Intuition | 172 | $195,103 |
| Nebius | 157 | $187,187 |
| Scale AI | 124 | $243,421 |
| Waymo | 105 | $251,704 |
| Harvey AI | 104 | $240,235 |
| LILT | 101 | — |
The frontier labs (OpenAI, Anthropic, xAI) pay a premium of roughly $123k over the defense-tech, autonomy, and infrastructure players in the same leaderboard. That gap is the clearest signal in the data about where investor capital is being deployed most aggressively right now.
Top demanded skills
LLM work now dominates the index. 2,636 of 8,869 roles (29.7%) list llm as a tag. agents is close behind at 2,589 (29.2%), and generative-ai sits at 1,815 (20.5%). A year ago pytorch and deep-learning led by volume. The demand center of gravity has migrated up the stack — from model training to model orchestration and agent design.
| Tag | Role count | Avg salary |
|---|---|---|
| llm | 2,636 | $245,362 |
| agents | 2,589 | $230,812 |
| generative-ai | 1,815 | $239,453 |
| distributed-systems | 1,498 | $257,128 |
| pytorch | 1,030 | $249,372 |
| fine-tuning | 827 | $250,610 |
| research | 760 | $275,961 |
| reinforcement-learning | 591 | $270,450 |
| mlops | 614 | $226,325 |
| gpu | 533 | $236,595 |
Research roles command the highest average salary ($275,961) among tags with 500+ roles, followed by reinforcement learning and search. The premium for specialized, harder-to-hire skills is intact — training infrastructure and eval/reliability work (distributed systems, MLOps, GPU) continues to outpay generic application work.
Salary distribution
Of the 3,556 roles that publish salary ranges, the shape is bimodal around the $200k line. The $200-250k band is the single largest bucket (1,065 roles, 29.9%), with $150-200k close behind (997 roles, 28.0%). Everything below $150k is a minority (373 roles combined, 10.5%), and roles above $300k are a meaningful but not overwhelming slice (541 roles, 15.2%).
| Range | Roles | Share |
|---|---|---|
| Under $100k | 72 | 2.0% |
| $100k-$150k | 301 | 8.5% |
| $150k-$200k | 997 | 28.0% |
| $200k-$250k | 1,065 | 29.9% |
| $250k-$300k | 580 | 16.3% |
| $300k-$400k | 406 | 11.4% |
| $400k+ | 135 | 3.8% |
Workplace mix
Onsite is still the largest category by volume (4,903 roles, 55.3%), but hybrid roles pay the highest on average: $261,948 versus $219,027 for onsite and $222,910 for remote. The $39k hybrid premium is real and worth pausing on — it suggests the companies paying the most for senior talent right now want people in the building at least part of the week. Remote pay tracks onsite almost exactly.
| Workplace | Roles | Share | Avg salary |
|---|---|---|---|
| Onsite | 4,903 | 55.3% | $219,027 |
| Remote | 2,394 | 27.0% | $222,910 |
| Hybrid | 1,572 | 17.7% | $261,948 |
The ecosystem side
Hiring demand is not the only signal. On the infrastructure side, NothingHumanSearch — an independent index of agent-ready web services — now tracks 4,191 sites with agent discovery files (llms.txt, OpenAPI, ai-plugin), of which 456 have a live-verified MCP server over JSON-RPC, and 2,270 publish an llms.txt. Developer tools (1,244 sites) and AI-native tools (911 sites) are the two largest categories. Read alongside the hiring data, these two indexes describe the same market from opposite ends: 8,869 humans being hired to build AI products, into a world where 4,191 services are already exposing themselves natively to AI agents.
The story the data tells: the stack is diversifying faster than headcount is. Agent frameworks, eval pipelines, MCP servers, vector infra, and MLOps tooling are all real sub-markets now. Companies that want to hire into this market need to be specific about which layer they are hiring for — generic "ML engineer" listings are competing against a labor pool that self-identifies by framework and problem domain.
Methodology
Data in this note was pulled live at publication. The aidevboard.com index scrapes applicant-tracking feeds (Ashby, Greenhouse, Lever, Workday, custom careers pages) on a daily cron, canonicalizes titles and tags with a rules-based classifier, and dedupes by (company, title, location). The /api/v1/stats endpoint is public and unauthenticated. NHS data is from /digest.json — an index that live-probes sites for agent-discovery signals and MCP endpoints. Both APIs are agent-readable. This page auto-regenerates weekly.
