AI Hiring Brief · 2026-09-07

32 frontier AI labs · 2 roles added in 24h · agihunt.info/en/jobs

Today at a glance

ByteDance's purge: ByteDance Doubao/Seed (字节跳动豆包/Seed) closed 79 listings today with zero new postings — the single largest movement of any lab this cycle, and enough to wipe out nearly all of its 9 net additions over the past 7 days.
OpenAI eyes physical footprint: OpenAI's lone new posting today, "Site Selection Lead" under its Scaling function (San Francisco; Seattle), points to continued work on where to physically build out compute and infrastructure capacity.
Together AI's agent-infra hire in Europe: Together AI added a "Senior Software Engineer — Infra Agent Systems" role in Amsterdam — a small but specific signal of agent-infrastructure investment reaching its European operations.
A quiet day almost everywhere else: of the 32 labs tracked, only OpenAI and Together AI added anything in the last 24 hours; the rest — including high-volume adders like Microsoft AI and StepFun — saw no change today.
Selective trims at the majors: Anthropic, Microsoft AI, NVIDIA, and Baidu AI all closed a handful of listings today (2, 10, 2, and 3 respectively) without adding replacements — ordinary pipeline turnover rather than a retreat, given their strong 7-day totals.

Company moves

OpenAI (780 open; 68 added over 7 days) added one role today, the "Site Selection Lead" in Scaling — consistent with the physical build-out work OpenAI has been staffing for.

Anthropic (592 open; 68 added over 7 days) closed 2 listings today with no new postings, a minor trim against a week of steady accumulation.

Microsoft AI (595 open; 220 added over 7 days) closed 10 listings today and added none — by far the fastest weekly adder of any tracked lab, so today's closures read as normal churn inside a much larger hiring wave.

NVIDIA (561 open; 33 added over 7 days) closed 2 listings today, a quiet day after a week of consistent growth.

Together AI (59 open; 3 added over 7 days) added the "Senior Software Engineer — Infra Agent Systems" role in Amsterdam, its Engineering department — a specific, small-scale signal of agent-infrastructure hiring reaching Europe.

Baidu AI (百度 AI) (449 open; 10 added over 7 days) closed 3 listings today with no new roles, a modest trim against ongoing weekly growth.

ByteDance Doubao/Seed (字节跳动豆包/Seed) (873 open; 9 added over 7 days) closed 79 listings today and added nothing — the largest closure count in this dataset by a wide margin, effectively erasing its already-thin weekly net growth.

The remaining 25 tracked labs — Google DeepMind, Meta AI, Apple AIML, SpaceXAI, Perplexity, Mistral AI, Cursor, Lovable, Cohere, Scale AI, Cerebras, Pika Labs, Aleph Alpha, Genmo, Moonshot AI (Kimi) (月之暗面 Kimi), DeepSeek (深度求索), Zhipu AI (智谱 AI), StepFun (阶跃星辰), ModelBest (面壁智能), Meituan LongCat (美团·龙猫), Tencent Hunyuan (腾讯混元), MiniMax (Hailuo) (MiniMax 海螺), 01.AI (Yi) (零一万物), SenseTime SenseNova (商汤日日新), and Alibaba Tongyi Qwen (阿里通义千问) — showed no change in the last 24 hours.

What it signals

The 7-day figures show a widening gap in hiring pace between the largest US labs and everyone else. Microsoft AI's 220 additions over the week dwarfs the next-highest tallies — OpenAI and Anthropic tied at 68 apiece — and even Microsoft's mid-sized peers (Google DeepMind at 11, Meta AI at 22, Apple AIML at 22, SpaceXAI at 23) are growing at a fraction of that rate. That concentration suggests the heaviest hiring load right now sits with a small handful of labs rather than being spread evenly across the frontier.

Among Chinese labs, the picture is more fragmented. StepFun's 43 additions over 7 days stand out as the clear outlier — a continuation of the commercial hiring sprint visible in recent days — while six of the thirteen China-based labs tracked (DeepSeek, Zhipu AI, Meituan LongCat, 01.AI, SenseTime SenseNova, and Alibaba Tongyi Qwen) show zero net change over the same week. That split points to uneven momentum: a couple of labs actively building out teams while a larger group holds headcount flat, at least in visible postings.

ByteDance Doubao/Seed is the clearest case of churn without growth in this dataset. It carries the single largest open-role count of any tracked company at 873, yet its 7-day net addition is only 9, and a single day of 79 closures with no replacements nearly erased that. Large standing job boards paired with heavy, uneven closure activity look more like routine listing turnover or pipeline cleanup than a hiring slowdown — but it's worth watching whether ByteDance's open count contracts meaningfully in the next few cycles or simply refills.

Elsewhere, the day's only two new postings are narrow but specific: OpenAI's site-selection hire keeps pointing toward physical infrastructure decisions (where to place compute and facilities), while Together AI's Amsterdam-based infra-agent engineer is a small marker of agent-systems investment extending into a European base. Neither is enough to call a trend on its own, but both fit patterns already visible in the 7-day data — infrastructure and agent tooling remain areas of active, if incremental, hiring even on an otherwise quiet day across the rest of the tracked field.
