AI Hiring Brief · 2026-09-05

32 frontier AI labs · 134 roles added in 24h · agihunt.info/en/jobs

Today at a glance

Microsoft's silicon-and-quantum sprint: amid the day's biggest churn (55 added, 80 closed in 24 hours; 231 added over 7 days), Microsoft AI opened a "Principal Subsystem Design Engineer" in Silicon Engineering alongside two quantum roles — "Principal Quantum Materials Engineer" and "Senior Quantum Measurement Engineer," both in West Lafayette, Indiana — while simultaneously pushing sales and solution-architect hires into Switzerland, the Czech Republic, Sweden, Norway, South Africa, Australia, India, and the Philippines.
ByteDance's mass closure, with safety hires surviving: ByteDance Doubao/Seed (字节跳动豆包/Seed) closed 46 listings today — the largest closure count of any company — while its 3 new roles were pointed: "大模型训推安全专家 - 安全与风控" (LLM training/inference security expert – safety & risk control) and a data-platform algorithm engineer, suggesting the pruning is hitting the commercial side rather than safety.
DeepMind's agent-and-world-model cluster: despite a net pullback (7 added vs 9 closed), every new Google DeepMind listing sits in post-training or multimodal territory — "Post-training Agentic Research Scientist," "Research Engineer, World Models," "GDM Staff Software Engineer, Agent Data Quality," and "Senior Research Engineer, Gemini Omni."
Anthropic builds compute plumbing and reaches Seoul: Anthropic added 20 roles, including "Head of Compute Supply Chain," "TPM Manager, Infrastructure," and "Data Infrastructure Engineer, Pre-training," alongside an "Enterprise Account Executive - DNB" based in Seoul — infrastructure scale-up paired with a new enterprise sales foothold in Korea.
Meta leans into robotics and wearables: Meta AI posted a "VP Robotics" and a "Wearables Systems Architect" for Sunnyvale, alongside a "Research Scientist - Multi-modal AI & Efficient Generative Models" — hardware and multimodal research advancing together.

Company moves

OpenAI (774 open; 68 added over 7 days) added 12 roles against 9 closures. Beyond the hardware strategy and infrastructure TPM posts noted above, it added an "Agent Standards Specialist, Global Affairs" in Washington, DC, plus a run of go-to-market hires — a "Client Partner, Ads Solutions - Travel" and account directors for state/local government and tech — pointing to broader enterprise and ads monetization.

Anthropic (593 open; 69 added over 7 days) added 20 roles against 10 closures, the busiest 24 hours of any lab today apart from Microsoft. It also added a "Sanctions Compliance Lead," "Head of Technical Training," "Applied AI, Research Engineer," and "Staff+ Software Engineer, Claude Science" — infrastructure, compliance, and applied research scaling in parallel.

Google DeepMind (65 open) added 7 roles against 9 closures, all inside DeepMind proper and spanning post-training, agent data quality, world models, and a "Product Manager, Cyber Security."

Microsoft AI (602 open; 231 added over 7 days) posted the day's largest churn by far, pairing silicon and quantum engineering hires with an unusually wide international sales and solution-architecture build-out across Europe, Africa, Asia-Pacific, and a Suzhou-based "Principal Software Engineer" in China.

Meta AI (165 open) added 6 roles with zero closures, including the robotics/wearables posts above and a "Data Scientist, Meta Superintelligence Labs (Safety)."

NVIDIA (英伟达, 563 open) added 6 roles against 9 closures, including a "Senior Applied AI Engineer" in Yokneam, Israel, and a "Principal Research Scientist, Synthetic Data Generation" spread across 5 locations.

Apple AIML (苹果 AIML, 290 open) added 3 roles against 6 closures, including a "Full Stack Software Engineer - ML Compute Capacity" in Santa Clara.

SpaceXAI (259 open) added 5 roles with no closures — two of them "AI Tutor" data-labeling roles under Human Data, continuing to build out its human-data pipeline.

Cursor (124 open) added 3 roles, including a "Field Engineer, Public Sector" for Washington, DC, and two paid-media marketing roles — public-sector expansion paired with brand marketing investment.

Scale AI (216 open) added 5 roles against 1 closure, spanning new-grad engineering hires in San Francisco and a "GenAI Compliance Operations & Programs Associate" in Mexico City.

MiniMax (海螺) (196 open) added 5 roles against 5 closures — the busiest day of any Chinese lab — with "大模型工程师-RL框架&算法" (LLM engineer – RL framework & algorithms), a training-framework engineer, a code-focused algorithm engineer, a "K8s 架构师" (K8s architect), and an investor-relations post, all infrastructure- and agentic-coding-adjacent, with the finance hire hinting at fundraising activity.

StepFun (阶跃星辰) (175 open) added 3 roles, including "Agent基建工程师" (Agent infrastructure engineer) and "AI 产品经理-模型评测方向" (AI product manager – model evaluation track).

Smaller moves: Lovable added 1 role — a "Tech Procurement Specialist" in Stockholm — against 1 closure. Cohere and Cerebras each closed roles without adding (1 and 3, respectively), and Meituan LongCat and Baidu AI (百度 AI) each closed a handful without new postings (1 and 3). Perplexity, Mistral AI, Together AI, Pika Labs, Aleph Alpha, Genmo, Moonshot AI (月之暗面 Kimi), DeepSeek (深度求索), Zhipu AI (智谱 AI), ModelBest (面壁智能), Tencent Hunyuan (腾讯混元), 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 net change today.

What it signals

Across the 32 labs tracked today, 134 roles opened against 184 closures — a contraction day, and a lopsided one: Microsoft alone accounts for 80 of the closures and ByteDance for another 46, together covering more than two-thirds of the day's total. That concentration matters more than the headline ratio — most of the field added net-positive or held flat, and the pullback is really a story about two very large employers doing routine high-volume requisition churn rather than a field-wide retrenchment.

Among the global labs, OpenAI (68 added over 7 days) and Anthropic (69) are running at almost identical pace this week, both far ahead of any other individually-tracked lab except Microsoft, whose 231 added over 7 days dwarfs them on volume but comes with proportionally heavier closures — a sign that Microsoft's hiring motion is less a single coherent expansion than parallel, fast-cycling recruiting across many geographies and functions at once, from quantum materials engineering to specialist sellers in Melbourne and Oslo.

The Chinese labs split sharply this week. StepFun (16 added over 7 days) and ModelBest (13) are the most active by a clear margin, both still adding despite zero closures showing in the window — a posture of steady expansion rather than churn. MiniMax (6), Baidu AI (10), Tencent Hunyuan (4), and Moonshot AI (4) trail well behind. Most notably, five model labs that anchor China's frontier conversation — DeepSeek, Zhipu AI, 01.AI, SenseTime SenseNova, and Alibaba Tongyi Qwen — show zero net change over the full 7-day window, a flat line that stands out against the rest of the field and is worth watching for whether it persists.

One theme cuts across geography: agent infrastructure and its evaluation layer are being staffed everywhere at once. DeepMind's "Agent Data Quality" and "Post-training Agentic Research Scientist" posts, StepFun's "Agent基建工程师" and model-evaluation PM, and Anthropic's "Staff+ Site Reliability Engineer, Safeguards ML Infra" all point the same direction — labs are treating agent reliability and evaluation as core infrastructure, not an afterthought. Running alongside it, and distinct from it, is a hardware thread: Meta's VP Robotics and wearables architect, Microsoft's silicon and quantum engineers, and NVIDIA's continued hardware-adjacent hiring suggest that physical-world and chip-level bets are being made concurrently with, not instead of, the software-agent buildout.
