Fastest-Growing Tech Companies Hiring — July 2026

Which tech companies are hiring fastest right now?

Neura Robotics leads every company we track this month with +364 net new openings over the last 28 days — more than double the next name on the list. That's from 380 roles opened against almost none closed, leaving 364 active postings. When a company's opened count and net figure are that close, it means the board is filling up and staying full: they aren't churning listings, they're expanding.

Behind Neura sits SpaceX at +183, though the shape is different. SpaceX opened 519 roles and carries 1,726 active — the largest live footprint in our data by a wide margin — so its net gain rides on top of an already-huge board. Neura's growth is the story of a board that barely existed at this scale a month ago; SpaceX's is steady scaling on an enormous base.

Rounding out the top five: Cssmerge at +169, Fluidstack at +168, and Mistral AI at +145. A quick reminder on what these numbers are: net new openings in the direct-apply job boards we monitor (Greenhouse, Lever, Ashby), not company-wide headcount, revenue, or anything I can't measure from a posting. Staffing and consultancy shops are excluded so the ranking reflects companies hiring for themselves.

Where is tech hiring growing this month?

Two places, mostly: physical AI and the compute that feeds it. The niche breakdown makes it plain — AI/ML roles added +479 net, far ahead of everything else, and DevOps & Infra came second at +227. Those two categories account for the bulk of the market's modest overall net of +545.

The robotics cluster is the sharpest signal. Neura at the top, 1X at +80, and Allen Control Systems at +76 are all building teams to put AI into moving hardware. If you'd told me a year ago that a humanoid-and-industrial-robotics group would out-hire nearly every pure software name in a single month, I'd have wanted to see the data first. Here it is.

The compute story runs right alongside it. Fluidstack (+168), Cerebras (+120), and Nscale (+62) are all in the AI-infrastructure lane, and Mistral AI (+145) is the model-builder in the top five. GPU capacity, silicon, and the ops teams to run them — that's where Fluidstack's and Nscale's DevOps demand is coming from. Nscale is worth a footnote: it opened 156 roles but nets +62, so it's closing and reopening more than the leaders. Legora shows the same pattern (82 opened, +52 net, 197 active) — active boards with real turnover, not just accumulation.

Which energy and infrastructure companies are hiring?

A quieter but consistent group sits in energy and heavy build. Holder Construction posted +107, Terrapower +80, Form Energy +73, Onenergy +62, and Bakerhicks +76. None of these are AI plays, but they land high on the board because they're opening steadily and closing little. Form Energy is the standout here — 172 active roles on +73 net, meaning it's carrying more open positions than its month's growth suggests. If your background is grid, storage, or construction engineering rather than transformers-the-model, this is the cluster to watch.

What about security, product, and design?

Nord Security is the clearest security-sector mover at +103, and it pulls the whole security niche to +107 net — meaning Nord is doing most of the heavy lifting in that category by itself. Product roles grew +157 and design +102, both healthy. Doctolib (+100), Superhuman Platform (+73), and Headway (+62) are the recognisable software-product names carrying that demand. Temporal (+58) and Voleon (+53) fill out the infrastructure-and-quant end of the list.

Where is tech hiring shrinking?

Mobile, and it isn't close. Mobile roles fell -419 net across everything we track — the single largest move in either direction, bigger than AI/ML's gain. Full-stack (-57), frontend (-32), and data (-28) also ended the window underwater. Backend barely held positive at +9.

So the market's overall +545 hides a real split: AI, infra, product, security, and design pulling up; mobile and generalist web engineering pulling down hard. If your last three roles were mobile-first, the direct-apply data is telling you to widen your search or reposition toward the infra and ML side where the openings actually are.

What should a job-seeker do with this?

Concretely: if you build robotics, AI infrastructure, or ML systems, the volume is genuinely there this month, and Neura Robotics, Fluidstack, Cerebras, Mistral AI, and 1X are the boards worth checking first — several of them show net figures nearly equal to their opened counts, which means the roles are still live rather than already filled and churning. For those outside AI, the energy cluster (Form Energy, Terrapower, Holder) and Nord Security in the security lane are the most reliable non-AI bets on this list.

One honest caveat: a high net-new number tells you a company is scaling its team right now, not that it's a stable or safe employer, and not how many total people work there. It's a velocity signal — best used to decide where the doors are open this week, then paired with your own homework. Mobile engineers especially should treat the -419 as a nudge to look at adjacent backend and infra roles, where the hiring is. I'll re-run these numbers next month; the robotics-and-compute concentration is the trend I'll be watching to see whether it holds or was a July spike.
