How we picked
We started from public funding news for late September and October 2026, including Magid and Co's weekly tracker, which counted 31 Series A rounds above $8M in the week of October 18 alone. Then we cut three groups: companies without a public job board, rounds we couldn't confirm in the company's own release or a major news outlet, and pure AI research labs (those are in our list of AI companies hiring right now). Seven survived.
Role counts come from each company's own job board on October 26, 2026. A plus sign means the board listed more roles than our snapshot captured. Clera's numbers come from our homepage. Clera is not on this list. We're the data source and the way in.
1. Vinci
Best for: engineers who want physics, high-performance computing and ML in one job.
- On October 6, 2026, Vinci raised a $250M Series B at a $1.5B valuation, led by Advent, Temasek and Xora Innovation (citybiz).
- It builds a foundation model for physics that predicts how chips and hardware behave before they're built, starting with heat. The company says hiring is one of the three uses of the money (Runtime Wire).
- Its careers page lists 37 roles, from thermal simulation and meshing to backend infrastructure, plus solutions engineers in Munich, Paris, Taiwan, Singapore and South Korea.
Why it made the list: the biggest open-role count here, and a stated plan to spend on people.
Downside: nearly every US role sits at the Palo Alto HQ. Remote seekers should skip it.
Stage: Series B, about $296M raised in total.
2. Armadin
Best for: offensive security people and enterprise sellers.
- On October 1, 2026, Armadin raised a $255.5M Series B at more than a $2.5B valuation, led by Andreessen Horowitz and Accel (TechCrunch).
- The founder is Kevin Mandia, who started Mandiant, which Google bought for $5.4B in 2022. Armadin runs always-on attack testing with swarms of AI agents instead of periodic human pen tests.
- Its job board shows regional sales managers in New York, Los Angeles, Florida and Texas, inside sales in Palo Alto and DC, and red team operators.
Why it made the list: two rounds in seven months (a $190M Series A in March) and a sales team being built city by city.
Downside: of the roles we saw, one was listed under engineering. Builders have fewer doors here than sellers.
Stage: Series B, more than $445M raised.
3. Flow Engineering
Best for: software engineers who want to work next to real hardware teams.
- On September 30, 2026, Flow Engineering raised a $50M Series B at a $750M valuation, led by Valor Equity Partners and Atreides Management, with Sequoia returning (TechCrunch).
- Its AI agents keep CAD drawings in line with requirements, simulation and test data. Named customers include Anduril, Rivian, Joby Aviation and Stoke Space.
- The job board lists staff, senior and forward deployed engineers in San Francisco, one engineer in London, and field account executives in Austin, Los Angeles and DC.
Why it made the list: customers you can name at a dinner party, and a mix of engineering and field sales roles.
Downside: engineering roles are on-site in San Francisco.
Stage: Series B.
4. Efficient Computer
Best for: chip designers, verification engineers and Linux kernel people.
- On September 29, 2026, Efficient Computer announced more than $97M in Series B funding at a $650M valuation, led by TQ Ventures, with Eclipse and Union Square Ventures joining (company release).
- Its Electron E1 processor is in volume production, and the money goes to shipping it and scaling the design to datacenter performance.
- Its Greenhouse board lists 25 roles, 19 of them in engineering, across the Bay Area, Pittsburgh, Austin, Tucson and remote.
Why it made the list: the clearest engineering-heavy hiring plan here, spread over four cities.
Downside: the stack is narrow. If RTL and physical design mean nothing to you, the list is mostly closed.
Stage: Series B, $173M raised in total.
5. Mach9
Best for: ML engineers and people who want to be an early ops hire.
- On October 21, 2026, Mach9 raised a $34M Series A co-led by First Round Capital and Bessemer (TechCrunch).
- It turns 3D scans of roads and job sites into CAD drawings. Nearly 100 customers used the private beta on more than 2,500 projects. Bessemer says the money grows the go-to-market team (Bessemer).
- The job board lists a head of ML, ML engineers, account executives, and a founding recruiting lead and founding people ops lead, mostly in San Francisco.
Why it made the list: two founding-level ops roles. Those titles don't stay open long after a Series A.
Downside: the company dropped robotics hardware for software, so the product is young.
Stage: Series A, $49M raised in total.
6. Restate
Best for: remote candidates in Europe or the US.
- On September 30, 2026, Berlin-based Restate raised a $20M Series A led by Singular, with Redpoint and Capital One Ventures (TechCrunch).
- Co-founder Stephan Ewen co-created Apache Flink. Restate keeps long workflows running through crashes, and Replit is a named customer. The plan is a go-to-market team, more engineers and a bigger Bay Area office.
- The job board lists developer relations, product marketing and a solutions architect (remote US), plus a product designer and design engineer (remote Europe).
Why it made the list: the only company here hiring remote in Europe, and its founders built Flink before this.
Downside: six postings, one of them a general application. Expect a small, picky team.
Stage: Series A.
7. Baba
Best for: clinicians, healthcare operators and growth marketers.
- On October 20, 2026, Baba raised a $40M Series A led by FirstMark Capital, with CVS Health Ventures joining (Fierce Healthcare).
- It pairs Medicare and Medicaid patients with care advocates and says it has supported more than 10,000 patients. Part of the money expands its clinical care teams.
- The job board lists remote virtual physicians and nurse practitioners (some bilingual Mandarin or Spanish), a psychiatrist, and SoHo roles in payer partnerships, revenue cycle and growth marketing.
Why it made the list: proof that funded startups hire far beyond engineering.
Downside: we saw one engineering role. Developers have better odds elsewhere on this list.
Stage: Series A.
What the Clera data shows
These seven are the loud ones. Most startups hiring never make a funding headline. Clera's homepage tracks 5,700+ startups and 1,700+ open roles in the SF Bay Area, and 2,400+ startups and 1,400+ roles in New York. The average Clera candidate gets from signup to a first interview in 8 days. For city-by-city picks, see the best startups in San Francisco and the best startups to work for in NYC.
Our take: half these jobs aren't for engineers
Most lists of startups hiring are lists of engineering jobs. That's not what the boards show. Of the 37 Vinci roles, 21 sit in go-to-market or legal. Armadin's visible roles were mostly sales. Baba's were mostly clinical. If you sell, run ops or treat patients, a fresh round is as much your signal as anyone's.
The other pattern: four of the seven build for the physical world (chips, CAD, roads, hardware simulation). The money this fall is chasing atoms, not just chat.
How to choose
- If you're an engineer who wants the most options, pick Vinci or Efficient Computer. Between them they list 62 roles.
- If you need remote, pick Restate, or the remote clinical roles at Baba.
- If you sell, pick Armadin or Flow Engineering. Both are hiring field reps in several US cities.
- If you want to be early, pick Mach9. Founding ops titles at a Series A are rare.
Pay matters too. Check software engineer salaries at startups by stage before you talk numbers.
Frequently Asked Questions
Watch funding news, then go straight to the company's own job board. Most startups post on Ashby, Greenhouse or Lever, and the board is often more current than LinkedIn. Job boards built for startups help too. We compared them in the best places to find remote startup jobs.
Our view is yes. The weeks after a round are when new seats get approved and budgets are freshest. Apply directly or get a warm intro, and name the round in your note. It shows you did the reading and know why they're hiring.
No. On the boards we checked, more than half of Vinci's listed roles were in go-to-market or legal, and Baba was hiring mostly clinicians. Sales, marketing, operations and specialist roles open right alongside engineering after a round.
Series A gives you broader scope and founding titles, like Mach9's first recruiting lead. Series B usually means more structure, more roles and less risk, like Vinci's 37 openings. Pick based on how much ambiguity you enjoy.
