Five companies closed Series B or C rounds in the last two weeks, and every one of them has open roles on its careers page today. If you’re looking for companies hiring in October 2026, this is a better list to start from than a job board, because each name comes with a reason the hiring is happening and a guess at who owns it.
A funding announcement works as a hiring plan published in advance. The money is raised against a headcount budget, and the people who own that budget start interviewing before every role is posted. Below: what each company announced, why it points to hiring, the title most likely to own the hire, the open roles as of October 2, and a first message you can adapt.
The owners are listed by title only. Finding the actual person is your job, and the last section covers how.
Numeral: $100M Series C and a sales team to build
Numeral, a San Francisco sales-tax compliance platform, raised a $100 million Series C led by Insight Partners, reported by Pulse 2.0 on September 23. Total funding is now $157 million.
The announcement says outright that the money “will support product development, expansion into additional industries, international growth, and hiring across engineering, sales, marketing, and product teams.” The same report puts year-over-year growth in transaction volume at 327%. Volume like that needs account executives to sell it and implementation people to onboard it.
Likely owner: VP of Sales.
Open roles as of October 2, 2026: 24 on the Numeral careers page. Sales is the biggest group at 8, including Commercial, Mid-Market and Enterprise Account Executive roles, plus partner managers focused on accounting firms. Engineering and product account for 6, operations 4, finance 2.
The angle: “Expansion into additional industries” means new verticals with nobody selling into them yet. If you’ve sold software to one of those buyers, lead with that.
Hi [Name], congrats on the Series C. The announcement mentioned expanding into new industries, and I’ve spent four years selling finance software to mid-market SaaS controllers, the people who usually own sales tax. I’d like to hear which verticals are first and whether the Mid-Market AE role covers them.
Miter: $40M Series B, engineering in New York
Miter, which builds payroll and workforce software for construction companies, announced a $40 million Series B led by Battery Ventures on September 30, per its release on Yahoo Finance. It has raised $78 million in total.
The release names where the hires go: Miter “will also significantly grow its engineering team based in San Francisco and New York and add to its go-to-market teams across the U.S.” It also says customer count has tripled since the Series A in May 2025. More customers on a payroll product means more engineering load, since payroll can’t break.
Likely owner: VP of Engineering.
Open roles as of October 2, 2026: 14 on the Miter careers page. An Engineering Manager role in New York City went up on September 28, two days before the announcement, alongside a new-grad software engineer opening in New York. Sales has 8 roles, among them a Regional Sales Manager for the Northeast and an Account Executive in Atlanta.
The angle: An Engineering Manager posted right before the raise usually means a new team is being formed, and whoever runs engineering decides what it owns. Ask what the New York team is for before you pitch yourself into it.
Hi [Name], saw the Series B and the plan to grow engineering in New York. I’ve spent three years on payroll and time-tracking systems where an off-by-one in overtime logic becomes a support ticket from every crew lead. What will the New York team own first?
Rainmaker: $100M Series B for an atmospheric research lab
Rainmaker Technology, an El Segundo company that seeds clouds with drones to add rain and snow, announced a $100 million Series B on September 21. Coverage came from RuntimeWire and VC News Daily. The company didn’t name a lead investor.
RuntimeWire reports that Rainmaker “plans to hire atmospheric scientists, radar and satellite specialists, aerosol researchers and materials scientists.” The round is meant to grow the research organization, and research organizations grow by adding people.
Likely owner: Head of Research (or Chief Scientist).
Open roles as of October 2, 2026: 25 on the Rainmaker careers page, all posted or refreshed this week. R&D leads with 8, including Machine Learning Researcher and fellowships in radar science, atmospheric science and satellite remote sensing. Growth has 7, mostly business development directors for California, Utah, water, agriculture and international work. Engineering has 4.
The angle: The science roles exist to answer one question: did the seeding actually produce the extra precipitation? Bring evidence that you can measure an effect in noisy environmental data.
Hi [Name], read about the Series B and the research hiring. My graduate work was radar-based precipitation estimation, mostly separating real signal from storm-to-storm noise, which looks like the hard part of proving seeding works. Is that measurement problem what the radar science fellowship is for?
Tiny Health: $33M Series B and a push into clinics
Tiny Health, an Austin company selling at-home gut microbiome tests, raised a $33 million Series B led by B Capital, MedCity News reported on September 29. It has raised $46 million in total.
Per MedCity, the money goes to “clinical research and interventional studies, expanding healthcare practitioner education and advancing its AI technology.” The company reports serving nearly 200,000 customers and more than 6,000 healthcare practitioners. Teaching more clinicians to use the product is a marketing and account-management job before it’s anything else.
Likely owner: VP of Marketing.
Open roles as of October 2, 2026: 20, plus a general application, on the Tiny Health careers page. Almost all are remote within the US. Marketing has 4, including a B2B Marketing Lead for practitioners and enterprise and a Lifecycle Marketing Manager. Science has 6, and clinical success has 4 account managers covering pediatrics, longevity and territories. A VP of Engineering role is also open.
The angle: Practitioner education is the most specific use of funds in the announcement. If you’ve marketed a product to doctors, dietitians or pediatric practices, that’s the one thing to put in your first line.
Hi [Name], congrats on the Series B. MedCity mentioned expanding practitioner education, and I ran a clinician education program for a diagnostics company that grew from a handful of pilot practices to a few hundred. Is the B2B Marketing Lead role where that program will sit?
Quartermaster: $140M Series B for maritime sensing
Quartermaster, based in Arlington, Virginia, puts camera and radio sensor packages on ship masts to track activity at sea. It raised a $140 million Series B preempted by Insight Partners, TechCrunch reported on September 28. About $100 million is equity and the remaining $40 million is a debt facility from Stifel. The round comes four months after a $43 million Series A.
TechCrunch notes that the company has doubled its manufacturing capacity and sells to governments, shipping companies and insurers. Two rounds in four months mean the plan has gone from proving the hardware to deploying it on many more ships, and fleet rollouts depend on contracts, program managers and field operations people.
Likely owner: VP of Government Programs.
Open roles as of October 2, 2026: 16 on the Quartermaster careers page. Engineering has 8, including RF systems and applied machine learning. Recent non-engineering postings include a Contracts Manager for Government Programs, two Technical Program Managers, Head of Launch roles for Europe, Africa and the Middle East, and a VP of Supply-Fleet Recruitment in New York.
The angle: The contracts and program roles went up in the week of the raise. If you’ve worked through federal acquisition or managed a hardware program for a defense customer, say that before anything else.
Hi [Name], saw the Series B and the new Contracts Manager role for government programs. I’ve spent five years on federal hardware contracts, mostly getting pilot deployments converted into production orders. Is that pilot-to-program step the bottleneck now?
Companies hiring in October 2026: find the person before you apply
Every company on this list posted roles because a budget opened, and that holds for most companies hiring in October 2026 after a raise. The person who owns that budget gets the same flood of applications as everyone else, and a short, specific note tied to the announcement is one of the few things that stands out in it.
Here’s the workflow for any company on this list:
- Start from the title, then confirm it. “Likely: VP of Sales” is a hypothesis. Search the company’s people on LinkedIn for that function and look for whoever posted about the round or the new roles. The press release quote often comes from the right executive.
- Read what they’ve said recently. A podcast, a post about the raise, a talk. One specific reference beats any amount of flattery. The guide to researching a hiring manager walks through this step by step.
- Find a working email. LinkedIn messages from strangers get buried. The method for finding and verifying a hiring manager’s email takes about ten minutes per person.
- Send three sentences, then apply. Mention the signal, the overlap with your work, and one question. Send the application the same day so your name is in their applicant tracking system when they go looking.
The sample openers above are templates, so swap in your own experience. They all follow the same pattern: one line on the news, one line of proof, one question the person can answer in a sentence. None of them asks for a job, which is why a busy person might actually answer.
This is direct outreach, and it works better than a blind application for a simple reason: the hiring manager hears about you before the recruiter’s shortlist exists. The hard part is the legwork: finding the right person, reading up on them and writing something that doesn’t sound generic. angld.AI does that research for you. Paste a job posting and it identifies the likely decision maker, researches them and drafts a personalized message in about a minute.
