What Jobs Are YC Startups Hiring For? We Counted 6,419 Postings

Data as of October 26, 2026 · we update this analysis monthly

Cite as: udreamjob.com, "What Jobs Are YC Startups Hiring For?", October 2026: in a snapshot of 6,419 open postings on the public job boards of Y Combinator companies, 30.8% were engineering and 69.2% were something else. This is our own analysis, not official Y Combinator data.

"Startup job" usually conjures a hoodie, a laptop and a codebase. The postings tell a different story. We counted the open roles at YC companies, and engineers are the single biggest group but nowhere near a majority.

If you are not a developer, that is good news, with caveats. This guide shows which roles startups hire most, which levels they hire at, and how to read the numbers honestly, including the fact that one huge employer inflates the totals.

What Jobs Are YC Startups Hiring For?

Engineering leads, but it is under a third of the total. In our October 26, 2026 snapshot of 6,419 distinct open postings, engineering had 1,979 (30.8%), sales 1,155 (18.0%) and operations 552 (8.6%). Everything else was spread across nine other categories.

Quick Answer: Of 6,419 open postings at YC companies on October 26, 2026, 30.8% were engineering and 69.2% (4,440) were not. Sales was the biggest non-engineering group at 18.0%, then operations at 8.6%. Only 3.9% of postings were junior-level.

Here is the full breakdown, with shares calculated from the counts.

Source: our analysis of public job boards of YC companies, snapshot October 26, 2026. Roles are inferred from job titles. Shares may not sum to exactly 100% because of rounding.

Do Startups Hire Non-Engineers?

Yes, and in volume. 4,440 of the 6,419 postings (69.2%) were outside engineering, and sales, operations, marketing, customer, product, finance and legal, design, people and healthcare roles together made up 3,519 (54.8%). Data and ML adds 417 more (6.5%) if you count it as technical.

Put another way, about 62.7% of postings were neither engineering nor data and ML. The "other" bucket (504 postings, 7.9%) holds titles our classifier could not place, so it is real hiring we cannot label.

Which Non-Technical Jobs Do Startups Hire Most?

Sales by a wide margin, then operations. Sales had 1,155 postings, about 58 for every 100 engineering postings. Operations followed with 552, then marketing (381), customer roles (358) and product (287).

Sales plus customer roles together came to 1,513 postings, or 23.6% of everything we counted. In our read, that matters for career-changers: these are the functions where startups most often need people who can talk to customers, and that skill can transfer from retail, hospitality, teaching and similar fields. That is our interpretation, not something the data measures.

What Seniority Do YC Startups Hire At?

Mostly mid-level and up. Mid-level titles were 2,812 postings (43.8%) and senior 1,414 (22.0%). Junior roles were 248 (3.9%) and internships 134 (2.1%).

Combined, junior and intern roles were 382 postings, about 6.0%. Startups mostly want people who can contribute quickly. Because levels are inferred from title keywords, the "mid" bucket may include titles that simply do not state a level.

One limit: we did not cut role by seniority, so we cannot tell you, for example, how many junior postings are in sales versus engineering. For help competing at the entry level, see our entry-level job-search playbook.

Which Industries Are YC Startups Hiring In?

B2B dominates. B2B companies accounted for 3,682 postings (57.4%), Fintech 1,195 (18.6%), Healthcare 629 (9.8%) and Industrials 487 (7.6%). Consumer was 205 (3.2%), with Real Estate and Construction, Education and Government each under 2%.

Industry comes from each company's industry label in the YC company directory, so all of a company's postings inherit one label. A sales role at a B2B software company and an engineering role there both count as B2B.

Are These Startups or Scaleups?

Both, and you should know the difference. By headcount, 4,048 postings (63.1%) were at companies with 200 or fewer people, which we call startups, and 2,321 (36.2%) were at companies with 201 or more, which we call scaleups. Another 50 postings had no size data.

By team-size band: 201+ people had 2,321 postings (36.2%), 11-50 had 1,752 (27.3%), 51-200 had 1,595 (24.8%) and 1-10 had 701 (10.9%).

Who Is Hiring the Most? (A Scaleup Caveat)

Stripe had 620 open postings, by far the most. Next were Legora (195), Astranis (146), Flexport (115), Spur (103), TRM Labs (98) and Gusto (96). The top 15 companies combined had 1,894 postings, about 29.5% of the total.

Be careful reading that list as "where startups hire." Stripe alone is 9.7% of all postings and is far larger than an early-stage startup. The top-hiring list reflects scale, not startup hiring behavior, which is why we report the startup and scaleup split above.

How Many of These Jobs Are at AI Companies?

About 38.1% of postings came from companies we flag as AI-focused. That flag is applied at the company level in our dataset, so it says where a posting sits, not that the job itself involves AI.

If you are targeting AI companies without an engineering background, the same pattern holds: our flag does not tell us the role split inside those companies, so check each company's board. For pay by role and the AI-company premium, see our YC startup salary report; we deliberately keep pay out of this post.

What Does This Mean If You Are Changing Careers?

Look at the function, not the "tech" label. With 69.2% of openings outside engineering, a career-changer from sales, operations, customer service, marketing or finance has plenty of postings that match their background, but few are junior, so lead with relevant experience.

Three practical moves, all our recommendations rather than findings from the data:

1. Match your past work to a role group. Retail or hospitality experience maps to customer and operations roles; teaching maps to customer success and people roles.
2. Show skills, not just titles. Our guide to skills-based hiring covers portfolios and assessments for people without the "perfect" background.
3. Fill a gap deliberately. If a role wants tools you lack, online courses for switching careers can help close it.

How We Got These Numbers

Method box. We analyzed 6,419 distinct open postings on the public job boards of YC companies, snapshot October 26, 2026. The company list comes from the yc-oss directory mirror, and jobs come from each company's public job board on Ashby, Greenhouse or Lever.

Here is exactly what that means, and where it falls short.

• Coverage is partial. We probed 1,503 YC companies and resolved 452 job boards (358 Ashby, 66 Greenhouse, 28 Lever). 437 of those companies had open jobs. YC companies on other applicant systems, or whose boards we could not match, are missing.
• Distinct postings. We count one posting per company and location-agnostic title. Catch-all "General Application" listings are excluded. The raw listing count was 7,617 before de-duplication.
• Role and seniority are inferred. We classify each posting from its title, so some are misplaced, and 504 sit in "other."
• A snapshot, not a trend. These are open listings on one day. We make no claims about growth or decline.
• Not official. This is our own analysis of public boards, not data from Y Combinator.
• Large employers skew it. Scaleups hold 36.2% of postings, and Stripe alone is 9.7%.

The Bottom Line

YC startups hire far beyond engineering. In our snapshot, 69.2% of 6,419 postings were non-engineering, sales was the largest of those at 18.0%, and only about 6.0% of postings were junior or internship roles. If you are changing careers, aim at the function that fits your experience, and treat the big-company totals with caution.

We will refresh these numbers monthly. Next, see our YC startup salary report for what these roles pay.
