How to find jobs at YC and early-stage startups before they hit LinkedIn
Some early-stage startups hire quickly and informally, with a founder or small team handling the work themselves. That makes specialist startup boards, founder posts and the company's own careers page worth checking alongside LinkedIn, rather than assuming every vacancy reaches the same channels at the same time.
An early-stage startup can run a smaller, less formal process than a large employer, sometimes with a founder handling the work directly. That can make the hiring decision fast when a credible candidate appears, but the timetable and decision-maker vary by company.
Our time-to-fill article explains why a small hiring team can move quickly once it finds a credible candidate. That does not mean every founder stops at the first good application, but entering before the queue builds gives you a real chance to be considered while the comparison is still open.
The source can differ too. A small company may use a specialist startup board, a founder's post or its own careers page rather than paying for broad distribution. That is why a single general board is not enough for a targeted startup search.
Channel 1: YC Work at a Startup
What it is: Y Combinator's own job board, listing roles at YC portfolio companies (current batch and alumni).
Why it belongs in the search: YC portfolio companies can advertise directly to people already interested in startups. A role may appear here, on the company's own page, on both, or through another channel, so verify the current application route at the source.
How to use it well: use role and location filters, then read the recent listings directly rather than assuming an email alert contains everything relevant.
What you'll miss: roles at startups that aren't YC alumni, which is the majority of seed-stage activity globally.
Channel 2: Wellfound (formerly AngelList Talent)
What it is: the largest job board for early-stage tech roles, with a startup-specific applicant profile that doubles as a candidate database for founders.
Why it belongs in the search: Wellfound focuses on startup employers and can surface young companies that are easy to miss in a broad job-board search. It is another discovery source, not proof that a listing appeared there first.
How to use it well: complete your profile fully (founders search candidate profiles directly), enable "open to opportunities", and follow companies you'd like to work for so you get notified when they post new roles.
What you'll miss: European startups under-index on Wellfound versus US ones. UK-specific early-stage hiring is more visible on Otta and Welcome to the Jungle (formerly Otta merged into WTTJ).
Channel 3: Welcome to the Jungle / Otta
What it is: a European-focused job platform for tech-leaning startups and scale-ups, especially active in the UK and France.
Why it belongs in the search: Welcome to the Jungle includes startup and technology employers in the UK and Europe. Its company profiles can help with discovery, while the employer's own listing remains the place to confirm freshness.
How to use it well: filter by location, stage and role family. Save searches so you get a daily digest.
What you'll miss: US-only and APAC-only startups.
Channel 4: Twitter / X and founder LinkedIn
What it is: an informal channel where a founder or team member can announce a role before a structured advert is ready. Personal posts on LinkedIn or X can therefore be worth following, without assuming every startup hires this way.
Why it can be early: a personal post can be published before the company has prepared a full careers-page listing.
How to use it well: follow 100 to 200 founders in your target sector. Use Twitter Lists or a separate account so the signal isn't drowned in the broader feed. Search for "we're hiring" or "[role] hire" filtered to people you follow.
What you'll miss: founders and teams who do not post publicly, or whose posts never reach your feed. Treat social posts as one route into the market, not a complete index.
Channel 5: "Newly funded" signals
What it is: tracking new funding rounds as a leading indicator of hiring.
Why it can help: funding may precede hiring, but neither headcount growth nor its timing is guaranteed. Treat an announcement as a company-research signal, then verify actual roles at the source.
How to use it: follow Crunchbase and Sifted (for UK and European fundings) and TechCrunch (for US). When a company in your sector raises, look at their careers page even if it currently shows nothing. Set up monitoring (see our piece on monitoring careers pages) so you catch the first roles they post.
What you'll miss: bootstrapped companies and stealth-mode rounds. Not all hiring is preceded by a public funding round.
Channel 6: ATS-direct monitoring
A startup may adopt an ATS as hiring becomes more regular. Ashby, Greenhouse, Lever and other systems can host the public listing; our ATS explainer covers how to recognise a source page from its URL.
Each of these ATSes exposes job postings via reasonably well-structured pages, which makes direct monitoring straightforward. FirstPost monitors all of them, so you can watch startup careers pages without building anything yourself. Try FirstPost free.
Putting it together: the practical workflow
If you're actively looking at early-stage startups, a workable routine is:
- Check recent roles on YC Work at a Startup and Wellfound.
- Check Welcome to the Jungle where it covers your market.
- Scan a focused LinkedIn or X list of founders in your space.
- Check your direct careers-page monitoring for source listings.
Keep the routine short and the company list focused enough to sustain. Our full daily routine covers how to move from discovery to a strong application without giving away the source-first timing advantage.
The CV and outreach mechanics for early-stage
In a small hiring process, a founder or team lead may read applications directly. Make three signals easy to find:
- Specific evidence of doing the job. Not "led engineering team" but "shipped X with team of Y over Z months". Specificity reads as credibility.
- Engagement with their company. One line in your application that demonstrates you've actually used the product, read the blog, understand the customer. Not flattery; substance.
- Low downside. Early-stage hires are high-trust bets. Anything that signals reliability (long tenure at previous roles, evidence of finishing things, no obvious red flags) compounds.
The realistic picture
Early-stage hiring can be faster and more informal than an enterprise process, so a search built around one general job board may miss openings. Some roles never appear on LinkedIn or arrive there after another channel. If you care about this part of the market, check YC Work at a Startup, Wellfound, Welcome to the Jungle, relevant founder posts and the company's own careers page.
Keep the company list small enough that you can check it without turning the routine into a second job. Our guide to applying early covers the broader approach; the YC and Wellfound routes here apply it to startup hiring, where a small team may move before a general board catches up.
