How we picked
We started from the pages ranking on Google for "startup jobs boston", added the sources from our guides to startup jobs in NYC and startup jobs in San Francisco, and checked each one directly on November 9, 2026. A source made the list if it showed Boston startup roles and we could confirm its facts on its own site.
Two got cut. Underdog.io, which we like in New York and San Francisco, doesn't mention Boston on its homepage. startup.jobs blocked our check, so we couldn't confirm its Boston numbers.
We built Clera, so it gets the same fields and one blunt downside as everyone else. It isn't ranked first.
1. Wellfound
Best for: browsing the largest pool of Boston startup roles in one place.
Wellfound is a startup-focused job board. On November 9, 2026, its Boston page showed 546 results across 10 pages. Most cards show pay, and some show equity, like "$65k to $90k, 0.01% to 0.05%" for a paralegal role. Company cards carry a reply badge: Tierra Climate, a 1 to 10 person startup, showed "Responds within a day", while AssemblyAI showed "Responds within three weeks".
Why it made the list: you see size, pay and reply speed before you spend an hour on an application.
Downside: the Boston page isn't startups only. Page one included Klaviyo, labelled a publicly traded company, and Amazon at 5,000+ employees. Check the size on every card.
Pricing: free for job seekers.
2. Top Startups
Best for: seeing a startup's investors and last round before you apply.
Top Startups tracks startups funded by firms like Sequoia, Y Combinator and Andreessen Horowitz. Its Boston page listed 268 startup jobs on November 9, 2026, and says it updates daily. Each card shows headcount and the latest round, for example Decagon at 11 to 50 employees after a $65M Series B in 2024, or Air Space Intelligence after a $34M Series B in 2023.
Why it made the list: funding is on the card, so you know how much runway you're joining.
Downside: "startup" is generous here. The first six cards included Toast, labelled post-IPO at a $10.0B valuation, and Flock Safety after a Series F. Many roles are also Boston seats at companies based elsewhere, like Harvey and Decagon, so ask where the team actually sits.
Pricing: free to browse.
3. Work at a Startup (Y Combinator)
Best for: applying once to many YC-funded companies.
Work at a Startup is Y Combinator's own job platform. On November 9, 2026, its Boston page showed about 40 roles, from companies like Entangl, Corgi, Vector, SiPhox Health and Zip, with pay ranges like $120K to $180K at Entangl and $180K to $215K for a sales engineer at Vector. You build one free profile and founders can come to you.
Why it made the list: at YC companies, the person reading your profile is often a founder, which cuts out a screening step.
Downside: the Boston page isn't strictly Boston. Several SiPhox roles were in Burlington, MA, Pirouette Pharma was in Portsmouth, NH, and Legion Health roles were remote. It's YC companies only.
Pricing: free.
4. Greentown Labs
Best for: climate and energy people who want to stay in the Boston area.
Greentown Labs is a climatetech incubator in Somerville. Its careers page pulls open jobs automatically from member companies' own career pages and hiring tools, such as Lever, Greenhouse or Ashby, according to its member hiring page. That means the listings are the startups' real openings, not reposts.
Why it made the list: it puts climate startups in one place, while generic boards bury them under insurers and hospitals.
Downside: it's climate and energy only, and it shows no total count, so you can't size the pool at a glance. Member companies can also opt out of the sync, so the feed may miss some.
Pricing: free to browse.
5. Built In Boston
Best for: seeing the whole Boston tech job market, startups and all.
Built In Boston is a city-specific tech job board. It has filters for remote or hybrid, experience, industry, company size and an "Early Applicant" option. Its pagination runs to page 1,000.
Why it made the list: the company size filter turns a citywide board into a startup board in two clicks, and the industry filter covers biotech and healthtech, two areas where Boston is strong.
Downside: on November 9, page one led with Liberty Mutual Insurance (three listings), Optum and Chewy. Skip the size filter and you're not looking at startups.
Pricing: free to browse.
6. Clera
Best for: getting startups to come to you instead of applying one by one.
We built Clera. You spend about two minutes telling Clera what you've done, what you want and your dealbreakers. When a role fits, Clera introduces you directly to the hiring manager with context on why you fit. Our homepage lists 253,073 candidates on the platform and 8 days from signup to first interview.
Why it made the list: a warm intro to the person doing the hiring skips the pile of cold applications.
Downside: Boston isn't one of Clera's big markets. Our homepage only breaks out the SF Bay Area and New York, so if you want an office job in Boston itself, the boards above will show you more. Clera earns its place if you're open to remote roles or a move.
Pricing: free for candidates. Companies pay when they hire.
What's changing in Boston startup hiring
Massachusetts now makes most startups show pay. Since October 29, 2025, employers with 25 or more employees must include a pay range in job postings for Massachusetts roles, including postings by outside recruiters, and applicants have a right to the range when they apply (Mass.gov, Greenberg Traurig). The catch: a 15-person seed startup is under the line. If its posting has no range, ask in your first message.
Public hiring is also getting quieter. The Hacker News "Who is hiring?" thread drew 579 comments in November 2025 and 317 in November 2026, while the November 2026 "Who wants to be hired?" thread drew 562 (whoishiring). Job seekers now post almost twice as often as companies. Our read is that more hiring runs on referrals and intros.
Our take: the pages ranking for this search are all job boards, and every one of them mixes big companies into its Boston results. In Boston it shows fast: Built In's first page is an insurer, a health giant and a pet retailer, and Wellfound's has Amazon. The startups sit in clusters: climate around Greentown, YC companies on Work at a Startup, funded AI companies on Top Startups. Start with the cluster that fits you, then use one big board with a strict size filter.
From Clera's data: widen the net past Boston
Clera's homepage lists 1,700+ roles in the SF Bay Area and 1,400+ in New York, and no separate Boston figure. Across all open roles on Clera, only 14% were fully remote on October 22, 2026, as covered in our remote startup jobs guide. For a Boston job seeker that means two things. Remote startup roles exist but are the minority, so filter for them early. And if you'd consider New York, it's a train ride away, and its 1,400+ roles on Clera come close to the Bay Area's 1,700+.
How to choose
- If you want the most options fast, start with Wellfound and check company size on every card.
- If funding and runway matter to you, use Top Startups and skip anything post-IPO.
- If you work in climate or energy, go to Greentown Labs first.
- If you'd rather write one profile and get messages, use Work at a Startup for YC companies and Clera for remote roles or a move.

Frequently Asked Questions
Wellfound has the biggest pool, with 546 Boston results on November 9, 2026, and pay on most cards. Check company size, since page one includes Amazon and Klaviyo. Pair it with Top Startups, which shows each company's last funding round, or Greentown Labs if you work in climate.
Only if they have 25 or more employees. Since October 29, 2025, Massachusetts requires those employers to include a pay range in postings for Massachusetts roles, and applicants can ask for the range. Smaller startups are exempt from the posting rule, so ask directly if a seed-stage listing has no range.
No. Across all open roles on Clera, only 14% were fully remote on October 22, 2026. Boston boards show the same pattern: most cards are hybrid or in office. If you need remote, set the remote filter on Wellfound or Built In Boston before you start scrolling.
