Quick answer: Open Field is a free job search for marketing roles at US brands, from manager up to CMO. It comes from Peregrine Intelligence and runs on the same daily sweep that powers their paid Harrier tool. What sets it apart from a regular job board is context. Every listing is tagged with what kind of seat it really is (a new build, an agency takeover, a top seat, a growing team), and some show a "why now" note such as a recent funding round. No account is needed to search, and job alerts are free.
What Open Field actually is
Most job boards answer one question: does this role exist? Open Field tries to answer the next one too: what is this job, really, and why did it open this month?
Roles are collected every day from company career pages and job boards, and the site says it leaves out staffing agency reposts. When we checked on October 1, it was tracking 79 open roles from the last 31 days, 51 of them new that week. About 20% were VP level or above. B2B SaaS led with 35 roles, followed by DTC/CPG (18), agencies (10) and financial services (5). Most apply buttons go straight to the company's own hiring page, usually on Greenhouse, Lever or Ashby. Of the 60 listings we checked, 53 did, and the other 7 pointed to job aggregators such as ZipRecruiter or Glassdoor.
The role types are the best part
Each listing carries one of six labels:
- Build role: the company is bringing work in house and needs someone to set it up
- Takeover role: you would be replacing a named agency
- Channel owner: you run a channel yourself or manage the agency that runs it
- Top seat open: the head of marketing job
- Senior seat open: a leadership role just under the top
- Growing team: an existing team adding headcount
This sounds small, but it changes how you read a posting. A "Takeover role" means you walk in with an agency relationship to unwind and probably a budget that already exists. A "Build role" means you are starting from a blank page. Two jobs with the same title can be completely different weeks of work, and Open Field makes that visible before you even click.
Open any listing and a "What this means for you" panel explains the role type in plain words, says who it suits, and gives you questions to ask in the interview. For a Growing team role, it suggested asking "What will this role own that no one owns today?" That is a genuinely good interview question, and most candidates would not think to ask it.
Field notes: an AI read of the market
At the top of the results sits a short AI summary of what changed in the market that week. Ours had three notes. Remote marketing roles had jumped to 22 newly tracked, compared with just 1 the week before. Brand side hiring had widened to 22 open roles. And a brand called On had eight marketing seats open at once, which the note pointed out lets you pitch yourself across several openings in one conversation. Each note has a button that filters the list to exactly those roles.
The Market pulse sidebar backs this up with numbers: work style split (64% remote, 20% hybrid, 16% onsite among postings that state it), most named tools, and top industries. Tap any of them and the list filters.
Use cases where Open Field really helps
1. Senior marketers looking for CMO, VP and marketing director jobs. If you are a director or VP, the Top seat and Senior seat filters cut straight to the jobs that matter.
2. Agency people who want brand marketing jobs. Filter for Takeover or Build roles. These are the jobs where your agency experience is the exact thing the company is buying, and you can say so in your cover letter.
3. Anyone searching for remote marketing jobs. The work style filter and the weekly remote trend note make it easy to see whether the remote market is opening up or drying up, so you know when to push harder.
4. Interview prep. Before a first call, look the role up in Open Field. The role type, the funding note and the suggested questions give you a sharper read on the company than the job description alone.
5. Specialists in a particular stack. If you are strong in HubSpot, Google Ads or Meta Ads, the Tool filter shows roles that name it.
6. Passive candidates who want free job alerts. Not actively looking? Set up an "Ear to the Ground" alert, choose a daily email or a weekly one every Monday, and filter it by keyword, industry, role type and tool. Sign up with Google and the alert starts right away.
7. Agencies and consultants looking for new clients. Open Field shows who is hiring. Harrier, Peregrine's paid tool built on the same daily sweep, shows what that hiring means for an agency: which brands are bringing work in house, which have a gap their agency used to fill, and which postings name the agency being replaced. It also tracks how far a brand has drifted from its current agency, matches hiring with funding rounds and leadership changes, and sums up the patterns with AI. Every signal links back to its source. We tested it in our Peregrine OS review.
A few things that could be better
Open Field is still new, so its pool is small for now: 79 roles when we checked. That makes it a sharp second source next to LinkedIn rather than your only job search, and narrow filters such as Tool return only a few roles today. The pool is filling out quickly, though. 51 of those roles were new that week, and coverage should keep widening as the daily sweep runs. For a free product this young, that is a fair trade.
Verdict
Open Field is one of the more thoughtful free tools we have seen for marketing job seekers. It does not try to be the biggest job board. It tries to be the one that explains the job, and it does that well. The role types, the funding notes and the interview questions turn a list of openings into something you can actually act on. If you work in marketing at manager level or above in the US, it costs nothing to add to your search, and the weekly alert is an easy way to keep an eye on the market without checking every day.
