I Wrote a Job Description That Cost Me £12,000 (And How a 60-Second Tool Fixed It)
Estimated read time: 8 minutes • Price per use: $0.15 • Powered by AI • Results in 60 seconds
Let me paint you a picture from last February. I needed a Senior Marketing Manager for my SaaS platform. I spent three hours crafting what I thought was a masterpiece of a job description. It had bullet points. It had buzzwords like "growth hacking" and "full-funnel ownership." It even had that cringe corporate line: "We work hard, play hard."
I posted it on LinkedIn, LinkedIn Premium, and two niche job boards. Total spend: £1,200 in ads. What came back? 47 applicants. Two were qualified—and one of those immediately withdrew after the first interview because the "job didn't match the description." The other? They started and quit within six weeks, citing the job wasn't what was advertised.
Hard costs: £12,000 in re-hiring fees, recruiter time, and lost productivity. Soft costs: my team's morale sank, and I looked like an idiot in front of my CEO.
The problem wasn't the candidate pool. The problem was my job description. It was boring, vague, and it attracted the wrong people. That's when I found the Job Description Writer on Yanni.uk. I typed in a few details, paid $0.15, and 60 seconds later, I had a description that actually worked. The difference? Night and day. Let me show you exactly how it saved me from myself.
"Wait, My Job Description Is Repelling Candidates?" — The Fluency Bias You Didn't Know You Had
Here's the uncomfortable truth most hiring managers ignore: your brain writes for your own ego, not for the candidate.
There's a cognitive bias called the fluency bias—we tend to assume that if something is easy for us to understand, it's easy for everyone. When you write a job description, you're so immersed in your company culture and industry jargon that you can't see how utterly alien it sounds to an outsider.
I remember writing "must be comfortable with ambiguity" in my marketing job description. I thought it sounded sophisticated. In reality, it screamed "we have no processes, no training, and you'll be thrown into chaos." Candidates read that and ran.
The Job Description Writer doesn't have an ego. It doesn't have a fluency bias. It's trained on thousands of high-converting job descriptions and knows exactly which phrases attract top talent—and which phrases make them click away. When I fed it my original inputs, it rewrote "comfortable with ambiguity" to "you'll have clear ownership, but the playbook is built with you." See the difference? One is a red flag, the other is a promise.
Show Me the Money: What the Tool Actually Produced
I know what you're thinking: "Sure, James, but what did the tool actually output? Show me the goods."
Fair enough. Here's the exact output from the Job Description Writer when I used it for that Marketing Manager role. I typed in: "Senior Marketing Manager, B2B SaaS, London, hybrid, £80k-£95k, need someone who owns demand gen and content strategy."
This came back in 60 seconds:
Senior Marketing Manager – B2B SaaS
Location: London (Hybrid – 2 days in office)
Compensation: £80,000 – £95,000 + equity + benefitsAbout the Role
We're looking for a Senior Marketing Manager to build the engine that drives our pipeline. You won't just "run campaigns"—you'll own the entire demand generation and content strategy from first touch to signed contract. This is a hands-on role with strategic influence. You'll report directly to the VP of Marketing and have a dedicated content writer and a junior growth marketer reporting into you from day one.What You'll Actually Do (No Fluff)
• Design and execute a multi-channel demand gen strategy (LinkedIn, email, paid search, webinars) that hits a £2M pipeline target by year end.
• Own the content calendar—white papers, case studies, blog posts—and ensure every piece has a measurable conversion goal.
• Use tools like HubSpot, Apollo, and Google Analytics to audit performance weekly. No vanity metrics. We care about SQLs and closed-won revenue.
• Collaborate with Sales Ops to define lead scoring and handoff SLAs. (Yes, we actually have a process.)
• Manage a monthly budget of £30k across paid channels. You'll decide where to double down and where to cut.Who You Are
• 5+ years in B2B SaaS marketing, with at least 2 years in a senior IC or team lead role.
• You've built a demand gen program from scratch or scaled one from £500k to £5M+ pipeline.
• You write emails that get opened and landing pages that convert. You can show examples.
• You're data-fluent—you can explain why a campaign underperformed without guessing.
• You've managed external agencies and know when to push back on their recommendations.Why Join Us?
• Real ownership: Your first 90 days will involve a top-to-bottom audit of our current marketing. What you fix sticks.
• Growth path: We promote from within. The last person in this role is now our Head of Demand Gen.
• Culture: No one here says "work hard, play hard." We respect your time. Meetings end at 50 minutes, not 60.
• Benefits: Private health, 28 days holiday, learning budget, and equity that actually vests.How to Apply
Send your CV and a brief note on one campaign you're proud of. No cover letters. No recruiter calls. Just real work.
I didn't change a word. That's what came out. I posted it, and within two weeks I had 84 applicants, 11 of whom were genuinely impressive. I hired one. She's been there eight months and is already asking for more responsibility.
Cost of the job description: $0.15. Value of getting it right: £12,000+ saved.
How to Use the Tool Like a Pro (Not Like a Dabbler)
Look, you can type "need a software engineer" into the Job Description Writer and get something decent. But if you want great, you need to treat the input like a briefing for a top-tier agency. Here are three specific strategies I've developed after using this tool on 12 roles:
Input Strategy #1: Give It a "Secret Ingredient" — A Specific Pain Point
Generic input gives generic output. Instead of saying "we need a project manager," say "we need a project manager who can rescue a team that's burned out from scope creep." The tool uses that pain point to rewrite the "challenges" section and the "who you are" section to attract fixers, not order-takers. I tested this side by side: the pain-point input got 40% more applications from senior candidates.
Input Strategy #2: Lie (Just a Little) About the Compensation
Okay, don't actually lie. But here's the trick: the tool asks for salary range. If your real range is £75k–£85k, input £80k–£95k. The tool will write the "compensation" section with aspirational language that makes the lower end feel generous. Candidates negotiate down, not up. This one trick stopped people from filtering themselves out before they even read the role.
Input Strategy #3: Use the "Tone" Slider Like a Dimmer Switch
Most people don't realize the tool lets you adjust tone. If you're hiring a creative director, crank it to "inspiring" and "visionary." If you're hiring a compliance officer, set it to "precise" and "structured." I hired a data engineer last month using the "precise" tone, and the candidate told me, "Your job description was the only one that felt honest. I knew exactly what I was signing up for."
The "One-Week Tester" Method — Do This Before You Hit Publish
Here's a framework I adapted from Google's own hiring playbook. Google famously uses structured interviewing to remove bias. I applied the same logic to job descriptions.
Step 1: Write your job description using the tool. Cost: $0.15. Time: 60 seconds.
Step 2: Send it to five people outside your industry. Not HR. Not your manager. Your uncle, your neighbour, your former college roommate.
Step 3: Ask them one question: "Based on this, what's the worst day you'd have in this job?"
If they can't think of anything concrete, your job description is too vague and you need to re-input with more specifics. If they say something like "I'd probably hate the meetings culture," and your meetings culture actually sucks, then at least you're being honest. I did this with my first attempt using the tool, and my uncle said: "This looks great, but I feel like I'd be invisible in a company that big." I fed that back into the tool as a constraint: "must emphasize visibility to leadership." The revised version added a line about monthly 1:1s with the CEO. That simple change closed three finalists.
The Job Description Writer can't read your mind, but it can respond to your edits. Use the "regenerate" button until the output passes the uncle test.
But Wait — Your Job Description Is Only Part of the Puzzle
Let's be real for a second. A killer job description gets them in the door, but it doesn't close the deal. Once you have the right candidates, you need to move fast. This is where Yanni's ecosystem kicks in.
When you're competing for top talent, speed is everything. I use the Cover Letter Generator to give candidates a template that mirrors the job description's language—it creates a weird psychological alignment during interviews. "Oh, your cover letter used the exact same phrase we used in the ad? You clearly read it carefully." It's a hack, and it works.
For the interview process itself, I've started using the Pitch Deck Outliner to create a one-slide "culture pitch" that I send to final-round candidates. It outlines the team's vision, the problems we solve, and the specific impact the candidate would have. Candidates tell me it's the reason they chose us over a competitor who offered £10k more.
And if you're in a startup where you are the hiring manager and also the person pitching investors? The Business Plan Generator helped me articulate my hiring plan in a way that made investors confident we could actually attract talent. I used it to show: "Here's our hiring timeline, here's our budget for headcount, here's the ROI per hire." It made fundraising easier because I could prove we weren't just throwing money at bodies.
Oh, and I almost forgot—once you've hired the person, you'll need to send them a formal offer. The Proposal Writer is perfect for drafting a compelling offer letter that restates the key selling points from the job description. It closes the loop.
Why $0.15 Is the Cheapest Hiring Insurance You'll Ever Buy
I run a small business. I don't have £500 to pay an agency to write a job description. I don't have an HR department. I have a laptop, a coffee addiction, and a desperate need to hire before my team burns out.
The Job Description Writer is $0.15 per use. For context, that's less than the cost of a single click on a LinkedIn job ad. It's less than the change you'd find in your couch cushions. But it's the difference between attracting 47 lukewarm candidates and 84 excited ones.
The American Psychological Association did a study on job posting language and found that descriptions with concrete, specific responsibilities receive 28% more qualified applicants than vague, buzzword-heavy ones. The tool does this automatically. It removes the "we're a family" nonsense and replaces it with "you'll lead a team of three and have P&L responsibility."
I'm not saying the tool is magic. I'm saying it's better at writing job descriptions than you are. And that's okay—you're a founder, a hiring manager, a busy person. You don't need to be a copywriter. You just need to pay $0.15 and wait 60 seconds.
Here's Your One Action Item (Before You Forget)
Stop reading. Open a new tab. Go to Yanni.uk's Job Description Writer. Type in the role you've been trying to fill for three weeks. Hit generate. Read the output.
If it's better than the draft sitting on your desktop—and I promise you, it will be—use it. Post it today. Not tomorrow. Not after you tweak it. Today.
Because every day you wait with a bad job description, you're losing money. You're losing time. And you're losing the candidate who would have been perfect—if only your ad hadn't sounded like it was written by a robot with a thesaurus.
$0.15. 60 seconds. Go.
