<think> Okay, let me tackle this job description cleanup. First, I need to make sure I follow all the user's instructions carefully. The main goal is to preserve the original structure and wording of the job description while cleaning up the markdown formatting.

Starting with the page content, I see that there are several sections like "Your Mission," "What We're Looking For," etc. But looking at the provided content, the actual sections are labeled differently. For example, the company info is under "🌀 The Company," which I need to keep as-is. The user mentioned not to add a separate "About Us" section if the company info is already present.

Next, the formatting rules: use ### for section headings instead of ## or #. So I need to check each heading and adjust them accordingly. Also, bullet points should use - instead of

• or * and numbered lists. The original uses - for bullets, so that's okay.

I need to remove any markdown that's not part of the job description, like the navigation links, headers, footers, cookie banners, and the "Apply Now" button. The page content has some links like and , which should be stripped out. Also, the reCAPTCHA and legal disclaimers at the end need to be removed.

Looking at the sections, the user mentioned that if the description starts with company info, keep it as-is. The original starts with "🌀 The Company" which is part of the job description, so that's okay.

Now, going through each section:

1. Location, Employment Type, Location Type, Department: These are part of the job details, so they should remain but formatted correctly. The user didn't mention removing these, so they stay as they are.

2. 🌀 The Company: This is the company info, so keep it. The user says to preserve the original wording, so no changes here.

3. 🎯 The Role: This is the job title and role description. The original uses "##" for headings, which should be changed to "###". Also, check for bold text and ensure it's formatted with **.

4. 💼 Your Responsibilities: The original uses bullet points with -, which is correct. However, the first bullet has Full Stack Architecture and Typescript and Python. Need to ensure that bold is properly applied.

5. 🤝 Who You’ll Work With: Same as above, check for correct formatting.

6. 🧬 Profile We’re Looking For: The original has bullet points and bold text. Ensure that the bold is correctly formatted and that the section headings are changed to ###.

7. 🛡️ About XTM One: This is a section about the product. Check the heading and formatting.

8. 🌱 Why Join Filigran? More than just a job.: The original has a heading with **, so adjust to ### and ensure bold is correct.

9. 💰 Compensation & Benefits: Section heading, adjust to ###.

10. 🌍 Equal Employment Opportunity: Section heading, adjust to ###.

11. 🚀 Ready to Join Us?: This is the apply section, which the user wants removed. So delete that part.

Also, check for any duplicate content. For example, the title "Senior Software Engineer (TypeScript and Python) - XTM One" is at the top, but the user says to keep it if it's part of the description. However, the user mentioned to remove the title if it's repeated in the body. Wait, the original page content starts with the title, then the sections. The user's instruction says to "strip navigation, headers, footers, cookie banners, and other page chrome" but the title is part of the job description. So I think the title is okay, but need to check if it's duplicated elsewhere. In the provided content, the title is at the top, then the sections start with "## Location" etc. So the title is not duplicated, so it's safe to keep.

Now, applying all these changes, I'll go through each section, adjust the headings to ###, ensure bullets are -, check for bold, remove any markdown that's not part of the job description, and delete the "Apply Now" section.

Also, the user mentioned to remove "Apply Now" buttons, social links, legal/EEO/GDPR disclaimers, AI hiring notices. The last section "🚀 Ready to Join Us?" includes the apply link and the reCAPTCHA notice. Those should be removed.

Finally, ensure that the entire content is in markdown format without any JSON or code blocks, just the formatted description. </think>
