Okay, let's tackle this. The user wants a job title that's both SEO-optimized and naturally appealing. The main points are: Chef de Ligne H/F, Team.is, Portes-lès-Valence, CDI.
First, I need to keep it under 60-70 characters. Let me check the example they gave. The sample title is "Chef de Ligne H/F - Team.is - CDI - Portes-lès-Valence". That's 56 characters. Wait, the user said 60-70 max, so maybe a bit longer is okay. But the example is within that range.
Now, the user emphasized no quotes, no intro or conclusion, just the title. So I need to make sure there's no markdown. Also, the title should be natural, like a human recruiter would write.
Let me think about keywords. The main keyword is "Chef de Ligne H/F". Then the company name Team.is, the location Portes-lès-Valence, and the contract type CDI. Including these should help with SEO.
Maybe structure it as "Chef de Ligne H/F - Team.is - CDI - Portes-lès-Valence". That's concise and includes all necessary info. Let me count the characters. "Chef de Ligne H/F - Team.is - CDI - Portes-lès-Valence" – that's 56 characters. Perfect, within the limit.
Alternatively, could I add something about the company's strengths? The description mentions it's a human-sized company, passionate about recruitment, and has expertise. But adding that might exceed the character limit. The user might prefer brevity for SEO.
Stick to the essentials: position, company, contract, location. That's standard in job titles and SEO-friendly. Avoid fluff. The example they provided is exactly that. So I think that's the way to go.
