Is the job from Firewatch real?

I've been seeing a lot of posts about a job opportunity from Firewatch, but I'm not sure if it's legitimate. Can you tell me if this job is real? I've heard mixed reviews, and I don't want to waste my time applying for something that might not even exist. Is there a way to verify the authenticity of this job posting? I'm looking for a reliable source of information to help me make a decision.
