Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Use the monthly/biweekly sticky for job posts; external-link posts often hit the spam filter — message the mods if your post disappears.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: question, discussion, news
Headline: short, direct question or descriptive statement (e.g., “How do you…?”, “Is X worth it?”). Write in first person for personal/career posts. Typical length: medium posts (~200–800 words) with a TL;DR and concrete details. Tone: professional, pragmatic, slightly informal. Upvoted: honest career questions, plant anecdotes, data/visuals, practical advice. Removed/downvoted: obvious ads/recruitment, homework dumps, off-topic student posts.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked July 2026. Rules change and moderators have the final say: verify at r/chemicalengineering's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
