Week of 26 Oct · 20 ideas · Updated every Monday

20 LinkedIn post ideas for engineers, this week.

Ideas for mechanical, civil, electrical, chemical and plant engineers, each with an opening and why it works. Write them yourself, or let Wiri write them in your voice.

How Wiral helps engineers
Idea of the week01Opinion

A clear stance backed by one specific clash. Designers and site people both have a view, so the comments fill up fast.

The post on the right is one way to write it. Yours will be your story.

I’ve stopped approving drawings I haven’t walked. Last spring we issued a revised layout for a pump skid. It was clean on screen. Every clearance checked, every line reviewed by two people.…

Checking vendor drawings line by line

Y
You
Engineer
Now ·
I signed off a vendor drawing after a ten-minute look. The flange rating was one class lower than our spec. We found out when the pipe arrived.

Why it works: A rushed sign-off with a real cost makes readers check their own habits.

03Opinion

Not every slow line needs a new machine

Y
You
Engineer
Now ·
Every time a line slows down, someone asks for a faster machine. In my experience, the machine is the problem about one time in five.

Why it works: A blunt view on spending gets managers and engineers talking.

04Numbers

Your scrap rate, before and after

Y
You
Engineer
Now ·
Our scrap rate on one part sat at 6.2% for a year. Everyone had accepted it. It’s 1.1% now. The fix was a fixture that cost less than one week of scrap.

Why it works: Two clear numbers and a cheap fix make a post people forward to their team.

05Behind the scenes

Where your working hours really go

Y
You
Engineer
Now ·
My job title says design engineer. My week says spreadsheet engineer. This is how my hours really split across the tools I use.

Why it works: An honest look at the real job makes other engineers laugh and reply.

06Question

The toughest site you worked on

Y
You
Engineer
Now ·
What’s the hardest site you’ve ever worked on? Mine was a substation at 3,000 metres, where the concrete wouldn’t cure and the crew needed oxygen breaks.

Why it works: Going first with a vivid answer makes people want to top it.

07Story

The survey data that turned out wrong

Y
You
Engineer
Now ·
The survey said the ground was level to within 200 mm. On day one of excavation, we hit rock 1.4 metres higher than the drawings showed.

Why it works: A gap between paper and ground is a story every civil engineer knows.

08Lesson

A safety audit finding you argued with

Y
You
Engineer
Now ·
An auditor wrote me up for a missing guard on a conveyor I had signed off. I argued for ten minutes. He was right.

Why it works: Admitting you were wrong on safety earns more respect than any win.

09Opinion

Why you still hand-calculate first

Y
You
Engineer
Now ·
I still do the first beam check by hand, on paper, before I open any software. A junior asked me why last week. This is what I told her.

Why it works: Hand calcs versus software is a debate engineers love to join.

10Numbers

The cost of one wrong unit

Y
You
Engineer
Now ·
A supplier quoted in inches. Our drawing was in millimetres. The mistake cost $8,400 and three days, and one email caused it.

Why it works: A dollar figure on a small slip makes everyone check their own emails.

11Behind the scenes

What a shift handover really sounds like

Y
You
Engineer
Now ·
Our shift handover is supposed to take ten minutes. On a good day it takes four. On a bad day it takes forty, and those are the days that matter.

Why it works: People outside plants never see handovers. People inside have strong views.

12Question

How others keep red-line markups safe

Y
You
Engineer
Now ·
Engineers, how do you stop red-line markups getting lost between site and the office? We’ve tried three ways this year. One finally stuck.

Why it works: A shared, everyday headache with a hint of your answer gets practical replies.

13Story

The first thing you designed that got built

Y
You
Engineer
Now ·
The first thing I designed that went into service was a bracket. It held a sensor on a cooling tower. I drove past it every day for three years.

Why it works: A small first win is warm, real and easy for others to match.

14Lesson

What a failed pressure test taught you

Y
You
Engineer
Now ·
Our prototype failed the pressure test at 82% of rated load. The weld was fine. The problem was a note I had written on the drawing.

Why it works: A failure traced back to yourself makes readers want the full story.

15Opinion

Overdesign is not the same as safety

Y
You
Engineer
Now ·
I used to add margin everywhere. Thicker plate, bigger bolts, one size up on every motor. A senior engineer showed me why that made the system less safe, not more.

Why it works: It turns a common habit on its head, so both camps comment.

16Numbers

A year of compressed air readings

Y
You
Engineer
Now ·
I logged our plant’s compressed air use every day for a year. About 30% of it was going into leaks. We found most of them with soapy water.

Why it works: A big number and a cheap fix make the post worth saving.

17Behind the scenes

What’s in your site bag

Y
You
Engineer
Now ·
My site bag has a tape, a torch, a marker, a notebook and spare earplugs. The notebook is the one thing I’d never leave behind.

Why it works: Small, practical and personal. People reply with what’s in theirs.

18Question

How you explain your work to family

Y
You
Engineer
Now ·
My mother still tells people I “fix machines.” I design water treatment systems. How do you explain what you do to your family?

Why it works: Light, relatable and easy to answer, so it pulls in quiet readers.

Frank had run the same kiln for 22 years when I joined as a graduate engineer. He could tell the temperature was drifting from the sound of the burner.

Why it works: Giving credit to someone on the floor is rare and people love reading it.

20Lesson

A method statement people actually read

Y
You
Engineer
Now ·
I wrote a 14-page method statement for a crane lift. On the day, nobody had read past page two. So I rewrote it on one sheet.

Why it works: Everyone has written paperwork nobody read. The fix is what they stay for.

KA note from KaustubhFounder, Wiral.Social

Why these ideas work

I started CrazyEngineers in 2005, and one thing about engineers hasn’t changed since. Most of us would rather fix the problem than write about it.

So the work stays invisible. The night you got the line back up, the clash you caught before steel went up, the audit you finally passed. Nobody outside the plant gate hears about it.

That’s a waste. The people who hire you, promote you and buy from your company are on LinkedIn. Every idea here comes from real work on sites, in plants and in design offices. You already have the stories. You just haven’t written them down.

How to use them

Pick one idea that reminds you of a real day. A test that failed, a handover that went wrong, a number you tracked. If you have to make something up, skip it.

Your job is to give the one detail only you know. The reading on the gauge, the time on the clock, the thing the fitter said. That’s what makes another engineer stop scrolling.

Tip: Check what you can share before you post. Leave out client names, drawings and anything under NDA, or you’ll spend the week explaining the post to your manager.

A fresh set of ideas goes up here every Monday. Bookmark the page and keep it next to your site notes.

Questions, answered.

New ideas every Monday, at the same address.

What should an engineer post on LinkedIn?

Real work. A problem you solved, a test that failed, a number you tracked, a lesson from site. Write it the way you’d explain it to a colleague over lunch.

Can I post about my work without breaking confidentiality?

Yes. Talk about the problem and what you learned, not the client or the drawing. “A pump skid on a water project” is enough detail for a good post.

Can engineers use these ideas for free?

Yes. Every idea and opening on this page is free to use, with no sign-up. You need a free Wiral account only if you want Wiri to write the post with you.

Will Wiri write the post the way I talk?

Yes. Tell Wiri what happened in a line or two, like “bearing failed twice, we found the real cause”, and it writes three posts in your voice for you to pick from.

Your next post is one idea away.
