Week of 26 Oct · 20 ideas · Updated every Monday

20 LinkedIn post ideas for software engineers, this week.

Ideas from the real work of building software: on-call, code reviews, estimates and legacy code. Each has an opening that works. Use them free, or let Wiri write it in your voice.

How Wiral helps software engineers
02Question

Ask about the oldest code they’ve changed

Y
You
Software engineer
Now ·
What’s the oldest code you’ve had to change at work? Mine was a billing script from 2011, with a comment at the top that said “do not touch”.

Why it works: Everyone has a legacy horror story. Going first makes replies easy.

03Question

Ask managers if they miss writing code

Y
You
Software engineer
Now ·
Engineers who moved into management, do you miss writing code? I’ve been offered an engineering manager role, and I have until Friday to decide.

Why it works: A real decision with a deadline. People want to help and share their own path.

04Question

Ask how much code AI writes for them

Y
You
Software engineer
Now ·
How much of your code does an AI assistant write now? I went through my last month of commits. It was more than I expected, and less than people claim.

Why it works: A topic every engineer has a view on, with your own honest count to start.

05Question

Ask about holiday code freezes

Y
You
Software engineer
Now ·
Does your team still do a code freeze before the holidays? Ours starts December 15. Every year, someone asks for an exception on December 14.

Why it works: A shared, slightly funny ritual. People reply with how their team handles it.

06Question

Ask what a great manager did for them

Y
You
Software engineer
Now ·
What’s one thing a great engineering manager did for you? Mine blocked a whole quarter of meetings so our team could finish a migration.

Why it works: A warm question that gets thoughtful replies, and managers read them closely.

07Story

The bug that only happened on Tuesdays

Y
You
Software engineer
Now ·
We had a bug that only showed up on Tuesdays. It took three engineers and two weeks to find. The cause was a cron job someone set up in 2019.

Why it works: A mystery with a weird detail. Engineers can’t scroll past an odd bug.

08Story

The Friday deploy you rolled back

Y
You
Software engineer
Now ·
I deployed at 4:45 PM on a Friday. I know. By 5:10 the error rate was 9%, and I learned more in the next hour than in the month before.

Why it works: A rule everyone knows, broken, with a clock and a number. It reads like a confession.

09Story

Your first days in a new codebase

Y
You
Software engineer
Now ·
On my first day, the onboarding doc said local setup would take an hour. It took me four days. I wrote down every step that was missing.

Why it works: Every engineer has fought a setup guide. What you did next makes people read on.

10Story

The interview question you froze on

Y
You
Software engineer
Now ·
In a final-round interview, I froze on a question about rate limiting. I got the offer anyway. Months later, the interviewer told me what made the difference.

Why it works: Job seekers read every word, and the reveal isn’t what they expect.

11Story

Deleting code nobody had called in a year

Y
You
Software engineer
Now ·
Last week I deleted 2,300 lines I wrote two years ago. I was proud of them once. Nobody had called that code in 14 months.

Why it works: Letting go of your own work is honest and oddly satisfying to read about.

12Lesson

The missed edge case that made you test

Y
You
Software engineer
Now ·
I didn’t write tests for the first three years of my career. Then one missed edge case charged 140 customers twice. That week changed how I work.

Why it works: A real cost behind a habit people argue about. The number does the convincing.

13Lesson

An estimate that was off by weeks

Y
You
Software engineer
Now ·
I told my manager the feature would take three days. It took three weeks. Now I ask four questions before I give anyone an estimate.

Why it works: Every engineer has blown an estimate. Four questions is something they can use tomorrow.

14Lesson

Reading pull requests from other teams

Y
You
Software engineer
Now ·
The fastest I ever improved as an engineer wasn’t from writing code. It was the six months I spent reading every pull request on a team I wasn’t on.

Why it works: A surprising way to grow that anyone can start this week.

15Lesson

The README nobody asked you to write

Y
You
Software engineer
Now ·
I wrote a two-page README for a service nobody wanted to touch. Three months later it was the most linked doc in our team channel.

Why it works: Unglamorous work with a visible payoff. It nudges people to do the same.

16Lesson

Not rewriting a junior engineer’s work

Y
You
Software engineer
Now ·
The junior engineer I mentor shipped her first feature last week. I almost rewrote part of it before release. I’m glad I didn’t.

Why it works: Senior engineers feel this pull. Holding back is the lesson they want to hear about.

17Opinion

Clever code is a cost, not a skill

Y
You
Software engineer
Now ·
I once squeezed a 40-line function into four lines and felt brilliant. The next engineer to touch it spent a full afternoon working out what it did.

Why it works: A view most engineers share but rarely say, told through one specific function.

18Opinion

Six engineers don’t need 23 services

Y
You
Software engineer
Now ·
Our team of six ran 23 microservices. We spent more time on deploy pipelines than on features. Last year we merged them into three.

Why it works: It goes against a popular architecture with numbers from your own team.

19Opinion

Why your team dropped story points

Y
You
Software engineer
Now ·
My team stopped using story points in April. We argued less, planned faster, and our delivery dates got more accurate, not less.

Why it works: Story points split every team. A result from dropping them starts a debate.

20Opinion

Write the design doc before the meeting

Y
You
Software engineer
Now ·
Most engineering design meetings should start as a written doc. Last quarter we tried it for every decision. Meetings got shorter, and the decisions stuck.

Why it works: A clear position plus a real trial. Easy to agree with, easy to argue with.

KA note from KaustubhFounder, Wiral.Social

Why these ideas work

Most software engineers think LinkedIn isn’t for them. It’s for recruiters and people announcing new jobs.

Meanwhile you fix a bug that took a week to find, survive an on-call night, or ship a migration nobody thought would finish. Then you tell nobody outside your team. That work is invisible to the next hiring manager, the next team lead, the next person who could open a door for you.

Every idea here comes from real engineering work: code reviews, estimates, flaky tests, legacy code. You don’t need to be an influencer. You need to explain one thing you learned, the way you’d explain it to a teammate.

How to use them

Pick something from your last sprint or your last incident. If you had to explain it in standup, you can write it as a post.

Keep it plain. One problem, what you tried, the number that changed. Skip the jargon your recruiter friends won’t follow, and never share anything your company would treat as private.

Tip: Don’t wait until you’re job hunting to start. Engineers who only post when they need a job look exactly like that.

What should a software engineer post on LinkedIn?

Post what you learned from real work. A bug you chased, a review that changed your mind, a number that improved. Keep it plain so recruiters and non-engineers can follow it too.

Can posting on LinkedIn help a software engineer get hired?

Yes. Hiring managers read posts before interviews. A few clear posts about how you solve problems tell them more than a list of languages on your profile.

Are these post ideas for engineers free?

Yes. Use any idea on this page, any week, with no sign-up. You only need a free account if you want Wiri to write the post in your voice.

Will Wiri write a post from my bug or project?

Yes. Pick an idea, tell Wiri what happened in a line or two, and you get three posts in your voice to choose from. Nothing is posted until you choose.

Your next post is one idea away.
