There is a stubborn myth that tech jobs are for people who would rather talk to computers than to humans. In reality, communication skills for tech jobs are among the things employers value most. Software is built by teams, for users, and paid for by people who need to understand what they are getting. Somebody has to explain, listen, write things down and handle disagreement well.
TechDNA measures this as Communication & Empathy: your ability to explain ideas clearly, understand what other people need, and adjust how you speak or write to suit your audience. It's one of eight traits in the assessment, and it can make a real difference to how far you go in any role.
This article explains what communication looks like day to day in tech, which roles rely on it most, and how to practise it.
What does communication look like in a tech job?
It's broader than presentations. On a normal day, you might:
- Write a clear message explaining why a task is taking longer than expected
- Ask a colleague a question that includes enough detail for them to help quickly
- Explain a technical issue to a manager who isn't technical
- Listen to a customer describe a problem, even when they don't use the right words
- Write documentation so the next person understands your work
- Disagree with a design decision without making it personal
Notice how much of this is written. Many tech teams, especially remote ones, communicate mostly through chat, tickets and documents. Clear writing is often more valuable than confident speaking.
Where does empathy come in?
Empathy means understanding someone else's situation and needs. In tech, that includes:
- Users: understanding why they find something confusing, rather than assuming they are wrong
- Colleagues: recognising when someone is overloaded or stuck
- Customers: staying patient when they are frustrated
- Stakeholders: understanding the business pressures behind a request
Products built with empathy tend to be easier to use. Teams that practise it tend to work better together.
Why do communication skills matter so much in tech?
A few reasons stand out:
- Misunderstanding is expensive. Building the wrong thing because a requirement was unclear wastes weeks of work.
- Remote work depends on it. If you hope to work remotely for foreign companies from Nigeria, written communication across time zones becomes central to your job.
- Interviews test it. Technical interviews often assess how clearly you explain your thinking, not just whether you reach the answer.
- Careers grow with it. Moving into senior or leadership roles usually means more communication, not less.
Which tech roles rely on communication and empathy most?
Of the nine roles TechDNA scores, Product Manager and Technical Support lean on it most, with QA and Frontend Engineers close behind:
- Product Manager. Communication is the core of the job: aligning engineers, designers, business teams and users around what to build and why.
- Technical Support. You turn customers' descriptions into technical problems, and technical answers back into plain language, often with someone frustrated on the other end.
- QA Engineer. Writing clear bug reports, and raising problems tactfully, makes testers far more effective.
- Frontend Engineer. Building interfaces means caring about how real people experience the product, and working closely with designers.
Data Analysts also need strong communication, because a finding is only valuable if decision-makers understand it. Security Engineers explain risks to non-technical leaders. Backend, DevOps / SRE and ML / AI Engineers communicate a lot within teams and during incidents, even if they speak to customers less.

How do you build communication skills for tech?
Communication improves with deliberate practice, just like coding.
1. Practise explaining one technical idea simply
Pick something you've learned, such as what an API is or how Git works, and explain it in three sentences to someone who doesn't work in tech. If they understand it, you've succeeded. If not, try again with a different example.
2. Write the way professionals write
Good workplace writing tends to be:
- Short: get to the point in the first line
- Specific: include details like error messages, steps, dates
- Structured: use bullet points for lists of items or steps
- Action-focused: make clear what you need from the reader
A useful format for asking for help: what you were trying to do, what happened, what you expected, and what you've tried.
3. Document your projects
Every project you build should have a short README explaining what it does, how to run it, and what you learned. This practises technical writing and makes your portfolio stronger. The official Git docs and GitHub both explain how README files work.
4. Practise active listening
When someone describes a problem, repeat it back in your own words before solving it: "So the issue is that the report shows last month's numbers, not this month's?" This catches misunderstandings early.
5. Learn to give and receive feedback
In tech, people review each other's code and ideas regularly. Practise focusing feedback on the work, not the person, and treat feedback on your own work as useful information rather than criticism.
6. Join a community
Answering beginners' questions in online communities such as the freeCodeCamp forum is excellent practice. You learn to explain things patiently and clearly, and you deepen your own understanding.
Your existing experience counts
If you're switching careers from banking, teaching, customer service or sales, you probably already have strong communication skills. Calming an upset customer, explaining a complicated product, or teaching a difficult idea to a class all transfer directly to tech. Don't undervalue them on your CV.
Common communication mistakes in tech
- Too much jargon. Using technical terms with non-technical people creates confusion, not respect.
- Vague updates. "Still working on it" gives people nothing to act on.
- Staying quiet when stuck. Silence often causes more problems than asking.
- Assuming tone. Short chat messages can feel cold. A brief greeting or "thanks" goes a long way.
How does communication fit with other traits?
Communication and empathy pair well with visual thinking, because diagrams often explain ideas better than words. If people skills are your strongest asset, read about technical support as a way into tech and what a product manager does.
Frequently asked questions
Do developers really need communication skills?
Yes. Developers work in teams, write documentation, review code and explain decisions. Clear communication helps you work faster and makes you easier to work with, which matters for promotions and references.
I'm shy. Can I still succeed in tech?
Absolutely. Much tech communication is written, and many quiet people are excellent written communicators. Clarity matters far more than confidence or volume.
Is English fluency a barrier?
Clear, simple English is what most teams need, not elaborate vocabulary. Short sentences and specific details communicate well. Your skills improve as you practise writing and reading technical material.
Which role suits someone with strong people skills but little technical background?
Technical Support and Product Manager are common fits, and QA can be too. Each still needs technical learning, but your communication strength gives you a real advantage.
