English for Software Engineers: The Practical Guide

Type "english for software engineers" into Google and you'll get vocabulary lists, grammar guides, and "5 phrases to use in your next meeting" content. All of it treats technical English as a vocabulary problem, but what actually breaks down is communication.

If you can read technical documentation in English but freeze in a stand-up, this guide is for you. If you write clean code but your PR comments come out formal and stiff, this guide is for you. If you passed a B2 test and your first all-English sprint retrospective still felt like a different language, this guide is especially for you.

English for software engineers is a set of communication situations, each with its own rhythm, expectations, and failure modes. Vocabulary lists won't prepare you for a code review where a senior engineer types fast and expects you to respond in thread. Grammar tips won't help you push back on an architectural decision in a fast-moving meeting where everyone else is a native speaker.

"English for software engineers" is four different communication skills wearing the same badge. Before you choose a practice approach, be honest about which gap is holding you back.

Take Diego, a senior backend engineer in Buenos Aires who joined a Berlin-based fintech a year ago. He codes in English daily, reviews PRs in English, and listens to English tech podcasts on his commute. But in the Tuesday architecture meeting where senior engineers debate decisions at speed, he listens, nods, and never pushes back, even when he disagrees and has the strongest opinion in the room on the system he built. What fails him is using English in real time, under pressure.

The 4 communication contexts that matter

Async reading and writing covers Slack threads, GitHub comments, PR reviews, Jira tickets, RFCs and documentation. Text-based, asynchronous, and forgiving, because you have time to compose, edit and look things up. Most engineers have some foundation here.

Spoken meetings are stand-ups, sprint planning, retrospectives, 1-on-1s with your manager, all-hands calls. Real-time, verbal, high social stakes. This is where most non-native engineers hit a wall, because there's no time to translate before speaking.

Technical discussions sit in between: pair programming, architecture reviews, debugging sessions, code walkthroughs. Partly written, partly verbal, highly contextual. They assume shared technical vocabulary but use it fast and informally, in a register no textbook covers.

High-stakes English is job interviews, performance reviews, stakeholder presentations, client calls. Lower frequency, higher consequences. Most engineers over-prepare vocabulary and under-prepare the thinking-while-talking part, which is where interviews and presentations actually get decided.

A 3-question diagnostic

Answer these honestly:

If that's your profile, what closes the gap is real-time speaking practice in technical situations, with someone who gives you honest, immediate feedback.

Here are the six serious approaches engineers use, what each is good at, and where each falls short for technical communication specifically.

1. General English apps

Duolingo, Babbel and their equivalents are where many engineers start. Mobile, gamified, built for the general learner, and good at exactly that: building a daily habit, drilling basic vocabulary, patching foundational grammar gaps.

They don't know you're a software engineer. They'll drill you on food vocabulary and comparative adjectives while you're trying to learn how to push back on a feature scope in sprint planning. Their speaking practice is built for everyday conversation, not for the technical situations you actually work in, like a code review or a live architecture call.

General English apps are better when you want a daily habit and foundational drilling at your own pace; a tech-specific approach is better when you need to perform in real engineering situations. Keep the app if you have a streak going. Don't mistake it for technical communication practice.

2. English tech media (podcasts, YouTube, conference talks)

Most engineers already consume hours of English-language tech content, and it's valuable: passive exposure to technical vocabulary, native-speaker cadence, and industry-specific language. Comprehension gets faster over time.

Comprehension and speaking are different skills, though. You can follow a 45-minute conference talk on distributed systems and still be unable to explain your own PR in a live review. Listening is input; speaking is output, and the gap between them is where most engineers get stuck.

3. Immersion at work

Engineers already in English-heavy environments (all-English Slack, international teams, remote-first companies) get constant low-stakes exposure to how real technical communication sounds, plus contextual vocabulary that actually sticks.

Immersion without structure is slow and full of blind spots. You'll naturally avoid the situations where you're weakest, and nobody at sprint planning will correct you, because they're focused on shipping. The gaps that embarrass you don't get fixed unless you practice them deliberately.

Immersion gets you background improvement. Deliberate practice is a separate thing you have to add.

4. Writing practice (GitHub, Slack, documentation)

Deliberately writing more technical English (detailed commit messages, thoughtful PR comments, clear documentation) is a high-return habit. It improves clarity, register and professional tone, and reviewing other people's writing forces you to think explicitly about what works.

Speaking asks for something writing never tests. A developer who writes excellent documentation can still be the quietest person in the retrospective. Async written English and real-time spoken English don't substitute for each other.

Do this anyway, especially for GitHub and Slack. Just don't expect it to close your spoken gap.

5. AI conversation tools

ChatGPT's voice mode for speaking practice, Grammarly for writing feedback, DeepL for checking a phrase you're unsure of: these give you low-pressure reps without a human watching, and they're a useful first step for engineers too anxious to start with a real person.

But AI can't read the social texture of a technical conversation: the hesitation before your status update, the moment when you're about to say "I'm not sure this approach is right" and then don't. Your nervous system also knows the session isn't a real engineering discussion, so the confidence you build doesn't transfer cleanly to the stand-up.

Use AI for the first reps, humans for the real ones.

6. 1-on-1 practice with a technical English tutor

A real person, on video, focused entirely on the English situations your work requires. A skilled tutor can run mock stand-ups, practice code review discussions, rehearse architecture explanations, and give you immediate feedback on register, clarity and confidence. Unlike a colleague, their job in that session is to help you get better rather than ship a feature. Unlike AI, they can read the full social texture of a conversation and tell you when something would land badly with a senior engineer or a non-technical stakeholder.

Cambly's tutors come from countries including the US, UK, Canada, and Australia, and they're available 24/7 across time zones, which matters when your free hour is 11 p.m. in São Paulo or 6 a.m. in Tokyo.

Progress stalls if you don't push the scenarios. If every session rehearses "describe your current project," you'll get very good at describing your current project. Push into the uncomfortable ones: disagreeing with a technical decision, explaining why a deadline is unrealistic, asking for a promotion in English.

The impact column is our assessment of how much each approach moves real-time spoken English when it's used as the primary method. Most engineers get further by combining methods, especially writing practice alongside regular tutor sessions.

Not all software engineers have the same gap. Here's which of Cambly's technical English guides fits your profile.

If your biggest gap is spoken meetings and stand-ups, common for B1–B2 engineers who feel stuck, prioritize real-time speaking practice in technical scenarios. Two 30-minute sessions a week focused specifically on stand-ups will do more for that gap than app practice.

If your gap is high-stakes situations (technical interviews, performance reviews, client presentations) you need scenario prep. Technical interviews have their own question types, pressure patterns and answer structures. See our guide to English for job interviews for how to prepare each of them.

If your gap is async written English (PR comments, documentation, RFCs) writing practice and deliberate documentation habits will serve you better than speaking drills.

For the broader picture of building spoken fluency across all professional contexts, see our guide to English speaking practice.

This is the plan for an engineer at B1–B2 level whose main gap is spoken meetings.

Week 1. Diagnose. Record yourself giving a 2-minute status update on your current work. Listen to it. Notice which sentences you avoided because you weren't sure how to phrase them. That list is your actual curriculum.

In parallel, write one PR comment or Slack message a day in English that you'd otherwise have written in your native language..

Week 2. First real-time reps. Book a technical English session and tell the tutor your gap directly: "I struggle with stand-ups and real-time technical discussions." Share the status update you recorded, practice it live, then practice the uncomfortable version, where someone asks a follow-up you didn't prepare for.

Week 3. Push into uncomfortable territory. Practice the situations you most avoid: disagreeing with a technical decision, asking for clarification without losing face, explaining why an estimate needs to change. These stay exactly as hard for as long as you avoid them.

Week 4. Apply and iterate. Use what you've practiced in real meetings. Notice where you still translate mentally before speaking, and bring those specific moments to your next session.

If you've read this far, you already know which gap is yours.

Pick one scenario you've been avoiding: the stand-up where you always say less than you mean, the code review where you nod instead of pushing back, the meeting where you have an opinion and keep it to yourself. Start there. Give it one 30-minute session, focused on that scenario alone.
