Why Tech Job Applications Need Specific English
Applying for software engineering, DevOps, or data science roles requires vocabulary that hiring managers and ATS (Applicant Tracking Systems) recognize. Generic phrases like 'hard worker' or 'good with computers' won't make your application stand out — a term meaning your CV appears better than others in the pile.
This guide covers the essential vocabulary for CVs, cover letters, and LinkedIn profiles targeting tech companies, from startups to FAANG (Facebook/Meta, Amazon, Apple, Netflix, Google).
ATS-Friendly Language
Many tech companies use Applicant Tracking Systems to filter CVs. Include exact terms from the job description — if they say 'distributed systems,' don't write 'big computer networks.'
Essential Vocabulary for Tech Job Applications
| Term | Definition | Tech Example |
|---|---|---|
| stand out | appear better than other applications | Your CV needs to stand out — quantify your impact with metrics. |
| openings / roles | available positions (avoid 'jobs' in formal writing) | We have several senior engineer openings on the platform team. |
| stack | the combination of technologies you work with | My stack includes Python, PostgreSQL, and Kubernetes. |
| fast-paced environment | workplace where things change quickly | Startups offer a fast-paced environment with rapid iteration cycles. |
| cross-functional | working across different teams (eng, product, design) | I led cross-functional initiatives between backend and data science. |
| report to | have someone as your manager | You will report to the Engineering Manager for the Payments team. |
| previous experience | work history relevant to the role | No previous experience with GraphQL required; we provide onboarding. |
| career prospects | opportunities for promotion and growth | This role offers excellent career prospects including tech lead tracks. |
| competitive compensation | salary matching or exceeding market rates | We offer competitive compensation plus equity and benefits. |
| benefits package | extras beyond salary (health, equity, PTO) | Our benefits package includes unlimited PTO and learning stipends. |
Scenario 1: Writing a Cover Letter for a Senior Engineer Role
When applying for a senior software engineer position, your cover letter should highlight technical depth, leadership qualities, and measurable impact. Avoid vague claims — instead, describe specific projects you have carried out and the results you achieved.
- Open with: 'I am writing to apply for the position of Senior Software Engineer on the Infrastructure team.'
- Mention your stack: 'My background includes five years building distributed systems in Go and Python.'
- Show leadership: 'In my previous role as Tech Lead, I led a team of four engineers delivering a real-time data pipeline.'
- Quantify impact: 'This reduced processing latency by 40% and saved $200K annually in compute costs.'
- Close professionally: 'I look forward to discussing how my experience aligns with your team's goals.'
| Weak (Too Vague) | Strong (Specific & Quantified) |
|---|---|
| I have a lot of experience with backend systems. | I have five years of experience designing backend services handling 10M+ daily requests. |
| I am a team player who works well with others. | I collaborate cross-functionally with product and design to scope and deliver features. |
| I am passionate about coding. | I have a genuine passion for building scalable, maintainable systems. |
| I did some projects at my last job. | I led the migration from monolith to microservices, reducing deployment time by 60%. |
Scenario 2: Tailoring Your CV for a FAANG-Style Application
FAANG companies expect CVs that demonstrate system-level thinking and quantifiable achievements. Use action verbs and the XYZ formula: 'Accomplished X by doing Y, resulting in Z.'
Your CV should be relevant to the specific role — don't send the same generic document to every company. Review the job description and mirror its language.
| Section | What to Include | Example Phrase |
|---|---|---|
| Summary | 2-3 sentences: role, years, specialty | Senior Backend Engineer with 6 years building high-throughput payment systems. |
| Experience | Role, company, dates, 3-5 bullet points with metrics | Designed and shipped a caching layer that reduced API latency by 35%. |
| Skills | Your stack, organized by category | Languages: Python, Go, TypeScript. Infrastructure: AWS, Kubernetes, Terraform. |
| Education | Degree, institution, graduation year (keep brief) | B.S. Computer Science, University of Toronto, 2018. |
| Projects (optional) | Side projects or open-source contributions | Contributor to Apache Kafka; authored RFC for partition rebalancing. |
Hands-on vs. Managerial Experience
Tech CVs distinguish between 'hands-on experience' (directly writing code, designing systems) and 'managerial experience' (leading people, setting roadmaps). Senior IC roles want hands-on depth; EM roles want leadership examples.
Scenario 3: Describing Your Stack and Impact in a Job Ad Response
When responding to a job posting, match your stack to the requirements and describe your impact using concrete metrics. Hiring managers scan for keywords, so be explicit about technologies and outcomes.
- Match the stack: 'Your posting mentions Kubernetes and AWS — I have three years of production experience with both, including designing multi-region failover.'
- Describe customer-facing impact: 'I built a customer-facing dashboard that improved user retention by 15%.'
- Show ownership: 'I owned the end-to-end delivery of our authentication service, from RFC to production rollout.'
- Mention scale: 'The system I designed handles 50K requests per second at peak.'
| Informal (Slack to Recruiter) | Formal (Cover Letter / Email) |
|---|---|
| Hey! Saw the SRE role — looks cool. I've done a ton of K8s stuff. | I am writing to express my interest in the Site Reliability Engineer position. My background includes extensive experience with Kubernetes in production environments. |
| I basically rebuilt our whole deploy pipeline last year. | In my previous role, I redesigned our CI/CD pipeline, reducing deployment time from 45 minutes to under 10. |
| Happy to chat whenever! | I would welcome the opportunity to discuss how my experience aligns with your team's needs. |
Formal vs. Informal Register in Applications
Tech culture is often casual, but job applications still require formal register. Save informal language for post-offer Slack conversations — your cover letter and CV should be professional.
| Context | Opening | Closing |
|---|---|---|
| Formal letter (unknown recipient) | Dear Sir or Madam / Dear Hiring Manager | Yours faithfully / Sincerely |
| Formal letter (known name) | Dear Ms. Chen / Dear Hiring Team | Yours sincerely / Best regards |
| Email to recruiter (first contact) | Hello [Name] / Hi [Name] | Best regards / Thanks |
| Slack (after offer) | Hey! / Hi team 👋 | Thanks! / Cheers |
Cultural Note: US vs. UK Conventions
In American English, 'Sincerely' is standard for formal closings. In British English, use 'Yours faithfully' when you don't know the recipient's name, and 'Yours sincerely' when you do. Tech companies often accept either, but consistency matters.
