Tech recruiters scan engineer resumes for three things: technology stack match, evidence of impact, and scale of experience. Unlike other roles, they do not spend much time on professional summaries or buzzwords — they want to see actual technical skills and what you have built.

What Tech Recruiters Look For

Tech recruiters scan engineer resumes for three things: technology stack match, evidence of impact, and scale of experience. Unlike other roles, they do not spend much time on professional summaries or buzzwords — they want to see actual technical skills and what you have built.

Tech stack alignment — Match the job posting: React, Python, AWS, Kubernetes, etc.

Evidence of impact — Did your work matter? Did users benefit? Did performance improve?

Scale — How many users? Requests per second? How complex was the system?

GitHub or portfolio — Optional but valuable — shows code quality and contributions.

Resume Format and Length

Under 5 years experience

One page is acceptable and often preferred. Be ruthless about what gets included. Focus on projects with impact, relevant skills, and education.

Senior engineers (5+ years)

Two pages is standard. Include senior-level accomplishments, architectural contributions, team leadership, and major projects. ATS handles longer resumes well in tech.

Use a single-column, ATS-friendly layout. No graphics, no skills bars (they are useless and waste space), no colourful charts. Tech is text-based — keep it simple and scannable. See our resume format guide for more detail.

Section Structure

Recommended order:

  1. Contact information (name, location, phone, email, GitHub)
  2. Professional summary (optional — only if it adds value)
  3. Technical skills (by category)
  4. Professional experience
  5. Projects (optional — especially for junior engineers or career changers)
  6. Education
  7. Open source / GitHub contributions (optional)

Technical skills are prioritised early — this is what tech recruiters scan for first.

Professional Summary Examples — By Level

Junior Software Engineer (0–2 years)

Mid-Level Software Engineer (3–5 years)

Full-stack engineer with 4 years of experience building and scaling web applications serving 500K+ users. Expertise in React, Python, AWS, and microservices architecture. Track record of delivering features on time and reducing API latency by 40%.

Career Changer into Engineering

Recently completed [bootcamp/program] with focus on full-stack development. Strong problem-solving skills from previous career in [field] combined with solid technical foundation in JavaScript, React, and databases. 3 projects deployed to production. GitHub: [link]

Technical Skills Section

Do not use a skills bar, rating system, or pie chart. Tech recruiters ignore these — they are subjective and waste space. List your technical skills section in categories as plain text. This is easier to scan and ATS-friendly.

TECHNICAL SKILLS

Languages: JavaScript, Python, Java, SQL, HTML/CSS

Frontend: React, Vue.js, Next.js, Tailwind CSS, Redux

Backend: Node.js, Express, Django, Flask, Spring Boot

Databases: PostgreSQL, MongoDB, Redis, DynamoDB

Cloud & DevOps: AWS (EC2, S3, Lambda), Kubernetes, Docker, CI/CD (GitHub Actions, Jenkins)

Tools & Platforms: Git, Linux, REST APIs, GraphQL, Webpack, npm

Soft Skills: Technical mentoring, system design, code review, agile/scrum

  • List technologies that appear in the job posting first
  • Group by specialisation (frontend, backend, DevOps) or by depth of experience
  • Do not list every language you have ever touched — only ones you use regularly or recently
  • Include soft skills that matter for engineering leadership roles (mentoring, system design, code review)

How to Write Impactful Bullet Points

The difference between a weak and strong engineering resume is specificity and metrics. Use technical action verbs and quantify your impact.

Weak

  • "Worked on backend services using Python and Docker"
  • "Improved database queries"
  • "Collaborated with team members"

Strong

  • "Built microservices in Python handling 100K req/s; optimised queries reducing query time from 2s to 200ms (10x improvement)"
  • "Led migration of monolithic Node.js app to microservices on Kubernetes, reducing deploy time from 30 to 5 minutes"
  • "Implemented CI/CD pipeline reducing deployment time from 2 hours to 15 minutes; cut production incidents by 60%"

Bullet structure

[Action] + [Technology] + [Outcome/Metric]

  • "Built [X] using [tech] that [impact/metric]"
  • "Optimised [system] by [change] resulting in [quantified improvement]"
  • "Reduced [metric] from [before] to [after] by [approach]"

Projects Section — When and How to Include

Include if:

  • You are a junior engineer with limited professional experience
  • You have significant open-source contributions
  • Projects showcase skills relevant to your target role

Exclude if:

  • You have 3+ years of professional experience
  • Projects are outdated or use unrelated technologies
  • You need the space for professional accomplishments

GitHub and Portfolio Links

Always include a link to your GitHub profile at the top of your resume next to your email. Recruiters will check it.

Do include:

  • Recent projects with clean code and good documentation
  • Open-source contributions
  • Diverse projects showing range (frontend and backend, different languages)
  • README files explaining what each project does

Do not include:

  • Very old projects (10+ years old, especially outdated technologies)
  • Incomplete or messy projects
  • Private repositories (not visible to recruiters)

Common Software Engineer Resume Mistakes

Mistake 1: Skills bars or rating systems

"Expert: React ⭐⭐⭐⭐⭐" is useless. Tech recruiters ignore these. Use text category lists instead.

Mistake 2: Listing every technology ever touched

Do not list "I once used PHP in 2010." List technologies you have used in the last 1-2 years or that are relevant to your target role.

Mistake 3: Not quantifying impact

"Improved performance" tells us nothing. "Reduced API latency from 800ms to 200ms (4x improvement)" is concrete and memorable.

Mistake 4: Responsibilities instead of accomplishments

"Responsible for building user authentication" is weak. "Built JWT auth used by 100K+ users; reduced login time from 3s to 500ms" shows impact.

Mistake 5: No GitHub or portfolio link

For engineers, GitHub is your portfolio. Include it at the top of your resume, even if your public repos are small.

Mistake 6: Overstating expertise

If you used Python for 3 months in one project, do not list it as a core skill. Interviewers will ask follow-up questions.

Mistake 7: Old resume format or two-column design

Do not use graphic-heavy two-column layouts. Tech recruiters scan text. Simple, ATS-friendly, single-column format is best.

Frequently Asked Questions

Should I include years of experience with each technology?

No — it is a waste of space and often inaccurate. Focus on what you use or have used recently. If a technology is important, it will be obvious from your job descriptions.

What if I have open-source contributions but no released projects?

That is fine. Include your open-source contributions in your resume. Link to the projects you contributed to and highlight the impact — bug fixes, features, performance improvements.

Should I include side projects if I am a senior engineer?

Only if they are impressive or demonstrate skills not shown in your professional work. If you have strong professional accomplishments, focus on those instead.

How do I explain employment gaps in tech?

Be brief and honest — career break, learning new skills, relocation, health reasons. Most tech companies understand reasonable gaps. Focus on what you have been doing to stay current.

Should I list all my programming languages or only major ones?

List languages you have used in the last 1-2 years or that are relevant to your target role. If you know 10 languages, list the 5-6 most relevant. Quality over quantity.

Is a cover letter necessary for software engineer roles?

Most tech companies screen primarily on resume and coding challenges. A cover letter is rarely required, but if submitted, keep it brief and specific to the company and role.

How important is my GPA or degree type for senior engineer roles?

After 3+ years of experience, your work history matters far more than your degree. Remove GPA from your resume once you have professional experience. Focus on accomplishments and impact.
