How It Works

How our ATS resume checker works for software engineers

Checks how your tech stack, project headers, and skills sections parse through the engines major tech employers use. See how Resume Optimizer Pro works →

How ATS parse software engineering resumes

  • Tech stack in graphic skill bars is invisible. List every language and framework as plain text.
  • Non-standard project headers like "What I've Built" go unclassified. Use Projects or Experience.
  • GitHub URLs are not followed. Every technology must appear as plain text in the resume body.
02

Formatting traps in engineering resumes

  • Skill rating bars and icon grids never reach keyword extraction. Plain text only.
  • Two-column Word table layouts collapse into a scrambled single stream.
  • PDFs from Figma or Canva often embed text as paths, making the document unreadable.

What your optimized download fixes

Tech stack as plain text, skills under a standard header, projects under recognized headings, keywords aligned to the job description.

Why It Matters

Why ATS compatibility matters for software engineers

Major tech employers use Workday and Greenhouse at scale

Google, Amazon, and Microsoft screen thousands of applications per role. A skill graphic or two-column layout drops your application before any recruiter sees it.

Exact keyword spelling determines your match score

"Node.js" and "NodeJS" may not score as the same term. Use the exact terminology from the job description, including capitalization.

GitHub links contribute zero keyword weight

ATS systems do not follow external links. Every technology you want scored must appear as plain text in the resume itself.

FAQs

Frequently asked questions

What ATS systems do major tech companies use?

Most large tech companies use Workday, Greenhouse, or Lever. All three rely on similar parsing standards. Resume Optimizer Pro checks compatibility against the same parsing engines that power all three platforms.

Should I list programming languages in a dedicated skills section or throughout my experience?

Both. List them in a clearly labeled skills section for reliable extraction, and mention specific technologies in the context of each role where you used them. This satisfies both the keyword scanner and the human reviewer who reads past the filter.

How should I format my tech stack for ATS?

Use a plain text skills section with a standard header like Skills or Technical Skills. List technologies as comma-separated text: Python, Django, PostgreSQL, AWS, Docker. Avoid tables, columns, or visual skill bars, all of which are invisible to parsers.

Does listing too many technologies hurt my ATS score?

Relevance matters more than volume. Listing every technology dilutes keyword relevance. Tailor your skills section to match the job description and place the most relevant technologies near the top.

Do ATS systems follow GitHub or portfolio links?

No. ATS systems do not follow external links. A GitHub profile with relevant projects contributes nothing to your keyword score unless those technologies are also written as plain text in your resume.

Why is my software engineer resume not getting past ATS even though I have the right experience?

The most common causes are: tech keywords in visual elements like skill bars that parsers cannot read, a two-column layout that scrambles content order, non-standard section headers that prevent content from being classified, or keyword mismatches between your resume and the job description.

Should I submit my engineering resume as PDF or DOCX?

Submit .docx whenever possible. Word documents have the highest parsing success rate. If using PDF, generate it from Word or Google Docs, not from design tools.

Does ATS check for years of experience with a technology?

Some ATS platforms infer experience duration by associating a technology with the date range of a work entry. Mentioning technologies in context within role descriptions gives the parser a better signal.

How do I make my resume ATS-friendly without making it look generic?

ATS optimization affects structure, not substance. Use a single-column layout with standard section headers. Keep rich project and achievement language in the work history. The formatting changes are invisible to a human reader but critical to parsing.

Does ATS parse certifications like AWS Certified Solutions Architect?

Yes, if they are listed under a Certifications section with the full credential name. Abbreviations like AWS CSA may not parse correctly. Write the full credential name and include the issuing organization.
