There is no reliable universal list of 15 ATS keywords that every software engineer should add. Start with the job description: identify its named technologies, qualifications, and recurring language, then include only the terms that accurately describe your experience. Use them in a clear skills section and in relevant experience or project bullets that show how you applied them.
How to find the keywords that matter for a software engineering role
Read the specific posting before editing your resume. Look for repeated requirements, named tools and technologies, credentials, and responsibilities. Give more attention to terms the employer emphasizes, but include a term only when you can support it with work, project, education, or certification evidence. UT Austin Career Services recommends identifying and emphasizing job-description keywords that match your background; Indeed likewise cautions against adding keywords that do not genuinely fit your qualifications.
For technical roles, check the posting’s hard-skill vocabulary—such as tools, software, and certifications—as well as relevant industry language. Concordia University’s career guidance recommends using relevant terms in sections such as skills, experience, and summary. Its advice also applies to soft skills: connect them to a concrete action or result rather than presenting an unsupported string of traits.
The categories below are prompts for reviewing a particular posting, not a ranking of the most common or most forgotten terms. Examples like Python, Java, SQL, AWS, React, Docker, and Kubernetes are illustrative; no source here establishes them as a definitive top 15.

15 keyword categories to check against the posting
- Role title: Include the employer’s exact title or a close, accurate title that reflects the work you have done.
- Programming languages: Check for languages named in the posting, such as Python or Java, and list only those you can substantiate.
- Frameworks, libraries, and runtimes: Look for the specific frameworks, libraries, or runtime environments the role requests; React is one illustrative example.
- Databases and data technologies: Note database systems and other data technologies stated as requirements or responsibilities.
- Cloud platforms and services: Check for the named cloud platform and any specific services relevant to the role; AWS is an example, not a universal requirement.
- Build, deployment, and DevOps tools: Identify the tools the employer names for building, deploying, or operating software.
- Testing, quality, and automation: Look for the testing approaches and quality or automation tools the posting actually requests.
- APIs and integrations: Check for API technologies or integration experience relevant to the product and duties.
- Architecture and distributed systems: Include architecture or distributed-systems terminology only when the posting calls for it and your experience supports it.
- Version control and collaboration: Check for named version-control or development-collaboration tools.
- Security, reliability, and performance: Look for stated requirements in these areas and reflect the ones you have worked on.
- Methods and processes: Include explicitly requested methods, such as Agile or Scrum, when they accurately describe your experience.
- Certifications and credentials: Match required or preferred credentials only if you hold them.
- Product or industry terms: Check for domain vocabulary tied to the employer’s product or industry, and use it only when it describes your relevant experience.
- Soft skills shown through evidence: If the posting emphasizes communication, collaboration, or another soft skill, demonstrate it through an action or result rather than an unsupported standalone claim.
These categories are a practical checklist, not a claim about a universal ATS scoring model. The cited career-service guidance supports tailoring to a job posting; it does not establish that every ATS interprets synonyms the same way, rewards repeated placement, uses one standard score, or rejects resumes missing a particular term.
A practical workflow for tailoring your resume
- Save the posting and mark its language. Highlight repeated requirements, named technologies, credentials, and responsibilities. Keep the posting available while editing so you can check each term in context.
- Separate relevant terms from unsupported ones. For every marked term, note whether you can substantiate it with employment, a project, education, or a credential. Leave out anything you cannot support.
- Use recognizable wording accurately. Mirror the employer’s term when it accurately describes your skill. Expand an abbreviation alongside its full term only when both are accurate and useful to a reader.
- Place terms where they make sense. Put core qualifications in a clear skills section, then use experience or project bullets to show how you used the most relevant tools and what the work accomplished. Avoid inserting a string of unrelated keywords into a bullet.
- Keep the document readable and follow upload instructions. UT Austin recommends a chronological format and warns that tables, columns, graphics, and objects can interfere with ATS reading. Employers’ requested file formats can differ, so follow the live posting or application form.
- Save a tailored copy and verify every claim. Preserve a master resume, make a job-specific version, and re-check that each listed skill and credential is accurate before applying.
This process follows guidance from UT Austin Career Services, Indeed’s ATS keyword guidance, and Concordia University’s ATS guidance.
Rank #2
Should you use an ATS keyword checker?
A comparison tool can be an optional way to spot terms in a posting that do not appear in your resume. Jobscan describes a tool that compares a resume with a job listing; that vendor description does not independently establish the tool’s performance or predict whether an employer will advance your application. Treat any suggested term as a prompt to review, not an instruction to claim a skill you do not have. If you use a tool, consider whether it accepts the target job description, points to specific terms or document-reading issues, and clearly explains cost and data-retention practices.

Tailoring helps make relevant qualifications easier to find in your application, but keyword inclusion does not guarantee an interview. A matching term should be accurate and supported by evidence; a generic list cannot replace reading the role, and the guidance cited here does not establish one behavior shared by all applicant tracking systems. Use the posting to decide what belongs on your resume, and use the rest of the document to show the work behind those terms.
