Resume Optimization

Comprehensive guidance for creating effective software engineering resumes that pass ATS systems and resonate with hiring managers.

When to Use This Skill

• Reviewing or improving a software engineer's resume
• Crafting impactful achievement bullets from work experience
• Optimizing resume content for ATS keyword matching
• Tailoring a resume for a specific job description
• Understanding modern resume structure and formatting

Core Principles

The Resume's Purpose

A resume is a marketing document, not a job history. Its purpose is to:

1. Pass ATS screening (keyword matching)
2. Capture a recruiter's attention (6-second scan)
3. Demonstrate value through quantified achievements
4. Secure an interview opportunity

What Makes Engineering Resumes Different

Software engineering resumes should emphasize:

• Technical impact: Specific technologies, scale, and performance improvements
• Business outcomes: Revenue, cost savings, user growth, time savings
• Leadership signals: Mentoring, cross-team collaboration, technical decisions
• Quantification: Numbers that demonstrate scope and impact

Resume Structure Quick Reference

Recommended Section Order

1. Contact Information - Name, email, phone, LinkedIn, GitHub (optional)
2. Professional Summary (optional) - 2-3 sentences for senior roles
3. Skills - Technical skills organized by category
4. Experience - Reverse chronological, 3-5 most relevant roles
5. Projects (optional) - For junior engineers or career changers
6. Education - Degrees, certifications, relevant coursework

Length Guidelines

Formatting Essentials

• Font: Clean, readable (Calibri, Arial, Garamond - 10-12pt)
• Margins: 0.5-1 inch
• Format: PDF (preserves formatting)
• File naming: FirstName_LastName_Resume.pdf

Achievement Bullet Formula

Action Verb + Specific Task + Quantifiable Result

[Strong Action Verb] [specific task/project] using [tools/methods], resulting in [quantified outcome].

Strong Action Verbs by Category

Quantification Types

• Time: "Reduced deploy time from 2 hours to 15 minutes"
• Money: "Saved $50K/year in infrastructure costs"
• Scale: "Scaled system to handle 1M daily requests"
• Improvement: "Improved test coverage from 40% to 85%"
• Frequency: "Reduced support tickets by 70%"

ATS Optimization

What ATS Systems Look For

1. Keyword matching - Skills, tools, technologies from job description
2. Job title alignment - Titles that match or relate to the target role
3. Section structure - Standard sections that ATS can parse
4. Clean formatting - No tables, columns, graphics, or headers/footers

ATS-Friendly Practices

• Use standard section headings ("Experience", "Skills", "Education")
• Include both spelled-out terms AND acronyms ("Continuous Integration (CI)")
• Mirror exact phrases from job descriptions
• Avoid images, icons, or non-text elements
• Use bullet points (-, *, •) not custom symbols

Keyword Extraction Strategy

When tailoring for a job description:

1. Identify required skills - Listed in "Required" or "Must have" sections
2. Note preferred skills - Listed in "Nice to have" or "Preferred"
3. Capture soft skills - Leadership, communication, collaboration terms
4. Extract action verbs - What the job says you'll "do" or "lead"
5. Match technologies - Specific tools, languages, frameworks mentioned

Tailoring Strategy

The 80/20 Rule

• 80% base resume: Core experience and skills that apply broadly
• 20% customization: Targeted adjustments for each application

What to Customize

1. Professional Summary - Align with job's key requirements
2. Skills Section - Reorder to prioritize job's requirements
3. Achievement Bullets - Emphasize relevant accomplishments
4. Keywords - Incorporate exact terms from job description

Red Flags to Avoid

• Generic objective statements ("Seeking a challenging position...")
• Job duties instead of achievements ("Responsible for...")
• Unexplained gaps without context
• Typos or inconsistent formatting
• Outdated technologies prominently featured

User-Facing Interface

When invoked directly by the user, this skill tailors a resume for a specific job description.

Execution Workflow

1. Parse Arguments - Extract job description text or URL from $ARGUMENTS. If URL provided, fetch the job description content. If no arguments, ask the user for the job description.
2. Extract Keywords - Analyze the job description for required skills, preferred skills, soft skills, action verbs, and specific technologies.
3. Find Resume - Search for the user's resume in common locations (current directory, docs/, ~/.claude/temp/). If not found, ask the user for the resume location.
4. Analyze Gaps - Compare resume content against job description keywords. Identify missing keywords, weak achievement bullets, and alignment opportunities.
5. Generate Tailored Output - Produce:

- Keyword match report (matched vs missing) - Rewritten achievement bullets incorporating job keywords - Suggested skills section reordering - Professional summary tailored to the role - ATS optimization recommendations

1. Offer to Apply Changes - Ask user if they want changes applied directly to their resume file.
