🎯 What Is the Goal of Your Resume?

The primary goal of your resume is to get you interviews —not to list everything you've ever done.

1. For junior engineers, your resume should show:

• Your potential to grow in a technical environment.
• Foundational technical skills.
• Passion for learning, through projects, hackathons, coding competitions or coursework.

2. For senior engineers, your resume should highlight:

• Proven track record of impact
• Leadership, ownership, and ability to scale systems or teams
• Experience driving technical direction or delivering complex solutions

In both cases, your resume should tell a clear, tailored story about why you're a strong fit for the role—focusing on outcomes, not just responsibilities.

🏆 Structure: relevant things first

The recruiter or hiring manager will read your resume top to bottom. You’ll want the most relevant parts to be at the top and less relevant ones towards the bottom. When you have lots of experience, it’s fine to go beyond just one page: just make sure that everything relevant is still on the first page.

When you’re a new grad or bootcamp grad:

• Real-world experience, if you have any, including internships.
• Contribution to real-world projects: e.g., open-source projects.
• Details about your education.
• Projects that stand out for a reason or another. Things that go beyond “Hello, world."
• Tutoring and leadership positions in student groups.

When you have work experience:

• Work experience: current company and title.
• Languages and technologies that you are proficient with.
• Education details: these become less relevant over time. With a few years’ experience, they can still be good indicators. After multiple jobs or decades, consider moving this lower down.
• Extracurricular things like patents, publications, talks, and standout open source contributions.
• Certifications. This one is interesting. Companies hiring for generalists don’t usually care, especially if it’s not an industry-wide recognized certification. Agencies and more “traditional” companies could give it some weight, though.
• Personal projects. The more experience you have, the less important these become. Standout contributions, especially to popular projects, could be an exception. Still, they rarely weigh more than your work experience.
• Interests: these can be a starting point for the conversation on an onsite interview, and they make your resume more personal.

It can feel painful to cut away some of your experience from your resume. But keep in mind your goal: it’s to have that recruiter call.

📙 Action Verbs for a Software Engineer Resume

Use strong, specific action verbs to start each bullet point on your resume. These verbs convey clarity, impact, and initiative—essential for both junior and senior engineers.

Tip: Begin each resume bullet point with one of these verbs, followed by what you did and what the result was.

Example: • Refactored legacy backend code in Python, reducing API response time by 50%.

⭐ Using the STAR Method to Write Strong Resume Bullet Points

A powerful way to write impactful bullet points in your resume is by using the STAR method:

Situation → Task → Action → Result

It helps you highlight not just what you did, but also why it mattered—making your achievements more compelling to hiring managers.

What Each Part Means

• Situation – Brief context about where/why something needed to be done
• Task – What goal or problem you were responsible for
• Action – The specific steps you took
• Result – The outcome or measurable impact of your action

Example (Bad vs. STAR-Enhanced)

❌ Weak Bullet:

Worked on backend APIs using Node.js.

✅ STAR-Based Bullet:

Designed and implemented RESTful APIs in Node.js to support a new feature rollout, reducing data sync latency by 40% and improving user experience.

Tips for Applying STAR in Your Resume

• Start with an action verb (e.g., built, led, designed, improved)
• Quantify results wherever possible (e.g., “increased performance by 25%”)
• Keep it concise—you don’t need to explain every detail, just the essence of the impact
• Focus on what changed because of your work, not just what you did

STAR in a Software Engineer’s Context

Before:

Contributed to a React frontend for internal dashboards.

After (STAR):

Developed reusable React components for internal dashboards, reducing frontend bugs by 30% and increasing development speed across teams.

Using STAR turns vague contributions into clear, outcome-driven achievements—making your resume stronger and more persuasive to both recruiters and hiring managers.

📺 How to Set Up an ATS-Friendly Software Engineer Resume

Most companies—especially mid to large-sized ones—use Applicant Tracking Systems (ATS) to screen resumes before a human sees them. An ATS parses your resume to find keywords and evaluate fit. If your resume isn't formatted properly, it might get filtered out before a recruiter ever reads it.

Here’s how to ensure your resume is ATS-friendly:

1. Use a Clean, Standard Format

• Use a simple, single-column layout
• Stick to common fonts: Arial, Calibri, Helvetica, Times New Roman
• Avoid tables, columns, text boxes, images, or graphics
• Save and submit your resume as a PDF, unless instructed otherwise

2. Use Clear Section Headings

Stick to conventional headings like:

• Summary
• Skills
• Work Experience
• Education
• Projects
• Certifications (optional)

These help ATS systems parse and categorize your resume correctly.

3. Include Keywords from the Job Description

• Mirror the exact terminology used in the job listing (e.g., “JavaScript,” not “JS”)
• Include both acronyms and full phrases when relevant (e.g., “OOP (Object-Oriented Programming)”)
• Incorporate skills, tools, and technologies in the Skills and Experience sections naturally

4. Stick to Text, Not Graphics

• Avoid logos, charts, and design-heavy templates
• Do not put your contact information inside a header or footer (ATS might skip it)
• Don’t use custom icons or images for skills—write them out plainly

5. Use Simple Bullet Points

Each job or project should include:

• What you did
• What tools/technologies you used
• What impact you made

Example:

• Built a RESTful API using Node.js and Express, reducing response time by 40%

6. Test Your Resume

Before submitting:

• Copy-paste your resume into a plain text editor. If it’s unreadable, the ATS may struggle too
• Upload it to free ATS testing tools like Jobscan or ResumeWorded
• Use an online resume validator to check formatting and keyword usage

7. Common Mistakes That Break ATS Parsing

• Putting your name in a header or footer
• Using multiple columns or resume builders with hidden formatting
• Using uncommon fonts or overly styled designs
• Leaving out keywords that appear in the job description

Think of your resume as code for the ATS to parse. If it can’t “compile,” it won’t run—no matter how good the logic is. Keep it clean, structured, and keyword-rich.
