Look closely at the specialization: cloud, network and application security engineers often use different tools and have different expectations.

Security engineers make computer systems safer by building, testing and improving security measures. Their work can involve networks, cloud accounts, software or tools that help a security team find problems.

Many positions require experience with IT systems or programming before moving into engineering.

What does a security engineer do?

An engineer might configure a firewall, remove unnecessary access to a cloud account, correct a security setting or write a script that checks systems for mistakes. They work with IT staff, developers and security analysts to test changes and fix problems without interrupting normal operations.

The duties depend on the job’s focus:

O*NET’s Information Security Engineers profile lists related tasks. A security analyst often spends more time examining alerts; an engineer more often builds or improves the protection tools. The jobs can overlap.

How to become a security engineer

Learn the basics. Understand networks, Windows or Linux, cloud services, accounts and permissions. These explain what you are trying to protect.

Gain technical experience. IT support, systems administration, software development, cloud operations and security analysis can all provide useful preparation. Some employers prefer a bachelor’s degree in computer science, IT or cybersecurity; others accept equivalent experience. See the cybersecurity bachelor’s guide.

Practice on your own systems. Build a small lab, set access permissions, configure a firewall or write a simple script. Explain what you changed and how you tested it. Only work on systems you own or have permission to test.

Choose jobs that match your skills. Junior roles exist, but many employers want prior experience. For example, Hex’s Cloud Security Engineer posting asks for five or more years of cloud security engineering experience. That is one experienced role, not a universal requirement.

Skills and certifications

Useful skills include networking, operating systems, cloud access controls, troubleshooting, identifying vulnerabilities and scripting with tools such as Python or PowerShell. Clear communication matters because engineers must explain changes to other teams.

• CompTIA Security+ helps establish basic cybersecurity knowledge. It is not proof of advanced engineering skills. Read the Security+ guide.
• AWS Certified Security – Specialty focuses on securing AWS services and is aimed at experienced cloud professionals. See AWS’s certification information.
• CISSP is generally more appropriate later in a career. Full certification normally requires five years of qualifying experience in at least two domains, with limited credits permitted. Review ISC2’s requirements.

Choose credentials that relate to the kinds of jobs you want, not simply the longest list of certifications.

Security engineer salary in the United States

There is no official salary number that covers every security engineer title. These sources measure different groups:

These are not entry-level guarantees. Pay changes with experience, location, employer, and specialty. Do not combine the figures into a new average.

Job outlook

BLS does not publish a forecast just for jobs titled security engineer. For the broader information security analyst occupation, BLS reports a $129,180 median wage in May 2025 and projects 21% employment growth from 2025 to 2035. These are broader-occupation statistics, not direct measures of security engineer pay or growth.
