IT Job Watch: Application security engineer – Spiceworks

You’ll soon discover two key facts if you start researching application security engineer roles. First, it’s one of the most critical positions in cybersecurity today. Second, this role could see major demand shifts as artificial intelligence becomes more common.

Quite simply, this job appears to be a victim of contradictions – AI capabilities make the role ever more important, while at the same time, AI is increasingly being trained to do many of its responsibilities.

“Cybersecurity remains one of the more resilient areas of technology hiring as AI creates a cybersecurity paradox,” explains Kanani Breckenridge, CEO and ‘chief headhuntress’ at placement firm Kismet SearchOpens a new window . “AI-assisted development helps companies produce software faster, but the resulting code still needs security validation. More code, more integrations, and faster deployment cycles create a greater need for sophisticated application security practices as this keeps expanding.”

To get a better sense of demand for this job now and how it’s likely to change, Spiceworks spoke with four tech leaders and hiring experts: Breckenridge, who heads a San Diego-based technology recruiting firm; Omair Manzoor, founder, CEO, and chief hacker at cybersecurity provider ioSENTRIX; Caitlin Wehniainen, president at placement On Cue HireOpens a new window ; and Deepali Vyas, global head of data and AI sector at talent advisory firm at ZRG PartnersOpens a new window .

What an application security engineer job entails

Application security engineers (often called AppSec engineers) are responsible for identifying and preventing security vulnerabilities in software applications. You’ll work alongside developers to build security into the software development lifecycle, rather than treating it as a final checkpoint before deployment.

Your primary job will be to find and fix vulnerabilities in software before attackers do. You’ll review source code, conduct dynamic testing against running applications, assess APIs, and work with your development teams to integrate security into the SDLC. Ideally, you’ll be involved while software products are being built. Identifying a security problem after customers have started using the software can quickly become costly.

Meanwhile, as AI creates productivity gains, it will also increasingly require securing all parts of a system that are impacted – cloud-native applications, APIs, third-party integrations, and AI-enabled software. Essentially, you’ll make sure that implementing AI doesn’t come at the expense of security.

Hiring demand for application security engineers

According to the Bureau of Labor StatisticsOpens a new window , the broader information security analyst category is projected to grow 21% between 2025 and 2035. But the tough reality right now is that AI and new security products are changing what companies need from this role. There are tools that can continuously monitor applications and alert teams to potential vulnerabilities, helping them address issues before they become bigger problems.

“I believe some of these positions will shift from hands-on engineering toward administering and owning those security tools – making sure they’re configured correctly, working effectively and using AI to help investigate flagged issues,” explains Wehniainen. “Application security will still be necessary, but that doesn’t automatically mean more engineering jobs. Candidates will need to adapt and demonstrate that they can validate what the tools find, make decisions about risk, and take ownership of resolving problems.”

What makes an application security engineer role rewarding

Among the most compelling aspects of this job is the combination of complex technical problem-solving and meaningful business impact. You’ll support engineers in helping companies grow and try new things safely, while keeping their customers, ideas, and good name secure.

Especially in larger environments, one major breach or AI-enabled issue with code can wreak havoc. Cybersecurity is also a field where the challenges are constantly evolving, making it particularly rewarding if you’re a naturally curious engineer who enjoys working on the cutting edge.

The bottom line: You’ll get to break things for a living — legally. Finding a critical vulnerability in a production application that could have exposed millions of records, and then working with the development team to fix it before anyone malicious finds it, is deeply rewarding. It’s also one of the few security roles where you see direct, measurable impact — the vulnerability you found yesterday is patched today.

Pay and benefits for application security engineer roles

You can expect a strong six-figure earning potential, especially as you gain experience and take on more responsibility. To provide perspective, the Bureau of Labor Statistics indicates a median yearly salary of $129,180 across the wider information security analyst field. This doesn’t represent application security engineer-specific compensation, as pay differs based on geographic location, company size, and job responsibilities.

Candidates should also look beyond base salary. Health benefits, retirement contributions, bonus opportunities, equity where offered, paid training, and flexibility can all affect the overall value of an offer.

Expected background experience

You’ll likely be an ideal candidate if you have development experience first. The best AppSec engineers are often developers who become curious about how their code could be attacked.

Understanding how software is built — including frameworks, languages, and deployment patterns — is what separates a great AppSec engineer from someone who just runs scanners. A background in web development, backend engineering, or DevOps with a pivot into security is the strongest foundation.

As AI tools become more advanced, there will be more opportunities for candidates who know how to manage them, investigate alerts, and resolve issues. Employers will evaluate candidates on what they’ve actually built, supported, tested, or improved, and which tools they’ve worked with directly.

Technology and business skills required for an application security engineer role

To stand out among candidates, you should have proficiency in at least two major programming languages, understanding of OWASP Top 10, experience with SAST/DAST tools, API security testing, and cloud-native application architectures.

On the business side, you should have the ability to prioritize findings by business risk rather than just CVSS score and to communicate with developers without creating an adversarial relationship. AppSec engineers who can’t work collaboratively with development teams get ignored regardless of how good their findings are.

Then comes the skill that can separate you from the pack: Explaining what matters. What needs fixing first? What could happen if you leave it? What is a practical solution? Organizations need someone who can turn technical findings into decisions.

Personality traits that make for preferred candidates

There are certain personality traits that will help your candidacy for this job. They include intellectual curiosity, analytical thinking, persistence, adaptability, and strong communication skills. You may often have to persuade software development teams to change how they work as they leverage more AI tools, which is widespread. That requires diplomacy and credibility, not just technical authority.

Also, the best engineers approach security as a collaborative discipline rather than an enforcement function. They understand that their job is to make developers more effective, not create unnecessary obstacles.

Certifications that will make you stand out

If you want to stock up on relevant certifications, the Certified Secure Software Lifecycle Professional, or CSSLP, is particularly valuable because it focuses on security throughout the software development lifecycle. From a recruiting perspective, a certification can strengthen your candidacy, but you still need to explain how you apply that knowledge. Being able to walk through a real problem and your approach to solving it makes a difference.

You should prioritize certifications based on career stage and specialization. The primary ones to focus on are CSSLP, GIAC GWAPT, and OSCP. For candidates pursuing broader security leadership, CISSP remains highly regarded. Cloud security credentials, including CCSP and relevant AWS or Azure certifications, can also strengthen a candidate’s marketability.

How to succeed as an application security engineer

If you’re fortunate to land this job role, you should become the person teams want in the room early. Understand the product, the customer, and the pressure the developers are under. Bring workable solutions. And keep a record of your results, including faster fixes, fewer repeat vulnerabilities, and better security practices adopted across teams.

Security work can be invisible when everything goes well, so you need to make your contribution visible. That’s how you build a case for more responsibility and promotion.

Build relationships with the development team and learn the business you’re supporting. Be willing to speak up, address problems head-on and communicate clearly. A high sense of urgency is critical in these positions because an application going down or being compromised can have a significant financial impact on a business.

Stay current on new tools and learn how to use AI effectively while keeping your skills hands-on. You want to understand what these tools can do, where they fall short and when you need to investigate further.

Where an application security engineer role may take your career

AppSec is one of the strongest career accelerators in cybersecurity. It builds skills that translate into security architecture, CISO-track leadership, or specialized consulting. The combination of development knowledge and security expertise will make you among the most versatile and in-demand people in the industry right now.

Success in this job can open doors into security architecture, product security leadership, cloud security, and management. Expanded expertise across risk management, governance, operations, and leadership creates a viable pathway to a chief information security officer position.
