4 Steps to Creating a Certified Ethical Hacker Job Description That Fits Your Needs

With a sample certified ethical hacker job description in hand, it’s time to write that job post. Although you don’t need a complete job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project. Below are some factors to consider when writing your job description:

1. Determine What Type of Certified Ethical Hacker You Need

Ethical hacking requires an intimate knowledge of computer engineering, computer systems, networking, information security, and data security principles, so certified ethical hackers are often highly specialized. They might focus on exploiting weaknesses in a specific operating system such as Windows, macOS, iOS, Android, or Linux.

They might also specialize in a particular aspect of IT security such as networking or hardware exploits. Projects should consider encompassing multiple specialties to provide a broad range of coverage to highlight weaknesses and potential system threats.

2. Employee vs. Independent Contractor vs. Agency

Certified ethical hackers can be hired in-house, contracted through an agency, or hired independently as a freelancer. A freelance certified ethical hacker might specialize in one area and could be employed to fill a single talent gap within your team. An agency will have a certified ethical hacker team that can help with various aspects of your project. It all depends on how granular you want to get with your talent staffing needs. Worker classification can be tricky, so check out our compliance services resources page for more information.

3. Experience

The more experienced a certified ethical hacker is, the more complex tasks they’ll be able to perform for your business. An entry-level certified ethical hacker might help as part of a team to carry out specific tests based on guidance from team leaders. Alternatively, you might consult with a senior certified ethical hacker to help assess projects and provide direction and leadership to new projects. Your project scope will determine the type of experience required for the job.

4. Industry

Certified ethical hackers form part of the broader cybersecurity industry. Cybersecurity overlaps with several industries, such as software engineering, cryptography, hardware development, and embedded systems design. Depending on project needs, multiple certified ethical hackers may be required to cover the wide range of potential attack vectors.

Hi, I'm Rumana — a cybersecurity professional from Dhaka with hands-on experience in WordPress security, malware removal, and ethical hacking. I'm currently transitioning into Security Operations, and I bring real technical skills that most entry-level candidates simply don't have yet. I've published two CVEs on the National Vulnerability Database in 2025 — one for a SQL injection flaw and another for an XSS vulnerability I discovered and responsibly disclosed. That's not coursework or labs. That's finding real vulnerabilities in real systems, which is exactly what SOC work demands. On the WordPress side, I handle everything from emergency malware cleanups and backdoor removal to SEO spam (Japanese/pharma injections), Google blacklist recovery, and full security hardening with Wordfence and Cloudflare. I don't rely on automated scans alone — I dig manually to find what scanners miss. My toolkit includes Burp Suite, Nmap, OWASP ZAP, WPScan, and Metasploit. I'm comfortable reading logs, identifying suspicious patterns, and writing up clear, detailed reports — skills that carry directly into SOC and incident response work. I hold a certified ethical hacking credential from CODEMANBD (2025), and I'm actively building my SOC foundation through hands-on threat analysis and vulnerability assessment practice. If you need someone who's genuinely passionate about security, fast to communicate, and already doing the work — not just studying it — I'd love to connect.

With 10+ years of experience across AI development, cybersecurity, and blockchain, I bring a combination most freelancers can't offer I think like an engineer and a hacker at the same time. ✦ CYBERSECURITY Certified OSCP | CRTO | eWPTXv2 I've led hundreds of penetration tests and security assessments for startups, enterprises, and regulated financial institutions. - Web Application & API Penetration Testing (OWASP Top 10, business logic flaws) - Network Penetration Testing Internal & External - Active Directory Security Assessments - Red Team & Assume Breach Engagements - Cloud Security Assessments - MITRE ATT&CK–based adversary emulation - Executive-ready reports, proof-of-concept evidence & free retests included All testing is manual-first no scanner noise, only real exploitable findings. ✦ AI DEVELOPMENT I've shipped full-scale AI products handling real users and real workflows. Here's what I build: - AI video generation platforms custom avatar creation, script-to-video, multilingual dubbing, and export-ready outputs - AI voice cloning & text-to-speech systems for content creators and media companies - AI avatar & digital human platforms for marketing, training, and e-learning use cases - Enterprise AI automation platforms natural language command execution, multi-task AI agents, and cross-department workflow automation - AI chatbots & virtual assistants integrated with WhatsApp, Telegram, Slack, and web apps - Custom LLM-powered tools document Q&A, internal knowledge bases, and AI copilots for SaaS products - RAG (Retrieval-Augmented Generation) pipelines for accurate, context-aware AI responses - AI content generation tools for social media, marketing copy, and video scripts - End-to-end AI SaaS products with subscription billing, user dashboards, and API integrations ✦ BLOCKCHAIN & WEB3 - Smart contract development & security audits - DeFi protocol builds and integrations - Web3 application development with security-first architecture - NFT platform development and token contract reviews ✦ WHY THIS COMBINATION MATTERS When I build your AI product, I'm already thinking about how it gets attacked. When I audit your systems, I understand the modern tech stacks powering them. That dual perspective is rare and it raises the quality bar of everything I deliver. If you want an AI builder who thinks like an attacker, or a security professional who ships real products — let's talk.
