Role overview
First Advantage is seeking a Senior Offensive Security Engineer to join their Threat Management & Security Operations organization. This hands-on role requires thinking and operating like an adversary—continuously finding, exploiting, and helping remediate real-world weaknesses across products, cloud infrastructure, networks, and people. The engineer will design and execute penetration tests, red and purple team engagements, and adversary emulation exercises while partnering closely with Security Operations, Threat Intelligence & Hunt, Vulnerability Management, Application Security, DevOps, and Product teams to validate detection and response capabilities and measurably reduce enterprise risk at-scale.
Responsibilities
- Plan, scope, and execute internal and external penetration tests across web and mobile applications, APIs, cloud (AWS/Azure), networks, and infrastructure using real-world attacker techniques
- Design and run adversary emulation and red team engagements that combine multiple attack paths to accomplish objective-based goals, and partner with the SOC, Threat Intel & Hunt, and Detection Engineering on purple team exercises to validate and improve detection coverage
- Identify, validate, and safely exploit vulnerabilities — including chaining lower-severity issues into high-impact attack paths — and demonstrate tangible business impact in production-representative environments
- Model real-world threat actor tactics, techniques, and procedures (TTPs) mapped to the MITRE ATT&CK framework to test and strengthen organizational resilience, detection, and response
- Review and validate findings for accuracy, prioritize real-world exploitability and business risk, create remediation tickets, and partner with engineering teams to drive fixes and coordinate retests within policy SLAs
- Build and maintain custom scripts, tooling, and automation to scale offensive testing, and help operationalize continuous/autonomous testing platforms across the environment
- Produce clear, decision-ready reports and executive summaries that translate technical findings into risk and business impact for technical stakeholders, GCR/Audit, and executive leadership
- Support incident response and threat hunting efforts by providing offensive expertise, attack-path context, and adversary insight
- Contribute to the maturity of the offensive security program — developing repeatable methodologies, playbooks, and metrics that demonstrate progress over time
Requirements
- 5+ years of hands-on experience in offensive security, penetration testing, red teaming, or a closely related security engineering role
- Demonstrated expertise across multiple domains: web/mobile application, API, network, infrastructure, and cloud (AWS and/or Azure) penetration testing
- Strong understanding of exploitation and post-exploitation techniques, attack-path chaining, and objective-based adversary emulation
- Proficiency with industry-standard offensive tooling such as Burp Suite Professional, Nmap, Metasploit, and Kali Linux, along with vulnerability scanners
- Proficiency in at least one scripting or programming language (e.g., Python, Go, PowerShell, Ruby, or Bash) to build custom tools and automation
- Working knowledge of the MITRE ATT&CK framework and hands-on experience mapping engagements to adversary TTPs
- Excellent written and verbal communication skills, with the ability to present findings to both technical audiences and executive leadership
Nice to have
- Advanced offensive certifications (e.g., OSEP, OSCE³, CRTO, GXPN) and a track record of original security research, CVEs, or responsible disclosures
- Experience with cloud-native attack techniques and container/Kubernetes (EKS/AKS) and serverless security testing
- Experience operating or evaluating continuous/autonomous pen testing and breach-and-attack-simulation platforms
- Familiarity with detection engineering, SIEM/EDR platforms, and building purple team feedback loops into SOC content
- Knowledge of compliance and security frameworks relevant to our environment
- Experience mentoring junior engineers and helping mature an offensive security program
