Your responsibilities will include performing hands-on security testing, analyzing application behavior, reviewing source code, identifying realistic exploitation scenarios, and validating security controls across modern architectures. You’ll work closely with clients and internal teams to deliver high-quality technical assessments and actionable remediation guidance.

As a consultant, you’ll contribute throughout the full engagement lifecycle from scoping and test planning to execution, reporting, and client presentations. Success in this role requires strong technical depth, structured testing methodologies, effective communication skills, and the ability to adapt quickly to new technologies and environments.

  • Understanding of SDLC, CI/CD pipelines, and secure development practices
  • Experience using security assessment and code review tools such as Burp Suite, Semgrep, Git, AWS CLI, and API testing/debugging tools
  • Comfortable working across Linux, Windows, and macOS environments
  • Experience or strong interest in AI/LLM security, including prompt injection, RAG risks, insecure integrations, excessive permissions, and the OWASP Top 10 for LLM Applications
  • Strong written and verbal communication skills, with the ability to deliver clear, actionable findings and communicate technical risks to both technical and executive stakeholders
  • Experience following structured testing methodologies, documentation standards, and validation/retesting workflows
  • Strong collaboration and interpersonal skills when working with security, engineering, and client teams
  • Ability to manage multiple concurrent engagements while maintaining high-quality deliverables and attention to detail
  • Curious, adaptable, and professional mindset with a passion for continuous learning and emerging security trends

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
