[Remote] Vulnerable Machine Engineer

Note: The job is a remote job and is open to candidates in USA. OffSec is a leading provider of continuous professional and workforce development in cybersecurity. The Vulnerable Machine Engineer role involves designing and building lab environments for hands-on learning, ensuring content quality and integrity, and collaborating with teams to enhance educational offerings.

Responsibilities

• Content design and build
• Researches and identifies topical, relevant attack vectors suitable for inclusion in OffSec labs, exams, and/or learning content
• Design and build VMs and multi-host environments from vectors across Linux and Windows, including Active Directory and Cloud attack paths
• Designs realistic scenarios and environment narratives that make each attack path plausible and discoverable through enumeration
• Ensures the range of vectors in each environment is appropriate to its stated difficulty level and learning objectives
• Maintains variety across the catalogue so that content remains distinct as it rotates through active use
• Quality, integrity, and reproducibility
• Review labs for unintended solution paths and confirms each is solvable by the intended route within its expected time frame
• Validates that machines are deterministic and reproducible in an isolated environment, including reliable reset and revert behaviour
• Deliberate selection and use of software and OS versions, monitoring deployed components so that content behaves consistently over its lifetime
• Documents the steps required to complete each machine, with difficulty assessed at a level of detail that supports competency mapping and certification review
• Collaboration
• Coordinates with the relevant team(s) to deploy, update, and retire content
• Coordinates with testing to ensure full coverage of both newly created and updated content
• Coordinates with the Lab team Manager and Content Architect on vector selection and exploit implementation within courses and learning paths
• Coordinates and make recommendations to keep content additions consistent across products
• Regularly communicates content additions, changes, and retirements to relevant stakeholders
• Senior scope
• Acts as a technical reviewer for lab concepts and builds produced by other Vulnerable Machine Engineers and community contributors, providing structured, actionable feedback
• Support and mentor other engineers on build standards, documentation quality, and content review practice
• Contributes across OffSec's lab and exam portfolio as priorities require, rather than to a single product
• Automation and tooling
• Creates and maintains automation that makes lab creation timely, consistent, and repeatable
• Evaluates new and emerging technologies to make recommendations on their introduction into the lab estate
• Create and maintain documentation for every lab, to a standard that allows any team member to rebuild it from the documentation alone, without assistance

• Demonstrable Active Directory and Cloud attack-path experience
• Proficiency with infrastructure-as-code and configuration management and version control
• Scripting proficiency (Python, PowerShell, Bash)

• Experience with Penetration Testing
• Experience with Bug Bounty Hunting
• Experience as a Systems Administrator with a variety of Operating Systems:
• MS Windows
• MS Windows Based Server Systems
• POSIX Server Systems
• Linux and Mac Desktop Environments
• Strong written and verbal communication skills with an ability to present technical ideas clearly to both technical and non-technical audiences
