You will evaluate vectors, ensure reproducibility, and align work with learning objectives.

This fully remote role offers flexible hours, opportunities to mentor other engineers, and collaboration with Lab Managers and Content Architects on vector selection and content updates

Qualifications

• OSCP minimum, OSCE³ preferred (or at least one OffSec 300-level cert required).
• A Bachelor's Degree in Systems Engineering, Computer Science, Information Systems, and / or Information Assurance from an accredited institution/related specialized field, or equivalent practical experience.
• Demonstrable Active Directory and Cloud attack-path experience.
• Proficiency with infrastructure-as-code and configuration management and version control
• At least five or more years of experience as a Systems Engineer or in a Info-Sec related position (examples), with experience reviewing or approving others' technical security content:
• 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

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
• 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
