Senior Windows IR Practitioner | Cyber Security Training

We're looking for experienced incident responders and blue team practitioners to join our Content Engineering team. Your job is simple in concept: take what you know from real world IR work and turn it into world class training content. You’ll take your years of real world experience and teach your peers and the next generation.

Job Responsibilities

• Research, design, and develop defensive cyber security training material with supporting hands‑on lab exercises (such as virtual machines and datasets for analysis).
• Draw on your real world IR experience to build realistic, scenario‑driven labs that reflect how attacks actually unfold in enterprise Windows environments.
• Develop and configure virtual machines and sample datasets for realistic cybersecurity labs.
• Collaborate closely with your team by sharing expertise, reviewing each other's work, and raising the quality bar collectively.
• Take charge of planning and designing portions of the content development roadmap.
• Collaborate with the Head of Content Engineering to continuously improve the content development process.
• Analyse industry trends in tooling and techniques and recreate them as teachable content.
• Strategically plan, review, and schedule content with our blue team content engineering team.

Technical Skills & Experience

To be considered for this opportunity, you must have significant hands on relevant cyber security industry experience in roles such as Incident Responder, Threat Hunter, Digital Forensics Investigator or L3 SOC Analyst. You should also demonstrate:

• Proven, hands‑on experience responding to real incidents in Windows environments.
• Triaging compromised endpoints, analysing forensic artefacts, and reconstructing attacker timelines from initial access through to impact.
• Solid grounding in Windows forensics and artefact analysis – event logs, registry hives, NTFS artefacts, and memory/disk forensics – with the ability to extract attacker activity from both live systems and forensic images.
• Working knowledge of offensive techniques used against Windows and Active Directory environments, including credential dumping, privilege escalation, Kerberos‑based attacks, and lateral movement, and critically, how to detect them in forensic artefacts, contain them during live response, and prevent recurrence.
• Hands‑on familiarity with attacker tooling and tradecraft – fileless execution, living‑off‑the‑land techniques (LOLBins), common exfiltration methods, and ransomware deployment patterns – including the TTPs of active APT groups and ransomware‑as‑a‑service operators.
• Experience with DFIR collection tooling such as EZ Toolset, Velociraptor, KAPE, or equivalent with an understanding of how to conduct IR at scale across enterprise environments.
• Strong verbal and written English communication skills, essential for conveying complex technical concepts.

Preferred Skills (nice‑to‑have)

• Any experience creating training content, writing documentation, or explaining technical concepts to others either formally or informally.
• Deeper expertise in one or more specialist areas: Active Directory attack paths (Kerberoasting, DCSync, ADCS), memory forensics (MemProcFS, Volatility), or advanced NTFS analysis.
• Creating challenges for capture the flags (CTFs).
• Experience leading, coaching, or mentoring others.
• Certifications such as GIAC Certified Incident Handler (GCIH), GIAC Certified Enterprise Defender (GCED), Security Analyst Level 2 (SAL2), Certified Forensic Analyst (GCFA).
