We are seeking a highly capable and technically confident Cyber Security Consultant to join our growing consultancy team. This role involves delivering deep-dive penetration testing and security assessments across a range of environments - including web applications, mobile platforms, corporate infrastructure, and cloud-native deployments.

Our consultancy engagements are tailored and often long-term, with a strong focus on working closely with our clients to improve their security posture in a meaningful and sustainable way. You’ll be involved in reviewing SDLC processes, CI/CD pipelines, firewall and network architecture, and delivering actionable recommendations embedded in real-world context.
The ideal candidate has a background in hands-on testing combined with a strong understanding of secure development and infrastructure principles.

Our clients expect - and we deliver - deep, contextual understanding of security issues, tailored technical insight, and meaningful engagement throughout the software and infrastructure lifecycle.

- Identify and contextualise vulnerabilities across varied tech stacks and environments.
- Produce clear, professional, and tailored technical reports with actionable mitigation strategies.
- Act as a trusted advisor to clients over extended engagements, supporting secure implementation efforts.
- Stay current with emerging threats, TTPs, and tooling relevant to offensive and defensive engagements.
You will have:
- Led project teams on consultative projects, with experience of delivering a range of solutions.
- Experience in penetration testing, security consulting, or technical advisory roles.
- Proficiency in application security testing methodologies (OWASP Top 10, API testing, session management, etc.)
- Hands-on experience testing and analysing mobile applications (static/dynamic analysis).
- Good working knowledge of cloud security architecture and common misconfigurations (IAM, storage, networking, secrets).
- Familiarity with DevOps tooling and CI/CD pipelines (e.g. Jenkins, GitLab, Azure DevOps, GitHub Actions).
- Understanding of SDLC best practices, secure development processes, and developer engagement.
- Ability to perform firewall rule reviews, segmentation validation, and network-level security assessments.
- Solid written and verbal communication skills, with the ability to produce high-quality client deliverables.
- Competency in scripting or automation.
Skills:
- Experience in container and Kubernetes security reviews.
- Knowledge of secure coding principles and secure SDLC integration.
- Familiarity with both manual and automated testing tools (e.g. Burp Suite Pro, MobSF, Terraform scanners).
- One or more relevant certifications (e.g. OSCP, CRTO, CREST, GIAC certifications).
