Principal Cyber Security Consultant

United Kingdom

Overview

Leading the edge of transformation.

Join our organisation, where we have a huge variety of projects on-the-go at any one time. So when you start this role with us, it could take your career wherever your interests lie. You'll find everyone here is willing to pitch in and help because we all want you to succeed, and we're ready to help you grow.

When it comes to living your life, we want you to get the most out of it. So talk to us about all our flexible and remote working policies that can support your personal priorities. Also, ask us about some of our recent pledges for Women's'Equality, as well as being a 'Disability Confident' and 'Inclusive Employer.'

As a Cyber Security Consultant, you'll play a pivotal role in protecting Aerospace, Defence and CNI/OT clients from evolving cyber threats. You'll work on projects that shape national security, working alongside industry experts in a supportive, innovative environment. We offer clear pathways for career advancement, and professional development, and this role will suit a recently qualified professional who is looking to take their career to the next level and provide real world benefit to clients. In return, we offer a challenging and rewarding role, career development, an empowered and supportive working environment with a competitive reward package. We invest in your professional growth through certifications, training and leadership pathways. You will work on 'business as usual', technical refresh, and new project environments, applying technical knowledge and innovative thinking. You will help clients establish robust security governance, perform risk assessments, and deploy effective security controls and solutions aligned with business risk appetite.

The successful candidate will be a knowledgeable, enthusiastic and conscientious individual who has the relevant Information Assurance and Security qualifications, and experience in working in either Defence or CNI/OT. If you have strong cyber security fundamentals and are keen to develop expertise in Defence or CNI/OT, we'll support you with training and certifications. You will work on a range of client facing projects, large and small, but will also be expected to contribute to winning new business and managing delivery. Projects are likely to involve working on client sites, (although hybrid working allows us to be flexible), and may involve travel across the UK and, occasionally overseas.
