Senior Technical Consultant (Penetration Tester) CTL



Home based

Remote Working



IRM is a cybersecurity consultancy with a twenty year history of delivering world-class service to some of the UK’s biggest brands and organisations. Two years ago, IRM was acquired by the Altran Group – the world’s leading engineering and R&D Company, with around 45,000 employees around the globe and a turnover of around €3 billion.

Since the acquisition, we have moved into new and exciting areas of security, using Altran’s global account managers to welcome new clients through our doors.

We have opened a satellite offices in locations including Portugal and Santa Clara as we begin to position ourselves as a global player in cybersecurity. With Altran’s backing, we aim to be the leading security testing company for the world’s largest engineering brands.

The Technical Team

Our technical team is going through a period of organic growth, and currently we are looking to expand our team with both CTM and CTL level testers. The Altran acquisition has really started to change the way and the type of work that our penetration testers do. We are steadily moving away from standard CHECK work to explore new and more interesting areas within engineering – automotive, aeronautics and IoT, just to name a few.

We are in a unique position to be able to offer our consultants a wider variety of work than the vast majority of consultancies in the UK. This has allowed us to build a skills matrix and start to tailor progression and training to match your career ambitions. What work have we carried out recently? Physical testing on a major automotive manufacturer, testing on a cruise ship, testing apps on two major games consoles and three red team engagements within a national critical infrastructure organisation.

Each member of the team brings their own unique experiences and views so we positively encourage collaboration when needed. On larger engagements, we may assign multiple consultants. Every couple of months, the technical team get together for “Tech Night” – ordering in food, setting challenges for each other and sharing recent challenges they have faced. Recently, the team got together and discussed a recent red team event. They explored some of the methods used including the roadblocks and how they got around them; helping them to build our own red team playbook.

Since the Altran acquisition, we have kept all the things that made IRM a great company – brand identity and a SME culture that runs through the business. We don’t adopt a corporate culture and we are proud to have the same company ethos as we did twenty years ago. As part of the technical team, you are not one of a thousand consultants. Each member of team has the opportunity to shine and experience some truly weird, wonderful and unique projects.

The Role

As part of our Senior Team you will be instrumental in, not only performing a multitude of tests to an exceptional standard, but also to help with the learning and development of the team as a whole.

All senior consultants are scheduled into our duty week system. This creates a period of time where you will not be on client site to enable you to support with things in the office. This could include helping with interviews to strengthen the team, offering training to new starters or graduates and being on call to support less-experienced members of the team.

You will still play a large part in security testing – a mixture of web, infrastructure, physical and red team testing. Our testers just test, you won’t be asked to perform PCI work or Cyber Essentials!
