Security Consultant jobs in United Kingdom

WithSecure delivers offensive-driven cyber security to defend organisations, society and people from real-world attacks and build resilience into their approach. Our people are a mix of technical and creative experts - diverse, talented, and passionate - working tirelessly to help us advance the industry with new ways of thinking. They lead their own development, in and out of the office.

We are recruiting for an experienced Security Consultant, with experience in architecture, design reviews, threat modelling and risk modelling. Ideally, with some hands-on technical pentesting experience too. This position is specifically for integration with one of WithSecure's strategic clients.

The job/the details

We need a Consultant who is comfortable in both technical and architectural conversations. You should have plenty of hands-on experience to draw on and should have strong technical fundamentals, including networking, infrastructure & applications - both on-premise and in the cloud (including SaaS). Experience with major cloud providers (preferably AWS) and SDLC toolsets is essential, and solid experience with infrastructure-as-code solutions is a benefit too. You will also ideally have strong hands-on security skills, from conducting pentests and security assessments. You'll be comfortable finding impactful vulnerabilities and explaining to clients how to fix them.

But you should also be familiar with the other side of the fence - with how solutions are designed, implemented and maintained throughout their lifecycle. Ideally, this experience will be from large enterprise clients (likely while working as a consultant for them) and you will be used to working with disparate, global teams, across both applications and infrastructure, quickly summarising risks, and thinking pragmatically about true business impact. Good communication skills are a must.

You will be working as part of a client's security team, and offering offensive security-minded thoughts and input on key design decisions. This will include areas such as:

1. What authentication and authorisation controls are used? Familiarity with technologies like OAuth and common identity providers, and the ability to explain common bypasses or flaws in their implementation.
2. How is data storage and transfer conducted securely? This should take into consideration the sensitivity of the data, technical specifics, architectural considerations, and any client-specific requirements.
3. Best practice input validation techniques - both in broad terms (allow-list, not deny-list; validate don't sanitise, etc.) and technically specific ones (specific programming language implementations).
4. Logging of security-relevant information, such as logging key user actions, logins, etc. as well as correct integration of log collection to centralised sources (e.g. SIEMs).
5. Supply chain risks. Discussing common supply chain/3rd party considerations with both application teams and 3rd party vendors.
6. Familiarity with cloud platforms, such as AWS and Azure, and how to securely host applications and workloads within them.
7. Ability to quickly get to grips with new or niche technologies and identify possible weaknesses.

You should be able to quickly understand industry-standard and client-specific design patterns across the range of topics above - such as using common libraries, known-secure configurations, etc. Where no such standards exist, you should be involved in helping create them - defining what good looks like.

For this specific client project, you will have an 80% utilisation target, meaning that 20% of your time will be spent on some of the following:

• Training (receiving, as well as delivering)
• Research
• Service Development
• Internal Security Assessments

The expectation is that the successful candidate will perform rotations on this client project for 12 months. During those 12 months, the candidate will still have opportunities to interact with and learn from WithSecure Consulting's broader team, through non-utilisation projects, time in the office, and hearing about or reviewing projects other consultants are involved in. At the end of the 12 month period, the opportunity to transition into a broader Security Consultant role will be available.

This is an office-based role - however, a number of the team choose to work from home most of the time. WithSecure do not mandate that people come into the office; we trust our team to get their work done wherever. However, we like to see you and the team do regularly attend one of our two offices, whether to learn from each other, for training or client projects, or to socialise. Our offices are:

1. London
2. Manchester

We solve complex cyber-security problems daily and to do so requires an interesting and comprehensive set of skills. To be successful at WithSecure and help our clients with their challenges you'll need the following:

• A passion for security

WithSecure's consultants are passionate about what they do. They have a passion for computers, hacking, security and most importantly, solving problems. If this wasn't your job, it would be your hobby. This passion is demonstrated in the technical excellence put into every project at WithSecure Consulting.

• Self-motivation

You're not going to be told what to do all the time - we will support your progression, but it will be up to you.

An ideal candidate will have:

• 2 years of industry experience
• Relevant certifications - primarily one of CREST CRT, Cyber Scheme Team Member, OSCP
• Other subject-matter specific certifications on topics such as cloud security

We're always considering motivated, proactive, problem-solvers at any level. So if you're keen on cyber security and want to make a start in the industry, please feel free to also apply and we can consider you for an Associate Security Consultant position.
