Opportunities in Cyber Security and Risk
Specialist Roles With Teams That Take Security Seriously
MCS Group supports organisations that want real cyber security capability and helps people move into roles where they can design and protect systems that scale, including advanced penetration tester jobs and offensive security functions. You get clear insight into architectural maturity, control gaps, ownership, delivery expectations, and long-term security plans, so both sides understand what is actually required to build effective and resilient security environments.
Security engineering depends on teams that can turn strategy into systems that actually hold up under pressure. We connect organisations with specialists who strengthen core architecture, close control gaps, and build secure foundations that scale. With clarity around maturity, tooling, and ownership, work moves from design intent to dependable protection that performs in real environments.
Effective detection and response rely on analysts who can cut through noise and act decisively. We support organisations seeking specialists who elevate signal quality, refine escalation paths, and keep visibility intact under pressure. With clear insight into tooling, response depth, and data workflows, teams move from alert overload to structured, meaningful defensive outcomes.
Governance performance relies on people who can translate frameworks into practice that hold up across teams. We connect organisations with specialists who clarify ownership, stabilise controls, and embed repeatable processes. With visibility on risk maturity, audit cycles, and operational impact, work moves from policy intent to reliable, consistent execution across the business.
Cloud and identity security depend on specialists who can turn architecture into secure, seamless access at scale. We match organisations with engineers who strengthen configuration, refine identity models, and support resilient cloud operations. With insight into platform maturity, permission design and long-term plans, work moves from conceptual strategy to dependable, secure delivery
Building Strong Security Teams Starts With Solving the Real Problems
Offensive capability grows by understanding root causes, not just reporting findings. Two testers may hold the same title but face entirely different technical landscapes. What slows a red team engagement isn’t what slows an application test, and what fails in exploitation isn’t what fails in remediation. You need guidance that recognises these nuances and connects you to specialists who can genuinely strengthen systems.
Insight Built on Real Testing Environments
Offensive security work lives in scope, access and decision-making. We focus on how testers explore environments, validate impact and communicate findings that engineering teams can act on. That perspective comes from working closely with professionals across penetration tester jobs and senior penetration tester jobs, giving us a clear view of what separates surface-level testing from work that genuinely strengthens security.

Effective offensive security is not about volume. It is about relevance.
- Testers who uncover real attack paths, not just known issues
- Ethical hackers who align findings to business risk
- Red team operators who simulate realistic adversary behaviour
We connect organisations with specialists whose work leads to practical remediation, not shelfware reports.
