Senior Penetration Tester / Red Team Consultant - EY GDS Spain - Hybrid

As a Senior Penetration Tester / Red Team Consultant, you are part of the EY Cyber Security team delivering offensive security services that help clients validate and improve their security posture. You execute structured penetration tests and (where applicable) threat-led adversary simulations across applications, infrastructure, and cloud/hybrid environments, translating technical findings into clear, actionable risk reduction.

As a member of our team in the EY GDS Spain office in Malaga, you'll have a chance to extend your knowledge & experience by working on interesting projects with the newest technologies and approaches. You'll support clients in choosing the most suitable business solution and take part in digital transformation.

· Plan and execute penetration tests (internal/external), including web applications/APIs,
network/infrastructure, and cloud environments

· Define scope, rules of engagement, and test strategy with stakeholders; ensure safe execution and minimal
operational impact

· Perform security testing using a balanced approach of manual techniques and validated tooling; document
evidence and reproduce findings reliably

· Deliver high-quality reporting (executive summary, technical details, risk rating, remediation guidance);
support retesting and closure

· Conduct (or support) red team / purple team exercises where applicable, aligning scenarios to business risks
and adversary techniques

· Collaborate with defensive teams (SOC/Blue Team/IR) while ensuring appropriate separation and
independence of offensive and defensive activities

· Contribute to continuous improvement: refine methodologies, reusable playbooks/checklists, and
knowledge sharing

We look for ethical attackers who combine technical depth with maturity and discipline-clear scoping, clean
execution, and crisp communication. You care about impact: delivering findings that teams can fix and running
engagements that measurably improve resilience.
