DWP. Digital with Purpose.

How would you lead penetration testing across one of the UK's largest and most complex digital environments?

We're looking for a Principal Penetration Tester to join DWP Digital, leading security testing, challenging our defences and helping make our services secure by design.

With around £280 billion in payments every year and a third of all UK BACS traffic, the scale of DWP is extraordinary.

It's security work at serious scale, with a purpose that matters, and we'd love you to join us on the journey.

What skills, knowledge and experience will you need?

  • Demonstrative experience of conducting structured penetration tests following 2 out of 3 of the following established frameworks (OWASP, NIST Cybersecurity Framework, PTES).
  • Experience in planning, executing and documenting security assessments with minimal supervision.
  • Understanding of NIST SP 800-115 for technical security testing and assessment.
  • Proven experience with commercial and open-source security testing tools - demonstrated ability to configure, operate and interpret results from various security assessment tools.
  • Evidenced experience in identifying, analysing and documenting security vulnerabilities. Understanding of risk assessment methodologies and ability to communicate findings to technical and non-technical stakeholders.
  • Proven experience working with security standards and compliance frameworks (ISO 27001, PCI DSS, SOC 2, NIST Cybersecurity Framework). Understanding of regulatory requirements and their impact on security testing. Familiarity with NIST risk management principles and controls mapping.
  • Demonstrable experience in client-facing roles, preparing technical reports and presenting findings. Proven ability to communicate complex security issues in clear, actionable terms.
  • Proven ability to build trusted relationships with senior stakeholders, using effective influencing and negotiation skills to navigate competing priorities, resolve complex issues and secure agreement on actions and outcomes.

You and your role

You'll be getting hands-on with penetration testing across a large and complex digital environment, looking for weaknesses, testing our defences and helping us stay one step ahead of emerging threats. From the start, you'll shape each engagement, deciding what to test and how to test it, using advanced exploitation and network-evasion techniques to really challenge our security.

As a technical leader, you'll be someone the wider team can turn to for guidance and mentoring. Supporting other penetration testers and sharing your expertise, you'll work closely with teams and senior stakeholders to make security part of how we design and build services, not something we simply check at the end.
