Cyber Security Engineer
Salary: £55,000
Hybrid (London – Greenwich area)

Our client is deep into a major digital modernisation programme, reshaping their entire technology landscape to support a bold five-year strategy. As part of this transformation, they are building out a stronger, smarter and more innovative security capability — and this role will be central to that mission.

This is an opportunity to join a values-driven organisation with real scale, taking on a role where your decisions directly influence the resilience, safety and integrity of systems used by millions of people every year. If you want to work somewhere that actually takes cyber security seriously — where your expertise is listened to, backed, and invested in — this role delivers exactly that.

The Role

As Cyber Security Engineer, you’ll sit at the core of the security function, working alongside the Head of Cyber Security to strengthen the organisation’s security posture, protect critical infrastructure, and reduce risk across a diverse and complex environment.

You’ll take ownership of real security challenges — threat monitoring, vulnerability management, incident response, and continuous hardening of systems — while helping shape a maturing cyber function. This is hands-on, meaningful engineering work within a team that’s growing and being taken seriously at board level.

Key Responsibilities

• Threat Detection & Monitoring: Actively identify and analyse emerging risks across networks, applications and infrastructure.

• Incident Response: Support the creation, improvement and execution of response processes, ensuring swift containment and minimisation of impact.

• Security Assessments: Conduct regular audits and reviews, ensuring systems align to best practice and evolving security standards.

• Vulnerability Management: Own the identification, prioritisation and remediation of vulnerabilities, driving measurable improvements in resilience.

• Collaboration & Influence: Work closely with the Head of Cyber Security, operational teams and partners to implement safeguards and uplift security controls.

• Training & Awareness: Help embed a security-first culture by supporting colleagues, sharing knowledge and promoting safe working practices.

What You’ll Bring

• 3+ years’ cyber security experience within a sizeable or complex organisation.

• Strong understanding of threat analysis, vulnerability management and incident response.

• Experience with mainstream security tools (firewalls, IDS/IPS, scanning platforms, monitoring tools).

• Relevant certifications (CISSP, CEH, or similar) are highly desirable.

• Excellent communication skills — able to translate technical risk into clear, actionable understanding.

• High attention to detail and a proactive, investigative mindset.

• A team-oriented approach and the confidence to influence decisions across the organisation.

Why Join Our Client?

Our client is a large, well-established organisation with a genuine social purpose — and they invest heavily in their people, their technology and their long-term mission. Joining now places you right at the centre of a strategic digital uplift, giving you:

• A £55k permanent role with hybrid working.

• A long-term, stable environment with real engineering challenges.

• A security team that is expanding, supported and listened to.

• Access to strong professional development opportunities.

• A values-led culture where technology is central to future strategy.

This is an exciting role for a cyber specialist who wants to do significant, impactful work — not just maintain a dashboard. If you want to help build a stronger security landscape from the inside, this opportunity stands out.
