DESCRIPTION & REQUIREMENTS
On behalf of Companies House, we are looking for a Security Testing and Assurance Manager Inside IR35 for a 6-month contract based remotely.
Companies House drives confidence in the economy and makes the UK a great place to start, and run, a business.
SC Clearance is an essential requirement for this role, as a minimum you must be willing & eligible to undergo checks. Please note, due to the exceptional requirements of this position (short-term nature of this role and speed at which we require a postholder in situ) preference may be given to candidates who meet all of the essential criteria and hold active SC clearance.
As an executive agency sponsored by The Department for Business and Trade (DBT) we have the ability to play a leading role in the right against corrupt business practices by providing the transparency and clarity necessary for the UK to continue to be regarded as a world-leading place to do business.
Companies House is undergoing an historic change – to our systems, culture, services, and ways of working. Our people are at the heart of these changes.
The Economic Crime and Corporate Transparency Act (2023) gives Companies House the power to play a more significant role in disrupting economic crime and supporting economic growth.
These changes represent the biggest opportunity for Companies House in almost 170 years. This move will help us achieve the kind of culture we want – one which drives high performance and where our brilliant people can flourish.

- Own the triage, prioritisation, tracking, and remediation of security vulnerabilities through to resolution.
- Ensure security issues are accurately logged, assigned, and monitored using tools such as Jira.
- Develop and maintain security testing standards, methodologies, and quality assurance processes.
- Produce security risk assessments and provide clear recommendations to technical and business stakeholders.
