As a Penetration Testing Engineer, you will be conducting security assessments, working within our wider offensive security team, playing a key role in identifying and advising on technical findings across Nationwide’s estate.

You will be joining a growing team of dedicated and like-minded individuals where you will be expected to work independently and proactively to ensure that penetration tests are completed successfully, and the findings are understood by key stakeholders.

You will have demonstrable experience in delivering penetration tests from scoping through to reporting and post-test triage activity. You will be able to perform tests across a wide range of system and software stacks.

Communication skills are vital for the role. You must be comfortable explaining the risks of identified findings to technical and non-technical stakeholders.

We are happy to consider flexible working approaches to help you perform at your best.

At Nationwide we offer hybrid working wherever possible. More rewarding relationships are supported through our hybrid approach, bringing colleagues together across our UK wide estate, whilst also supporting generous access to home working. We value our time in the office to solve problems, to learn, and to feel connected.

For this role, you'll be based at your nearest regional office or hub. We value time spent together to connect with colleagues for collaboration so there will be a regular requirement to attend our London site approximately once per quarter. If you are based at an office location, you'll be expected to meet our hybrid working requirement of at least two days a week, or 40% of your working time if part-time, in the office**.** If your application is successful, your hiring manager will provide further details on how this works.

If we receive a high volume of relevant applications, we may close the advert earlier than the advertised date, so please apply as soon as you can.
