Integration Engineer

At Charity Bank, we prioritise inclusion and fairness in our recruitment process. Our use of recruitment software helps mitigate unconscious bias by incorporating skill-based questions alongside CVs. Responses and CVs are anonymised and reviewed in random order by our hiring team to ensure an equal chance for all candidates, regardless of background. Demographic questions are strictly for statistical purposes, ensuring a balanced candidate pool. Opting out of these questions is an option.

The use of AI tools (e.g., ChatGPT or similar) is permitted in the application process. However, we advise against copying and pasting answers from AI tools, as this often results in generic responses. We encourage you to showcase your own experiences, voice, and style in your answers

We review all applications within two weeks after the closing date, so expect feedback shortly thereafter. If you require reasonable adjustments during the application process, please email us at recruitment@charitybank.org.

Disability Confident Scheme

Under the Equality Act 2010, a person with a disability is someone who has - or has had in the past - a physical or mental impairment which has a substantial and long-term adverse effect on that person's ability to carry out normal day-to-day activities.

As an Equal Opportunities and Disability Confident Committed employer, we actively encourage applications from people who consider themselves to have a disability falling within this broad definition. To access the Disability Confident Scheme, as an applicant with a disability/long term health condition/mental health condition, you are simply required to:

• Show that you meet the essential criteria described in the person specification.
• Answer 'yes' to both the following questions on the Bank's application form, 'according to the definition of disability do you consider yourself to have a disability?' and 'do you wish to be considered under the Disability Confident Scheme?'

You are not required to share the name or nature of your condition; you are simply stating the fact that you have a disability or long-term health condition/mental health condition. If you do not answer 'yes', your application will not be considered under the Disability Confident Scheme.

Adjustments for the application process and interview can be made if needed, so please contact us at recruitment@charitybank.org if you require this.

We are keen to recruit from as diverse a talent pool of applicants as possible, so the scheme gives you not a guaranteed job offer but an opportunity to be fairly and equally assessed in interview along with other candidates who meet the criteria for the role.

Hiring managers do not automatically know the details of your condition(s), they are allowed only to ask what adjustments you may need before the interview or when you are in receipt of a job offer.

Be reassured that any adjustments you require will be treated in the strictest confidence and will not form part of any aspect of the assessment.

If a job offer is made to you, we will discuss with you any adjustments that you may need in the workplace to enable you to perform the duties required. These will not be discussed at the interview.
