Intervention Officer

We are Hestia. We make a difference.

At Hestia, we are guided by our core values and are dedicated to fostering an equitable, diverse, and inclusive organisation. Our mission is to empower individuals to rebuild their lives and achieve independence. Right now, we are looking for a Intervention Officer to play a pivotal role in our Criminal Justice Approved Premises service in Streatham

Sounds great, what will I be doing?

The role involves supporting residents in an Approved Premises by modelling positive behaviour, fostering respect, and maintaining a safe, healthy, and structured environment. A key aspect is acting as a keyworker, coordinating each resident's stay, delivering intensive casework, and addressing risk and support needs through regular sessions and daily engagement. The postholder also contributes to sentence plans in collaboration with probation, police, and external agencies, while encouraging compliance with rules such as drug and alcohol testing or curfews.

Alongside direct support, responsibilities include facilitating purposeful activities, preparing meals with residents, and ensuring the premises' health, safety, and security through observation, inspections, and effective communication.

Administrative responsibilities are central to the role, requiring accurate and timely record-keeping, information sharing, and adherence to confidentiality. The position also demands flexibility and initiative to manage emerging tasks while working closely with colleagues and management to maintain a psychologically informed environment that meets accreditation standards. The postholder must follow the Ministry of Justice and probation service protocols while aligning with Hestia's policies and values, consistently applying The Hestia Approach to create a positive, enabling culture within the service.

What do I need to bring with me?

You'll need to be able to demonstrate the core skills this role requires as well as match our values and mission. You don't have to tick all the boxes right away; the important thing is that you're willing to learn. We also value lived experience of the areas we support, so if you feel comfortable, please do mention this on your application.

Here's what the team will be looking for

This role requires significant experience working with vulnerable adults, preferably those with backgrounds in the criminal justice system, alongside a strong understanding of safeguarding and risk management. The postholder must have practical experience delivering direct keywork, supporting individuals with histories of offending behaviour through meaningful interventions that encourage positive change. A solid grasp of the causes and consequences of offending, combined with the ability to empower residents to make informed choices and move toward desistance, is essential.

Equally important is the capacity to engage effectively, communicate clearly, and apply professional authority while maintaining positive and pro-social relationships.

The position also demands resilience and adaptability in working with individuals affected by trauma, often displaying challenging emotions and behaviours. Strong teamwork skills are essential, with a willingness to contribute to both structured interventions and practical household tasks, setting a positive example for residents. High standards of literacy, numeracy, and record-keeping are required to ensure accurate documentation and professional communication. Finally, the role calls for optimism, decisiveness, and the ability to learn quickly, qualities that support residents' rehabilitation and reinforce the belief in their capacity for lasting change.
