THE ROLE SHiFT is an innovative, ambitious, and impatient organisation. We're in a period of rapid growth and are already achieving significant successes alongside children and families. We are passionate about the ability of data, insights, and learning to help achieve this. We're a dynamic organisation with a strong focus on evidence and impact, and the Learning Team has already laid strong foundations for our data infrastructure. We are now looking for a Data Analyst to join our national team - a varied role, working alongside our second Data Analyst and the Learning & Insights Lead. This role is key in championing our learning culture at SHiFT, supporting our Voice, Participation, and Belonging strategy, and ensuring that our systems and reporting effectively demonstrate the impact SHiFT is having - not only with children and families, but also at a wider systems change level. On a fixed-term basis, this role will support the Learning Team by freeing up capacity for strategic and evaluative work, while also offering the opportunity to contribute to an exciting phase of growth in SHiFT's data infrastructure and learning capabilities. This role is perfect for someone looking to take a step up and build on existing skills in impact assessment, process evaluation, and thematic analysis. The Data Analyst will play a key role in streamlining quantitative and qualitative data processes, supporting accurate and efficient data collection across Practices, and helping us maximise the insights generated from our new, customised Salesforce data system. You will work closely with our data experts in local Practices (Practice Coordinators) and the wider SHiFT team. Therefore, you must be a proactive team player who is brilliant at building relationships, sees the value in working collaboratively, and enjoys problem-solving with others. You have a sharp eye for detail, sweat the small stuff, have a 'can do' attitude, and are ambitious to grow and make a difference as part of a practice-led systems change organisation. We are particularly interested in hearing from candidates with ideas for ethical and innovative methods in data collection with children and families. The successful candidate will bring both expertise and creativity to help improve data capture, analysis, reporting processes, and insight generation. Your experience will include working with CRM system(s) and data reporting tools, and you will be adept at managing multiple priorities in a fast-paced environment. If you enjoy making data fun and easy to understand, are comfortable working with stakeholders from non-research backgrounds, and get a kick out of improving processes - then get in touch. We aim to provide significant opportunities for personal growth, training, and career development, and are seeking someone with the ambition to play a crucial part in maintaining our data and evidence quality as we strive for systems change. EQUALITY AND DIVERSITY SHiFT is actively committed to the eradication of discrimination and disadvantage on the basis of race, religion, gender, gender identity, sexual orientation, disability, pregnancy and maternity, age, marital status and on the basis of socio-economic circumstances. We are determined for SHiFT to be a diverse and inclusive organisation that is enriched by a wide range of backgrounds, expertise, and experiences. We want to build a workplace that celebrates diversity and where everyone can feel valued, included, and involved. As a charity working within youth justice, we are keenly aware of the over-representation of children who identify as Black, Brown and Mixed Heritage or from Gypsy, Roma or Traveller Communities within the youth justice system. Challenging racism is a key priority for SHiFT. In seeking to achieve this, we understand the value and importance of recruiting and retaining a workforce which represents the children we seek to support. We therefore particularly encourage and welcome applications from people of diverse ethnic backgrounds, and we recognise that this group is currently under-represented within our national team. THE RESPONSIBILITES SHiFT's Data Analyst has responsibility for: Data Collection and Management: Support the effective use of SHiFT's Salesforce system, ensuring accurate, timely data entry and maintenance across local Practices. Work closely and creatively with members of our local Practice Teams (Practice Coordinators and Guides) to support the use of data for practice improvement and monitoring impact. Coordinate and quality-assure monthly data submissions, working closely with Practice teams to ensure consistency and completeness. Help to develop reporting tools, dashboards, or templates on and off Salesforce to support embedding learning back into practice and more widely to contribute to our ambitions for systems change. Help elevate the voices of children and families through innovative data collection processes (including arts-based and participatory methods). System Improvement and Efficiency: Identify and implement opportunities to streamline data processes. Contribute to the continuous improvement of SHiFT's Salesforce configuration, in collaboration with external developers and internal users. Help document processes and support training materials for system users. Navigate and innovate with different systems, including understanding the data recording systems used by Local Authorities and working with the Learning and Practice team to reduce duplication of data entry for practitioners. Learning and Insight Generation: Produce routine reports and data summaries for internal use, feeding into learning and influencing conversations. Support the Learning Team's efforts to use data for reflection, learning, and improvement both locally and nationally. Contribute to longer-term work exploring integration of data across education, youth justice, social care, and health systems. Building and holding relationships with external researchers aligned with SHiFT's mission to improve our data and insight capabilities. YOU WILL BRING Beliefs and alignment: The belief that all people are capable of change and that a relationship with a skilled practitioner can be a powerful driver of this. The belief that young people who display behaviours linked to offending can be supported so that they cease offending and meaningfully contribute to society. An alignment to a culture of high trust and high expectation where there are fewer rules, high levels of accountability, and a need for excellent performance from the entire team. An alignment to SHiFT's Values - ambition, courage, flexibility, and tenacity - which reflect the 'Breaking Cycles' ingredients (the foundations on which SHiFT is built). A preparedness to challenge the status quo and be positively disruptive in the pursuit of higher standards even when this is uncomfortable. Dynamism, tenacity, and determination - you are someone who does not give up until you succeed. You have a 'can do' attitude. Curiosity and a commitment to learning - comfortable in a fast-paced and aspirational 'start-up' context, and as part of a team that is committed to ongoing reflection, adaptation, and improvement.
