Job Description

1. Role Purpose

The Data Developer role supports the delivery of digital and data‑driven solutions that help teams work more efficiently and reliably by improving how information is captured, processed, and presented. The role contributes to the build, maintenance, and support of technical products that reduce manual effort, improve data quality, and make information easier to access and reuse.

2. Deliverables

The role supports the delivery of data processing, reporting, visualisation, and automation solutions by contributing to the design, build, testing, and support of technical products within an agreed and defined scope of work.

Working with guidance from more senior team members, the role holder engages with stakeholders to help understand their information needs by gathering and clarifying requirements such as what data is required, where it originates, and how outputs are expected to be presented or automated. These activities focus on capturing and structuring information to support delivery, with decisions, prioritisation, and approval of requirements remaining with senior team members.

The role contributes to the delivery of new technical products, enhancements to existing products, and improvements to data flows, reports, or automated processes, following agreed standards, guidance, and ways of working. The role holder may also support the investigation and resolution of issues affecting existing products or data pipelines, under guidance, by helping to identify contributing factors, verifying data or logic, and supporting corrective actions. Ongoing system monitoring or operational ownership is not a primary responsibility of the role.

Working within agreed controls and guidance, the role holder applies standards consistently and provides feedback based on delivery experience to support their ongoing improvement.

Technical capability is expected to develop progressively through hands‑on work, learning, and support from the team.

Knowledge & Experience

• Experience of working with data, information, or systems as part of a role, including using IT tools to create, update, or work with structured information.
• Experience of understanding how processes, data, or tools operate within a work context, such as how inputs, rules, or constraints affect outputs, accuracy, or consistency, within the boundaries of the role.
• Experience of working with others to understand how information is created or used, including asking questions to clarify tasks, issues, or expectations.
• Experience of following defined procedures, guidance, or standards to deliver reliable and consistent outputs.

Essential Skills

• Demonstrable experience of working with information or data in a structured and methodical way, following given guidance to create, update, or support datasets, reports, templates, or automated outputs.
• Demonstrable experience of using IT tools to work with structured data or information, such as building, maintaining, or interrogating datasets, reports, or templates, using consistent structures and repeatable approaches.
• Ability to communicate clearly with colleagues or stakeholders, including explaining data, rules, assumptions, or limitations so others can understand what has been done and how outputs should be used.
• Experience of following defined processes, standards, and instructions to produce reliable and repeatable outputs, raising questions or issues when guidance is unclear rather than making assumptions.
• Demonstrable evidence of managing own workload within an agreed scope, prioritising tasks to meet deadlines and seeking support, review, or escalation when required.
• Demonstrable experience of learning and applying new tools, techniques, or ways of working as part of day‑to‑day activities, using guidance, practice, and feedback.

Desirable Skills

• Experience of working with structured data using tools such as databases, reporting tools, data visualisation software, or well‑structured spreadsheets.
• Experience of applying simple logic or transformations to data, for example through queries, calculated fields, structured spreadsheet models, or similar techniques, to produce repeatable and reliable outputs.
• Experience of contributing to, supporting, or improving automated or semi‑automated processes that reduce manual effort or improve consistency, under guidance or within an established approach.
• Familiarity with business intelligence, reporting, or dashboarding tools, including creating or updating views, reports, or user‑defined outputs from existing data sources. • Awareness of good practice when working with data or information, such as validating outputs, handling versions appropriately, and considering data quality or confidentiality when sharing information.
