• Experience working across the full software lifecycle — from design and implementation to support

• Familiarity with SQL Server, Elasticsearch, or similar database technologies

• Strong communication skills with the ability to liaise effectively with both technical and non-technical stakeholders

• Degree in Computer Science or related technical discipline

Nice to have

• Exposure to learning technology, education, or public sector environments

• Knowledge of Agile delivery methods
